1. INTRODUCTION

1.1 This report provides the specialist noise and vibration assessment for Route Windows NE1 to NE17 and remote Window R1 (Pitsea Sidings).

Overview of Crossrail Works in the North Eastern Route Section

Orientation plan of the north eastern route section

Permanent Works 1.2 Crossrail services within the north east route section will run on the existing electric suburban tracks of the Great Eastern Mail Line (GEML). Little new rail alignment will be created, although new track will be required to provide a freight loop between Goodmayes and Chadwell Heath in order to replace an existing loop at Manor Park, which will be removed. Also, the reconstruction of Shenfield station will be undertaken as well as new junction works at Ilford.

1.3 Crossrail will require new or extended platforms at several stations in order to accommodate its 200 m long trains. At Romford and Ilford, new station buildings and other facilities will be provided as well.

1.4 Crossrail’s other major facility on this line is a new depot and stabling sidings to the west of Romford Station and south of the GEML. This is linked to the eastbound and westbound Crossrail running lines by a dive-under (rail underpass) enabling Crossrail trains to access the depot without hindering services on the main lines. Stabling sidings will also be provided on re-modelled existing sites at Gidea Park and Shenfield. New sidings will be constructed at Aldersbrook (near Ilford) to facilitate fit- out of the Crossrail tunnels, and at Pitsea for disposal of excavated material.

Construction Works 1.5 Platform extensions, which will be undertaken at several stations, will involve:

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 2 17 February 2005

• break out and removal of existing surfaces and ramps;

• excavation of foundations to about 1 m depth;

• construction of platforms either using crosswalls and pre-cast concrete planks, using a proprietary system or traditional construction;

• fitting of reinforced concrete screed, pre-cast concrete copings, tactile strips and the levelling of the surface;

• adjustment of track alignments, if required; and

• modifications to OHLE and signalling as necessary.

1.6 Proprietary platform extension systems may be used. These may vary with the construction activities.

1.7 Subject to possession planning requirements and excluding final commissioning, platform extensions will generally take between one and three months to complete.

1.8 Construction methods for each of the works are described in their route window; for example, with respect to construction of station buildings, stabling facilities and grade separated crossings. The construction works, where they take place on or near to the railway, may need to be undertaken during ‘possessions’, when the railway is closed to normal passenger and freight services. These possessions generally take place at night, at weekends or over public holidays. Where time periods for the works are given in this chapter, they may be subject to alteration to accommodate possession planning requirements (ie times to be negotiated with the train operating companies and Network Rail, when the works can be undertaken during temporary closure of the railway) and final commissioning, which may need to be completed for the corridor as a whole.

1.9 Enabling works will be required prior to the main construction works. These may take up to 12 months at each site, although at locations where only minor enabling works are required the durations of these works could be much shorter.

The Route Windows 1.10 The scale of the works along the route varies. Relatively minor works, such as station platform extensions, will take place in some route windows with more substantial works, such as the development of Romford depot, taking place in others. Table 1.1 summarises the main works (excluding enabling works) that will take place in the north east section. Those route windows containing the more substantial works are highlighted with shading.

1.11 The level of detail that is reported in subsequent sections for route windows NE1 to NE17 and R1 is commensurate with the extent of works that is proposed in each of these route windows.

2. ENVIRONMENTAL BASELINE AND ASSESSMENT OF IMPACTS – STRATFORD STATION TO SHENFIELD STATION

ROUTE WINDOW NE1 – STRATFORD STATION

Overview 2.1 The main works in this route window, which is located in the London Borough of Newham, will involve ensuring that platform five is suitable for use by Crossrail trains. The works will involve the widening of platform five, which forms part of island platform three/four/five. Some refurbishment works, in addition to the fitting out of new platform furniture, will also be undertaken on the platforms. Overall, the construction works will take approximately four months to complete.

2.2 The current platform four (used by the DLR services) will be filled in to provide more space on platform five, the westbound Crossrail platform. DLR is constructing a new platform arrangement for its services and has planning permission for these works (received September 2004). The new DLR platform arrangements will be in place by 2006.

2.3 The works at Stratford Station will be carried out within the existing railway corridor at the eastern end of the station from sections of the existing platform three/four/five. In addition, there will be a site adjacent to the current station track that will be used for storage. Plant and materials for platform construction will be delivered by both rail and road. Excavated materials will be removed by road or rail.

2.4 The main construction plant to be used at the worksite will include cranes, excavators, piling rigs and mechanical breakers. Construction traffic will access the worksite via the station access point from Meridian Square, off Great Eastern Road (A11).

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 6 17 February 2005

2.5 Approximately four lorries in total per day will access the worksites during a three week peak construction period. At other times the worksite will typically be served by one lorry per day.

2.6 The area around the station comprises a large area of railway land to the north of Stratford station, which is currently the main Channel Tunnel Rail Link (CTRL) worksite. Other parts of the route window are relatively built-up, with industrial areas to the southwest and residential areas to the east.

Baseline 2.7 One baseline noise survey was deemed necessary within this route window, its location and duration are listed in the following table and identified on Drawing No. 1E0415-E1E000-E01-F-00001.

Long-term Medium term Short-Term Location Address (1 week) (24-hours) (3-hours) The Carpenter’s & NE06 x Docklands Youth Centre

2.8 A long-term monitoring survey was undertaken at the Carpenters College and Docklands Youth Centre (NE06) in Gibbins Road, where the noise-monitoring equipment was installed on the roof of the building, overlooking the trade entrance of Stratford Station. The daytime LAeq,12hr baseline level was 65 dB, with a LAmax,F level of up to 95 dB. The night-time LAeq,8hr baseline level was 59 dB, with a LAmax,F level of up to 89 dB. The local noise climate was dominated by train movements, with faint road traffic noise audible from the A118 and occasional aircraft movements.

Impact Assessment – Temporary Impacts

Impacts during Construction 2.9 Temporary impacts from construction activities are illustrated on Drawing No. 1E0315-E1E100-E01-F00001.

Noise from Surface Construction Activity 2.10 Appendix A provides tables for each route window giving the predicted durations of significant impacts for representative receptors. Each listed receptor is representative of one or more dwellings or other noise-sensitive location. Also included in the tables is an estimate of the numbers of dwellings that may be eligible for temporary re- housing and/or noise insulation. Appendix A should be read in conjunction with both the text below and the Construction Noise Assessment Plans provided in Volume 8 of this Technical Report.

Construction Sites and Works including Onsite Traffic 2.11 The construction programme is scheduled to run for approximately four months and is split into 4 phases.

2.12 No noise impacts are expected to occur due to construction works programmed at Stratford.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 7 17 February 2005

Offsite Road Traffic 2.13 Construction vehicles will only use the highway during the daytime (07:00 to 19:00). At façades overlooking roads used by construction traffic, the existing hourly LA10 during the daytime is predicted to increase by < 1 dB. There are therefore no significant impacts arising from construction traffic.

Vibration from Surface Activity 2.14 The plant likely to be required to construct the Crossrail elements at Stratford Station has been reviewed to identify sources, which may produce levels of vibration sufficient to cause adverse comment from the occupants of buildings, or cause damage to buildings.

2.15 The construction information provided by Crossrail indicates that concrete breakers and a wacker plate are required during the set-up of the construction site, and that concrete breakers are also required during platform works.

2.16 No significantly substantial buildings or structures have been identified on the construction site that would require significant demolition activities, and therefore it is considered that the plant required to undertake the set-up of the construction site will not be sources of significant vibration. Vibration levels from the platform works are unlikely to be significant at the nearest potentially sensitive receptors, assuming that the breakers are not vehicle mounted.

2.17 Vibration levels are not expected to exceed the threshold of significance for building damage at any receptor during any of the proposed works.

2.18 The construction activities required at this site are likely to give rise to vibration levels that are below those that correspond to a semantic rating of ‘a low probability of adverse comment’. Due to the temporary nature of such works, and with appropriate mitigation, the impact to occupants of the buildings is not likely to be significant.

