1 Introduction
1.1 Application Background
Scheme Crossrail
Applicant Crossrail Limited
Applicant Address 25 Canada Square, Canary Wharf, London, E14 5LQ
Site Address Ilford Yard, Ley Street, Ilford IG1 4BP Town and Country Planning Act Application for Replacement Greater Anglia Franchise (GAF) Training Centre with the provision of a new Back up Control Facility (BUCF) and Description demolition of the existing GAF training centre with permanent change of use to staff car park associated with the adjacent Ilford railway yard and associated works.
1.2 Terms of Reference This Planning Statement has been prepared in support of a planning application for a replacement new Greater Anglia Franchise (GAF) Training Centre incorporating a new Back up Control Facility (BUCF) with 2.1m high palisade fence to the building perimeter, the demolition of the existing GAF Training Centre, a permanent change of use to staff car park to provide replacement car parking spaces, with permanent hard standing, provision of lighting and retaining walls, utilities and all other associated works, connection to existing sewers in Ley Street, removal of earth bund, with onsite shrub planting. These are all works outside Crossrail Act limits. This application is made under Section 57 of the Town and Country Planning Act 1990 (as amended). The proposed works require consent under the Town and Country Planning Act because they are not permitted by the Crossrail Act 2008. This is due to their location being outside the Limits of Deviation (LOD) and Limits of Limits of Land to be Acquired or Used (LLAU) identified on the plans that accompany the Crossrail Act 2008.
1.3 Introduction to Crossrail
Crossrail is a major new cross-London rail link project that has been developed to serve London and the southeast of England. Crossrail will support and maintain the status of London as a World City by providing a world class transport system. The project includes the construction of a twin-bore tunnel on a west-east alignment under central London and the upgrading of existing National Rail lines to the east and west of central London. The project will enable the introduction of a range of new and improved rail journeys into and through London. It includes the construction of seven central area stations, providing interchange with London Underground, National Rail and London bus services, and the upgrading or renewal of existing stations outside central London.

Town and Country Planning Act Application - Planning Statement RED/11/8 Document Number C161-MMD-T-XST-CR112_WS129-50010 Rev 3.0
Crossrail will provide fast, efficient and convenient rail access to the West End and the City by linking existing routes from Shenfield and Abbey Wood in the east, with Maidenhead and Heathrow in the west. Crossrail will be a significant addition to the transport infrastructure of London and the southeast of England. The Crossrail route is illustrated in Figure 1. It will deliver improved services for rail users through the relief of crowding, faster journeys and the provision of a range of new direct journey opportunities. The project will also have wider social and economic benefits for London and the southeast of England.

1.4 Introduction to the Planning Statement This Planning Statement presents the planning policy context for the planning application. Section 1 introduces the relationship to the wider Crossrail project. Section 2 provides a description of the site and surroundings. Section 3 considers the planning history of the application site. Section 4 provides details of the proposed works that are included in this planning application. Section 5 provides a summary of the relevant National, Greater London and London Borough planning policies which form the local development plan and the material considerations for the determination of the proposed development. Section 6 forms the case for justifying the proposed development. A Design and Access Statement is included at Appendix A; and a copy of the Crossrail Construction Code at Appendix B. Appendix C includes an Energy Assessment, Appendix D includes a BREEAM Pre- Assessment and Appendix E includes a Transport Statement.
1.5 Planning and Administrative Context The Crossrail Act 2008 (the Act) provides powers for the construction and operation of Crossrail. The Act deems planning permission to be granted for the works authorised by it subject to conditions set out in Schedule 7 to the Act. Schedule 7 includes conditions requiring various matters to be approved by the relevant Local Planning Authority (LPA). Schedule 1 to the Act describes the ‘scheduled works’ that are authorised by the Act. Schedule 2 authorises the construction of works ancillary to the railway (‘ancillary works’).

Town and Country Planning Act Application - Planning Statement RED/11/8 Document Number C161-MMD-T-XST-CR112_WS129-50010 Rev 3.0
In order for the works to benefit from the deemed planning permission, scheduled works need to be within the LOD both horizontal and vertical for that work. Ancillary works need to be within LLAU and within the scope of the Crossrail Environmental Statement (ES).
Development of the design proposals as part of the Ilford Yard Stabling Project has resulted in some elements of the proposed works being outside the Crossrail LOD and LLAU. As a result, planning permission under the Town and County Planning Act 1990 (as amended) will be sought for the works outlined above.
1.6 Crossrail Construction Code
Paragraph 1.4 of the Crossrail Environmental Minimum Requirements (EMR) states that “any nominated undertaker will be contractually bound to comply with the controls set out in the EMR and as may be developed during the passage of the Act through Parliament”. The scope of the EMR encompasses the Crossrail Construction Code.
The proposed works are to be carried out, as all work relating to Crossrail, in accordance with the Crossrail Environmental Minimum Requirements (EMR) which incorporate, as Annex 1, the Crossrail Construction Code. This represents a stringent construction management code.
‘Construction’ in the Code includes all site preparation (including site investigation and remediation, where appropriate), demolition, material delivery, excavated material disposal, waste removal and all related engineering and construction activities. The EMR and Crossrail Construction Code form the incorporated mitigation relevant to the works, including for example, dust and noise control measures. A copy of the Construction Code is included at Appendix B of this Planning Statement for information but does not form part of this application.

2 Location Characteristics
2.1 Location and Setting The existing Ilford depot occupies a large site in the north east of Greater London adjacent to the Great Eastern Mainline (GEML), approximately eight miles east of London Liverpool Street Station. The site is located between Ilford railway station (to the west) and Seven Kings railway station (to the east). The site lies wholly within the London Borough of Redbridge and is located to the east of Ilford town centre. Griggs Approach (an elevated highway over the railway) separates the site from the edge of the town centre. The site has been used for railway activities for many years. The Greater Anglia Franchise (GAF) and Bombardier Transportation are currently based at the site.
2.2 Description of Application Site and Context The existing Ilford depot site contains the following main buildings, from east to west: the GAF Light Maintenance Depot Building; a small yard control building operated by GAF; a paint shop; Workshop B; a train washing facility; Workshop A; a training facility with adjacent stores building used by Bombardier Transportation; a wheel lathe building; and a GAF Training Centre located within the western part of the site. The site also comprises stabling trackwork and headshunts to the east and west; together with some smaller ancillary buildings located to the east of the site. Photograph 1 provides an aerial view of the application site in the context of the existing Ilford depot site.
The northern part of the site contains sidings and adjacent to the site boundary there are residential properties. The existing staff car park is also located within the northern part of the site and is accessed from Ley Street. At the eastern end of the site, beyond the GAF Light Maintenance Depot Building, is Aldborough Road South. To the east of this road, there are residential properties and the Palmer Catholic Academy.
Adjacent to the western boundary of the site is Corkers Path, beyond which is Griggs Approach, an elevated road over the railway lines. There are a number of high rise buildings to the west side of Griggs Approach. To the south of the site is the GEML, beyond which there are a mix of uses including residential, industrial, car parking and a waste transfer depot.
There is a Site of Nature Conservation Importance and a Green Corridor outside the application site boundary to the south of the depot. Both are linear designations and follow the route of the GEML. The Green Corridor allocation widens in the west of the site.

3 Planning History
3.1 Description of Planning History and Context The application site is part of the wider Ilford depot, which has been used for railway activities for many years. There are therefore historic planning applications for various railway related developments within the wider site. Other elements of the Ilford Yard Stabling Project which were the subject of separate applications to the London Borough of Redbridge include:
LPA Application Application Description Dates Reference Reference Type
1494/12 RED/11/1 Schedule 7 Construction Arrangements Approved 29 (Construction for the construction of the August 2012 Arrangements) Ilford Yard Stabling Project

Fencing, vehicle restraint/protection barriers, raise/lower barriers height restriction barriers, bollards; Earth works and retaining walls; Lighting; CCTV support columns; and Other ancillary works, as required.
There is limited planning history for the site to the east (location of the new GAF training centre and BUCF). An application by Crossrail for minor works to the western area (location of the proposed new car park) including new access and parking arrangements at the same site was approved on 16 November 2012 (LPA reference 1699/12). This previous permission will be superseded by the current application. A further application by Crossrail for 180 Ley Street for the demolition of the existing buildings and a permanent change of use from a builder’s yard to a depot staff car park associated was approved on the 27th February 2013 (Ref 2697/12). This permission will not be implemented if the current application is approved. A Schedule 7 application (LPA reference 1495/12) associated with works within Crossrail limits to the west of the site (adjacent the proposed car park set out in this application) was approved on 4th September 2012. The application included 19 car parking spaces to the west of the proposed Logistics and Stores Building. Crossrail will still be implementing this permission which will tie in with the parking spaces proposed within this TCPA. A further schedule 7 application will be submitted for this area within limits for the proposed lighting and bollards shown in the proposed car park layout plan drawing T-DDA-CR112 SD007-1- 40102. The 19 car parking spaces will also be reconfigured to correlate with the new parking proposals within this application.

4 Description of Works
4.1 Works Forming Part of TCPA Application
This Planning Application includes the following works:
Extension to the south west corner of the existing GAF Light Maintenance Depot shed with a replacement two storey GAF Training Centre building including the provision of a Backup Control Facility (BUCF) for Crossrail route operations;
2.1m high metal palisade fence around the boundary of the new GAF training centre and BUCF.
Demolition of existing buildings including the GAF Training Centre and adjacent modular building to the west of the depot; removal of earth bund and trees to south- east of existing GAF Training Centre;
Removal of existing steel container located to east of existing GAF Training Centre (as shown in Photograph 8);
Upon completion of worksite use, the worksites will either be restored or developed for the new car parking provision or the new GAF Training Facility /BUCF; Provision of permanent hard-standing and associated surface water drainage including connections to existing sewers at Ley Street.
Existing hedge to the north of the area to remain with provision of soft landscaping onsite;
Provision of retaining walls;
Installation of steel lighting columns (10m high);
All other associated works.
4.2 Replacement GAF training centre including the provision of a backup control facility (BUCF) The replacement GAF Training Centre building is needed to accommodate the demolition of the existing GAF Training Centre to the west of the site (required in order to provide replacement car parking outlined further in section 4.3 and 6.3 of the planning statement) which forms part of this application. The training facility is used by Greater Anglia for inductions and technical training sessions. Temporary training facilities within the existing GAF buildings will be provided whilst the new training centre is being developed.

Town and Country Planning Act Application - Planning Statement RED/11/8 Document Number C161-MMD-T-XST-CR112_WS129-50010 Rev 3.0
The BUCF is needed to control the whole Crossrail route should there be any issue associated with the primary Crossrail control centre at Romford. The BUCF is a stand-by facility to be used on an infrequent basis. There will be 6 people using the BUCF however this will only happen if the need arises to use that facility.
4.3 Provision of Permanent Staff Car Park The proposed parking spaces will provide replacement car parking provision for existing GAF and Bombardier Transportation car parking spaces which will be displaced as a result of Crossrail works within the Ilford Yard complex, (authorised under the Crossrail Act), and will provide additional spaces required specifically to service Crossrail operations at the site. Rationalisation of parking on the site has been on-going for several years. Today there are approximately 130 spaces on the site overall. A total of 52 car parking spaces are proposed with associated circulation to be provided in the permanent car park subject to this planning application. The standard car parking spaces will be 4.8 long x 2.4m wide. A landscaping strategy has also been produced for the car park with the provision of trees off site and soft landscaping, details of which are outlined further in the Design and Access statement (Appendix A). The existing staff only pedestrian access off Corkers Path will remain with minor work to provide new access controls and CCTV coverage to the existing gate.
4.4 Provision of Retaining Walls Two sections of new retaining walls, approximately 1 metre in height with a guardrail above, are proposed adjacent to Corkers Path to accommodate a level difference between this part of the site and the footpath. A further section of retaining wall (maximum height 1.5 metres, with a guardrail above) will be provided to the north of the Paint Shop Building to accommodate for a level difference. The retaining walls will have a concrete finish. These works will be executed in conjunction with other retaining wall sections within Crossrail limits of deviation, consented under other permissions described above in section 3.1.
4.5 Demolition works and removal of Earth Bund and Steel Container
The demolition works will include:
Existing GAF Training Centre;
Modular building and steel container adjacent to existing GAF Training Centre
Removal of earth bund and trees to south-east of existing GAF Training Centre
Redundant plant adjacent to GAF Light Maintenance Depot;
4.6 Drainage and Utilities Works In the vicinity of the existing GAF Training Centre, there is drainage works proposed that are located outside of Crossrail Act limits. Foul and surface water drainage will be located to the north of the GAF training centre, running in an east-west direction; and surface water

Town and Country Planning Act Application - Planning Statement RED/11/8 Document Number C161-MMD-T-XST-CR112_WS129-50010 Rev 3.0
drainage is proposed to the south of the proposed car parking area and existing GAF training centre. Foul and surface connections are proposed to be made to the existing public sewers within Ley Street. The connections will be subject to separate agreement with Thames Water. A maximum discharge rate of 7 litres per second has been agreed in principle with Thames Water. There are proposed attenuation tanks which will be located in areas that are within Crossrail limits. Such works are not associated with this planning application.
4.7 Temporary Works – For Information only and not for Approval Upon completion of demolition and site clearance works (to the west of the site), and prior to permanent use as a car park, the site will be used for the temporary lay down of materials and provision modular worksite accommodation. The temporary uses on the site will run between August 2013 to December 2016 following which the modular accommodation will be removed from the site. The scale of construction traffic associated with the contractor’s compound use of the site will be small and will not result in any adverse impacts on the local roads in close proximity to the site or the wider network. The site will be used as an integral element of the adjacent Ilford yard, and there will be no change in construction traffic volumes or routes as outlined in the Redbridge Lorry Management Plan submitted as part of the Schedule 7 Construction Arrangements for Ilford yard (1494/12 RED/11/1). Activities for the temporary compound use will include the loading and unloading of materials from goods vehicles associated with Ilford yard construction works. As the proposed temporary works are of a very limited scope they will have limited if any impacts upon the environment or upon the surrounding area. Temporary use of the site will be undertaken using permitted development rights under Part 4 of the Town and Country Planning General Permitted Development Order 1995.

5 Policy Context
This section provides a summary of the key planning policies at the national, regional and local levels which form the development plan for the London Borough of Redbridge and will be material planning considerations used in the determination of the proposed development by the LPA. This section focuses only on those policies that are relevant to this planning application and a justification of the proposed development, in terms of its compliance with policy, is provided in Section 6 of this Planning Statement.
5.1 National Level Policy National Planning Policy Framework (NPPF) (March 2012)
The NPPF sets out the Government’s planning policies for England and how these are expected to be applied. Planning applications must be determined in accordance with the development plan, unless material considerations indicate otherwise. The NPPF must be taken into account in the preparation of local and neighbourhood plans, and is a material consideration in planning decisions. The NPPF states that the purpose of the planning system is to contribute to the achievement of sustainable development; and identifies that there are three dimensions to sustainable development, namely economic, social and environmental. The NPPF states that these dimensions give rise to the need for the planning system to perform a number of roles, as follows: an economic role – contributing to building a strong, responsive and competitive economy, by ensuring that sufficient land of the right type is available in the right places and at the right time to support growth and innovation; and by identifying and coordinating development requirements, including the provision of infrastructure; a social role – supporting strong, vibrant and healthy communities, by providing the supply of housing required to meet the needs of present and future generations; and by creating a high quality built environment, with accessible local services that reflect the community’s needs and support its health, social and cultural well-being; and an environmental role – contributing to protecting and enhancing our natural, built and historic environment; and, as part of this, helping to improve biodiversity, use natural resources prudently, minimise waste and pollution, and mitigate and adapt to climate change including moving to a low carbon economy.
In assessing and determining development proposals, the NPPF requires LPAs to apply the presumption in favour of sustainable development.
Paragraphs 29 -41 of the NPPF replace the previous advice contained within Planning Policy Guidance 13 (PPG13) on Transport. The NPPF states that transport policies have an important role to play in facilitating sustainable development and in contributing to wider sustainability and health objectives. The NPPF also indicates that the Government recognises that different policies and measures will be required in different communities and opportunities to maximise sustainable transport solutions.

The NPPF gives significant weight to the promotion of good design in new development. It provides a series of design principles, which should be used for all development. Paragraph 56 indicates the importance that the Government attaches to the design of the built environment; and states that: “good design is a key aspect of sustainable development, is indivisible from good planning, and should contribute positively to making places better for people.” The NPPF requires that new development should be planned to avoid increased vulnerability to the range of impacts arising from climate change. When determining planning applications, the NPPF requires LPAs to ensure that flood risk is not increased elsewhere. The NPPF states that applications for minor development and changes of use should not be subject to the Sequential or Exception Tests, but should still meet the requirements for site specific flood risk assessments. Site specific flood risk assessment is required for proposals of 1 hectare or greater in Flood Zone 1; all proposals for new development (including minor development and change of use) in Flood Zones 2 and 3, or in an area within Flood Zone 1 which has critical drainage problems (as notified to the local planning authority by the Environment Agency); and where proposed development or a change of use to a more vulnerable class may be subject to other sources of flooding. When determining planning applications, the NPPF advises that LPAs should aim to conserve and enhance biodiversity.
To prevent unacceptable risks from pollution and land instability, the NPPF states that planning policies and decisions should ensure that new development is appropriate for its location. The NPPF requires the effects (including cumulative effects) of pollution on health, the natural environment or general amenity, and the potential sensitivity of the area or proposed development to adverse effects from pollution, to be taken into account; and where a site is affected by contamination or land stability issues, responsibility for securing a safe development rests with the developer and/or landowner.
5.2 Greater London Level Policy
5.2.1 The London Plan – Introduction
The latest London Plan was published in July 2011 and forms part of the development plan for Greater London. It is the overall strategic plan for London and sets out an integrated economic, environmental, transport and social framework for the development of the capital to 2031.
5.2.2 The London Plan - Crossrail Related Policies
Policy 6.4 ‘Enhancing London’s Transport Connectivity’ states that: “…the Mayor will work with strategic partners to improve the public transport system in London, including cross- London and orbital rail links to support future development and regeneration priority areas, and increase public transport capacity by implementing Crossrail, the Mayor’s top strategic transport priority for London.”
Paragraph 6.21 indicates that Crossrail is essential to delivery of the strategic objectives of the London Plan. The Plan recognises that demand for public transport into and within central London is nearing capacity and that the expected employment growth during the Plan period will further increase this demand; and if this is not addressed, it will threaten continued development and employment growth.