2.19 No listed buildings, or receptors that are potentially more sensitive to vibration than residential uses, such as precision laboratories and operating theatres, have been identified that are significantly close to this worksite.

Mitigation and Residual Impacts during Construction

Noise from Surface Activity

Construction Sites and Worksites including Onsite Traffic 2.20 Hoardings of a minimum height of 3.6 m would be provided along the southern and eastern boundaries of the station working area and 2.4 m around the site compound. Compressors, generators and other static plant would be located in noise reducing enclosures. This corresponds to Tier 2 mitigation.

2.21 In this route window, no properties are likely to qualify for noise insulation or temporary re-housing and there would be no significant residual noise impacts.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 8 17 February 2005

Offsite Road Traffic 2.22 There are no significant residual impacts.

Vibration from Surface Activity 2.23 There are no significant residual impacts.

Impact Assessment – Permanent Impacts

Impacts during Operation

Noise from the Surface Railway 2.24 In this Route Window there are proposed changes to the railway (permanent way) infrastructure to the east of the Pudding Mill Lane tunnel portal. To allow construction of the new Crossrail alignment, the DLR will be realigned and the existing DLR station at Pudding Mill Lane removed. The existing viaduct will be widened and a new Pudding Mill Station built on the southern side. The abandonment of the existing DLR alignment will allow the new Crossrail line to be constructed. The existing Up Electric Line will be decommissioned and removed. A Level 2 (assessment based upon changes in railway traffic on existing lines and on other infrastructure alterations but no detailed modelling) assessment has been carried out for this area.

2.25 There will also be a change in the composition of railway traffic in the area with the implementation of Crossrail. The predicted noise changes attributable to the infrastructure and forecast railway traffic changes in the vicinity have been calculated taking account of the various changes.

2.26 The resulting changes in noise levels for receptors close to the railway tracks would be as follows:

Number of Significant Impacts Time Noise Noise Increase Period Decrease Slight Moderate Substantial >3 dB 3-5 dB 6-10 dB >10 dB Day 0 0 0 0 (07:00 to 23:00 hrs) Night 0 0 0 0 (23:00 to 07:00 hrs)

Note: Noise changes calculated in terms of the LAeq,16hr for Day and LAeq,8hr for Night

2.27 The above table indicates that the changes to the infrastructure and services will not result in a significant increase in noise levels at any receptors. On this basis there will be no significant impacts.

2.28 A detailed study of the potential maximum noise levels arising from the operation of trains has not been undertaken, as it is considered unlikely that the LAmax,F levels associated with the proposed infrastructure and traffic pattern changes will be any higher than those already experienced at nearby receptors.

Vibration from the Surface Railway 2.29 There are no impacts in this route window.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 9 17 February 2005

Noise from Road Traffic 2.30 When the Crossrail scheme is operational, it will cause only small increases in the 18-hour traffic flow on roads in this route window. The change in LA10,18hr corresponding to this increase in traffic is predicted to be < 1 dB. There are therefore no significant impacts arising from increases in operational traffic as a result of the scheme.

Mitigation and Residual Impacts during Operation

Noise from the Surface Railway 2.31 It can be seen from the assessment that no significant noise impacts have been identified and, as such, no further mitigation has been considered.

2.32 A preliminary assessment has been undertaken to identify the number of residential properties which may be eligible for noise insulation under the Noise Insulation (Railways and Other Guided Transport Systems) Regulations 1996, as a result of operational railway noise from modified or altered works in the vicinity.

2.33 The results of this preliminary eligibility assessment indicate that no properties are expected to be eligible for noise insulation under the Regulations.

Vibration and Groundborne Noise from the Underground Railway 2.34 Not applicable to this route window.

Impacts on Sites Granted Planning Permission 2.35 No extant planning permissions that might be affected by the scheme have been identified in this route window.

ROUTE WINDOW NE2 – FOREST GATE STATION

Overview of Route Window NE2 2.36 The main works in this route window, which is located in LB Newham, comprise platform extensions. The GEML platforms (island platforms two and three and platform one) will be extended westwards by 19 m to 205 m to accommodate 10-car Crossrail trains.

2.37 Platform works will be carried out in conjunction with track realignments and signal work. Overall, the construction works will take approximately 10 months to complete.

2.38 Works will be carried out from within the existing fenced boundary of the railway and include a small area to the south of the station for storage. This worksite will be accessed from Earlham Grove. The works will be serviced by an additional site on former railway land at the eastern end of Manor Park station. A rail-mounted crane will be used for lifting platform materials. All large items of plant will be delivered and removed by rail. Other materials will be delivered by lorries to a loading zone on Forest Lane. Excavated materials will be removed by road.

2.39 The main construction plant to be used at the worksite will include cranes, rail cranes, excavators, piling rigs and mechanical breakers.

2.40 Approximately three lorries in total per day will access the worksites during a six week peak construction period. At other times, the worksite will typically be served by one lorry per day.

2.41 The area around the station comprises a mixture of residential, commercial and light industrial use.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 13 17 February 2005

Baseline 2.42 The baseline noise survey locations and durations are listed in the following table and identified on Drawing No. 1E0415-E1E000-E01-F-00002:

Long-term Medium term Short-Term Location Address (1 week) (24-hours) (3-hours) NE07 138 Forest Lane x

2.43 The works proposed at the station includes, platform extensions on the Crossrail lines and local realignment of track in the vicinity of the platform extensions.

2.44 One 24-hour measurement survey was undertaken in this route window at 138 Forest Lane. The microphone was installed on a small balcony above the front door, overlooking the railway line, which is in a cutting at this location. Forest Lane, a busy road, separates the monitoring location from the tracks. Therefore, the dominant noise source was train movements, however in the absence of train noise the dominant noise source was road traffic. At 138 Forest Lane (NE07), the daytime baseline LAeq,12hr level was 70 dB and the night-time LAeq,8hr level 63 dB. Maximum daytime levels reached up to 101 dB LAmax,F, with night-time LAmax,F levels of up to 87 dB.

Impact Assessment – Temporary Impacts

Impacts during Construction 2.45 Temporary impacts from construction activities are illustrated on Drawing No. 1E0315-E1E00-E01-F-00002

Noise from Surface Activity 2.46 Appendix A provides tables for each route window giving the predicted durations of significant impacts for representative receptors. Each listed receptor is representative of one or more dwellings or other noise-sensitive location. Also included in the tables is an estimate of the numbers of dwellings that may be eligible for temporary re- housing and/or noise insulation. Appendix A should be read in conjunction with both the text below and the Construction Noise Assessment Plans provided in Volume 8 of this Technical Report.

Construction Sites and Works including Onsite Traffic 2.47 The construction programme is scheduled to run for six months and is split into 4 phases. In the vicinity of Forest Gate Station, residential properties along Forest Lane, Forest Street and Earlham Grove will be significantly affected by the proposed daytime and night-time construction activities.

2.48 Forest Gate Community School and the Cherubim & Seraphim Church will also be affected by the proposed daytime construction activities.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 14 17 February 2005

Off Site Road Traffic 2.49 Construction vehicles will only use the highway during the daytime (07:00 to 19:00). At façades overlooking roads used by construction traffic, the existing hourly LA10 during the daytime is predicted to increase by < 1 dB. There are therefore no significant impacts arising from construction traffic.

Vibration from Surface Activity 2.50 The plant likely to be required to construct the Crossrail elements at Forest Gate Station has been reviewed to identify sources, which may produce levels of vibration sufficient to cause adverse comment from the occupants of buildings, or cause damage to buildings.

2.51 The construction information provided by Crossrail indicates that concrete breakers are required during platform works, and during the setup of the construction site; that a wacker plate is required during the set-up of the construction site; and, that a CFA piling rig and tamper are required during platform works.

2.52 No significantly substantial buildings or structures have been identified on the construction worksites that would require significant demolition activities, and therefore it is considered that the plant required to undertake the set-up of the construction worksites will not be sources of significant vibration. Vibration levels due to CFA piling are unlikely to be significant. Vibration levels from the platform works are unlikely to be significant at the nearest potentially sensitive receptors, assuming that the breakers are not vehicle mounted.

2.53 Vibration levels are not expected to exceed the threshold of significance for building damage at any receptor during any of the proposed works.

2.54 The construction activities required at this site are likely to give rise to vibration levels that are below those that correspond to a semantic rating of ‘a low probability of adverse comment’. Due to the temporary nature of such works, and with appropriate mitigation, the impact to occupants of the buildings is not likely to be significant.

2.55 No listed buildings, or receptors that are potentially more sensitive to vibration than residential uses, such as precision laboratories and operating theatres, have been identified that are significantly close to this worksite.

Mitigation and Residual Impacts during Construction

Noise from Surface Activity

Construction Sites and Worksites including Onsite Traffic 2.56 Hoardings 3 m high relative to ground height at the top of the cutting would be provided along the railway boundary in the area of the platform extensions, on both sides of the railway. Compressors, generators and other static plant would be located in noise reducing enclosures. This corresponds to Tier 2 mitigation.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 15 17 February 2005

2.57 In this route window, an estimated 39 properties are expected to be eligible for noise insulation due to construction noise. No properties are eligible for temporary re- housing. With the implementation of these mitigation measures no residential properties would be subject to a significant residual construction noise impact.

Offsite Road Traffic 2.58 There are no impacts in this route window.

Vibration from Surface Activity 2.59 The plant likely to be required to demolish the existing buildings or structures and construct the Crossrail elements at Forest Gate Station has been reviewed to identify sources, which may produce levels of vibration sufficient to cause adverse comment from the occupants of buildings, or cause damage to buildings.

2.60 The construction information provided by Crossrail indicates that concrete breakers are required during platform works, during the demolition of the three retail kiosks for the station extension, and during the setup of the construction site; that a wacker plate is required during the setup of the construction site; and, that a CFA piling rig and tamper are required during platform works.

2.61 No significantly substantial buildings or structures have been identified on the construction worksites that would require significant demolition activities, and therefore it is considered that the plant required to undertake the setup of the construction worksites will not be sources of significant vibration. Vibration levels due to CFA piling are unlikely to be significant. Vibration levels from the platform works are unlikely to be significant at the nearest potentially sensitive receptors, assuming that the breakers are not vehicle mounted. Vibration levels in the region of 1 to 4 mm/s are predicted at the foundations of 66 Woodgrange Road, during the demolition of the three retail kiosks for the station extension.

2.62 Vibration levels are not expected to exceed the threshold of significance for building damage at any receptor during any of the proposed works.

2.63 The construction activities required at this site are likely to give rise to vibration levels that are below those that correspond to a semantic rating of ‘a low probability of adverse comment’. Due to the temporary nature of such works, and with appropriate mitigation, the impact to occupants of the buildings is not likely to be significant.

2.64 No listed buildings, or receptors that are potentially more sensitive to vibration than residential uses, such as precision laboratories and operating theatres, have been identified that are significantly close to these worksites.

Impact Assessment – Permanent Impacts

Impacts during Operation

Noise from the Surface Railway 2.65 Intensification of train flows along the line will result in a maximum noise change that is less than 3 dB during both the day and at night. This is below the significance criterion, hence no impact would occur.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 16 17 February 2005

Vibration from the Surface Railway 2.66 There are no impacts in this route window.

Noise from Road Traffic 2.67 When the Crossrail scheme is operational, it will cause only small increases in the 18 hour traffic flow on roads in this route window. The change in LA10,18hr corresponding to this increase in traffic is predicted to be < 1 dB. There are therefore no significant impacts arising from increases in operational traffic as a result of the scheme.

Mitigation and Residual Impacts during Operation

Noise from the Surface Railway 2.68 There are no significant residual impacts.

Vibration from the Surface Railway 2.69 There are no residential impacts.

Noise from Road Traffic 2.70 There are no significant residual impacts.

Impacts on Sites Granted Planning Permission 2.71 No extant planning permissions that might be affected by the scheme have been identified in this route window.

ROUTE WINDOW NE3 – MANOR PARK STATION

Overview of Route Window NE3 2.72 The main works in this route window, which is located in LB Newham, comprise platform extensions. The GEML platforms (platforms one, two and three) will be extended westwards and eastwards by 22 m to 205 m to accommodate 10-car Crossrail trains. Platform one will be widened and the track that passes to the south of platform one (the ‘Up Independent Goods Loop’) will be removed from Forest Gate to east of Manor Park station. A replacement goods loop will be provided between Goodmayes and Chadwell Heath.

2.73 Platform works will be undertaken in conjunction with track realignments and signal works. The existing footbridge/walkway between platforms one and two/three will be modified with stairs to platform one. Subject to possession planning requirements and excluding final commissioning, the construction works will take approximately one year to complete.

2.74 Works at this site will be carried out from within the existing fenced boundary of the railway and will include a site at the eastern end of Manor Park station. The worksite will be accessible from Station Road. A section of Manor Park Road will be temporarily used to accommodate a mobile crane. Large items of plant and materials will be removed by rail, while others (including excavated materials) will be removed by road.

2.75 The main construction plant to be used at the worksite will include cranes, excavators and mechanical breakers.

2.76 Approximately five lorries in total per day will access the worksites during a peak construction period of two and a half months. At other times, the worksite will typically be served by one lorry per day.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 20 17 February 2005

2.77 The area around the station comprises a mixture of residential, commercial and light industrial use. Given the historical and current operations at the site, it is likely that contaminants will be present.

2.78 The main construction compound will lie in an archaeological priority area and the works will affect an area of local ecological importance. No other environmental features of particular note occur within this route window.

Baseline 2.79 The baseline noise survey locations and durations are listed in the following table and identified on Drawing No. 1E0415-E1E000-E01-F-00003:

2.80 One 24-hour survey monitoring location was selected in this route window to determine the existing noise climate within the vicinity of Manor Park Station. At 22 Durham Road (NE08), the baseline noise level was 66 dB LAeq,12hr during the daytime and 59 dB LAeq,8hr at night, with night-time LAmax,F levels of up to 88 dB. Railway noise was the dominant source at this location.

Impact Assessment – Temporary Impacts

Impacts during Construction 2.81 Temporary impacts from construction activities are illustrated on Drawing No. 1E0315-E1E100-E01-F00002.

Noise from Surface Activity 2.82 Appendix A provides tables for each route window giving the predicted durations of significant impacts for representative receptors. Each listed receptor is representative of one or more dwellings or other noise-sensitive location. Also included in the tables is an estimate of the numbers of dwellings that may be eligible for temporary re- housing and/or noise insulation. Appendix A should be read in conjunction with both the text below and the Construction Noise Assessment Plans provided in Volume 8 of this Technical Report.

Construction Sites and Works including Onsite Traffic 2.83 Close to the Manor Park construction site, around 18 properties are predicted to experience a significant noise impact due to proposed construction activities. Residential properties that may experience significant noise levels during the daytime period comprise numbers 2-36 Durham Road which are close to the location of the proposed platform extension works.

2.84 No work will be carried out during evening periods. However, night-time working may result in significant noise impacts at 4 of the above properties in Durham Road. The period when impact would occur is the 6 weeks when the platform extension works are programmed.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 21 17 February 2005

2.85 No non-residential, noise-sensitive receptors predicted to experience significant construction noise impacts.

Offsite Road Traffic 2.86 Construction vehicles will only use the highway during the daytime (07:00 to 19:00). At façades overlooking roads used by construction traffic, the existing hourly LA10 during the daytime is predicted to increase by < 1 dB. There are therefore no significant impacts arising from construction traffic.

Vibration from Surface Activity 2.87 The plant likely to be required to construct the Crossrail elements at Manor Park Station has been reviewed to identify sources, which may produce levels of vibration sufficient to cause adverse comment from the occupants of buildings, or cause damage to buildings.

2.88 The construction information provided by Crossrail indicates that concrete breakers and a wacker plate are required during the set-up of the construction worksites; and, that a CFA piling rig and concrete breakers are required during platform works.