5.2.3 The London Plan - General Policies The following extracts of policies of the London Plan relate to planning decisions for all developments within London. Policy 5.2 – Minimising Carbon Development proposals should make the fullest contribution to Dioxide emissions minimising carbon dioxide emissions in accordance with the following energy hierarchy: Be lean: use less energy Be clean: supply energy efficiently Be green: use renewable energy The Mayor will work with boroughs and developers to ensure that major developments meet the following targets for carbon dioxide emissions reduction in buildings.
Non-domestic buildings: Year Improvement on 2010 Building Regulations 2010 – 2013 25 per cent 2013 – 2016 40 per cent 2016 – 2019 As per building regulations requirements 2019 – 2031 Zero carbon
The London Plan also states a detailed energy assessment should be included.
Policy 5.3 - Sustainable design Development proposals should demonstrate that sustainable design and construction standards are integral to the proposal, including its construction and operation, and ensure that they are considered at the beginning of the design process. Policy 5.12 - Flood risk Development proposals must comply with the flood risk assessment management and management requirements set out in PPS25 (now replaced by NPPF) over the lifetime of the development and have regard to measures proposed in Thames Estuary 2100 (TE2100 – see paragraph 5.55) and Catchment Flood Management Plans. Policy 5.21 - Contaminated land Appropriate measures should be taken to ensure that development on previously contaminated land does not activate or spread contamination. Policy 6.13 - Parking The Mayor wishes to see an appropriate balance being struck between promoting new development and preventing excessive car parking provision that can undermine cycling, walking and public transport use. The maximum standards set out in Table 6.2 in the Parking Addendum to Chapter 6 of the plan should be applied to planning applications. Policy 7.3 - Designing out crime Development should reduce the opportunities for criminal behaviour and contribute to a sense of security without being overbearing or intimidating. Policy 7.13 - Safety, security Development proposals should contribute to the minimisation of and resilience to emergency potential physical risks, including those arising as a result of fire, flood and related hazards. Policy 7.19 – Biodiversity and C: Planning Decisions - Development proposals should a) wherever Access to Nature possible, make a positive contribution to the protection, enhancement, creation and management of biodiversity; b) prioritise assisting in achieving targets in biodiversity action plans (BAPs)… Policy 7.21 - Trees and Existing trees of value should be retained and any loss as the result woodlands of development should be replaced following the principle of ‘right place, right tree’.

5.2.4 The Mayor’s Transport Strategy (May 2010) The Mayor’s Transport Strategy sets the policy framework for transport in London. The Mayor’s transport vision is as follows: “London’s transport system should excel among those of world cities, providing access to opportunities for all its people and enterprises, achieving the highest environmental standards and leading the world in its approach to tackling urban transport challenges of the 21st century.” Six goals are identified to set out how this vision should be implemented. The Mayor’s transport strategy should: support economic development and population growth; enhance the quality of life for all Londoners; improve the safety and security of all Londoners; improve transport opportunities for all Londoners; reduce transport’s contribution to climate change and improve its resilience; and support delivery of the London 2012 Olympic and Paralympic Games and its legacy. The Strategy states that: “Crossrail is the biggest transport project in Europe and a scheme of national importance that will provide a rail spine across London from east to west. It is needed to underpin the most rapid economic growth areas of London and will be a significant capacity addition to the transport network.”
5.3 London Borough Level Policy
5.3.1 Introduction
The application site lies within the administrative boundaries of the London Borough of Redbridge. The Redbridge Local Development Framework (LDF) replaced the Redbridge Unitary Development Plan (UDP) in 2008. The LDF delivers the spatial development strategy for the Borough and builds upon existing local and regional strategies and initiatives.
The London Borough of Redbridge Proposals Map indicates that the site to the west (location of proposed new car park) is included within the tall buildings policy area (Borough-wide policy BD2). The site to the east (proposed location of new GAF training centre and BUCF is also within the tall buildings policy area.
The Proposals Map indicates that the application site to the west is also adjacent to the Ilford Metropolitan Centre (and the Ilford Town Centre Area Action Plan boundary), situated to the west of the site.
There is a Site of Nature Conservation Importance and a Green Corridor allocation (see Borough-wide policy E2, below) located to the south of the overall planning application site (both the area to the west and the east), within the southern part of the wider Ilford depot site. Both are linear designations following the route of the Great Eastern Main Line. The

Proposals Map also indicates that the Great Eastern Main Line is Crossrail safeguarded land.
5.3.2 The London Borough of Redbridge Core Strategy (2008)
The Core Strategy Development Plan Document (DPD) was adopted by the Council in March 2008. A five year review is currently being undertaken.
The Core Strategy sets out an overall spatial strategy for the Borough and provides general guidelines on the types of development that the Council wants to see in Redbridge and where they are to be built. The following extracts of Strategic Polices are relevant to this planning application: Strategic Policy 1: Overall Growth will be harnessed to help achieve the Council’s vision, by Growth focussing new development upon the hierarchy of town centres as follows: (a) The Metropolitan Centre of Ilford will be the primary area of growth within Redbridge, accommodating a range of new development including housing, retail, office and other commercial, cultural, health, leisure and community facilities. New development will be expected to improve and enhance the public realm. (b) In the District Centres… (c) The Local Centres... Development will not be permitted in areas subject to natural hazards such as flooding and geotechnical instability, unless exceptional circumstances exist and appropriate mitigation is proposed. Strategic Policy 2: Green Nature conservation, protection and enhancement of open space and Environment mitigation of climate change will be achieved by…: (f) Protecting the floodplain and reducing and managing fluvial, tidal, surface water and all other forms of flood risk. (g) Minimising the release of pollutants (including CO2) and other contaminants (including silt and sediment) into the Borough’s air, waterways and soil. (h) Protecting and where feasible extending habitat throughout the Borough and to areas beyond, by maintaining existing trees, native vegetation and open space and providing new areas of such vegetation (to include by linking existing fragmented areas) for the benefit of wildlife… Strategic Policy 3: Built The Council will ensure that the Boroughs built environment will be of Environment a high quality that serves the long-term needs of all residents by: (a) Preserving or enhancing the character or appearance of conservation areas. (b) Preserving the architectural or historic interest of Listed Buildings and their settings. (c) Protecting, enhancing and preserving sites of archaeological interest and their settings. (d) Requiring all new buildings to be designed to a high standard and to be in accordance with principles of sustainable construction to minimise energy use and the production of greenhouse gases. (e) Requiring spaces around buildings to be well-landscaped, safe, healthy and accessible to all. Page 24 of 50 Document uncontrolled once printed.

Town and Country Planning Act Application - Planning Statement RED/11/8 Document Number C161-MMD-T-XST-CR112_WS129-50010 Rev 3.0
(f) Requiring all new development to respect the amenity of adjoining properties and the locality generally. (g) Promoting water conservation and re-use and improving the water quality through sustainable drainage systems and control surface runoff. Strategic Policy 6: Movement A transport network that supports a prosperous economy and socially and Transport cohesive community, reduces car dependence, encourages sustainable transport, improves air quality and reduces greenhouse gas contributions to climate change will be achieved Through… (a) Reducing the need to travel, by locating new development…within the hierarchy of own centres and other locations in accordance with Strategic Policy 1. (b) Promoting walking, cycling and use of public transport by: (i) Locating new development within close proximity to public transport nodes… (c) Further reducing the need to travel and providing an efficient and effective transport network by…: (iv) Assessing the impact of development proposals on the transport network and requiring the preparation of Green Travel Plans on all major developments. (v) Requiring new developments to provide safe and functional off- street car parking spaces and adequate access to such parking areas from the public highway.
5.3.3 The London Borough of Redbridge Borough Wide Primary Policies DPD (2008) This Borough-Wide Primary Policies DPD provides an extension to the more general strategic policies identified in the Core Strategy. It provides a detailed set of planning policies which the Council uses to assess planning applications. The aim is to ensure that all new development contributes positively to the social, economic and environmental well- being of the Borough.
The following extracts of Borough Wide Primary Polices are relevant to this planning application: Environment Policy E2 – Nature The Council will protect and where appropriate enhance the Conservation Borough’s natural heritage, including the Blue Ribbon Network, and landscape features. Planning permission will be refused for development having an adverse impact on Sites of Nature Conservation Importance, Heritage Land, Green Corridors (as identified on the Proposals Map), the Roding Valley, protected trees and on important species… Policy E5 – Flooding and Water Proposals for development in the flood plain will be refused where Quality they increase flood risk or conflict with the sequential approach to flood risk as set out in any Strategic Flood Risk Assessment prepared for the Borough. Where development is proposed in an area at risk from flooding from any source, the applicant will be required to provide a Flood Risk Assessment, including the following: 1. An assessment of the potential impact on the development of Page 25 of 50 Document uncontrolled once printed. All controlled documents are saved on the CRL Document System © Crossrail Limited Decal Template: CRL1-XRL-Z-ZTM-CR001-50018 Rev.1.0
Town and Country Planning Act Application - Planning Statement RED/11/8 Document Number C161-MMD-T-XST-CR112_WS129-50010 Rev 3.0
flooding from any source. 2. An assessment of whether the development will increase flood risk elsewhere. 3. Measures to deal with the effects and risks. 4. Demonstrate that any flood risk can be successfully managed with minimum impact on the environment and that any flood mitigation works can be funded for the entire lifetime of the development. Proposals which pose an unacceptable risk to the quality of the water catchment, groundwater or surface water will also be refused. Transport Policy T1 – Sustainable New development will be granted planning permission in locations Transport close to public transport nodes. Elsewhere new development will only be granted planning permission where it incorporates measures that demonstrate a reduced reliance on private vehicles. Planning permission will not be granted for development, which would increase trip generation excessively so as to result in an adverse impact on traffic congestion within the local and strategic road network (including motorways) or public transport system. Policy T5 – Parking Standards Car parking will be sought in accordance with the maximum standards set out in Schedule 3 of the DPD. Proposals should also make provision for motorcycle parking. Where a lesser standard of parking provision than that shown in Schedule 3 is proposed, applications will be considered on the basis of adherence to green travel planning measures, levels of public transport accessibility, the availability of public parking, the character of the area and the nature of the development proposed. All car parking spaces shall be a minimum of 4.8m by 2.4m in size. When proposals for parking areas are devised, due consideration should be given to Policy T6 (service and delivery areas). For non- residential development that includes over twenty spaces, at least 5% (or 2 car parking spaces –whichever is the greater) of all car parking must be reserved for use exclusively by people with disabilities and in possession of a blue badge. All spaces that are reserved for blue badge holders should be located as conveniently as reasonably practical and meet the relevant standard. For all other development, appropriate levels of disabled parking should be provided in line with the needs of the likely users. Cycle parking spaces should be provided in a convenient and safe location, preferably near to the main entrance of a development and be sheltered from inclement weather wherever possible. Proposals for major development must include for the provision of secure lockers and storage areas and such provision will be considered favourably for other development. Policy T6 – Service and The Council will only grant planning permission for new development Delivery Vehicles where there is adequate, safe and functional provision for: 1. Service and delivery vehicles (including lorries and articulated vehicles) required as part of the normal functioning of the development 2. Emergency services vehicles such as fire engines and ambulances 3. Visitor “drop off” and “pick up” areas (e.g. for parents at crèches and schools) Such provision may include access to and from the public highway, as well as on-site parking and manoeuvring areas. All Development Policy BD1 – All Development Proposals for all forms of development must incorporate high quality Page 26 of 50 Document uncontrolled once printed.

sustainable construction techniques reflecting the Council’s Supplementary Planning Guidance on Urban Design (September 2004) and Sustainable Design and Construction (May 2005). To gain planning permission, a development proposal must: 1. Be compatible with and contribute to the distinctive character and amenity of the area in which it is located. 2. Be of a building style, massing, scale, density and design appropriate to the locality. 3. Realise the potential of the land. 4. Contribute to local architecture and design quality. 5. Protect or enhance the effects on valuable habitats and species. 6. Ensure that landscaping is an integral element in layout design, taking account of existing physical features (e.g. trees, hedgerows, walls, etc.). Where appropriate, trees and shrubs should augment the amenity and appearance of the site. 7. Not prejudice the amenity of neighbouring occupiers by unreasonably restricting sunlight, daylight or privacy to their properties. 8. Create safe and secure environments and reduce the scope for fear and crime by taking into account the Police Service’s “Secure by Design” Standards. 9. Be designed to meet the needs of all and include provision for disabled access to, and within public areas. 10. Include appropriate provision for the storage and collection of waste and recyclable material. 11. Demonstrate that there is no significant adverse impact on surrounding uses in terms air, water, noise pollution, and of fume and smell nuisance. 12. Where appropriate provide evidence that there is capacity in utility infrastructure, including water, foul drainage, sewerage and 13. Where appropriate, demonstrate that there is the provision to connect with broadband information technology infrastructure.
5.3.4 Crossrail Corridor Area Action Plan (2011)
Crossrail is a nationally important project the benefits it will bring include significant stimulus to local economies and this is recognised in Redbridge by the Crossrail Corridor Action Plan.
5.3.5 Other Borough Guidance
The London Borough of Redbridge has also produced Supplementary Planning Guidance (SPG) and Supplementary Planning Documents (SPD) which elaborate on policies in the Council's DPDs. SPD of relevance to this planning application are:
Sustainable Design and Construction SPD (2012); and
Trees and Landscaping SPD (2006).
The Sustainable Design and Construction SPD provides guidance on how development in Redbridge should be designed, built and occupied in order to achieve best practice standards of sustainable design and construction. It expands on Strategic Policy 3 of the Core Strategy and Borough-wide policy BD1. Guidance is provided for the energy and reducing carbon emissions; climate change adaptation; reducing the risk of flooding and the demand for water; reducing waste and increasing recycling; minimising air, land, water and Page 27 of 50 Document uncontrolled once printed.

noise pollution; biodiversity and the natural environment; and encouraging sustainable modes of transport. The SPD also sets out the requirements for new developments; for major developments (1000 sq.m and above) BREEAM Excellent standard should be met. As this application is for a new building which exceeds this floorspace threshold an Energy Assessment is provided to accompany the application (Appendix C).
The Trees and Landscape SPD provides further details on the Council’s policy approach to trees and landscaping. The policies aim to ensure that all development and tree protection measures contribute positively to the character and image of the Borough by retaining and protecting existing trees, planting additional trees where appropriate and by providing well- designed, quality landscaping. The SPD contains specific guidance how to integrate trees and landscaping into the design and layout of new developments; the level of detail and expert input that developers will be expected to provide in regard to landscaping and trees, when seeking planning permission; and how to protect existing trees during construction phases.

6 The Case for the Proposed Development
6.1 General Principles Crossrail is one of the country’s key infrastructure projects. It will significantly increase the capacity of the rail network into and across London and the South East. The Mayor’s Transport Strategy sets the policy framework for transport in London and identifies Crossrail as the biggest transport project in Europe and a scheme of national importance that will provide a rail spine across London from east to west. The Strategy states that Crossrail is needed to underpin the most rapid economic growth areas of London and will be a significant capacity addition to the transport network. Crossrail is also essential to the delivery of the strategic objectives of the London Plan. The general principle for the use of the land for railway infrastructure works is well established. The site has been used as a railway depot for many years and remains in this use. The use of the wider Ilford Yard site as a site for the stabling of Crossrail trains has been established through the Crossrail Act 2008. The works that are the subject of this planning application form part the Ilford Yard Stabling Project. The proposed development will facilitate the delivery of this part of the Crossrail project. The proposals support the delivery of the NPPF and the London Plan which identifies that Crossrail is essential to delivery of the strategic objectives of the Plan.
6.2 Case for Permanent Staff Car Park and development of replacement GAF and BUCF Policy 6.13 (Parking) of the London Plan indicates that the Mayor wishes to see an appropriate balance being struck between promoting new development and preventing excessive car parking provision that can undermine cycling, walking and public transport use. The proposed car parking will directly replace that displaced as a result of the Crossrail works taking place at Ilford Yard. Once the works compound use ceases in 2016 the site would be vacated and the permanent use would then be implemented - namely development of the staff car park. Crossrail works at Ilford yard will not only displace existing (BT and GAF) parking at the depot site, but will also introduce its own parking requirement. The need to provide this parking has led to the requirement for this planning application. The site partly falls outside of Crossrail limits of deviation therefore requiring the submission of a TCPA. The proposed development will facilitate the delivery of a key component of the Crossrail project. Railway depots do not fall into a classification of the Use Classes Order, and past experience dictates that they fall into the sui generis use. As a sui generis use applies, there is no defined parking standard, rather, it is appropriate to justify parking provision on: Operational requirements of the depot facilities, and the staff who will work there, in particular the level of shift and night-time working when it would be more difficult for workers to arrive / depart by public transport, and The number of designated spaces at other railway depots in London of a similar size and operational function.

The Ilford Yard Stabling Project design impacts on the existing car parking provision within the wider Ilford depot. As a result of the proposed design, car parking spaces used by GAF and located to the west of the existing wheel lathe building will be displaced; in addition, car parking spaces currently used by Bombardier Transportation will be displaced as a result of the proposed Logistics and Stores Building. The depot is in 24 hour operation with shift working. The depot staff – both the existing train operating company, and the proposed new Crossrail operating company train drivers and other staff - are required to make journeys to and from work outside the normal operating hours of public transport. For this reason, the depot site needs a relatively large amount of parking in order to remain operational – i.e. for the train drivers and other essential staff to travel to and from their place of work at times when public transport is not fully operational. There are currently 130 existing car parking spaces located at the overall Ilford depot site (the pre-existing condition before Crossrail). As a result of the proposed works already approved – such as construction of the new paint shop and the new operations facility - a number of those spaces will be lost, and the requirement therefore exists to not only reprovide those spaces, but to also to provide for the Crossrail Train Operating Company too (CTOC). Crossrail undertakes not to implement the planning application for depot parking at 180 Ley St (see below). The introduction of a new train operating company on site with an additional 90+ staff will not significantly increase the overall level of parking from the pre-existing conditions – from 130 to 166 spaces - an overall increase of only 36 spaces. This accounts for 71 new spaces in the proposed car park (52 outside limits) but also allows for reductions in spaces elsewhere in the depot. The depot currently functions with two companies operating from the site (Great Anglia franchise and Bombardier) with 130 parking spaces. The fact that the Crossrail TOC will also operate from the depot in the future will introduce additional requirements for both staff and parking. The very constrained nature of the depot site means that all three companies on site will in the future be required to work with a sub-optimal level of parking provision. There is no requirement to provide bicycle parking spaces within the application site as such facilities will be provided elsewhere within the Ilford yard site. There will however be one disabled parking space (the latter will be located within limits). The location for the new GAF training centre and BUCF to the east of the site is considered to be the only suitable alternative within the depot site. The GAF Training Centre will be co- located near existing GAF facilities, consolidating the facilities associated with the Greater Anglia Franchise within one area. Proposed Parking Provision Previous approved applications at llford Yard for car parking on the site include: 180 Ley Street (ref 2697/12) which proposed 33 spaces (now proposed not to be implemented if the current application is not approved). An application for minor works directly overlapping with the application site (ref 1699/12 approved) included the provision of 13 car parking spaces (now proposed not to be implemented).