2.89 No significantly substantial buildings or structures have been identified on the construction worksites that would require significant demolition activities, and therefore it is considered that the plant required to undertake the set-up of the construction worksites will not be sources of significant vibration. Vibration levels due to CFA piling are unlikely to be significant. Vibration levels from the platform works are unlikely to be significant at the nearest potentially sensitive receptors, assuming that the breakers are not vehicle mounted.

2.90 Vibration levels are not expected to exceed the threshold of significance for building damage at any receptor during any of the proposed works.

2.91 The construction activities required at this site are likely to give rise to vibration levels that are below those that correspond to a semantic rating of ‘a low probability of adverse comment’. Due to the temporary nature of such works, and with appropriate mitigation, the impact to occupants of the buildings is not likely to be significant.

2.92 No listed buildings, or receptors that are potentially more sensitive to vibration than residential uses, such as precision laboratories and operating theatres, have been identified that are significantly close to this worksite.

Mitigation and Residual Impacts during Construction

Noise from Surface Activity

Construction Sites and Worksites including Onsite Traffic 2.93 Hoardings 2.4 m high would be provided around the construction compound and along the southern railway boundary in the vicinity of the platform extension work. A 3.6 m high hoarding would also be provided along the northern railway boundary in the same area. This corresponds to Tier 2 mitigation.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 22 17 February 2005

2.94 In this route window, an estimated 14 properties are expected to be eligible for noise insulation due to construction noise. No dwellings are expected to be eligible for temporary re-housing. With the implementation of these mitigation measures only four properties, in Durham Road, would be subject to a significant residual construction noise impact.

Offsite Road Traffic 2.95 There are no significant residual impacts.

Vibration from Surface Activity 2.96 There are no significant residual impacts.

Impact Assessment – Permanent Impacts

Impacts during Operation

Noise from the Surface Railway 2.97 Intensification of train flows along the line will result in a maximum noise change that is less than 3 dB during both the day and at night. This is below the significance criterion, hence no impact would occur.

Vibration from the Surface Railway 2.98 There are no impacts in this route window.

Noise from Road Traffic 2.99 When the Crossrail scheme is operational, it will cause only small increases in the 18-hour traffic flow on roads in this route window. The change in LA10,18hr corresponding to this increase in traffic is predicted to be < 1 dB. There are therefore no significant impacts arising from increases in operational traffic as a result of the scheme.

ROUTE WINDOW NE4 – ILFORD STATION

Overview of Route Window NE4 2.104 This route window lies in LB Newham and LB Redbridge. The works include the provision of a new station building accessible from Cranbrook Road, York Place and Ilford Hill, and temporary sidings for the construction and fit out of the central section tunnels, on derelict land at the Aldersbrook sidings site to the west of the North Circular Road. The works to Ilford station will be undertaken within a railway cutting.

2.105 There are a number of shops in the locality of Ilford station, primarily located along Cranbrook Road, with a large shopping centre to the east of the station. To the north there are largely residential areas along York Road. To the south, commercial development is concentrated in a number of large office blocks along Ilford Hill. To the west, the rail corridor passes beneath the North Circular Road, with Ilford Golf Course and City of London Cemetery beyond.

2.106 The Aldersbrook sidings site contains a disused railway training school and a number of derelict buildings, in addition to regenerating scrub. Alders Brook runs from between the City of London Cemetery and the Ilford Golf Course, along the western and southern boundary of the site. Residential areas are located to the south and west of the Aldersbrook sidings site. These established neighbourhoods continue along the southern side of the GEML towards Manor Park station, and the extensive City of London Cemetery lies to the northwest adjoining the railway line.

Baseline 2.107 The baseline noise survey location and duration is listed in the following table and identified on Drawing No. 1E0415-E1E000-E01-F-00004:

2.108 A 24-hour measurement was undertaken at 55 York Road, the location of a doctor's surgery (RB01). The baseline noise level was 68 dB LAeq,12hr during the daytime period and 61 dB LAeq,8hr at night, with night-time LAmax,F levels of up to 86 dB. The dominant noise source was train movements, however a continuous humming was also audible from a power generator located in a Balfour Beatty depot nearby.

Impact Assessment – Temporary Impacts

Impacts during Construction 2.109 Temporary impacts from construction activities are illustrated on Drawing No. 1E0315-E1E00-E01-F-00004.

Noise from Surface Activity 2.110 Appendix A provides tables for each route window giving the predicted durations of significant impacts for representative receptors. Each listed receptor is representative of one or more dwellings or other noise-sensitive location. Also included in the tables is an estimate of the numbers of dwellings that may be eligible for temporary re- housing and/or noise insulation. Appendix A should be read in conjunction with both the text below and the Construction Noise Assessment Plans provided in Volume 8 of this Technical Report.

Construction Sites and Works including Onsite Traffic

Ilford Station Worksite 2.111 During the construction works at Ilford station worksite, a number of residential properties will be adversely impacted by noise from the construction site. The affected properties are mainly concentrated in York Mews, York Road, Cranbrook Road and the Ilford Hill area.

2.112 One public house is predicted to be adversely impacted; at 71 Ilford Hill. In addition, impacted non-residential properties include two medical surgeries on York Road (27 and 55 York Road) and Carmel College at 9 to 17 Cranbrook Road.

2.113 Construction activities that will generate noise are site establishment works, demolition of platform structures, platform extensions, foundation works, concourse construction and the erection of the station building.

2.114 Construction works are programmed to last for six months. During this time, there will be daytime (07:00 to 19:00), evening (19:00 to 23:00), night-time (23:00 to 07:00) and weekend activities.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 27 17 February 2005

Aldersbrook Sidings Worksite 2.115 No noise impacts are expected to occur due to construction works programmed at Aldersbrook Sidings.

Offsite Road Traffic 2.116 Construction vehicles will only use the highway during the daytime (07:00 to 19:00). At façades overlooking roads used by construction traffic, the existing hourly LA10 during the daytime is predicted to increase by < 1 dB. There are therefore no significant impacts arising from construction traffic.

Vibration from Surface Activity

Aldersbrook Sidings Worksite 2.117 The plant likely to be required to construct the Crossrail elements at Aldersbrook Sidings Worksite has been reviewed to identify sources, which may produce levels of vibration sufficient to cause adverse comment from the occupants of buildings, or cause damage to buildings.

2.118 The construction information provided by Crossrail indicates that a tamper and a wacker plate are required during track works; and that a vibratory piling rig will be required. Information provided by Crossrail indicates that retaining walls may be required just inside the fence line. It is assumed that this is the requirement for the vibratory piling rig, and the fence line has been assumed as the location of this source. The same report also refers to demolition of buildings on the old College of Railway Technology and garages at the end of Alexander Road. For the vibration assessment the plant used for demolition has been assumed to be hydraulic breakers fitted to excavators.

2.119 Vibration levels in the region of 0.5 to 2.5 mm/s are predicted to occur at 1021 Romford Road (which is not a residential building) during demolition of the old College of Railway Technology, and 1 to 4 mm/s at 40 Colchester Avenue, which is the closest residential building to the demolition of the garages. The assessment assumes vehicle-mounted breakers. Vibration levels will be significantly less if hand- held breakers are used. Vibration levels in the region of 1 to 6 mm/s are predicted to occur at 25 and 26 Gloucester Road, which are the closest residential buildings to the proposed track-works, during vibratory piling.

2.120 Vibration levels may exceed the threshold of significance for building damage at 25 and 26 Gloucester Road if vibratory piling is required at the site boundary closest to these receptors. Vibration levels are not expected to exceed the threshold of significance for building damage at any receptor during the remainder of the proposed works.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 28 17 February 2005

2.121 The vibratory piling activities required at this site may give rise to vibration levels that correspond to a semantic rating of ‘Adverse comment probable’ at 25 and 26 Gloucester Road if vibratory piling is required at the site boundary closest to these receptors, for days that works occur throughout the majority of a working day at this location. The remainder of the construction activities are likely to give rise to vibration levels that are below those that correspond to a semantic rating of ‘a low probability of adverse comment’. Due to the temporary nature of such works, and with appropriate mitigation, the impact to occupants of the buildings is not likely to be significant.

2.122 No listed buildings, or receptors that are potentially more sensitive to vibration than residential uses, such as precision laboratories and operating theatres, have been identified that are significantly close to this worksite.

Ilford Station Worksite 2.123 The plant likely to be required to construct the Crossrail elements for Ilford Station Worksite has been reviewed to identify sources, which may produce levels of vibration sufficient to cause adverse comment from the occupants of buildings, or cause damage to buildings.

2.124 The construction information provided by Crossrail indicates that breakers are required to demolish the station, the platforms, and a number of buildings around the site; breakers and a wacker plate are required during site set-up; and breakers and a CFA piling rig is required during platform works. It is considered that, with the exception of building demolition, the plant required to undertake the set-up of the construction site will not be sources of significant vibration. Vibration levels due to CFA piling are unlikely to be significant. Vibration levels from the platform construction works are unlikely to be significant at the nearest potentially sensitive receptors, assuming that the breakers are not vehicle mounted.

2.125 It is noted that 71 Ilford Hill, a public house due south of the station, is on the London Borough of Redbridge’s list of buildings with special architectural or historical interest. Mapping indicates that 31 Cranbrook Road and 9 to 17 Cranbrook Road are attached or contiguous to buildings that require demolition. Vibration levels of concern could occur due to the structural continuity between buildings.

2.126 Vibration levels are predicted to be in the region of 2 to 10 mm/s at 55 York Road, a doctor’s surgery, during demolition of the secondary ticket hall; 0.5 to 2.5 mm/s and 0.5 to 3 mm/s, at the closest buildings on York Road to the worksite and at 18 to 26 Cranbrook Road, respectively, during demolition of the northern platform and main station building; 2 to 10 mm/s and 0.5 to 2.5 mm/s, at 9 to 17 Cranbrook Road and 71 Ilford Hill, respectively, during demolition of the northern platform and main station building; and 4 to 15 mm/s at 71 Ilford Hill during demolition of the two taxi cab offices.

2.127 The threshold of significance for building damage may be exceeded at 55 York Road, 9 to 17 Cranbrook Road, and 71 Ilford Hill, when demolition activities are undertaken of adjacent buildings, although the threshold of significance is unlikely to be exceeded at any of the surrounding buildings during the remainder of construction activities.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 29 17 February 2005

2.128 With the exception of the demolition works, the construction activities required at this site are likely to give rise to vibration levels that are below those that correspond to a semantic rating of ‘a low probability of adverse comment’. Levels may occur that correspond to ‘adverse comment possible’ at 55 York Road, 9 to 17 Cranbrook Road, and 71 Ilford Hill, for a limited period during demolition of adjacent buildings. Due to the temporary nature of such works, and with appropriate mitigation, the impact to occupants of the buildings is not likely to be significant.

2.129 No listed buildings, or receptors that are potentially more sensitive to vibration than residential uses, such as precision laboratories and operating theatres, have been identified that are significantly close to this worksite.

Mitigation and Residual Impacts during Construction

Noise from Surface Activity

Construction Sites and Works including Onsite Traffic 2.130 Hoardings 3.6m high would be provided around the worksites. This corresponds to Tier 2 mitigation.

Ilford Station Worksite 2.131 In this route window, an estimated 48 properties may be eligible for noise insulation due to construction noise. Included in this number are the residents of approximately 18 dwellings may be eligible for temporary re-housing for a period. With the implementation of these mitigation measures, no residential properties within the vicinity of Ilford Station would be subject to significant residual construction noise impacts. Two surgeries and an educational facility would be impacted. There exists a planning application for a guest house which would also be impacted if its development was to proceed.

Aldersbrook Sidings Worksite 2.132 No properties are likely to qualify for noise insulation from the works or temporary re- housing and there would be no residual noise impacts.

Offsite Road Traffic 2.133 There are no significant residual impacts.

Vibration from Surface Activity 2.134 Vibration mitigation will be required during demolition activities at this site, to mitigate potential impacts on adjacent buildings. Where there are buildings that are attached or contiguous to buildings that are proposed for demolition, the attached buildings should be unattached, as far as possible using non-vibratory techniques, such as diamond sawing before demolition commences, and should continue as it progresses. Additionally, detailed assessment should be undertaken prior to commencement of works to inform the selection of specific items of plant and working methods. An appropriate continuous vibration-monitoring regime should be adopted during demolition works allow monitoring of levels and cessation of activity should levels exceed relevant limits.

ROUTE WINDOW NE5 – SEVEN KINGS STATION

Overview of Route Window NE5 2.142 Within this route window, two GEML platforms (island platforms two, three and platform four) will be extended westwards by 18 m to 205 m to accommodate 10-car Crossrail trains. Platform works will be carried out in conjunction with track realignments, OHLE and signal works. Overall, the construction works will take approximately five months to complete.

2.143 The works at this station will be carried out from the existing fenced boundary of the railway on platforms four and two/three. The worksite will be located to the northwest of the existing station within the grounds of Canon Palmer Catholic School. It will be accessible from Lombard Avenue, off Aldborough Road South. Large plant and materials for platform construction will be delivered and removed by rail. Other materials and excavated materials will be removed by road.

2.144 The main construction plant to be used at the worksite will include cranes, rail cranes, excavators, piling rigs and mechanical breakers.

2.145 Generally, the worksite will be served by one lorry per day. Approximately two lorries in total per day will access the worksites during a peak construction period that will last a month.

2.146 The area around the station comprises predominantly railway land/operations and commercial premises.

Baseline 2.147 One measurement survey was undertaken in route window NE5, the baseline noise survey location and its duration is listed in the following table and identified on Drawing No. 1E0415-E1E000-E01-F-00005:

2.148 At 22 Lombard Avenue (RB02), near Seven Kings Station, the baseline noise level was 78 dB LAeq,12hr during the daytime and 68 dB LAeq,8hr at night, with night-time LAmax,F levels of up to 100 dB. The source dominating the noise environment was the railway.

Impact Assessment – Temporary Impacts

Impacts during Construction 2.149 Temporary impacts from construction activities are illustrated on Drawing No. 1E0315-E1E00-E01-F00005

Noise from Surface Activity 2.150 Appendix A provides tables for each route window giving the predicted durations of significant impacts for representative receptors. Each listed receptor is representative of one or more dwellings or other noise-sensitive location. Also included in the tables is an estimate of the numbers of dwellings that may be eligible for temporary re- housing and/or noise insulation. Appendix A should be read in conjunction with both the text below and the Construction Noise Assessment Plans provided in Volume 8 of this Technical Report.

Construction Sites and Works including Onsite Traffic 2.151 The construction programme is scheduled to run for approximately 5 months. Activities that are likely to cause significant impacts are the platform extension works.

2.152 In the vicinity of Seven Kings Station, there will be a small number of properties that are affected by construction noise. Some properties in Lombard Avenue are expected to experience significant daytime noise impacts. High noise levels are also predicted at Canon Palmer Catholic School, neighbouring the site, but as these are only from night-time works, they would not give rise to a significant impact as the school would not be in use at night.

Off Site Road Traffic 2.153 Construction vehicles will only use the highway during the daytime (07:00 to 19:00). At façades overlooking roads used by construction traffic, the existing hourly LA10 during the daytime is predicted to increase by < 1 dB. There are therefore no significant impacts arising from construction traffic.

Vibration from Surface Activity 2.154 The plant likely to be required to construct the Crossrail elements at Seven Kings Station has been reviewed to identify sources, which may produce levels of vibration sufficient to cause adverse comment from the occupants of buildings, or cause damage to buildings.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 35 17 February 2005

2.155 The construction information provided by Crossrail indicates that concrete breakers and a wacker plate are required during the set-up of the construction worksite; and that concrete breakers, a wacker plate and a CFA piling rig are required during platform works.

2.156 No significantly substantial buildings or structures have been identified on the construction site that would require significant demolition activities, and therefore it is considered that the plant required to undertake the set-up of the construction site will not be sources of significant vibration. Vibration levels due to CFA piling are unlikely to be significant. Vibration levels from the platform works are unlikely to be significant at the nearest potentially sensitive receptors, assuming that the breakers are not vehicle mounted.