Town and Country Planning Act Application - Planning Statement RED/11/8 Document Number C161-MMD-T-XST-CR112_WS129-50010 Rev 3.0
In addition there is some potential to reconfigure the existing northern car park which is within Crossrail LLAU in order to provide some additional provision of 19 new car parking spaces. This provides a total of 65 car parking spaces while the current application seeks approval for 52 car parking spaces. An application for 180 Ley Street for the demolition of the existing buildings and a permanent change of use from a builder’s yard to a staff car park for the depot was approved on the 27th February 2013 (ref 2697/12). Provision of staff car parking at 180 Ley Street is no longer feasible, due to a number of factors including the fact that no suitable alternative location for the building company can be found. Therefore, Crossrail are considering alternative sites in order to meet essential parking requirements. Crossrail will not progress with the 180 Ley Street permission if this current application is approved. Seeking an alternative location for depot parking via this application ensures retention of the existing builder’s yard business in situ. Parking Summary The proposed new staff car park is considered both suitable and appropriate due to a number of factors, including: Parking will need to be made available for three railway companies on site, including for many staff working overlapping shift patterns, when full public transport is not operational. This is the only area available within the depot where this amount of parking can be accommodated. It is overall a more suitable and sustainable location for car parking, away from any residential receptors. There will be limited impact on neighbouring areas in terms of light pollution. The depot is operates 24 hour a day; the proposed location would therefore limit further impact on nearby residents in terms of noise. The site will accommodate an overall majority of the depots’ car parking spaces in one location. The proposed site for car parking is considered to be safer, within an enclosed secure area. A more suitable location compared with the previous proposal for parking at Ley Street i.e. for minimal impacts associated with noise or disturbance to surrounding areas.

6.3 Layout, Siting and Design of proposed new car park The car park has been designed to allow easy and safe access for both cars and pedestrians as it includes separate access points for both. The principles employed to ensure easy and safe access for all are considered to be compliant with the BD1 policy, point 9 (Borough-Wide Primary Policies DPD). During construction, the temporary compound will be accessed through the existing main entrance to the Ilford depot site off Ley Street. The new car park will also be accessed through the existing main entrance to the Ilford depot site off Ley Street (please refer to the proposed layout plan drawing T-DDA-CR112 SD007-1-40102). All new car parking spaces will be clearly marked out in white thermoplastic road marking material. The standard car parking spaces will be 4.8 x 2.4m and will therefore be in compliance with policy T5 (Borough-Wide Primary Policies DPD). Safety has been a key factor in the design of the car park. There is existing lighting as well as new lighting proposed (shown in drawing T-DDA-CR112 SD007-1-40102) which would ensure the site is well lit at all times. There is an existing CCTV mast at the entrance, facing the site. The car park will be for use only by Depot staff, and therefore will not be available to the general public. Safe routes for pedestrians will be clearly marked out. The pedestrian route runs along the west and north boundary of the site. (Please refer to drawing T-DDA- CR112 SD007-1-40102 for the location of the pedestrian route). There is an existing controlled pedestrian access to the site which would remain a controlled access point from Corkers Path allowing only depot staff to enter. The principles employed to ensure the area is safe in considered to be compliant with 7.13 of the London Plan. The layout of the car park would allow for a HGV turning area to the east of the car park near the logistics and stores building (this will be located within Crossrail limits and is therefore not part of this planning application). Only one HGV vehicle per week is anticipated. There would be a designated area to the south east of the site to be kept clear for emergency vehicles only. The site has been designed to create a safe and secure environment, therefore is considered to be compliant with local council policy BD1, point 8 (Borough-Wide Primary Policies DPD). The proposed landscaped areas are shown on drawing T-DDA-CR112 SD007-1-40102. The scheme includes retaining some of the existing landscaping i.e. existing hedge towards the north of the GAF Training Centre, and existing hedge towards the western end which will be retained as a form of screening to the site. The landscape strategy includes provision of soft landscaping i.e. new shrub planting towards the north and south boundary of the site. Off-site tree planting is also proposed as a replacement for trees which must be felled from within the site. These are shown in the drawing mentioned above. The landscaping strategy is considered to be in compliance with local council policy on Trees and Landscaping SPG (2006). Proposed landscaping will help ensure that a high standard of design and layout is achieved. Section 6.7 sets out how the landscaping strategy has evolved in discussion with the Local Planning Authority. Please also refer to Appendix A for further access, design and layout considerations.

6.4 Alternative Ilford Yard car park sites A number of alternative sites were considered before selecting the current site to ensure the most suitable location for the car park. Site 1: The possibility of extending the existing staff car park in the north of the Ilford yard site on the narrow strip of land between the rear gardens of properties on Ley Street and the depot tracks was investigated. Although this has some potential to be developed for car parking, due to the narrow and constrained nature of this strip of land the full number of required parking spaces cannot be achieved through extension of the car park. Site 2: The option of providing a single storey “decked” car park on the existing northern car park site was considered. However, that option was discounted on the basis of visual intrusion to the rear of existing properties on Ley Street. Site 3: Although a large multi storey car park lies just to the west of the application site, the Ilford Town Centre Area Action Plan (May 2008) identifies it as an opportunity site (OS19) in which the preferred use is for a mixed use redevelopment including housing with "re- provision of car parking". With up to 270 residential units proposed on that site it is clear that public parking would be very limited compared to the present arrangements. Thus Crossrail would be unable to rely on that facility for staff parking as the likelihood is that this would not be available for the use by depot staff for parking at some stage in the future. Site 4 An application for 180 Ley Street for the demolition of the existing buildings and a permanent change of use from a builder’s yard to a staff car park associated was approved on the 27th February 2013. As stated above Crossrail will not be progressing this option (if the current application is approved) and have considered alternative sites to meeting parking needs. The proposed site for the provision of car parking is considered a more suitable site, located away from any residential areas. The works associated with this application include the extension to the south west corner of the existing GAF Light Maintenance Depot shed with a replacement GAF Training Centre and co-located Backup Control Facility (BUCF) to the east of the site. There will be an overall increase in floorspace for training of 1030m² The extension will be in keeping with the existing Light Maintenance Depot building, with the use of profiled steel cladding matching the existing building. The extension will be two storeys, approximately 8m tall with a flat roof. The design of the new GAF Training Centre and combined BUCF is seen to be appropriate to the locality and will not impact any surrounding uses; it is not located in a sensitive area. The new GAF Training Centre will have aluminium framed double glazed tilt and turn windows. The roofing materials will match the existing. Therefore the design of the extension is compliant with local council policy BD1 (The London Borough of Redbridge Borough Wide Primary Policies DPD). The signage associated with the new GAF training facility will include large illuminated signage, with the Greater Anglia logo. Please refer to drawing C161-MMD-S-DDC- CR112_SD007_Z-35503 for further details on the design and appearance of the extension. The GAF Training Centre and BUCF floor layout plan (drawing C161-MMD-S-DDC- CR112_SD007_Z-35501) shows the BUCF will be located on the ground floor and will Page 33 of 50 Document uncontrolled once printed.

Town and Country Planning Act Application - Planning Statement RED/11/8 Document Number C161-MMD-T-XST-CR112_WS129-50010 Rev 3.0
include an equipment room and a control room (covering an area of 156.86 m²). The rest of the ground floor (560.13 m²) and the first floor (721.45 m²) will be associated with the GAF Training Centre which includes some classrooms for training purposes. The design of the new GAF training centre and BUCF was careful in considering the safety of the intended users of the building. Pedestrian access to the site will be through the existing car park located on the east side of the depot site. There is a safe pedestrian route which runs from the east car park around the GAF Light Maintenance Depot. This safe route will be connected to a safe paved area around the boundary of the new GAF training centre, which would also have a 2.1m metal palisade fence running around it to ensure users of the GAF Training Centre are not in any danger from the railway tracks (please refer to drawing C161-MMD-T-DDD-CR112_SD007_1-40109 for the fence detailing).
Service and delivery vehicles will use the car park to the east off Aldborough Road South where any deliveries would then be man hauled through to the new facility using the existing safe pedestrian route (compliant with Policy T6 of The London Borough of Redbridge Borough Wide Primary Policies DPD). Visitors to the site would be required to sign in and will go through an induction process, before being escorted to the new training facility.
6.5 Energy Performance / Sustainable Design Crossrail’s aspirations are for the new GAF Training Facility building to meet the BREEAM rating of ‘Excellent’ and to achieve a 25% reduction in carbon emissions over that stated in Approved Document Part L2A 2010. The building will have extensive insulation measures as well as double glazing throughout. An initial BREEAM evaluation and Energy Assessment (Appendix C/D) indicates that a rating of “Excellent” should be achievable and the “lean building” approach will deliver significant gains towards the 25% reduction target. However, it is accepted that additional measures to increase energy efficiency and reduce GHG emissions are likely to be required to achieve the 25% target. Such measures may comprise one, or a combination of, the following: improved building fabric/ air permeability; solar photovoltaics; solar hot water; and air source heat pump (for heating only). More detailed energy and sustainability performance assessments will be undertaken as part of the detailed design development process and measures will be incorporated in the design as appropriate in order to comply with the London Borough of Redbridge’s’ Supplementary Planning Document: Sustainable Design and Construction requirements in relation to energy and carbon emissions Therefore the proposal includes consideration of sustainable development principles and is compliant with local council Strategic Policy 3 Built Environment, point d (The London Borough of Redbridge Core Strategy, Sustainable Design and Construction SPD and London Plan Policy 5.2 Minimising Carbon Dioxide emissions.
6.6 Transport Statement The Transport Statement in Appendix E sets out how the works associated with this specific application will not have any major impacts on the local and wider road networks. Demolition of the existing GAF training centre (to the west of the site) will have up to approximately six construction vehicles per day. Construction of the car park is expected to have up to one or two construction vehicles per day. The construction of the new GAF

Town and Country Planning Act Application - Planning Statement RED/11/8 Document Number C161-MMD-T-XST-CR112_WS129-50010 Rev 3.0
training centre and BUCF (to the east of the site) is expected to have up to two HGV’s per day. Considering these works will be of relatively short duration the impact of the works on the existing transport network is seen to be minimal and small scale in relation to the whole of the Crossrail Ilford scheme. The approved lorry routes (Ref 1494/12) between the site and the wider Highways network will be used for material deliveries and removal.
6.7 Trees, Landscaping and Biodiversity
An Extended Phase 1 Ecology Survey has been undertaken for the overall depot site. This concluded that there are no particular habitats including any notable or protected plant species of significant conservation importance present within the depot site. There is a Site of Nature Conservation Importance and a Green Corridor allocation located to the south of the planning application site boundary, within the southern part of the wider Ilford depot site. Both are linear designations following the route of the Great Eastern Main Line. The proposed development will not affect the connectivity function of the Green Corridor or the habitat within the area. Whilst there will be some removal of vegetation including shrubs and trees to the west of the GAF Training Centre and the earth bund, there will not be a significant impact on the ecological resource because replanting will take place within the application site and off site. The proposals will result in the loss of small groups of shrubs and trees and an individual tree (on the west of the site, where there will be a new car park). An Arboricultural Statement (Document C161-MMD-T-XST-CR112-WS129-50005) has been produced in support of this planning application. The tree, a sycamore, is identified as a tree of moderate quality and value. The tree group (sycamore trees) is of low quality and value and the shrub areas are of no arboricultural value. There are no trees or landscaping that will be affected by the works proposed to the east of the site (the extension of the GAF Light Maintenance Depot to accommodate the new GAF Training Centre and BUFC).
Under the previous application for minor works approved by Redbridge (1699/12) condition 3 specifically required a scheme showing the adequate replanting of trees on the proposal site shall be submitted to and approved in writing by the Local Planning Authority. The same areas of trees and shrubs are to be removed in the current planning application and therefore there is no substantive difference between this and the earlier approved scheme.
Crossrail and the London Borough of Redbridge have therefore agreed a strategy to compensate for the loss of the trees as outlined below.
To mitigate the loss of the sycamore trees, 6 new trees will be planted off site. The new trees are proposed to be planted along Corkers Path. Please see drawing number T-DDA- CR112 SD007-1-40102 for the location of the new trees. The application also includes measures to retain existing planting where possible i.e. retaining existing hedges to the north and the west of the site to create a form of screening to the site. New replacement native species planting is proposed for the land within the site. The planting would include shrubs. The shrub planting is also intended to mitigate for shrub and grassland lost within the northern area of the wider depot site. The species proposed for the new planting would be selected to reinforce the local townscape character and to enhance biodiversity. Species would include hawthorn, hazel, guelder rose, field rose, English oak, field maple and ash. The landscaping strategy is considered to be in compliance with local council policy on Trees and Landscaping SPG (2006). Page 35 of 50 Document uncontrolled once printed.

The proposed development is to be carried out, as all work relating to Crossrail, in accordance with the Crossrail Environmental Minimum Requirements (EMR) which incorporate, as Annex 1, the Construction Code. These documents form the incorporated mitigation for the proposed development. Section 10 of the Construction Code relates to Ecology and Nature Conservation and requires procedures to be implemented to control and limit disturbance to areas of nature conservation interest and protected species in accordance with relevant legislative requirements and accepted industry practice. A copy of the Construction Code is included at Appendix B of this Planning Statement for information, but does not form part of this application.
The proposed development will contribute to biodiversity creation in accordance with policy 7.19 of the London Plan; Strategic Policy 2 of the Redbridge Core Strategy; and policy E2 of the Redbridge Borough-Wide Polices DPD.
6.8 Water Resources A Flood Risk and Drainage Statement (Document C161-MMD-T-XST-CR112_WS129- 50003) has been produced in support of this planning application. This document considers flood risk from overland flow (Pluvial flood risk), from rivers or watercourse (Fluvial flood risk), from groundwater (Groundwater flood risk), from flows within sewers (surface water collected in drains and sewers) and from any other source. The desktop review of data suggests that the areas subject to this planning application are at low risk of flooding from any of the aforementioned sources. In order to examine and comment upon flood risk within the planning application area it is necessary to consider any effects generated by the overall proposals for the western and eastern end of the existing Ilford Yard. In respect of the areas covered by TCPA application RED/11/8 the situation is as follows:
For the Car Park Proposals at the western end of Ilford Yard
Currently the entire existing western end of the yard is likely to drain to existing sewers, ballast or track drainage within or outside the yard area, including the area which is the subject of the above planning application The effects of the proposals on the drainage system arise from a potential increase in impermeable area within the western end of the yard. In the vicinity of the existing GAF Training Centre there is drainage works proposed that are outside of Crossrail limits. These include foul and surface water drainage located to the north of the existing GAF Training Centre running in an east-west direction; and surface water drainage is proposed to the south of the existing GAF Training Centre. Foul and surface connections are proposed to be made to the existing public sewers within Ley Street. This arrangement remains the same as proposed and approved in 1699/12.The western end of the yard will therefore continue to be drained to the public sewer in Ley Street. In order to mitigate the effects of any increase in impermeable area it is proposed to limit discharges to the public sewer to 7 l/sec (this has been accepted in principle by Thames Water). The attenuated flow to be released to the sewer approximates to green field flow for the area drained. The strategy is in accord with the principles set down in the National Planning Policy Framework. The approach provides a benefit by reducing peak flow from the site to the existing drainage system.

Town and Country Planning Act Application - Planning Statement RED/11/8 Document Number C161-MMD-T-XST-CR112_WS129-50010 Rev 3.0
For the proposals for a replacement GAF Training Centre at the eastern end of the Ilford Yard
The entire eastern end of the yard is understood to drain to the culvert crossing the site which currently passes beneath the existing GAF maintenance building and is proposed to remain beneath the proposed replacement GAF Training Centre. The replacement training Centre is anticipated to drain to the existing culvert as does the existing area. There is anticipated to be no change in effective impermeable area, roof will replace hardstanding. The only change may be a reduced time of concentration. It is anticipated that a small volume of attenuation (to be determined at detailed design stage) will be required to provide a small reduction in peak flow.
The proposed development is to be carried out, as all work relating to Crossrail, in accordance with the Crossrail Environmental Minimum Requirements (EMR) which incorporate, as Annex 1, the Construction Code. These documents form the incorporated mitigation for the proposed development and include procedures for site drainage, the protection of watercourses and control of pollution of groundwater. A copy of the Construction Code is included at Appendix B of this Planning Statement for information but does not form part of this application. At present unrestricted flows from the TCPA planning application area and other parts of the yard reach the existing drainage network but the detailed extent of that network is not yet known.
The mitigation measures (approved in 1699/12) comply with the principles contained within the NPPF, the attenuation storage measures and flow restrictions provided will improve the current situation by reducing peak flows discharged from the site to the wider drainage system. The proposed development is considered to be in accordance with the NPPF; policies 5.12, 5.13 and 7.13 of the London Plan; Strategic Policies 2 and 3 of the London Borough of Redbridge Core Strategy and policy E5 of the London Borough of Redbridge Borough-Wide Primary Policies DPD. Please refer to the accompanying Flood Risk and Drainage Statement for further information on the findings outlined above.
6.9 Contaminated Land and Waste Management The Land Contamination Statement (Document C161-MMD-T-XST-CR112-50001) that accompanies this Planning Application summarises the site history, details previous ground investigations and sets out the remediation strategy for the site. Based on the ground investigation results, remediation works are unlikely to be required. As with any site where there is history of industry there may be a risk from unknown contamination but the proposed use is one that is generally acceptable in this type of environment. The proposed development is to be carried out, as all work relating to Crossrail, in accordance with the Crossrail Environmental Minimum Requirements (EMR) which incorporate, as Annex 1, the Construction Code. These documents form the incorporated mitigation for the proposed development. The Construction Code requires an assessment of contaminated land under guidance contained within the Environmental Protection Act 1990 and the accompanying Contaminated Land (England) Regulations 2000; and mitigation measures will be developed in accordance with these regulations. The Construction Code also includes provisions relating to excavated material, waste Page 37 of 50 Document uncontrolled once printed.

management and recycling; and requires the nationally hierarchy for sustainable waste management to be used and a Site Waste Management Plan (SWMP) to be produced in accordance with the 2008 SWMP regulations. A copy of the Construction Code is included at Appendix B of this Planning Statement for information, but does not form part of this application.
6.10 Community Infrastructure Levy Based on 1438.44 m² of floor space netting off 251.6 m² (associated existing GAF training centre floorspace) gives a potential chargeable floor space figure of 1186.77 m².
6.11 Conclusions This planning application seeks approval for the provision of depot car parking on land that is outside of the Crossrail Act limits, the relocation of the GAF Training Centre and the co- located BUCF and works to improve sewer connections to Ley Street. The key issues for consideration in this application are providing justification for the parking requirement, the layout, siting and design of the proposed works and their impacts on visual amenity, water resources, biodiversity and trees. Various alternative locations were considered to ensure the most suitable location for the provision of car parking for the three train companies who will be operating from the Ilford yard complex. This planning application provides for the relocation of the existing GAF Training Centre to the east of the site. Parking will need to be made available on site for three railway companies, including for many staff working overlapping shift patterns, when full public transport is not operational.
The proposed development will not result in any adverse impacts on the Green Corridor or nature conservation area. New onsite and offsite planting is proposed to mitigate the loss of existing trees and shrubs. The planting will include trees (off-site) and the planting of shrubs (on-site) with some standard trees for immediate effect.
An application for 180 Ley Street for the demolition of the existing buildings and a permanent change of use from a builder’s yard to a staff car park associated was approved on the 27th February 2013 (Ref 2697/12). This permission will not now be implemented if this current application is approved. Neither the temporary use of the site, nor the permanent car park will impact on the surrounding area in any significant way. The location for car parking selected for this application is considered a less sensitive location than the site of the previous car parking application submitted (180 Ley Street) which was in close proximity to residential receptors.
It is also considered that the new GAF Training Centre and BUCF will not have any significant impact on the surrounding area, but would only be an extension to the existing Light Maintenance Depot building. The design of the extension will be in keeping with the existing building. There are no sensitive receptors nearby i.e. residential areas that would be affected by the proposal.
The proposed work is to be carried out, as all work relating to Crossrail, in accordance with the Crossrail Environmental Minimum Requirements (EMR) which incorporate, as Annex 1, the Crossrail Construction Code.
The proposed development is considered to accord with the relevant policies set out in

Section 5 and assessed in this Section 6 of this Statement, and in accordance with the provisions of the London Plan and the National Planning Policy Framework, which seek to ensure that development does not create unacceptable impacts, while at the same time facilitates growth and sustainable development. Section 38(6) of the Planning and Compulsory Purchase Act requires that all planning applications should be determined in accordance with the provisions of the development plan, unless material considerations indicate otherwise. Crossrail is one of the country’s key infrastructure projects. It will significantly increase the capacity of the rail network into and across London, and relieve congestion and overcrowding on the existing rail and underground networks to meet the substantial growth in demand for travel over the coming decades. The use of the site as a temporary works compound, and then as a permanent car park, is an essential element to facilitate the efficient construction and operation of Crossrail. This application is for essential components required to support the delivery of this nationally significant infrastructure project. In conclusion, the scheme accords with Development Plan policies, and given the national significance of the Crossrail project, of which this is a key element, the Council is requested to support the application and approve the application.

Appendix A – Design and Access Statement
Proposal
The proposal involves the following works:
Extension to the south west corner of the existing GAF Light Maintenance Depot shed with a replacement two storey GAF Training Centre building including the provision of a Backup Control Facility (BUCF) for Crossrail route operations;
2.1m high metal palisade fence around the boundary of the new GAF training centre and BUCF.
Demolition of existing buildings including the GAF Training Centre and adjacent modular building to the west of the depot; removal of earth bund and trees to south- east of existing GAF Training Centre;
Removal of existing steel container located to east of existing GAF Training Centre (as shown in Photograph 8);
Upon completion of worksite use, the worksites will either be restored or developed, for the new car parking provision or the new GAF Training Facility /BUCF. ; Provision of permanent hard-standing and associated surface water drainage including connections to existing sewers at Ley Street.
Existing hedge to the north of the area to remain with provision of soft landscaping onsite;
Provision of retaining walls;
Installation of steel lighting columns (10m high)
All other associated works. i) Use
The proposed use is incidental to the use of the wider Ilford Yard site by Crossrail and two other railway companies there. The Ilford Yard Stabling Project will provide facilities for Crossrail rolling stock along the north eastern section of the Crossrail network. The car parking is required to not only provide replacement provision for that lost elsewhere within the wider site as a result of the Project, but also for the new Crossrail train operating company.
The car park will be for use only by Depot staff, therefore will not be accessible to the general public. The temporary compound will be for servicing the construction of the Ilford Yard Stabling Project and to facilitate any other associated works. The new GAF Training Facility will be used for training purposes.
Page 40 of 50 Document uncontrolled once printed. All controlled documents are saved on the CRL Document System © Crossrail Limited Decal Template: CRL1-XRL-Z-ZTM-CR001-50018 Rev.1.0
Town and Country Planning Act Application - Planning Statement RED/11/8 Document Number C161-MMD-T-XST-CR112_WS129-50010 Rev 3.0
The BUCF will normally be unmanned, when occupied there would be 6 operatives. ii) Amount
There will be 52 standard car parking spaces. The car park will also provide provision of one designated disabled parking space (the latter is covered by the area within limits). The total area of the car park will be approximately 0.18 hectares. The BUCF will be located on the ground floor and will cover an area of 156.86 m². The GAF training centre ground floor area covers 560.13 m² (the total ground floor area is therefore 716.99 m²). The GAF training centre first floor is 721.45 m² (the total area of for GAF Training Centre therefore equals 1281.58 m²). The existing GAF Training Centre building floor area equals 251.6 m² (the increase in GAF training facility m² allocation equals 1030. m²). Therefore the extension to the GAF Light Maintenance Depot including the BUCF will overall cover a floor space area of 1438 m². iii) Layout and Scale
The proposed layout ensures the safe circulation of vehicles and pedestrians. The car parking spaces will be grouped in three lines each space comprising of standard area of 4.8m x 2.4m.The car park will allow for a HGV turning area, towards the east of the site near the Logistics and Stores Building (the turning area is not subject to this planning application as it is located within Crossrail limits). The extension to the GAF Light Maintenance Depot will be two storeys approximately 8m high, in line with the existing light maintenance building. iv) Appearance
The areas identified as hardstanding on the drawing T-DDA-CR112 SD007-1-40102 will be a combination of concrete slabs and bituminous surfacing. The retaining walls will have a concrete finish.
The extension to the GAF Light Maintenance Depot will include steel cladding finishes in keeping with the existing Light Maintenance depot. There will be signage for the Greater Anglia Training Facility illuminated on the front facade of the extension, so the new centre is easily identifiable, details will be provided under a separate application. Refer to drawing C161-MMD-S-DDC-CR112_SD007_Z-35503 for further details of the appearance of the new GAF Training Centre and BUCF. The paved area running around the perimeter of the building will have a bituminous finish. v) Landscaping
The proposals will result in the loss of some vegetation to the west of the existing GAF training centre and the earth bund including brambles, shrubs and tree groups. There is an individual tree in the southern part of the application site that will be lost as a result of the proposed development. An arboricultural survey has taken place and an Arboricultural Statement accompanies this planning application. The tree, a sycamore, is identified as a tree of moderate quality and value. The proposal involves new off-site planting to

Town and Country Planning Act Application - Planning Statement RED/11/8 Document Number C161-MMD-T-XST-CR112_WS129-50010 Rev 3.0
compensate for trees removed from the site. 6 no. sycamore trees planted at 12/14cm girth size. There will also be provision of new proposed shrub areas along the north and the south boundary of the site. The existing shrub areas towards the north and west boundaries of the site will remain to create a form of screening to the site. The existing planting around the GAF Training Centre includes mainly exotic species such as eleagnus, cotoneastor and buddleia; the trees are sycamore. The species proposed for the new planting will be selected to reinforce the local townscape character and to enhance biodiversity. Species will include: Crataegus monogyna (hawthorn), Corylus avellana (hazel), Viburnum opulus (guelder rose), Rosa arvensis (feld rose), Quercus robur (English oak), Acer campestre (field maple) and Fraxinus excelsior (ash).
Access Assessment
This section provides information on access as required by the Town and Country Planning (General Development) Procedure order 1995 and Circular 01/2006. The purpose of this section is to explain the access arrangements to and within the site.
Access to the new car park
Car parking will be accessed through the existing main entrance to the Ilford depot site off Ley Street. There is a footpath leading from the GAF Training Centre to a gate within the boundary fence, providing pedestrian access to Corkers Path, which runs parallel to the western Ilford depot site boundary. This existing access from Corkers Path will be used for staff only pedestrian access to the car park. This existing pedestrian access is currently a controlled access and will remain so during both the temporary and permanent use.
The proposal ensures there are safe access points for both vehicles and pedestrians, where both exits are separate. A new internal pedestrian route is proposed that runs parallel to the west and north boundary of the application site. There will be no changes to the existing site entrance or impacts to the flow of traffic along Ley Street.
The new car parking is additional to that already provided elsewhere in the main depot which already has disabled parking provision, motorbike and cycle parking facilities. DDA compliant spaces are also proposed adjacent to the Crossrail Operations and Welfare Building. The existing pedestrian exit onto Corkers Path will allow staff to exit the site car park safely (located along the western boundary of the site), while the existing vehicular entrance onto Ley Street will enable safe vehicular access arrangements to and from the site. Access will be controlled both in terms of vehicles entering and exiting the car park and staff on foot leaving and entering the car park. Access to the extension of the GAF Light Maintenance Depot
There is already an existing dedicated entrance for pedestrians which will be utilised at the east end of the site. This runs around the GAF Light Maintenance Depot and will be linked up to a new path that would run around the boundary of the extension to the building. The existing access will also be utilised for any services and deliveries.

Town and Country Planning Act Application - Planning Statement RED/11/8 Document Number C161-MMD-T-XST-CR112_WS129-50010 Rev 3.0
There are six car parking spaces allocated to the existing GAF Training Centre (It will be ensured that these six spaces are accommodated in the existing car park to the east of the site where the new GAF training facility is to be located).
Design Principles
The following principles have guided the use and design of the works:
Minimisation of impacts on the existing community in terms of traffic, noise, dust and visual impacts. Minimisation of impacts on the environment including impacts on ecology, and water resources. Safe spaces for all i.e. safe pedestrian routes, safe vehicle routes and circulation throughout the car park. Also through existing lighting and CCTV. The proposed lighting stations will be fixed to 10m high tilted poles around the boundary of the car park. Lighting column locations are shown on drawing C161- MMD-T-DDA-CR112 SD007-1-40102. The design details of lighting are shown on drawing C161-MMD-T-DDA-CR112_SD007_1-40106.

PAGE 4 OF 62 1 INTRODUCTION
1.1 GENERAL
1.1.1 Crossrail will provide a railway system from Maidenhead and Heathrow in the west through central London to Shenfield and Abbey Wood in the east. The project consists of new tunnels and stations on an east-west alignment under central London and the modification of existing National Rail infrastructure to the east and west of central London.
1.1.2 In order for the project to proceed it is expected that one or more nominated undertakers will be appointed to implement Crossrail. Subsequent references to the nominated undertaker will be deemed to cover one or more organisations in this role. The nominated undertaker will be responsible for ensuring that the relevant provisions of this Code are observed by bodies exercising its functions, including any of its contractors and sub-contractors.
1.1.3 The Secretary of State will require the nominated undertaker to adhere to the arrangements provided in the Environmental Minimum Requirements in designing and constructing the Crossrail Works. Accordingly, it is expected that the Secretary of State will take steps to ensure that any nominated undertaker complies with this Code and is responsible for ensuring that the relevant provisions of this Code are observed by bodies exercising its functions, including any of its contractors and sub-contractors. The following provisions of this Code should be read accordingly.
1.1.4 The Code forms part of the Environmental Minimum Requirements for the Crossrail Works. The Environmental Minimum Requirements cover a number of issues related to the design and construction of Crossrail and its environmental impacts.
1.1.5 “Construction” in the Code includes all site preparation (including site investigation and remediation, where appropriate), demolition, material delivery, excavated material disposal, waste removal and all related engineering and construction activities.
1.1.6 The nominated undertaker will hold discussions with local authorities and other statutory agencies in advance of submissions for approval.
1.1.7 Changes in industry standards will be regularly reviewed during the development of Crossrail and the principles of BS EN ISO14001 will be adopted for the management review of changing standards.
1.1.8 Unless a piece of legislation will be expressly or impliedly disapplied or modified by the Crossrail Act it will continue to apply as normal to the
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 5 OF 62 design and construction of Crossrail. For example, waste management licences or discharge consents will still be required.
1.1.9 Where necessary, generic construction mitigation measures identified within the Environmental Statement have been transferred into the Construction Code to ensure environmental impacts are controlled.

PAGE 6 OF 62 2 GENERAL PRINCIPLES
2.1 CONSTRUCTION STRATEGY
2.1.1 A construction strategy has been developed with the following objectives:
(a) to meet the requirements of all relevant statutory legislation, codes of practice and standards; (b) to limit adverse impacts upon local communities and the environment so far as reasonably practicable; (c) to carry out the planning and delivery of the project in the most cost effective manner; (d) to limit impacts on the operations of Network Rail, London Underground and other rail companies; (e) to implement a community liaison plan including a complaints help-line and an independently appointed Complaints Commissioner; (f) to remove, where reasonably practicable, excavated material by rail and water transport and import construction materials by rail; (g) to implement a green travel plan for construction workers; and (h) to co-operate with adjacent projects as far as practicable to reduce the combined impacts.
2.2 ENVIRONMENTAL PRINCIPLES
2.2.1 The nominated undertaker will develop and implement an environmental policy and an Environmental Management System (EMS) for the project.
2.2.2 The Secretary of State or the nominated undertaker (as relevant) will review environmental performance in the selection process for tenderers and will require tenderers for the main construction contracts to have an EMS which is consistent with the principles of BS EN ISO14001 before being included on tender lists.
2.3 HEALTH AND SAFETY PRINCIPLES
2.3.1 The nominated undertaker will be committed to ensuring the health, safety and welfare of its employees and people who may be affected by the conduct of its undertaking.
2.3.2 The nominated undertaker will establish appropriate industry standards for health and safety and will seek continuous improvement in safety performance, in accordance with the principles of HSG65 "Successful health and safety management", published by the Health & Safety Executive.
2.3.3 The nominated undertaker will ensure that adequate arrangements are in place for the discharge of its duties as client and designer under the Construction (Design & Management) Regulations 2007 (CDM). The nominated undertaker will assess the competence and resources for
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 7 OF 62 health and safety of organisations appointed as other dutyholders under CDM, and will monitor compliance with discharge of its own and others' CDM duties throughout the project.
2.3.4 The nominated undertaker will develop a health and safety management system in accordance with the principles of OHSAS 18001 "Occupational health and safety management systems". This system will include documentation defining the nominated undertaker's internal arrangements for managing health and safety on the project and the specific requirements for health and safety applying to all designers and contractors appointed to work on the project.
2.3.5 The nominated undertaker will require that all contractors, appointed to carry out design or construction work on the Crossrail project, produce a Health and Safety Plan, defining how their work and associated risks to health and safety will be managed.
2.3.6 The nominated undertaker's arrangements for health and safety will include a system for management of risks. This will require all hazards to be identified, and suitable and sufficient assessments made of the risk, followed by adoption of appropriate measures to eliminate the risk or to control the risk, so far as is reasonably practicable. Where risks to the public are involved, these will be reduced to as low as reasonably practicable, and will be managed in accordance with the guidance in HSG151 "Protecting the Public" published by the Health & Safety Executive.
2.3.7 The nominated undertaker will continuously monitor the work of contractors and will conduct a programme of audits and inspections to ensure compliance with the requirements of this Code and other project health and safety requirements.
2.4 ENVIRONMENTAL MANAGEMENT PLAN
2.4.1 This Code requires the production of a number of Environmental Management Plans (EMPs). These plans will set out how the project will deliver the environmental requirements and how environmental issues that arise are handled to ensure compliance with relevant legislation and regulations and in accordance with the nominated undertaker’s environmental policies. The EMPs will be discussed with relevant qualifying local planning authorities (or highway and traffic authorities for Traffic Management Plans) and in preparing the EMPs the nominated undertaker will take into account their observations.
2.4.2 The plans will define the approach to address all environmental issues. The plans will set out how the nominated undertaker intends to operate the construction and work sites and will set out the specific control measures necessary to deliver the requirements of the Code.
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 8 OF 62 2.4.3 The nominated undertaker will produce EMPs to cover the works authorised by the Crossrail Act and they will be appropriate to the scale and nature of work along the route of Crossrail. Where appropriate an EMP will be produced as a single document covering all of the environmental issues for a particular worksite or worksites and also, where appropriate, grouping a number of worksites together within a single EMP.
2.4.4 The range of issues which will be covered by the EMPs, as appropriate for the various locations/worksites, is as follows:
(a) area management plan, providing general details of implementation, including working hours, site layout and site appearance; (b) emergency plan, including pollution incident controls; (c) community liaison plan; (d) lorry and traffic management plans; (e) green travel plan; (f) noise and vibration management plan; (g) dust management plan; (h) lighting management plan; (i) site waste management plan; (j) ecological management plan; and (k) water management plan.
Health & safety plans will also be produced and they would be issued to the local authorities for information on request.
2.4.5 It is envisaged that some or all of the Environmental Management Plans may need to be updated, in consultation with any relevant qualifying authorities, as the detailed design of the works is developed.
2.4.6 In addition, the Environmental Memorandum identifies a number of environmentally sensitive sites. Environmental Management Plans for these sensitive sites will be produced in accordance with the provisions set out in that document.
2.5 SITE MANAGEMENT
General
2.5.1 It is expected that contractual arrangements will require all Crossrail contractors to provide suitably qualified staff to manage and execute works in which they are involved.
2.5.2 The nominated undertaker will require that all contractors have an appropriate awareness and working knowledge of the legislation, codes of practice and guidance relevant to the various construction activities. Contractors should have an awareness and working knowledge of
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 9 OF 62 environmental legislation relevant to the construction activities in which they are engaged.
Training and Competence
2.5.3 The nominated undertaker will require contractors to employ an appropriately qualified workforce, which may include holding a card from an appropriate recognised competence scheme, such as the Construction Skills Certification Scheme or the Personal Track Safety scheme for railways. The nominated undertaker will require Contractors to operate induction schemes for all personnel to ensure that they are aware of their individual responsibility to comply with the Code.
2.5.4 The Contractor will be responsible for identifying the training needs of his personnel to ensure that appropriate training is provided. The training will include “toolbox talks” for site operatives to maintain an appropriate level of awareness on health, safety, community relations and environmental topics and to advise employees of changing circumstances as work progresses. Records will be kept of attendance.
2.6 COMMUNITY RELATIONS
2.6.1 The nominated undertaker and contractors will be committed to providing community relations personnel, who will be focussed on engaging with the community to provide appropriate information and to be the first line of response to resolve issues of concern. The nominated undertaker will take reasonable steps to engage with residents of ethnic minority backgrounds and residents with disabilities (or other priority groups as appropriate), who may be differentially affected by construction impacts.
2.6.2 A Complaints Commissioner will be appointed for Crossrail. He will be employed by the Secretary of State on behalf of the High Level Forum. The High Level Forum will determine the precise terms of reference.
2.6.3 The nominated undertaker will ensure that occupiers of nearby properties will be informed in advance of works taking place, including the estimated duration. In the case of work required in response to an emergency, the LA and local residents shall be advised as soon as reasonably practicable that emergency work is taking place. Potentially affected occupiers will also be notified of the Helpline number, which will operate 24 hours per day, 7 days per week. One or more information centres will be provided at appropriate locations along the route.
2.6.4 The nominated undertaker will develop a Community Relations Strategy which will include the following responsibilities:
(a) monitor contractor and subcontractor compliance with undertakings and performance against commitments, local
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 10 OF 62 agreements and specific community requirements throughout the project; (b) maintain regular communication to ensure that the community and other stakeholders and affected parties are kept well informed. The contractors will be required to produce information sheets of the works to be carried out, detailing expected disruptions and the measures being taken to minimise or mitigate adverse impacts of these works, as far as reasonably practicable at least two weeks prior to construction activity taking place. A liaison plan will be issued in advance to local authorities detailing the information to be supplied; (c) as far as tunnel boring is concerned, the nominated undertaker will be required to establish a website that will provide information on the forecast and actual passage of the tunnel boring machines. In addition, the nominated undertaker will be required to distribute leaflets along the route of the tunnel drives giving notice of the forecast passage of the tunnel boring machines; (d) respond quickly to emergencies, complaints or other contacts made via the helpdesk or any other recognised means; (e) liaise closely with the emergency services, local authority officers and other agencies (based on established contacts) who may be involved in incidents or emergency situations; (f) liaise with appropriate local community projects, employment and educational initiatives; (g) ensure that a comprehensive community emergency plan is put in place for each section of the work. This will ensure that in the case of a major emergency, the community can be kept fully informed and will ensure that adequate arrangements are in place for the evacuation of an affected area if necessary; (h) provide a point of contact for a small claims procedure, relating to claims of physical damage to property, or minor injuries. The nominated undertaker would assist in enabling claims to be progressed promptly in liaison with an administrator appointed by them; and (i) co-ordinate the carrying out of pre-construction defect surveys in properties which have been identified as potentially being affected by tunnelling operations and other identified works. Liaise with the independent building surveyor employed to carry out the surveys to maintain a dialogue between the nominated undertaker and property owners throughout the duration of the works.
2.6.5 The nominated undertaker will contractually require all contractors to comply with the obligations to be placed on contractors under the Construction Community Relations Strategy Framework as finally formulated by the Promoter.
2.6.6 The nominated undertaker will maintain and advertise a telephone helpline staffed 24 hours per day to handle enquiries regarding construction activities from the general public. It will also act as a first
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 11 OF 62 point of contact and information in the case of any emergency. All calls will be logged, together with the responses given and the callers' concerns actioned and a response provided promptly. The helpline will be widely advertised and displayed on site signboards. It will also be possible to contact the helpline service via the Crossrail website. Statistical information on complaints would be sent to local authorities and the Planning Forum on a regular basis.
2.7 APPROVALS PROCESS
2.7.1 The Crossrail Act sets out the mechanism by which approval for specific consents relating to Crossrail will be obtained from the local planning authorities. The nominated undertaker will establish a project approval process to ensure that all appropriate approvals and clearances are obtained before a specific element of the works is started.
2.8 WORKS TO THE NATIONAL RAIL NETWORK
2.8.1 Access to the national rail network for maintenance, renewals and other construction activities is subject to a detailed regime (set out in the Network Code) which is administered by Network Rail. These restrictions of access are referred as possessions or, in the case with very long durations, blockades. Except in emergencies, these possessions and blockades must be planned and booked well in advance, and normally take place at times which limit disruption to railway users. Accordingly, these works usually take place at weekends, public holidays and overnight. Network Rail also has requirements regarding the manner in which works are carried out. Crossrail Works on the national rail network will be carried out in accordance with the detailed requirements of the Network Code (including working hours) which limit disruption. The environmental statement was completed on this basis.
2.8.2 Network Rail may decide to combine works required for Crossrail with their own enhancement, renewal and maintenance activities to use railway possessions and blockades efficiently.
For works being carried out at existing stations where no possession of the network is required, a separate access regime would apply (the Stations Code). It is possible that some of these can be carried out during core working hours provided that these do not prejudice ongoing safe operations and operational requirements.
2.8.3 Similarly, works undertaken in respect of utilities on the national rail network or at stations would be subject to the Network Rail’s normal processes as described above.