2.157 Vibration levels are not expected to exceed the threshold of significance for building damage at any receptor during any of the proposed works.

2.158 The construction activities required at this site are likely to give rise to vibration levels that are below those that correspond to a semantic rating of ‘a low probability of adverse comment’. Due to the temporary nature of such works, and with appropriate mitigation, the impact to occupants of the buildings is not likely to be significant.

2.159 No listed buildings, or receptors that are potentially more sensitive to vibration than residential uses, such as precision laboratories and operating theatres, have been identified that are significantly close to this worksite.

Mitigation and Residual Impacts during Construction

Noise from Surface Activity

Construction Sites and Worksites including Onsite Traffic 2.160 Hoardings of a minimum height of 3.6 m would be provided along the northern boundary of the platform extension working area and 2.4 m around the eastern part of the station platform extension working areas and the site compound. Compressors and generators operated during the night-time period would be located in noise reducing enclosures. This corresponds to Tier 2 mitigation.

2.161 In this route window, an estimated 5 residential properties may be eligible for noise insulation due to construction noise. No dwellings are expected to be eligible for temporary re-housing, With the implementation of these mitigation measures no residential properties would be subject to a significant residual construction noise impact.

ROUTE WINDOW NE6 – GOODMAYES STATION

Overview of Route Window NE6 2.171 The main works in this route window, which is located in LB Redbridge, comprise platform extensions at Goodmayes station and the construction of the Chadwell Heath freight loop.

2.172 The platform extensions comprise the eastward extension of two GEML platforms (platforms two, three and four) by 16 m to 205 m to accommodate 10-car Crossrail trains. The construction works at Goodmayes station will take approximately five months to complete. The construction of the Chadwell Heath freight loop will partially overlap these works and will occur over a four-month period. The construction works for the loop spans both this route window and Route Window NE7.

2.173 Works at the Goodmayes station worksite will be carried out from within the existing fenced boundary of the railway on platforms four and two/three. The worksite servicing activities on the site will be located on redundant railway land to the northeast of the existing station next to platform one. Access to the site will occur from the High Road via existing service roads alongside Goodmayes Retail Park and the Superstore car park. Large items of plant and materials for the construction works will be delivered and removed by rail. Other materials, including excavated materials will be delivered by road.

2.174 The main construction plant to be used at the worksite will include cranes, excavators, piling rigs and mechanical breakers. Approximately two lorries in total per day will access the worksites during a peak construction period of approximately a month. At other times, the worksite will typically be served by one lorry per day.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 39 17 February 2005

2.175 The currently disused Goodmayes to Chadwell Heath freight loop will be reinstated to replace the goods loop at Manor Park. This work will include the removal of the existing redundant loop track. The trackbed will need to be lowered at the bridge at both Goodmayes and Chadwell Heath stations. Associated signalling works will take place, in addition to the installation of the crossover at the western end of the station. OHLE and signalling will then be installed. A new drainage system and a walkway will be installed adjacent to the tracks.

2.176 This track work will be carried out from within the existing fenced boundary of the railway to the south of the existing track. The main worksite will be located at the eastern end of the station with another to the south of the existing tracks at Goodmayes station. Access to the main worksite will be from Goodmayes Road via Kinfauns Road and Express Drive. Large items of plant and materials, including excavated materials for the works will be delivered and removed by road. Generally, the Express Drive southern worksite will be served by one lorry per day, including during the two-month peak construction period.

2.177 The area around the station comprises a densely built-up urban area intersected by the existing railway. There are residential neighbourhoods to the south, east and west of the station, and an extensive retail park to the north.

Baseline 2.178 One 24-hour monitoring location has been selected within this route window, the baseline noise survey location and duration is listed in the following table and identified on Drawing No. 1E0302-G0G00-E01-F-00006:

Long-term Medium term Short-Term Location Address (1 week) (24-hours) (3-hours) RB03 58 Fenman Gardens x

2.179 A medium-term, 24-hour measurement survey was completed at Fenman Gardens (RB03) to the south of Goodmayes Station. The daytime LAeq,12hr baseline level measured at this location was 72 dB, falling to an LAeq,8hr of 65 dB during the night- time period. The day and night LAmax,F ranged up to 94 dB, in both periods. The dominant noise source was train movements, although these were infrequent. Other noise sources included distant road traffic and aircraft overhead, but the area was reasonably quiet between train pass-bys.

Impact Assessment – Temporary Impacts

Impacts during Construction 2.180 Temporary impacts from construction activities are illustrated on Drawing No. 1E0315-E1E00-E01-F-00006.

Noise from Surface Activity 2.181 Appendix A provides tables for each route window giving the predicted durations of significant impacts for representative receptors. Each listed receptor is representative of one or more dwellings or other noise-sensitive location. Also included in the tables is an estimate of the numbers of dwellings that may be eligible for temporary re- housing and/or noise insulation. Appendix A should be read in conjunction with both the text below and the Construction Noise Assessment Plans provided in Volume 8 of this Technical Report.

Construction Sites and Works including Onsite Traffic

Goodmayes Station Worksite 2.182 The construction programme is scheduled to run for approximately six months. Activities that are likely to cause significant impacts are associated with the platform extension works.

2.183 No noise impacts are expected to occur due to construction works programmed at Goodmayes Station.

Chadwell Heath Freight Loop Worksite West 2.184 The construction programme is scheduled to run for four months. Activities that are likely to cause significant impacts include track works.

2.185 In the vicinity of the Chadwell Heath Freight Loop, there will be two groups of properties that are affected by construction noise. Properties in Express Drive and Fenman Gardens are expected to experience significant noise impacts and these are for the daytime period only.

Offsite Road Traffic 2.186 Construction vehicles will only use the highway during the daytime (07:00 to 19:00). At façades overlooking roads used by construction traffic, the existing hourly LA10 during the daytime is predicted to increase by < 1 dB. There are therefore no significant impacts arising from construction traffic.

Vibration from Surface Activity 2.187 The plant likely to be required to construct the Crossrail elements at Goodmayes Station has been reviewed to identify sources, which may produce levels of vibration sufficient to cause adverse comment from the occupants of buildings, or cause damage to buildings.

2.188 The construction information provided by Crossrail indicates that concrete breakers and a wacker plate are required during the set-up of the construction worksite; and that concrete breakers and a CFA piling rig are required during platform works.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 41 17 February 2005

2.189 No significantly substantial buildings or structures have been identified on the construction site that would require significant demolition activities, and therefore it is considered that the plant required to undertake the set-up of the construction site will not be sources of significant vibration. Vibration levels due to CFA piling are unlikely to be significant. Vibration levels from the platform works are unlikely to be significant at the nearest potentially sensitive receptors, assuming that the breakers are not vehicle mounted.

2.190 Vibration levels are not expected to exceed the threshold of significance for building damage at any receptor during any of the proposed works.

2.191 The construction activities required at this site are likely to give rise to vibration levels that are below those that correspond to a semantic rating of ‘a low probability of adverse comment’. Due to the temporary nature of such works, and with appropriate mitigation, the impact to occupants of the buildings is not likely to be significant.

2.192 No listed buildings, or receptors that are potentially more sensitive to vibration than residential uses, such as precision laboratories and operating theatres, have been identified that are significantly close to this worksite.

Mitigation and Residual Impacts during Construction

Noise from Surface Activity

Construction Sites and Worksites including Onsite Traffic 2.193 2.4 m high hoardings would be provided along three sections to the north of the railway. 3.6 m high hoardings would be provided to the south along the boundary with properties in Fenman Gardens, with lengths of 2.4 m hoardings to the west and east. This corresponds to Tier 2 mitigation.

2.194 In this route window, an estimated 43 properties, associated with works for the Chadwell Heath Freight Loop, may be eligible for noise insulation due to construction noise. No dwellings are expected to be eligible for temporary re-housing. With the implementation of these mitigation measures no properties would be subject to a significant residual construction noise impact.