PAGE 13 OF 62 3 GENERAL SITE OPERATIONS
3.1 CONSTRUCTION PROCESS
3.1.1 The construction of Crossrail will extend across London and beyond and require works at about 100 work sites. Crossrail is a major construction project and will involve many different types of construction activities. These activities will include: demolition; site clearance; site investigation; remediation; tunnelling; piling; excavation; services diversion and new installations; bridge works; highway works; below ground and surface building works; new and alteration of railway track works; railway signalling, electrification and communication works; fit out; and provision of new trains and train maintenance facilities.
3.2 WORKING HOURS
3.2.1 The nominated undertaker will obtain consents from the relevant local authority under the Control of Pollution Act 1974, Section 61 (which will include noise limits and vibration limits where relevant) for the proposed construction works, as set out in section 5.1 below. The applications for consent will include details of the work to be undertaken, including proposed hours of work. All construction activities carried out on site, whether in core hours or on a 24 hour basis, will be agreed with the local authorities through the Section 61 process. All of the arrangements for working hours may be varied by agreement with the relevant local authority. The right to appeal against a withholding of consent or against conditions subject to which it is given is retained, and references to agreement are to be so construed.
3.2.2 Core working hours will be from 0800 to 1800 on weekdays and 0800 to 1300 on Saturday. Only non-disturbing preparatory work, repairs or maintenance will normally be carried out on Saturday afternoons or Sundays between 0900 and 1700. The nominated undertaker will adhere to these core working hours for each site as far as reasonably practicable and where feasible, operations anticipated to cause disturbance would be limited to these hours. Except in the case of emergency, any work required to be undertaken on a Sunday on sites without 24 hour activity will be agreed with the local authority in advance. There are certain exceptions to the core working hours, which are described below.
3.2.3 In order to maintain the above working hours, the nominated undertaker will require a period of up to one hour before and up to one hour after core working hours for start up and close down of activities. The activities to be undertaken during this period may include: deliveries to and from site; loading; unloading; arrival and departure of workforce and staff at site and movement to and from place of work; general refuelling; site inspections and safety checks prior to commencing work; site meetings; site clean up; site maintenance; and maintenance and checking
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 14 OF 62 of plant and machinery, but not including operation of plant or machinery giving rise to noise likely to exceed the noise trigger levels for the periods either side of the agreed core working hours as set out in the Crossrail Noise and Vibration Mitigation Scheme. The start up and close down periods are not to be considered an extension of core working hours, and particular care will be taken to limit and control disturbance to local residents during such periods. The nominated undertaker will, as far as reasonably practicable, arrange for deliveries in the start up period to take place close to the end of that period and in the close down period close to the start of that period.
3.2.4 All construction related traffic serving the Crossrail work sites will abide by the agreed hours of working for each specific location. These hours will cover the timing of deliveries, off-loading and loading from the public highway. Deliveries, other than abnormal loads, will not take place outside the core working hours and the start up and close down periods without the prior agreement of the local authority, specifically through the Environment Health Department, or as otherwise advised by the local authority. Vehicles awaiting loading or offloading will not leave engines running when not directly in use unless prior agreement has been sought.
3.2.5 From sites where works are not undertaken on a 24 hour basis, excavated material will only be removed by road during core working hours.
3.2.6 The following activities will normally be undertaken on a 24 hour per day, 7 day per week basis:
a) tunnelling works together with directly associated activities (such as maintenance of tunnelling equipment, construction of cross passages and installation of tunnel linings); b) delivery of materials, consumables and plant to the tunnel face from the drive portal or access shaft and for tunnel fit out by train from tunnel logistics sites at Aldersbrook and Old Oak Common. c) transportation, storage and removal of excavated material by conveyor, barge and rail; d) track laying and internal fit out works within the stations, shafts and tunnels (including construction of the track bed and cable laying). e) operation and maintenance of items of plant and equipment needed in order to safeguard and support the works, such as fans, compressors, generators and batching plant. Any such equipment will be shielded in order to provide appropriate noise attenuation (this is covered further in section 5.3); f) Staff may also be required to collect data and samples outside normal working hours; and g) surface support to the underground work, including welfare facilities, cranage, workshops and stores.
3.2.7 Where the nominated undertaker can demonstrate that overall progress would be significantly affected by not being able to remove excavated CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 15 OF 62 material outside of the core working hours, then additional hours for the removal of excavated material would be agreed with the local authority. The nominated undertaker would expect the agreement of the local authority not to be unreasonably withheld.
3.2.8 In order to safeguard the works it may be necessary for certain items of plant and equipment to be kept running 24 hours per day, which would include pumps and generators. Any such equipment will be shielded in order to provide appropriate noise attenuation. Staff may be required to collect data and samples outside core working hours at times.
3.2.9 Certain works requiring temporary possession of roads and railways for safety or operational requirements, to limit disruption to road and railway users and the travelling public, and works in connection with utilities when demand is low will need to be undertaken outside core working hours. This will include Saturday afternoon, night-time, Sunday and/or bank holiday working from time to time. On occasion longer term possessions (in excess of one week) will be required for more major works.
3.2.10 In the case of work required in response to an emergency or which if not completed would be unsafe or harmful to the permanent works, the relevant local authority will be informed as soon as reasonably practicable of the reasons for, and likely duration of, the works. The local authority will provide a telephone number and nominate an office to receive such notification, which will be reviewed regularly. Examples of the type of work envisaged would include where pouring concrete takes longer than planned due to equipment failure or where unexpected poor ground conditions, encountered whist excavating, require immediate stabilisation.
3.2.11 Where work has to be rescheduled for reasons not envisaged and is expected to extend beyond the agreed or core working hours or exceed the agreed limits and dispensation to the Section 61 consent, the nominated undertaker will apply for a variation to the section 61 consent to the relevant local authority at least 14 days in advance of the start of those works.
3.2.12 Where rescheduling relates to work of a critical nature for reasons not envisaged and beyond the control of the nominated undertaker (such as key activities likely to delay other key activities) applications will be made where practicable at least 48 hours in advance and at least 7 days in advance if the work is expected to last for a period of 5 days or more. The variation will be sought by means of an application setting out the revised construction programme or method and the relevant noise calculations.
3.2.13 Where such working outside core hours has been discussed and accepted (as in 3.2.12 above) nearby occupiers who are likely to be affected by the
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 16 OF 62 works will be informed as soon as reasonably practicable by the nominated undertaker about the nature and likely duration of the works.
3.2.14 Deliveries will be arranged to minimise impacts on the road system so far as reasonably practicable. Abnormal and special loads may be delivered outside core working hours subject to the requirements and approval of the relevant authorities.
3.2.15 Where reference is made above to seeking local authority agreement then an application will be made under the Control of Pollution Act 1974, Section 61, as detailed in 3.2.1 above.
3.2.16 In relation to works on the national rail network and existing stations, please also refer to section 2.7.
3.3 SITE LAYOUT AND FACILITIES
3.3.1 The nominated undertaker will ensure, as far as reasonably practicable and appropriate, that the site layout and appearance will be designed using the following principles:
(a) sites at prominent locations will be screened; (b) all sites will be fully secured; (c) existing features will screen the sites where appropriate; (d) storage sites, fixed plant and machinery equipment and temporary offices will be located to limit environmental impacts, as far as reasonably practicable, and having due regard to neighbouring accommodation, as far as allowed by the constraints of each site; (e) site lighting will be located and directed so as not to intrude into occupied residential properties, on sensitive areas or constitute a road or rail hazard; (f) security cameras will be sited and directed so that they do not intrude into occupied residential properties; and (g) site plant and facilities will be powered from mains electrical sources.
3.3.2 The nominated undertaker will ensure, as far as reasonably practicable, that the visual intrusion of construction sites on nearby residents and users of local facilities and amenities is contained and limited. The nominated undertaker will ensure that, where appropriate, construction activities will be screened to protect nature conservation sites and the amenity value of recreational facilities.
3.3.3 The nominated undertaker will display a contact name, telephone number and address, and the Helpline number at appropriate locations on the boundaries of the sites.
3.3.4 The type of hoarding or fencing used will vary from location to location but will accord with the following principles:
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 17 OF 62 (a) the standard hoarding will be 2.4 m minimum height, plywood faced, timber framed hoarding suitably painted; (b) the hoarding will be increased in height and possibly altered in form to enhance acoustic performance for specific locations ; (c) a 1.8 m high chainlink fencing may be used at more remote locations; (d) suitable measures will be used for tree protection (see Chapter 10); (e) where reasonably practicable existing walls, fences, hedges and earth banks will be retained; (f) notices will be displayed on all site boundaries, where appropriate, to warn of hazards on site such as deep excavations, construction access, etc; (g) appropriate sight lines/visibility splays will be maintained to ensure safety of both vehicles and pedestrians is preserved; and (h) temporary fences may be used in certain areas, such as for short term occupation of sites or at more remote locations.
3.3.5 The extent and height of hoarding or fencing at a particular location will be selected to maintain effective security and achieve appropriate noise attenuation and visual screening.
3.3.6 Hoarding will be painted and may include a Crossrail Logo and/or that of the nominated undertaker. Hoarding will be maintained in good condition.
3.3.7 All vehicle access and egress points will have gates positioned such that no gate will be permitted to open out onto the highway. As far as reasonably practicable, gates will be located to allow vehicles to drive clear of any public highway. Where provided for noise control, gates will be of a similar material and construction to the boundary in which they are situated and will be closed except when being used for access.
3.3.8 The nominated undertaker will promote and enforce a “good housekeeping” policy on all the construction sites to ensure that clean, tidy and safe sites are provided. Arrangements will be implemented to provide effective preventative pest control and prompt treatment of any pest infestation.
3.3.9 The nominated undertaker will ensure that appropriate welfare facilities are provided at all major sites. The facilities will include canteens, toilets, showers, locker rooms and first aid posts. The facilities will be connected to mains services and drainage, where reasonably practicable.
3.4 SITE LIGHTING
3.4.1 Site lighting and signage will be provided to ensure the safety and security of the construction sites and will be at the minimum luminosity necessary.

PAGE 34 OF 62 1973, has an appropriate permit issued and is maintained according to the procedures set out in the Pollution, Prevention and Control Act 1999; (cc) ensure that any plant, identified above, is operated in accordance with the conditions set out in the permit and a copy of the permit is held on site; (dd) use enclosed rubble chutes and conveyors where reasonably practicable or use water to suppress dust emissions from such equipment; (ee) always use enclosed conveyors where crossing roads, other public areas and property which is not in the ownership or control of the nominated undertaker; (ff) sheet or otherwise enclose loaded bins and skips; (gg) minimise drop heights from conveyors, loading shovels, hoppers and other loading or handling equipment and use fine water sprays on such equipment wherever appropriate; (hh) seal or re-vegetate completed earthworks as soon as reasonably practicable after completion; (ii) use design/prefabrication to reduce the need for grinding, sawing and cutting on site wherever reasonably practicable; (jj) only use cutting, grinding or sawing equipment fitted or in conjunction with suitable dust suppression techniques such as water sprays or local extraction; (kk) carry out site inspections regularly to monitor compliance with dust control procedures set out above and record the results of the inspections, including nil returns, in the log book detailed; (ll) increase the frequency of site inspections when activities with a high potential to produce dust are being carried out and during prolonged dry or windy conditions; and (mm) record any exceptional incidents causing dust episodes on or off the site and the action taken to resolve the situation in the log book detailed in above.
Enhanced Dust Control Procedures on Sites with a Medium or High Risk of Dust Emissions (Tier 2)
6.3.6 Where a site has been identified as having a medium or high risk of emissions of dust due to the proximity of receptors, the type of activity on site or the duration of operations, a higher standard of dust control will be required. The dust control procedures adopted for Tier 2 will include the appropriate controls listed under Tier 1 in addition to those set out below for Tier 2. Alternatives may be proposed to suit specific circumstance providing the resulting control is at least as effective as that arrived at using the specified measures.
6.3.7 The enhanced dust control procedures, Tier 2, will include, as appropriate, site controls to:
(a) strip insides of buildings, as far as reasonably practicable, before demolition;
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 35 OF 62 (b) bag and remove biological debris (such as birds nests and droppings) or damp down such material prior to demolition; (c) wherever reasonably practicable, retain walls and windows while the rest of the building is demolished to provide a screen against dust; (d) screen buildings, where dust producing activities are taking place, with debris screens or sheeting; (e) avoid carrying out earthworks during dry weather if reasonably practicable having regard to programme and contracting arrangements for the relevant works or provide and ensure appropriate use of water sprays to control dust; (f) seed or seal medium or long term excavated material and soil stockpiles; (g) ensure slopes on stockpiles are no steeper than the natural angle of repose of the material and maintain a smooth profile; (h) ensure equipment is readily available on site to clean any spillages and clean up spillages as soon as reasonably practicable after the event using wet cleaning methods; (i) ensure mixing of cement, bentonite, grout and other similar materials takes place in enclosed areas remote from site boundaries and potential receptors; (j) where appropriate use increased hoarding height to protect receptors; and (k) consider full enclosure of sites or specific operations where there is a high potential for dust production and the site is active for an extensive period.
Advanced Dust Control Procedures on Sites with a High Risk of Dust Emissions (Tier 3)
6.3.8 Where a site has been identified as having a high risk of dust emissions due to the proximity of receptors, the type of activity on site or the duration of operations, the highest standard of dust control reasonably achievable will be adopted. In these cases all the techniques set out above will be employed and will include additional measures to control the high risk. This will include having personnel on site to monitor and manage dust emissions. Techniques such as total enclosure of certain operations to protect vulnerable receptors would be implemented where appropriate. The measures will be proportionate to the risk and will be site specific.
Dust Monitoring Strategy
6.3.9 The nominated undertaker will ensure that where appropriate dust monitoring will be carried out on Crossrail construction sites, during construction, at medium and high-risk sites. A risk-based approach will be used to identify the type of dust monitoring to be used at each worksite by looking at the details of the specific packages of work within the site boundaries. The assessment will look at the dust raising potential of construction activities (as defined in Table 2-4, Volume 1, Crossrail
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 36 OF 62 Assessment of Atmospheric Emissions and Air Quality Impacts; Technical Report), proximity to potential receptors and the duration of construction activities at each location.
6.3.10 Where sites have a risk score that assigns them to the low risk category no dust monitoring will be carried out. Where sites have a risk score that is in the medium risk category passive deposition monitoring techniques (glass slides/Frisbee gauges / sticky pads) will be adopted at appropriate locations (site boundaries/local receptors) according to specific site conditions.
6.3.11 At high risk sites a baseline will be established prior to construction. This will be determined, where reasonably practicable, for a twelve month
period derived from data sourced from local background PM10 concentrations measured by the Automatic Urban and Rural Network (AURN) monitoring sites and appropriate local authority automatic monitoring sites. By establishing a baseline the nominated undertaker will ensure, as far as reasonably practicable, that:
(a) Monitoring data will be readily available for appropriate periods prior to construction. -3 (b) Data will be collected as PM10 µg.m , the same units as is suggested for the site action level in the London BPG. (c) Localised unidentified sources creating a false baseline are avoided (eg local construction activity: local monitoring site operators should note any unusual activity in the vicinity of monitoring sites that may affect monitoring results).
6.3.12 The nominated undertaker will require contractors to begin dust monitoring as soon as reasonably practicable after obtaining possession of high risk sites in order to provide localised data to augment the data obtained from the AURN/Local Authority sites.
6.3.13 During construction particulate monitoring will be undertaken using appropriate survey instruments such as Osiris, Topaz, DustScan or similar devices. Two instruments will be deployed at each high risk site and will be sited at locations such as site boundaries, potential receptors or in a transect orientated to the prevailing wind, as appropriate to specific site characteristics.
6.3.14 Instruments will be set-up at high risk sites to operate an alarm (PC based or mobile phone) when a predetermined site action level is reached. If the alarm is triggered the following actions will be taken:
(a) The nominated person or someone delegated by the nominated person will as quickly as reasonably practicable investigate activities on the site to ascertain if any visible dust is emanating from the site or activities are occurring that are not in line with dust control procedures.
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 37 OF 62 (b) Any identified causes will be rectified where practicable. Actions will be recorded in the site logbook and the relevant local authority notified of the incident and actions by telephone or e-mail as soon as practicable after or during the incident. (c) If no source of the incident is identified other Crossrail sites and local authority or AURN monitoring sites will be contacted to establish if there is a wider area increase in particulate concentrations. (d) If the cause of the alarm is not related to site operations the outcome of any investigation will be recorded in the site logbook and reported to the relevant local authority at an appropriate time.
6.3.15 At high risk sites, a site action level will be established by reference to
local authority and AURN PM10 monitoring data in consultation with the relevant local authority. Subject to consultation, a preliminary site action level of 250µg.m-3 (15 minute average) will be adopted.
6.3.16 Dust monitoring will be continued at a medium or high-risk site until the site has a risk score that assigns it to the low risk category. The cessation of monitoring when a site no longer represents a high or medium risk is subject to consultation with and the agreement of the local authority in whose area the worksite is situated that high or medium risk no longer applies, provided that such agreement is not unreasonably withheld, and the local authority is a qualifying authority for the purposes of Schedule 7 to the Crossrail Bill.
6.4 ASBESTOS
6.4.1 A management system will be established, which will adopt measures complying with the Regulations and Code of Practices, to manage the risk from release of asbestos during alteration and demolition works and excavation work. This system will ensure compliance with the Control of Asbestos at Work Regulations 2002 (SI/2002/2675) and associated Approved Codes of Practice, and will provide for inspection, survey sampling and analysis in accordance with HSE guidance MDHS100 “Surveying, sampling and assessment of asbestos-containing materials”.
6.4.2 Measures for managing asbestos in alteration, demolition and excavation works will include:
(a) employing competent contractors to carry out alteration and demolition works; (b) contractors implementing a procedure for dealing with potentially suspect materials exposed requiring sampling and analysis by an independent specialist consultant; (c) formal exchange of information before start of work, including relevant information from the Asbestos Register to clearly identify location of asbestos-containing materials; and (d) method statements for any works in the vicinity of asbestos- containing materials to avoid any disturbance to such materials which are not to be removed.
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 38 OF 62
6.4.3 Measures for managing work involving asbestos-containing materials encountered in construction will include:
(a) appointment of a specialist consultant independent of the asbestos treatment contractor; (b) ensuring any work with asbestos-containing materials is notified to the Health & Safety Executive; (c) ensuring any work with asbestos-containing materials is carried out by licensed specialist asbestos treatment contractors in accordance with Asbestos ( Licensing ) Regulations 1983 ( SI 1983/1649 ) as amended in 1998 ( SI 1998/3233); (d) requiring method statement defining detailed control measures to be produced by the specialist asbestos treatment contractor and approved by the independent specialist consultant; (e) air sample monitoring by the independent specialist consultant of work to ensure required air quality standards are achieved; and (f) disposal of asbestos-containing materials to licensed waste sites in accordance with Special Wastes Regulations 1996 (SI 1976/972).
6.5 ODOUR
6.5.1 The nominated undertaker will adopt appropriate measures so as to avoid the creation of statutory nuisance from odours.

7.1 GENERAL
7.1.1 The nominated undertaker will undertake the works and implement working methods which will be developed to protect surface and groundwater from pollution and other adverse impacts including change to flow volume, water levels and quality. This will be completed in accordance with relevant legislative requirements and appropriate industry guidance.
7.1.2 The Crossrail Act sets out protective provisions for the Environment Agency, under which the nominated undertaker will be required to obtain Agency approval for works, which would be likely to affect any surface or groundwater resource. The nominated undertaker will prepare a strategy for handling water resources issues in consultation with the Environment Agency (EA) and will be based on accepted industry practice. The process for agreeing the strategy will include liaison and consultation with key stakeholders.
7.1.3 Water Management Plans will be produced by the nominated undertaker for each of the construction sites including water courses, and will take account of the guidance contained within the relevant Pollution Prevention Guides issued by the EA and other Construction Industry Research and Information Association (CIRIA) documents. Specific receptors in the water environment will be listed in the plans. Where appropriate, integrated aquatic ecology and water quality plans will be developed.
7.1.4 Contingency plans to deal with major pollution incidents at the work sites will be included within the overall emergency planning. EA guidance on pollution incident response planning will be reflected in the emergency plans.
7.2 PROCEDURES
Site Drainage
7.2.1 Site drainage, including surface runoff and dewatering effluents, will be discharged to sewers where reasonably practicable and relevant permissions will be obtained from the sewerage or statutory undertaker. Discharge to watercourses will only be permitted where discharge consent or other relevant approval has been obtained.
7.2.2 The nominated undertaker will ensure that the site drainage meets the effluent and flood risk standards required by the sewerage undertaker or EA as appropriate in accordance with the relevant discharge consent or the protective provisions in the Crossrail Act, and will provide and
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 41 OF 62 maintain holding or settling tanks, separators and other measures as may be required. The nominated undertaker will ensure that access is provided to the undertaker so that samples of discharge can be obtained and analysed and the flows verified as required.
7.2.3 The relevant sections of BS6031: Code of Practice for Earthworks for the general control of site drainage will be followed.
7.3 PROTECTION OF WATERCOURSES
7.3.1 The nominated undertaker will seek to control flood risk to appropriate levels set by the Environment Agency, using mitigation, compensation and/or monitoring where required. Approval will be obtained in advance for all crossings of, diversions to, and work affecting watercourses from the EA as set out in the protective provisions.
7.3.2 Protection measures for works in or adjacent to watercourses will be provided in accordance with appropriate requirements.
7.3.3 Watercourses, including land and/or road drainage, within the construction sites will be maintained to provide effective working conditions at all times.
7.3.4 All reasonably practicable measures will be taken to prevent the deposition of silt or other material in, and the pollution by sediment of, any existing watercourse, canal, lake, reservoir, borehole, aquifer or catchment area, arising from work operations. The measures will accord with the principles set out in industry guidelines including as the EA’s note ‘PPG05: Works in near or liable to affect water courses’ and CIRIA’s report ‘C532: Control of water pollution from construction sites’. Measures may include use and maintenance of temporary lagoons, tanks, bunds and silt fences or silt screens as well as consideration of the type of plant used and the time of the year for working in watercourses.
7.3.5 Other than in water bodies where the Port of London Authority guidelines will be applied, sediment plumes from dredging in inland waterways, including those under control of British Waterways, will be controlled by measures in accordance with the principles set out in industry guidelines such as the CIRIA’s Report 169 ‘Inland Dredging – guidance on good practice’ and Section 6 of CIRIA’s Report C547 ‘Scoping the assessment of sediment plumes from dredging’. Contaminated dredged material will be managed as described for other contaminated land materials.
7.4 CONTROL OF POLLUTION OF SURFACE WATER
7.4.1 The nominated undertaker will ensure that protection measures to control the risk of pollution to surface water will be adopted and will include, where appropriate and reasonably practicable:
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 42 OF 62 (a) any containers of contaminating substances on site will be leakproof and kept in a safe and secure building or compound from which they cannot leak, spill or be open to vandalism. The containers will be protected by temporary impermeable bunds with a capacity of 110% of the maximum stored volume. Areas for transfer of contaminating substances will be similarly protected; (b) all refuelling, oiling and greasing will take place above drip trays or on an impermeable surface which provides protection to underground strata and watercourses and away from drains as far as reasonably practicable. Vehicles will not be left unattended during refuelling; (c) only construction equipment and vehicles free of oil/fuel leaks which could cause material contamination will be permitted on site. Drip trays will be placed below static mechanical plant; (d) all wash down of vehicles and equipment will take place in designated areas and washwater will be prevented from passing untreated into watercourses and will comply with EA’s Pollution Prevention Guidance (PPG)note PPG13; (e) EA note PPG 23 will be followed when carrying out maintenance of structures over water. As far as reasonably practicable, only biodegradable hydraulic oils will be used in equipment working in or over watercourses; and (f) appropriate measures to be taken to protect erodable earthwork surfaces.
7.5 CONTROL OF POLLUTION OF GROUNDWATER
7.5.1 The nominated undertaker will ensure that protection measures to control the risk of pollution to groundwater will be included within the overall strategy; these will in particular be consistent with the Groundwater Regulations 1998.
7.5.2 Where reasonably practicable, the nominated undertaker will avoid using materials in the permanent or temporary works that could pollute groundwater, this will include special consideration for the use of substances contained within List I and II of the Groundwater Regulations SI 1998/2746 (Groundwater Directive: 80/68/EEC).
Hygiene Requirements to Protect Groundwater
7.5.3 Personnel employed on hand excavation work of aquifer materials within a zone designated as an Inner Source Protection Zone or 50 Day Time of Travel Zone will be required to undergo prestart and ongoing health screening. Inductions for these personnel will include the need for personal hygiene and the dangers of contamination to groundwater.
7.6 MITIGATION OF IMPACTS AT ABSTRACTION BOREHOLES
7.6.1 The foregoing sections describe the measures used to minimise the risk of groundwater pollution. However at any particular abstraction, there will
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 43 OF 62 be a residual risk that the water quality may become unusable by an abstractor. The following precautionary actions will be applied, where applicable and reasonably practicable, to limit and manage the residual risks:
(a) where agreed by the nominated undertaker and well owners, some routine water quality monitoring may be undertaken at abstraction sources. The period of monitoring will be appropriate to the timing and type of work undertaken. The need for intermediate monitoring holes and procedures for water and contaminant testing during construction and operation will be discussed with the owners; (b) the nominated undertaker will arrange any necessary monitoring of water levels in areas where dewatering of the deep aquifer is planned; and (c) where the water quality monitoring shows an adverse impact on water quality, then the nominated undertaker will contact the relevant abstractor as soon as practicable and the nominated undertaker will, as far as reasonably practicable, put in place appropriate emergency measures to overcome the adverse impact, where this adverse impact has resulted form the Crossrail works.
The nominated undertaker will so far as reasonably practicable recognise the rights of existing abstractors, and will consult them on measures to avoid or minimise loss or interruption of supply or provision of alternative supplies, so far as such measures or provision are reasonably practicable. The EA will also be consulted through the water resources strategy and will have an approval mechanism through the provisions in the Act.
7.7 DEWATERING
7.7.1 The foregoing provisions will also apply to dewatering, in addition to the following:
(a) records of water pumped will be kept at all major dewatering sites where wells are constructed in the deep aquifer or where required under the terms of a discharge consent; and (b) water quality at all major dewatering sites will be monitored weekly for the first 4 weeks of pumping and monthly thereafter. Monitoring will comprise a laboratory test of major ions and a field test of temperature and electrical conductivity as well as other parameters required under the conditions of a discharge consent or under the protective provisions.
7.7.2 Monitoring arrangements for dewatering will be developed in liaison with the Environment Agency, through the water resources strategy referred to in paragraph 7.1.2 above.
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 44 OF 62 7.7.3 Any site specific monitoring arrangements outside of limits will be dealt with by consent with relevant parties.
7.8 MONITORING AND MITIGATION OF WATER LEVELS IN THE SHALLOW AQUIFER
7.8.1 Additional site investigation (SI) will take place and some SI boreholes will be converted to standpipes where significant changes in water levels in the shallow aquifer are expected as a result of temporary dewatering or construction of major structures which cut off the shallow aquifer and could cause water levels to rise. Selected water levels will be monitored for a maximum of twelve months after dewatering or construction of the cut off is completed. The monitoring data will be analysed in relation to data on elevations of nearby basements and existing drains. Additional drainage will be provided as mitigation where necessary.
7.9 DREDGING
7.9.1 The nominated undertaker will follow Port of London Authority guidance for dredging in the tidal Thames and its tributaries. So far as is practicable, the critical period of June to August for dredging will be avoided. This will be achieved through programming capital dredging outside this period, and implementing a monitoring program to identify future maintenance dredging. Where practicable, the nominated undertaker will undertake a single maintenance dredge prior to the critical period.
7.9.2 The nominated undertaker reserves the right to undertake emergency dredging within the critical period of June to August should there be a requirement to do so. Dredging in response to an unforeseen event or occurrence which could not be reasonably expected or planned and which jeopardises the operation of the barge loading facilities constitutes an emergency.
7.9.3 So far as is practicable, to assist with minimising water quality and aquatic ecology impacts, the nominated undertaker will undertake capital and maintenance dredging using techniques that limit the dispersal of inter-tidal sediments.

PAGE 46 OF 62 8 CONTAMINATED LAND
8.1 INTRODUCTION
8.1.1 The nominated undertaker will assess contaminated land under guidance contained within the Environmental Protection Act 1990 (Part IIA). This guidance, referred to as the Part IIA regime, came into force in England in April 2000 by enactment of Section 57 of the Environment Act 1995. The accompanying Contaminated Land (England) Regulations 2000 (SI 2000/227) state the conditions under which land is defined as contaminated. The nominated undertaker will develop mitigation measures in accordance with these regulations.
8.1.2 The main objective of Part IIA is to provide a system for the identification of land where contamination is causing unacceptable risks to human health or the wider environment, with respect to the current use and setting of the land. If contaminated land is identified, the guidance contained within Part IIA is intended to ensure that where it is reasonable to do so, mitigation is carried out so that the land no longer presents an unacceptable risk.
8.2 SITE ASSESSMENT AND REMEDIAL PRACTICE
8.2.1 The nominated undertaker will carry out site assessments, investigations and/or risk assessments wherever construction work is planned in order to assess the potential for contamination in both soil and groundwater in accordance with standard industry guidelines such as CLR11. Any necessary measures will be agreed with the Environment Agency and local authorities as part of the construction planning process in accordance with relevant legislation.
8.2.2 A set of criteria for site investigation will be developed prior to the commencement of any intrusive works. Where site investigation reveals the presence of contamination an appropriate remedial strategy will be developed to identify the most appropriate option for dealing with the presence of contamination. This strategy would include the following:
(a) the nominated undertaker will liaise with the local authority, the Environment Agency and other relevant statutory bodies with a view to addressing their requirements and will agree control or protection measures necessary to provide appropriate mitigation. This may involve the sealing, excavation and disposal of soil or on- site remedial works; (b) the Consolidated European Waste Catalogue (EWC) lists those wastes that are ‘absolute entries’ (hazardous waste regardless of their concentration) and ‘mirror entries’ (hazardous waste only if ‘dangerous substances’ are present above threshold concentrations). Contaminated soils are ‘mirror entries’ in the EWC. This means that contaminated soils may be classified as either hazardous or non-
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 47 OF 62 hazardous depending on the concentrations of ‘dangerous substances’ in the soil. An assessment of the composition of the waste soil using appropriate techniques, which could include sampling and laboratory analysis, will be undertaken to determine if the waste is classifiable as hazardous; (c) the nominated undertaker will also give consideration to alternatives to landfill disposal as the solution to treating contaminated soil. This may include the use of remedial technologies (in-situ and ex-situ) to reduce the quantity of soil requiring disposal, and/or treatment of soils to a standard such that they can be re-used at a site or be disposed of as non-hazardous waste. On-site remedial works will be carried out under the Waste Management Licensing Regulations 1994; (d) contamination issues will be recorded in the project Health and Safety Plan in accordance with the Construction (Design and Management) Regulations 2007, to protect affected parties; (e) monitoring of excavation works will be undertaken to check for unexpected or unusual materials with a contaminative potential. This material could consist of buried drums, tanks or containers, soil, groundwater or liquids with an unusual colour or odour, or other evidence of contamination. If this type of material is encountered work will be stopped until the material has been properly identified and suitable precautions taken including amending risk assessments and the remedial strategy if appropriate. This approach will be included in the Health and Safety Plan; (f) the nominated undertaker will undertake specific precautions if materials containing asbestos are present or encountered during works, in order to comply with the Control of Asbestos at Work Regulations 1987 and Asbestos (Licensing) Regulations 1983 and their amendments, and adhering to relevant guidance including Asbestos: Exposure Limits and Measurement of Airborne Dust Concentrations (EH10 and MDHS 39/4) and Managing Asbestos in Workplace Buildings 1988; (g) the nominated undertaker will ensure that there are designated areas on site where contaminated materials can be separated from clean ones and stored in an appropriate environment. Storage of contaminated materials may require specific facilities to prevent contaminants from leaching into the ground, nearby watercourses or neighbouring properties; (h) guidance provided in the Environment Agency’s Pollution Prevention Guidance Notes (PPG’s) in respect of water pollution in particular PPG01, PPG02, PPG05, PPG06, PPG21 and PPG23 will be followed as far as reasonably practicable. Further guidance is provided in Planning Policy Statement 23: Planning and Pollution Control and Defra/Environment Agency’s Model Procedures for the Management of Contamination (CLR11);
(i) provision of a watching brief by an appropriately qualified person, where appropriate; and
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 48 OF 62 (j) on completion of any remedial works, a record will be kept of the works undertaken to comply with the remedial strategy. A verification report will be issued to the EA and the local authority.