Offsite Road Traffic 2.195 There are no significant residual impacts.

Vibration from Surface Activity 2.196 There are no significant residual impacts.

Impacts during Operation

Noise from the Surface Railway

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 42 17 February 2005

2.197 Intensification of train flows along the line will result in a maximum noise change that is less than 3 dB during both the day and at night. This is below the significance criterion, hence no impact would occur.

Vibration from the Surface Railway 2.198 There are no impacts in this route window.

Noise from Road Traffic 2.199 When the Crossrail scheme is operational, it will cause only small increases in the 18-hour traffic flow on most roads in this route window. The change in LA10,18hr corresponding to this increase in traffic is predicted to be < 1 dB except along parts of Goodmayes Road. At façades overlooking the sections of Goodmayes Road between Goodmayes Avenue and the Car Park and between Ashgrove Road and the Car Park, the change in LA10,18hr corresponding to the increase in traffic is predicted to be between 1 and 2 dB. There are therefore no significant impacts arising from increases in operational traffic as a result of the scheme.

ROUTE WINDOW NE7 – CHADWELL HEATH STATION

Overview of Route Window NE7 2.204 This route window lies within LB Redbridge and LB Barking and Dagenham. The main works comprise platform extensions to Chadwell Heath station and the construction of the Chadwell Heath freight loop.

2.205 The GEML platforms two, three and four will be extended westwards by 16 m to 205 m to accommodate 10-car Crossrail trains. New platform furniture and lighting will be provided and minor station refurbishment works will be carried out.

2.206 Works at the station will be carried out from within the existing fenced boundary of the railway on platforms two/three and four. The worksite servicing activities on the site will be located within an existing car park off Valance Avenue. For the platform extension works, plant and materials will be brought from the Chadwell Heath freight loop worksite to the east of the station by rail. Access to the site will occur from Valance Avenue.

2.207 The currently disused single line to the south of the main lines will be reinstated to replace the goods loop at Manor Park. These works will include the removal of the existing redundant track. Once trackbeds are prepared and the new track is laid, OHLE and signalling will be installed. A new drainage system and a walkway will also be installed adjacent to the tracks.

2.208 The freight loop track work will be carried out from within the existing fenced boundary of the railway to the south of the existing track. The main worksite will be located at the eastern end of the station; a second will be located south of the existing tracks at Goodmayes station. Access to the main worksite will be from Valence Avenue. Large items of plant and materials, including excavated materials for the works will be delivered and removed by road.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 46 17 February 2005

2.209 The main construction plant to be used at the worksite will include cranes, rail cranes, excavators, piling rigs and mechanical breakers. Generally, the freight loop worksite will be served by one lorry per day, including during the eight- week peak construction period. The Chadwell Heath Station Worksite will be served by two lorries per day during the five-week peak construction period and by one per day at other times.

2.210 The area around Chadwell Heath station comprises a heavily built-up residential area to the north of the railway line, with a more open urban landscape to the south, where depots and warehousing are located.

Baseline 2.211 Three 24-hour baseline noise survey locations were selected in this route window, the locations and durations are listed in the following table and identified on Drawing No. 1E0415-E1E000-E01-F-00007:

Long-term Medium term Short-Term Location Address (1 week) (24-hours) (3-hours) RB04 52 Overton Drive x BD01 2 Heath Road x BD02 30 Burlington Gardens x

2.212 Three 24-hour measurement locations were selected in this route window, all on the north side of the railway. These were 52 Overton Drive (RB04) which is close to Chadwell Heath Station, 2 Heath Road (BD01) and 30 Burlington Gardens (BD02). Measured baseline noise levels were in the range 64 dB to 73 dB LAeq,12hr during the daytime and 58 dB to 66 dB LAeq,8hr at night, with night-time LAmax,F levels between 86 dB and 94 dB. The dominant noise source at all three locations was that from train movements, with the highest noise levels measured at BD01 and the lowest at BD02.

Construction Sites and Works including Onsite Traffic

Chadwell Heath Freight Loop 2.215 The construction programme is scheduled to run for 4 months. Activities that are likely to cause significant impacts comprise modifications to the tracks and associated works.

2.216 In the vicinity of the Chadwell Heath Freight Loop works, a small number of residential properties located in Griffith Close are expected to experience significant noise impacts. The impacts would only arise from weekend construction activities.

Chadwell Heath Station 2.217 The construction programme is scheduled to run for 3 months. Activities that are likely to cause significant impacts include station construction works.

2.218 In the vicinity of Chadwell Heath Station, there will be a number of properties that are affected by construction noise. In particular, properties in Overton Drive and Armstrong Close are expected to experience significant daytime noise impacts. No noise impacts for non-residential, noise-sensitive properties have been identified within this route window.

Offsite Road Traffic 2.219 Construction vehicles will only use the highway during the daytime (07:00 to 19:00). At façades overlooking roads used by construction traffic, the existing hourly LA10 during the daytime is predicted to increase by < 1 dB. There are therefore no significant impacts arising from construction traffic.

Vibration from Surface Activity 2.220 The plant likely to be required to construct the Crossrail elements at Chadwell Heath Station has been reviewed to identify sources, which may produce levels of vibration sufficient to cause adverse comment from the occupants of buildings, or cause damage to buildings.

2.221 The construction information provided by Crossrail indicates that concrete breakers and a wacker plate are required during the set-up of the construction worksite; and that concrete breakers and a CFA piling rig are required during platform works.

2.222 No significantly substantial buildings or structures have been identified on the construction site that would require significant demolition activities, and therefore it is considered that the plant required to undertake the set-up of the construction site will not be sources of significant vibration.

Due to the temporary nature of such works, and with appropriate mitigation, the impact to occupants of the buildings is not likely to be significant.

No listed buildings, or receptors that are potentially more sensitive to vibration than residential uses, such as precision laboratories and operating theatres, have been identified that are significantly close to this worksite.

Mitigation and Residual Impacts during Construction

Noise from Surface Activity

Construction Sites and Worksites including Onsite Traffic 2.225 Standard 2.4 m high hoardings would be provided to the north and south of the railway, along much of its length, where works are to be carried out as well as around the site compounds and worksites. 3.6 m high hoardings would be required along the railway boundaries in the vicinity of the platform extensions. This corresponds to Tier 2 mitigation.

2.226 In this route window, an estimated 4 properties may be eligible for noise insulation due to construction noise. No dwellings are expected to be eligible for temporary re- housing. With the implementation of these mitigation measures, 9 properties would be subject to a significant residual construction noise impact.

Offsite Road Traffic 2.227 There are no significant residual impacts.

Vibration from Surface Activity 2.228 There are no significant residual impacts.

Impact Assessment – Permanent Impacts

Impacts during Operation

Noise from the Surface Railway 2.229 In this Route Window there are proposed changes to the railway (permanent way) infrastructure in the vicinity of the existing Chadwell Heath Station. A freight loop will be constructed in place of an existing headshunt, which currently services the Chadwell Heath sidings. The loop will be located to the south of the main railway corridor and is needed to replace the system being removed at Manor Park, allowing freight trains to recess while faster trains pass. A Level 3 (detailed assessment) has been carried out for this area.

2.230 There will also be a change in the composition of railway traffic along the Great Eastern corridor with the implementation of Crossrail. The predicted noise changes attributable to the infrastructure and forecast railway traffic changes in the vicinity of the sidings have been calculated taking account of the new alignments, precise mix of expected rail vehicles and the operating speeds of the various train types.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 49 17 February 2005

2.231 The resulting changes in noise levels for receptors close to the railway tracks would be as follows:

Time Number of Significant Impacts Period Noise Noise Increase Decrease Slight Moderate Substantial >3 dB 3-5 dB 6-10 dB >10 dB Day 0 0 0 0 (07:00 to 23:00 hrs) Night 0 0 0 0 (23:00 to 07:00 hrs)

Note: Noise changes calculated in terms of the LAeq,16hr for Day and LAeq,8hr for Night

2.232 The above table indicates that the changes to the infrastructure and services will not result in an increase in noise levels. On this basis there will be no significant impacts. The noise generated by the trains travelling along the Great Eastern Main and Electric Lines dominates the noise climate in this area. The introduction of the freight loop does not introduce any significant impacts at nearby receptors primarily due to the lower numbers of trains using the loop compared to overall number of trains on the Great Eastern Lines.