9.1.1 The nominated undertaker will manage the excavated materials and demolition/construction wastes generated at worksites, so far as reasonably practicable, in accordance with the waste hierarchy and within the relevant regulatory controls and cost restraints under the general protocols described below.
9.1.2 The nominated undertaker will ensure that the management of excavated materials and waste will be in accordance with the waste hierarchy as detailed below.
9.1.3 The nominated undertaker will ensure that the requirements of the waste hierarchy are enforced and the duty of care placed on all parties to take responsibility for protecting the interests and safety of others from the potential impacts of handling, storing, transporting and depositing of excavated materials and wastes. The nominated undertaker will ensure that, for the relevant areas, waste is managed in accordance with Policy 4A.1 of the London Plan.
9.2 EXCAVATED MATERIAL AND WASTE MANAGEMENT STRATEGY
Introduction
9.2.1 This section outlines the strategy for managing surplus materials that will arise from the construction of the Crossrail project. Surplus materials have been categorised as excavated materials and demolition and construction waste.
9.2.2 The construction of Crossrail was expected to generate approximately eight million cubic metres of surplus material when the assessment was completed for the Environmental Statement. The majority of this will be clean material excavated from the tunnel sections of the Crossrail route, the remainder mainly being construction and demolition waste. The estimated breakdown of surplus materials is provided in the following table. These figures estimate the bulked volume of material allowing for the increase in volume of material following extraction.
Clean excavated material (non-contaminated): 6.0 million m3 Construction material: 1.2 million m3 Contaminated material: 0.5 million m3 Demolition material: 0.3 million m3
9.2.3 The project design is continuing to minimise the generation of excavated material by keeping to a minimum: (a) the size of tunnels, shafts and stations; and
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 51 OF 62 (b) building demolition, without compromising the safety or functioning of the railway.
9.2.4 Contaminated material is material that will have been contaminated by previous activities or events and will require particular attention in handling and disposal. It includes hazardous and non-hazardous material. The Environmental Memorandum provides more information on the Treatment of Contaminated Land.
Materials Management Hierarchy
9.2.5 The nominated undertaker and any contractor will use the national hierarchy for sustainable waste management for surplus materials management. The diagram below illustrates the hierarchy in order of preference from the most desirable option at the top, to the least desirable option at the bottom:
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 52 OF 62 Minimisation of Excavated Materials and Waste
9.2.6 Through the design process, the project has sought to reduce the amount of excavated material and waste that will be produced, within the constraints of the project specification.
9.2.7 A well run construction site will minimise waste and its effect, for example, by ensuring the correct amount of construction materials are ordered and by minimising and/or recycling packaging where practicable. Contractors will be required to adhere to appropriate industry standards in this respect so that construction waste will not have a major impact on the overall disposal requirements.
9.2.8 The nominated undertaker will minimise waste from construction activities as far as reasonably practicable. The successful application of waste minimisation techniques and on-site segregation of surplus materials and packaging for recycling should reduce the residual waste from construction sites to a level that will be comfortably absorbed into the existing materials recovering and transfer infrastructure in London without a major impact on the waste management strategy.
Re-use of Excavated Materials and waste
9.2.9 The nominated undertaker and any contractors will re-use as much of the excavated material as practicable within the project area and on or near to the sites where it will be generated.
9.2.10 Suitable projects or other opportunities for reuse of the excavated material will be identified as the detailed construction planning of the project is progressed, preferably within the Greater London area. Demolition waste will similarly be reused, where practicable. Any contaminated material that is reused will be decontaminated prior to reuse, or if reuse is not practicable, will be transported to appropriate treatment facilities or appropriate licensed landfill sites.
Transportation of excavated materials
9.2.11 The revised tunnelling strategy, presented in Supplementary Environmental Statement 3, comprised fewer but longer drives in the central section as compared with the original tunnelling strategy. A key objectives of the construction strategy (presented at 2.1 above) is to remove, where reasonably practicable, excavated material by rail and water transport. On this basis, material would be transported by rail from railheads at: (a) Royal Oak, the site of the western most portal close to Paddington; and (b) Bow Midland Yard which will take material from the north- eastern portal at Pudding Mill Lane, although the tunnel drive from Pudding Mill Lane may be reversed in which case the material
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 53 OF 62 would be transported by conveyor to the Limmo Peninsula for removal by barge. Excavated material would be transported by barge from worksites close to the Thames at the Limmo Peninsula shaft; Isle of Dogs station and Manor Wharf (serving Plumstead portal and the Woolwich station area).
9.3 PROCEDURES

10.2.3 The nominated undertaker will produce a general Ecological Management Plan for consultation with local authorities and relevant Statutory Agencies including a programme for any outstanding surveys, methods for watching briefs, measures to be adopted in the event of the discovery of protected species and measures for the relocation of certain species. In addition, as set out in the Environmental Memorandum, site- specific environmental management plans will be produced for environmentally sensitive sites focusing on ecological issues where appropriate.
10.3 SPECIFIC PROVISIONS
10.3.1 Mitigation measures to protect species and habitats will be considered on a site by site basis and will include the following general principles which will be applied where applicable:
(a) wildlife habitats which will be disturbed by construction work will be surveyed by an ecologist approved by the nominated undertaker prior to commencement of works to inform restoration work, if
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 56 OF 62 required and where appropriate; (b) prior to work commencing, sites will be checked for protected species by an ecologist approved by the nominated undertaker. Where protected species are identified, either prior to the works (through surveys), or during the works, Natural England will be contacted to agree appropriate measures for implementation; (c) appropriate control measures will be adopted in the event that invasive alien species are found on site to ensure that they will not be inadvertently spread along the route; (d) procedures will be implemented to ensure that species specified in Schedule 9 of the Wildlife and Countryside Act 1981, as amended, are not knowingly introduced or caused to grow in the wild; (e) temporary work areas including site access will be situated, as far as reasonably practicable, on previously used sites or amenity grassland of low conservation value; (f) where practicable habitat removal (particularly woodland and other trees) will take place outside the breeding bird season (approximately 1st March to the 31st July) to avoid impacts on nesting birds. Where this is not practicable, all woodland and scrub will be checked by a specialist for nesting birds before removal. If any are identified, appropriate mitigation measures will be agreed with Natural England and implemented; (g) after construction, habitats or ecological features that have been affected by construction activities will be reinstated or allowed to recolonise so that (so far as is reasonably practicable), they recover to their pre-construction condition; (h) where appropriate, landscape planting (other than ornamental and specimen tree planting) will be undertaken using native species typical of the area, as far as reasonably practicable obtained from local sources. For landscaping in the vicinity of the railways, the species will be selected with regard to the potential impact on railway operations, subject to any required approval of the local planning authority; (i) impacts on adjacent wetland habitats and watercourses will be avoided by appropriate design of site drainage and by use of construction techniques to maintain existing drainage patterns along appropriate sections of the route; (j) topsoil and subsoil will be stripped and stored separately and reinstated appropriately as soon as reasonably practicable to minimise adverse impacts to the soil structure; (k) topsoil and the seed bank which it contains will be replaced along the works as close as reasonably practicable to the location from which it was taken. This is particularly important for areas of nature conservation interest; (l) appropriate construction management practices will be adopted on site to minimise the risk of indirect impacts to adjacent habitat (for example, direct incursions, pollution); (m) where appropriate, construction activities will be screened to protect nature conservation sites; and
CONSTRUCTION CODE (ANNEX 1 TO THE EMR) – ISSUE 7.0 31/07/08
PAGE 57 OF 62 (n) where open spaces, sport and recreation facilities have been used as worksites during construction, as far as reasonably practicable, those sites will be reinstated to their former use in consultation with the local authority or other responsible statutory agency.
10.4 PROTECTION OF TREES
10.4.1 The nominated undertaker will use reasonably practicable measures to minimise the loss of trees. Any essential remedial or protective work to trees adjacent to construction activity will be carried out by suitably trained or qualified personnel using recognised methods in accordance with BS 5837 "Guide for trees in relation to construction".
10.4.2 Appropriate protection measures for tree protection will be implemented as specified in BS 5837: 2005. This will include protective fencing and prohibition of storing or dumping materials within the protected area.
10.4.3 For specific worksites where mature tree loss is a concern, such as Finsbury Circus, a landscape management plan will be drawn up by the nominated undertaker as part of the environmental management plan process The plan will be discussed with the local planning authority and in preparing the plans the nominated undertaker will take into account their observations. The plan will cover such issues as tree protection measures, monitoring during construction, replanting and post- construction monitoring.

Executive Summary This report assesses different options for the design arrangement of the building and options for using viable renewable energy sources with a view to justifying or ruling out their inclusion in the GAF Training Centre in order to reduce carbon dioxide emissions from the development. The following systems have been considered: Improved building fabric Air tight construction Decentralised Energy (DE) Ground Source Heating / Cooling Biomass Boilers Photovoltaic Systems Solar Thermal Water Heating Combined Heat and Power Wind Generators Rainwater harvesting
At this early stage in the project, this high level report has been produced based upon outline information to allow the need for further studies to be reviewed or undertaken as required.
In accordance with the London Plan Policy 5.2, and The London Borough of Redbridge’s’ Supplementary Planning Document: Sustainable Design and Construction requirements, the building is required to achieve a 25% reduction in CO2 emissions over that stated in Approved Document Part L2A 2010, and must also achieve a BREEAM Excellent rating.
A 3D building model was built using Integrated Environmental Solutions with the latest plans available, the model was then simulated over time in Approved Software IES compliance 6.4.0.12 to show how each of the above building design options helped to reduce the buildings carbon footprint in accordance with AD Part L2A 2010.
The building form was initially looked at to ensure that a ‘lean and clean’ approach was taken to minimise energy use. The results showed that by altering the building from limiting figures within Part L to improved good practice figures for the construction, air permeability, lighting and auxiliary energy use within the building reduced Building Emission Rate (BER) reduced form 31.6 kg/CO2 m² a year to 24.6 kg/CO2 m² a year. This equates to an overall saving of 10.4 tonnes of CO2 a year.
Although the ‘Lean and Clean’ approach to the building was found to provide significant carbon savings, these measures were not enough to meet the requirement of a 25% reduction in the ‘Notional’ Target Emission Rate (TER) equating to a BER of 16.2 kg/CO2 m² a year. Therefore the ‘Green’ approach was taken to further reduce the BER.

A brief summary of simulation results is shown in the table below:
Emissions LZC % CO2 BREEAM
System (kgCO2m²year) Saving Ene1 Credits
Baseline Building 31.6 - 0 ‘Lean’ building Approach 24.6 22% 2 AD L2A 2010 Target Emission Rate (TER) 21.6 12% - ‘Lean’ + 200m² Photo-voltaic (PV’s)(1) 14.9 40%(2) 11 ‘Lean’ + Solar Thermal 21.6 12%(3) 2 1. The minimum performance requirements for achieving a BREEAM Excellent rating are an EPRNC ratio of 0.36 (normally 6 credits) and a 25% improvement on the Building Regulations TER. So although a 31% reduction from the TER has been achieved, in this instance additional PV’s are required to meet the EPRNC rating of 0.36. 2. 200m² of Solar PV’s provide a 40% reduction in CO2 emissions from the ‘Lean’ building 3. SHW provided a 12% reduction in CO2 emissions from the ‘Lean’ building
The simulations run showed that by utilising either an Air Source Heat Pump or Gas fired heating system coupled with either or both a Solar Photovoltaic Cell array for generating electricity or Solar Hot Water system, the building was able to meet the required 25% reduction in CO2 emissions from the 2010 Target Emission Rate and meet the minimum requirements for BREEAM credits Ene1 and Ene4 in order to achieve an ‘Excellent’ rated building. Although using PV’s is a selected path for the project, the final array size may be increased or reduced as the energy demand of the building changes, however BREEAM Excellent will still be met on the development.
Due to space and access restrictions on site, Ground Source Heating and Cooling system, Biomass boilers, CHP and Wind generators were all discounted at this stage for inclusion in the GAF Training facility development.
It is important to note that the assessment has been undertaken whilst the building form is generally fixed, but full information about the room and space uses has not been fully defined, plant capacities have been assessed from initial information but at this stage are not definitive and are subject to change.

1 Introduction
The Greater Anglia Franchise (GAF) Training Centre is a new two storey building with a floor area of around 1500m², housing male and female changing and showers, and comms facilities on the ground floor and mixed use offices and training rooms on the first floor.
The Building is an extension of the exiting Light Maintenance Depot Building which forms part of the Ilford Stabling Yard development.
As the site is in-between an existing building and a series of train tracks, the long narrow site has dictated a long rectangular building of approximately 80m x 12m in size.
Although the new building is classed as an extension, it is over 500m² and has been considered as a new build and is subject to meet the following requirements for planning:
The London Plan- Policy 5.2, and the London Borough of Redbridge, Sustainable Design and Construction- Supplementary Planning Document, which both require that the building be designed to reduce carbon emissions by a further 25% from the AD L2A 2010 TER, achieve BREEAM Excellent and ensure that the building has been designed using the following hierarchy:
1 Be lean (use less energy) 2 Be clean (supply energy efficiently) 3 Be Green (use renewable energy)
This report has been produced at ‘Grip Stage 3’ pre- planning stage in order to demonstrate how the new GAF Training centre will fully comply with the above requirements and satisfy BREEAM Credits Ene1 and Ene4 to ensure an ‘Excellent’ rated Building.

2 ‘Lean’ building approach
Building Regulations Approved Document Part L2A ‘Conservation of Fuel and Power’ defines minimum standards for building fabric and fixed building services. With regard to the new GAF Training Building, the ‘Lean’ aspect of the design covers aspects such as the building construction arrangement and air tightness to minimise heat loss in the winter and minimising energy use from the use of energy efficient services, in this instance internal lighting and high efficiency fans for moving air around the building. Table 1 below shows the limiting design standards for a new build taken from Approved Document Part L2A 2010, compared to those that are proposed for the new GAF Training Building: Table 1: Limiting L2A 2010 figures against the proposed elements of the GAF Training room Limiting AD L2A Backstop Building attribute Figure GAF Training Building- ‘Lean’ Ground Floor 0.25 W/m²K 0.2 W/m²K External Wall 0.35 W/m²K 0.2 W/m²K Roof 0.25 W/m²K 0.15 W/m²K External Glazing 2.2 W/m²K 1.5 W/m²K Air permeability 10 m³/(h.m²) at 50 pa 5 m³/(h.m²) at 50 pa Lighting Efficiency 55 lm/W 65 lm/W Specific Fan Power 2.1 W/l/s 1.6 W/l/s
2.1 Results The full set of results can be found in Appendix A, however the ‘Lean’ approach was found to have reduced the BER by 7kg/CO2 m² an year, equating to 10.4 tonnes of CO2 per year.

3 ‘Clean’ Systems
Another requirement of the London Plan is that for the proposed development, during preliminary design, ‘Clean’ systems are considered to ensure that energy is supplied efficiently throughout the new building. This included considering either using boilers or chillers local to the building to ensure that there is a minimal amount of energy lost in long distribution networks or for instance a district heating or cooling system, where extending an existing heating or cooling system could save energy, where despite there being long distribution networks, there may be the opportunity to use ‘free’ waste heat from an adjacent building.
3.1 Findings Both of the above options could be utilised in the new GAF Training Building. The building has been designed so that all boilers are located in a centralised plant room or in a roof top area to minimise any flow and return pipework. The heating to the building is likely to be generated in one of two ways; Either an Air Source Heat Pump (ASHP) or via Gas Fired Boilers system. In addition, at this early stage in the design, as the building is an extension of the Light Maintenance Building, it is a recommendation of this report that a further independent study is performed to asses to potential for extending the services from the light maintenance building to serve the new GAF Training facility. However, until this study has been completed, it is not be known if this would be suitable as is dependent on the location of any existing plant, and if there is any spare capacity on the existing systems.

4 Ground or water source heating and cooling
Utilising the fact that the ground is maintained at a relatively constant temperature of around 12°C all year round at depths of over 1.5m, the natural energy stored within the earth or nearby water course can be extracted and used to either heat buildings in the winter or cool buildings in the summer. There are several options for a system, each relying on a heat pump located within the building:
Ground source open loop borehole system An open loop system comprises of two bore holes which are drilled to the depth of the underlying aquifer. Water is pumped from the aquifer through one extraction borehole and either passed through a heat exchanger in the summer, to provide cooling to the building, or a heat pump during the winter to provide low grade heating water at approximately 40°C. Water is returned to the aquifer via the second borehole.
Vertical closed loop A vertical closed loop system comprises of a number of pipes that run vertically in the ground. A hole is bored into the ground and U shaped pipe pairs are positioned in a loop. Heat transfer takes place between the surrounding ground and the circulating water within the pipework. Vertical loop systems are typically used when there is a limited area of land available. Bore holes are spaced 5-6 metres apart and drilled to a depth of between 15-150 metres. They benefit from higher ground temperatures than is available for shallow trenches and are therefore more efficient. They can also be integrated within piled foundations
Horizontal closed loop A horizontal closed loop is composed of pipes that run horizontally in the ground. A long horizontal trench, deeper than the frost depth (typically over 1500mm), is dug and U-

shaped coils are placed horizontally inside the same trench. The closed loop system uses the temperature of the ground to provide heating or cooling to a building. Water is circulated around the spiral pipework and passes through heat exchanger or heat pumps as with the open loop system. Horizontal trenches are dug 1.5-2 metres below ground level and are best suited for smaller systems.
Slinky closed loop A slinky closed loop field is installed in the horizontal orientation in a similar manner to horizontal closed loop systems but where the pipes overlay each other. Where there is not adequate room for a true horizontal system, a slinky loop field is an alternative solution.
Water course cooling Like a ground source system, a local water course can also be used to extract energy from. Typically this would be in an open loop configuration were water is pumped to and from the building from a water course or in a closed loop system where a slinky pipe arrangement is placed at the bottom of a water source.
4.1 Site specific solutions Due to limited space available on site, and potential issues with existing buried services, the use of either an open or closed loop ground source heating or cooling system for the proposed GAF Training building is not considered to be feasible.

5 Biomass Boilers
Biomass is a solid fuel that is normally found in two forms; traditionally either in the form of wood or food waste. In the instance of wood, the fuel is normally provided either as pellets or wood chips. Pellets are generally more expensive but have the advantage of guaranteed low moisture content which increases efficiency. More recently multi-fuelled burners have been fitted to biomass boilers that enable them to burn wood pellets, wood chips or food waste. Like in a conventional boiler the fuel is then burnt under a heat exchanger where water is passed through and can be used for either heating or hot water use. For a Biomass boiler to work most effectively it should be sized to be able to cover a large part of the total heating load in the winter months, and modulate down to cover the base heating load of the building in the summer for hot water use, this would enable the boiler to run continuously all year round. However in the instance of the GAF training facility, the base building load in the summer is very small so would only have limited use in the summer. A biomass boiler installed within the guidelines of the Micro-generation Certification Scheme (MCS) could qualify for help with installation costs, and generate an annual income via the Renewable Heat Incentive (RHI) Scheme.
5.1 Site specific solutions Although installing a Biomass boiler on site is technically possible, the weekly delivery of fuel to a secure and busy site like Ilford would cause disruption, furthermore there is little available space on the site to accommodate the necessary fuel storage. It is a recommendation of this report that the use of Biomass is not given further consideration.

6 Solar Photovoltaic Array
Solar Photovoltaics operate by converting solar radiation from the sun into DC electrical power. Efficiency of the PV cell can vary depending on their construction make-up, however, PV’s are now generally around 15% efficient. PV’s can be mounted on sloped or flat roofs; can be integrated into local shading devices or can be ground mounted. They work most efficiently positioned at an angle, but can be mounted flat, however flat mounted panels would not be classed as ‘self-cleaning’ and would require additional maintenance. Solar PV’s have the additional advantage of being easily retrofitted on to a project with little disruption to the existing building services. Solar PV’s have become very popular within the last 5 years in the UK, due to the introduction of the Feed In Tariff (FIT) and because of this the costs of installing PV’s has reduced. It is a recommendation of this report that Solar PV’s should be considered at detailed design stage for the GAF Training Building. Current preliminary calculations indicate that around 200m² of roof mounted PV’s could be used to achieve the target of 25% reduction in the TER.
6.1 Land use The Photovoltaic cells would be installed on the roof of the building and no extra land will be occupied with the system. Access would need to be provided to the roof for cleaning the system.
6.2 Local planning requirements The location of the PV cells would be coordinated with the architect to ensure an aesthetically pleasing location. We would not anticipate major local planning issues for the addition of a PV system.

GAF Training Facility – Energy Assessment RED/11/8 Document Number C161-MMD-T-XST-CR112_WS129-50012 Rev P1
6.3 Noise The photovoltaic system has no moving parts and is therefore silent.
6.4 Impact on Carbon Emissions Carbon emissions savings can be calculated by applying the carbon emission factors for gas and electricity to the annual energy consumption figures, as shown below:
Carbon dioxide conversion factor – displaced electricity = 0.529kgCO2/kWh
Equivalent electricity usage = 23,400kWh/year x 0.529 = 12,378.6 kgCO2 a year
Carbon saving = 12,378 kgCO2 a year
A full table of results can be found in Appendix A
6.5 Availability of Grants Although it is unlikely that there are any available grants for the installation of a Solar PV Array, as mentioned previously any certified installation will qualify for the Feed In Tariff (FIT).
6.6 Effect on BREEAM and Part L Submissions The use of PV’s has a significant benefit for compliance with Building Regulations AD Part L, not least because of the effective ‘free’ on site generation of electricity. The 200m² PV array was demonstrated within the IES model to reduce the Building Emission Rate by 8.3kg CO2/m² per year. This coupled with a lean and clean building for design would help to achieve 11 BREEAM Credits for Ene1, achieve both a building EPRnc rating of 0.36 and achieve a 25% reduction in CO2 emission rates.

7 Solar Hot Water
Solar Hot Water (SHW) systems operate by passing a brine water solution through a vacuum in a series of magnifying tubes exposed to the sun. This sealed system is pumped through a heating coil in a hot water storage vessel to act as a pre-heat to the hot water within the building. Like Solar PV’s, SHW systems work best mounted at a pitch of between 30° to 45° facing south. A preliminary review for a solar hot water system indicates that an array of 50m² of evacuated tube solar hot water panels would be required to provide preheating to serve the domestic hot water for the new building. A Solar Hot Water system would qualify for payments through the Renewable Heat Incentive. Much like the FIT scheme for Solar PV’s, the RHI would award an extra income for every kWh of heat generated by the SHW system
7.1 Land Use The Solar Hot water system at GAF Training Building would be located on the roof and would therefore not require ground floor land. The solar panels could be located on a frame on any of the new flat roof.
7.2 Local Planning Requirements The location of the solar hot water collectors would be coordinated with the architect to ensure an aesthetically pleasing location. We would not anticipate major local planning requirements for the addition of a solar hot water system.
7.3 Noise The solar panels have no moving parts and are therefore silent. The pumps and storage would be located within the plant room and any noise contained within the plant room.

7.4 Impact on Carbon Emissions Carbon emissions savings can be calculated by applying the carbon emission factors for gas and electricity to the annual energy consumption figures, as shown below:
Carbon dioxide conversion factor Gas = 0.198 kg CO2/kwh
Generation from SHW system = 26,500 kWhrs x 0.198 = 5247 kg CO2 a year
7.5 Availability of Grants It is unlikely that there are any available grants for the installation of a Solar PV Array, as mentioned previously any certified installation will qualify for the Renewable Heat Incentive (RHI).
7.6 Effect on BREEAM and Part L submissions
The use of a solar hot water system will reduce the buildings CO2 emissions as the system heat source will operate less frequently. The 50m² array was programmed into the IES model and is predicted to reduce the Building Emission Rate by 3 kg CO2/m² per year. Although this alone was not enough to meet planning requirements, a SHW system could be used with another technology to achieve a BREEAM Excellent rated building.

8. Combined Heat and Power
Combined Heat and Power (CHP) is a system that involves the recovery of waste heat from power generation to useful energy. Essentially a turbine or engine is used to generate electricity that can either be used locally or exported to the grid. A cooling circuit from the engine/turbine is used to draw waste heat away from the machine and is then used as a heating source. The fuel source for CHP is traditionally gas, diesel or bio fuels. These systems are becoming more common in premises which have a simultaneous demand for heating and electricity for long periods such as swimming pools or hotels.
The use of CHP is not suitable for the new GAF Training building, as a large base heating load is required all year round to make the system economical in operation which is not the case in the GAF Training building. This technology has therefore been discounted at this stage.

9. Wind Energy
Wind turbines covert the energy of the wind into power which can be used within the development or exported to the grid. The site conditions for this type of renewable energy source are very important; the average wind speed must be above 5m/s at a height of 10m for significant amounts of time, additionally any obstructions, such as buildings and large protected trees would also have an impact on the efficiency of the system.
The average wind speed at the grid reference TQ 44 86 (Postcode: IG1 1TS) has been found to be 4.6m/s which is lower than the minimum required to provide an efficient system.
Because of the lack of available wind speed on site and the large numbers of obstructions on the site from adjacent buildings, a wind turbine installation has not been considered for use at the GAF Training Facility Ilford.

1 Introduction
1.1 Application Background
Scheme Crossrail
Applicant Crossrail Limited
Applicant Address 25 Canada Square, Canary Wharf, London, E14 5LQ
Site Address Ilford Yard, Ley Street, Ilford IG1 4BP Town and Country Planning Act Application for Replacement Greater Anglia Franchise (GAF) Training Centre, provision of new Back up Control Facility (BUCF) and Proposed Parking, Description including the demolition of the existing GAF training centre and a permanent change of use to staff car park associated with the adjacent Ilford railway yard.
1.2 Terms of Reference This Transport Statement (TS) has been prepared in support of the Town and County Act (TCPA) Planning Application (RED/11/8) for the replacement GAF training centre and a new car park at Ilford yard. Development of the design proposals as part of the scheme has resulted in some elements of the proposed works being outside the Crossrail Act limits of land to be acquired or used (LLAU). As a result, planning application is necessary for the works which fall into two areas located at the western and eastern end of Ilford railway yard.
The wider Crossrail works will not only displace existing parking at the depot site, but the new occupancy will also introduce its own parking requirement. The need to provide this parking has led to the requirement for this planning application. The purpose of the TS is to identify if the proposed works under this application are likely to affect the local and strategic highway network. The TS covers both construction and operational phases of the scheme.

2 Site Location
2.1 Location and its Setting
The existing Ilford railway yard occupies a large site within the London Borough of Redbridge which has rail depot facilities adjacent to the Great Eastern Mainline (GEML). The site is located between Ilford railway station (to the west) and Seven Kings railway station (to the east). The site lies wholly within the London Borough of Redbridge and is located to the east of Ilford town centre. Griggs Approach (an elevated highway over the railway) separates the site from the edge of Ilford town centre. A triangular shaped area to the north west of the site is currently used as a builder’s yard. A site location plan is shown below.
Figure 1.1: Site Location Plan
Vehicular access to the west of the site is from Ley Street. Vehicle access to the east of the site is through Aldborough Road South. The site has been used for railway activities for many years. The Greater Anglia Franchise (GAF) and Bombardier Transportation (BT) currently use the site.

2.2 Description of Application . This application is for the replacement GAF training centre, including the provision of a backup control facility (BUCF) at the south west corner of the existing GAF light maintenance depot shed to the east of the site. The site covering these works is approximately 0.09 hectares with a gross floorspace of approximately 1438 m². The application site also includes for the demolition of the existing GAF training centre to the west of the site (a brick built single storey building) to provide additional parking facilities. The site covering the new proposed car park is approximately 1800 m², and is roughly rectangular in shape. The two areas of the proposed works are shown on drawings contained in the accompanying drawing pack document no. C161-MMD-T-XPA-CR112_WS129-50006.

3 Baseline
3.1 Local Road Network
The perimeter of Ilford depot is bounded by Ley Street to the north, Giggs Approach to the west, A118 High Road to the south and Aldbororgh Road South to the east, all of which are subject to a 30mph speed limit.
Ley Street is a single lane bidirectional road. Frontages on Ley Street are predominately residential with pockets of light commercial units and a number of small shops. Ley Street connects Ilford with the A12 Eastern Avenue. Ley Street is part of a bus route.
Griggs Approach (an elevated highway over the railway) immediately to the west of the site separates the site from the edge of Ilford town centre and connects Ley Street with A118 High Street.
To the south of the site is the GEML, beyond which is A118 High Road. The A118 High Road is a main borough distributor road which is part of the Strategic Road Network (SRN) in London. It is a single lane bidirectional road. The road is characterised by mix of uses including residential, light industrial and car parking. A118 High Road is part of bus route.
Aldborough Road South to the east of the site is predominately a residential road and accommodates Canon Palmer Catholic High School. The road operates one-way from its junction with A118 High Road for approximately 100m to the junction with Lombard Avenue. Beyond this, it operates as a two-way road.
3.2 Traffic Flow Data
In the absence of existing traffic flow data, it can be assumed that the A118 High Road carries the largest volume of traffic followed by Ley Street, Giggs Approach and Aldborough Road South.
3.3 Public Transport
Ilford railway yard is served by relatively good public transport links. The Public Transport Accessibility Levels (PTAL) for the western end of the site is classified as 6a (excellent). The eastern end has a PTAL level of 2 (poor). Rail Ilford railway station is located approximately 800m to the west of the site and within a 15 minute walk.
Seven Kings railway station is located about 550m to the east of the site and is under a 10 minute walk. Page 4 Document uncontrolled once printed. All controlled documents are saved on the CRL Document System © Crossrail Limited Decal Template: CRL1-XRL-Z-ZTM-CR001-50018 Rev.1.0
Town and Country Planning Act Application - Planning Statement RED/11/8 Document Number C161-MMD-T-XST-CR112_WS129-50010 Rev 2.0
Passenger services at both stations are operated by Greater Anglia and most trains run between Shenfield and Liverpool Street. The frequency of the trains is 6 per hour. Both stations are located in Travelcard Zone 4.
Bus There are two daytime and one night-time bus services which operate close to Ilford railway yard.
Route 169 operates between Barking and Clayhall; it runs along Ley Street at a frequency every 10mins.
Route 86 operates between Harold Hill and Stratford; it runs along A118 High Road at a frequency every 7 minutes. The night-time N86 operates the same route as the daytime 86 services at a frequency every 30 minutes.
Bus stops for the 169, 86 and N86 are located within 200m of the site.
Routes W19, 179, 462, 145, 147, 167, 128, 25, 123, 364, 366, and 150 serves stops on High Road Ilford approximately 350m from the western entrance of the site. Frequency of these services range from every 3 to 16mins.
3.4 Pedestrians and Cyclists
Pedestrian activity in the immediate vicinity to the western site entrance on Ley Street is assumed to be low as there are no key attractors in the close vicinity.
Canon Palmer Catholic High school is located in close proximity to the eastern site access on Aldborough Road South. Therefore, it is assumed that pedestrian levels on Aldborough Road South are high during school term time over periods when pupils are going to, or leaving school.
No designated cycle routes are present on roads to the west or north of the site; however a shared pedestrian/cyclist path runs beneath Giggs Approach to the south of the site. Aldborough Road South to the east of the site is designated as a route signed for cyclists.

4 Proposed Works
4.1 Replacement GAF training centre including the provision of a backup control facility (BUCF) The replacement GAF training facility building is needed to cover for the loss of the training facility to the west of the site. The training facility is used for inductions and technical training sessions. Temporary training facilities will be provided off site whilst the new training centre is being developed. The BUCF is needed to control the whole Crossrail route. The BUCF is not a duplicate control centre but a stand-by facility to be used on an infrequent basis.
4.2 Provision of Permanent Staff Car Park Currently there are approximately 130 parking spaces on the site overall serving the two occupants of the site (GAF and BT). Crossrail will also operate from the site in the future which will result in additional car parking requirements for all three companies. It is proposed that a total of 52 car parking spaces will be made available under this application as set out on drawing no. C161-MMD-T-CR112-SD007-1-40102. The standard car parking spaces will be 4.8m x 2.4. Within the site application boundary there will be an increase in 46 car parking spaces. Provisions for parking requirements for the new GAF training centre will be facilitated by utilising the six spaces in an existing car park at the eastern end of the site. Increase in site-wide parking will be from 130 to 166 spaces. The total net increase in site- wide parking spaces is therefore 36 spaces. There will be no provisions to provide additional cycle parking or disabled parking spaces under this application as there are sufficient provisions elsewhere within the Ilford railway yard for them.

5 Construction Phase
5.1 Construction Lorry Numbers
It is estimated that approximately 162 HGVs are needed to carry out the works during the 6 month construction period. Of these, 60 HGVs are needed to take material away from the site and 102 HGVs for deliveries to the site. This represents a total of 324 two-way HGV movements.
The table below sets out the sequence of the proposed works, the estimated numbers of HGVs likely to be generated by each works stage and the associated vehicular access points. *Estimated Estimated average Construction Constriction HGVs (per Vehicular Stage Description of Works Period day) Access Aldborough Road 1 Construction of GAF training centre 3 months 2 South Demolish existing GAF training 2 centre and site clearance 1 month 6 Ley Street
3 Construction of permanent car park 2 month 2 Ley Street *two-way movements
It can be seen that the potential generation of HGVs associated with the proposed works is small. These levels of HGVs are expected to form a very small percentage of total traffic and would not cause any adverse impacts on the local roads or to the wider network.
Although the average number of daily HGV movements accessing the site via Aldborogh Road South is low, it is recommended that any movements will be restricted to periods outside the opening and closing hours of Canon Palmer Catholic High School.
All construction workers are expected to use public transport. There will be no parking spaces available to construction workers on site.
5.2 Lorry Routes Lorry routes are expected to use the routes set out in the Crossrail Act 2008 Lorry Management Plan (LMP) for London Borough of Redbridge Document Number: C161-XRL- T-QAP-CR112-5001. This shows routes between the sites and the nearest strategic road, which in this case is the A118 High Road. The LMP states that the split of lorry movements associated with the Ilford railway yard is expected be 5% via Aldborough Road South and 95% via Ley Street, however it is anticipated that there will be a slight rise in construction traffic at the eastern end. The revised split of lorry movements is expected to be 10% via Aldborough Road South and 90% via Ley Street.

Town and Country Planning Act Application - Planning Statement RED/11/8 Document Number C161-MMD-T-XST-CR112_WS129-50010 Rev 2.0
5.3 Traffic Management Good traffic management principles will be employed during the construction period in line with section 4.2 of the Crossrail Construction Code. This represents a stringent construction management code.
5.4 Access Assessment Vehicular swept path analysis has not been assessed specifically as part of this TS as both the Ley Street and Aldborough Road South access points are already used by HGVs for deliveries. It is assumed that site accesses will be subject to a safety assessment as part of the design process and all vehicle movements into and out of the site are to be under banksman control.

6 Operational Phase
6.1 New car park usage Vehicular ingress and egress to the new car park is to be from the existing site access on Ley Street. It is envisaged that the new car park shall be operational in 2016. The depot will remain 24 hour operation with shift working. Existing staff and new Crossrail staff will need to make journeys to and from work outside normal operating hours of public transport. For this reason, the Ilford depot needs additional parking spaces in order to remain operational. The car park will be for use only by depot staff, and will not be accessible to the general public. Crossrail will employ approximately 90 staff to work over 3 separate shifts over the course of 24 hours. It is assumed that 30 will work on each shift. Of the 52 parking spaces being made available under this TCPA planning application available, 18 spaces will be made available to Crossrail staff and the remaining 34 to BT. There are six existing car parking spaces allocated to the GAF training facility. It will be ensured that these six spaces are accommodated in the existing car park to the east of the site where the new GAF training facility is to be located. There is no requirement to provide any extra spaces over and above the 52 spaces proposed. Staff working on daytime shifts will be encouraged to use public transport, walk or cycle to work and staff on night shifts will be encouraged to car share with colleagues so that demand for parking spaces can be managed properly. In the worst case, it is expected that an extra 46 car trips will be arriving at the site due to the works proposed under TCPA ref. RED/11/8 and 46 will be leaving the site in three periods over the course of 24 hours. It is assumed that these trips will occur outside the peak traffic hours (8:00-9:00am and 5:00-6:00pm) and therefore the operational phase of the new car park is not expected to cause any adverse impacts on the local roads or the wider road network.

7 Assessment of Effects
7.1 Construction Period The proposed works are expected to generate small volumes of construction traffic and this is not expected to cause any adverse impacts on the local or wider road network.
Local bus service operations, pedestrian and cycle routes are expected to remain unaffected during construction and no temporary effects are anticipated.
7.2 Operational Period In order to reduce the risk of local congestion and delays during the operational period, any ‘work-related’ trips will be made outside the peak hours. Therefore, the increase of daily trips associated with the new staff car park is not likely to affect the local road or wider road network.
7.3 Conclusions The proposed development will not result in any adverse impacts on the local road or wider road network.
No significant temporary or permanent adverse effects are anticipated during construction or operational phases of the proposed works under this application. Pedestrians and cyclists are not expected to be affected, therefore no residual long term effects are anticipated.
The permanent car park will not impact on the surrounding area in any significant way. The location selected for the car park is considered a less sensitive location than that submitted previously (180 Ley Street) which was in close proximity to residential receptors.
In conclusion, the scheme accords with Development Plan policies, and given the national significance of the Crossrail project, of which this is a key element, the Council is requested to support and approve the application.