2.233 A detailed study of the potential maximum noise levels arising from the operation of trains has not been undertaken, as it is considered unlikely that the LAmax,F levels associated with the proposed infrastructure and traffic pattern changes will be any higher than those already experienced at nearby receptors.

Vibration from the Surface Railway 2.234 The reinstatement of the Freight Loop at a distance of 10.4 m from the near rail to the nearest dwelling in Faulkner Close will potentially cause an increase in vibration dose value of 70%, a significant increase, for 7 properties.

Noise from Road Traffic 2.235 When the Crossrail scheme is operational, it will cause only small increases in the 18-hour traffic flow on roads in this route window. The change in LA10,18hr corresponding to this increase in traffic is predicted to be < 1 dB. There are therefore no significant impacts arising from increases in operational traffic as a result of the scheme.

Vibration and Groundborne Noise from the Underground Railway 2.236 Not applicable to this route window.

Mitigation and Residual Impacts during Operation

Noise from the Surface Railway 2.237 It can be seen from the assessment that no significant noise impacts have been identified and, as such, no further mitigation has been considered.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 50 17 February 2005

2.238 A preliminary assessment has been undertaken to identify the number of residential properties which may be eligible for noise insulation under the Noise Insulation (Railways and Other Guided Transport Systems) Regulations 1996, as a result of operational railway noise from modified or altered works in the vicinity.

2.239 The results of this preliminary eligibility assessment indicate that no properties are expected to be eligible for noise insulation under the Regulations.

Vibration from the Surface Railway 2.240 The increase can be fully mitigated by the installation of a reslient underballast mat below the track of the freight loop for a distance of 150 m. There would then be no remaining residual impacts.

Noise from Road Traffic 2.241 There are no significant residual impacts.

Impacts on Sites Granted Planning Permission 2.242 No extant planning permissions that might be affected by the scheme have been identified in this route window.

ROUTE WINDOW NE8 – ROMFORD DEPOT (WEST)

Overview of Route Window NE8 2.243 The route alignment in this route window passes through LB Barking and Dagenham and LB Havering. The main works in this route window comprise the construction of a rail underpass in order to reduce conflicting movements between trains on the GEML and those moving to and from a new Romford depot. This will also require works to Jutsums Lane bridge.

2.244 The route window is located between Whalebone Lane South, Chadwell Heath in the west and Sheringham Avenue, Romford in the east. The area to the north of the GEML is dominated by the Westland’s Playing Field. West Ham United Football Club (FC) training ground and residential areas, while residential and industrial works are located to the south. Crowlands Heath Golf Course is also located to the south of the GEML.

2.245 Baseline noise levels within this route window are dominated by railway noise and are relatively high.

Baseline 2.246 The baseline noise survey locations and durations are listed in the following table and identified on Drawing No. 1E0415-E1E000-E01-F-00008:

2.247 Short-term daytime measurement results of 57 dB, 60 dB and 52 dB LAeq,3hr were obtained at Westland playing fields (Residential) (HA06), Westland Playing Fields (Railway) (HA07) and Jutsums Recreation Ground (HA09), respectively. Free-field LAmax,F levels reached up to up to 81 dB at HA06, 78 dB at HA07 and 67 dB at HA09.

2.248 Medium-term daytime measurement results of 75 dB, 55 dB and 68 dB LAeq,12hr were obtained at 218 Crow Lane (to the rear of Vignoles Road) (HA04), 218 Crow Lane (HA05) and 91 Jutsums Lane (HA08), respectively. At the three locations, the night- time LAeq,12hr fell by 13 dB, 2 dB and 4 dB, respectively compared with the day-time works. The maximum night-time LAmax,F levels were found to between 83 dB and 99 dB.

2.249 The monitoring equipment at HA04 was positioned on the boundary of Ahern Waste Management land, approximately 4m from residential properties on Vignoles Road, in a free-field position. At this position the dominant noise source during the day was industrial activity from the Ahern workshop, while railway noise was the dominant source at night.

2.250 Numbers 218 to 228 Crow Lane (HA05) are bungalows that have been converted into two storey office buildings. A combination of road and railway noise dominated the noise climate at this location.

2.251 Long-term measurement surveys were undertaken at West Ham Training Ground (BD03) and Ainsley Avenue (HA10). At BD03, the microphone was located on the rear façade of the sports hall, at approximately 2.5 m high, with a clear line of sight onto the railway line. Hence, railway movements were the principle influence on the noise environment. The daytime LAeq,12hr level was 74 dB, with night-time LAeq,8hr levels falling to 69 dB and night-time LAmax,F levels of up to 96 dB.

2.252 The daytime LAeq,12hr noise level at 11a Ainsley Avenue (HA10) was 70 dB, with a night-time LAeq,8hr noise level of 66 dB and LAmax,F levels ranging up to 95 dB. The principle noise source at this location was railway noise, with the tracks running on a 3m high embankment, close to the end of the rear garden.

Impact Assessment – Temporary Impacts

Impacts during Construction 2.253 Temporary impacts from construction activities are illustrated on Drawing No. 1E0315-E1E00-E01-F-00008

Noise from Surface Activity 2.254 Appendix A provides tables for each route window giving the predicted durations of significant impacts for representative receptors. Each listed receptor is representative of one or more dwellings or other noise-sensitive location. Also included in the tables is an estimate of the numbers of dwellings that may be eligible for temporary re- housing and/or noise insulation. Appendix A should be read in conjunction with both the text below and the Construction Noise Assessment Plans provided in Volume 8 of this Technical Report.

Construction Sites and Works including Onsite Traffic 2.255 The construction programme is scheduled to run for just over two years and is split into 14 phases. Activities that are likely to cause significant impacts include building and track works for the depot approach, structural works to the station, mainline dive under enabling works, structural works to Jutsums Lane, sidings and track works; and enabling, construction and track works for the maintenance depot.

2.256 To the west of the Romford Depot, there will be a number of properties that are significantly impacted by construction noise. In particular, properties in Crow Lane, Jutsums Lane Bridge and Ainsley Avenue are expected to experience significant weekend construction noise impacts. A small number of properties are also expected to experience significant day construction noise impacts

2.257 Justums Lane Recreation Ground will also experience a weekend noise impact.

Offsite Road Traffic 2.258 Construction vehicles will only use the highway during the daytime (07:00 to 19:00). At façades overlooking roads used by construction traffic, the existing hourly LA10 during the daytime is predicted to increase by < 1 dB. There are therefore no significant impacts arising from construction traffic.

Vibration from Surface Activity 2.259 The plant likely to be required to construct the Romford Maintenance Depot has been reviewed to identify sources, which may produce levels of vibration sufficient to cause adverse comment from the occupants of buildings, or cause damage to buildings.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 56 17 February 2005

Depot Construction and Track-works 2.260 The construction information provided by Crossrail indicates that a wacker plate is required during the set-up of the construction worksite; that a wacker plate, tamper, oscillatory bored piling rig, and breakers are required during track-works; and that a wacker plate, tamper, oscillatory bored piling rig, breakers, vibratory piling rig, vibrating roller, and CFA piling rig are required during construction of depot structures.

Mainline Dive-Under 2.261 The construction information provided by Crossrail indicates that a wacker plate, vibratory piling rig, vibrating roller, and CFA piling rig are required for the construction of the mainline dive under.

Jutsums Lane Bridge Works 2.262 The construction information provided by Crossrail indicates that a wacker plate, breakers, and CFA piling rig are required for the construction of the mainline dive under.

2.263 Buildings or structures to be demolished have been identified, for which it is considered that vehicle mounted breakers may be required. Apart from these demolitions, the plant required to undertake the set-up of the construction sites will not be sources of significant vibration. It is assumed that the retaining walls will use a vibratory piling rig. The closest potentially sensitive location to each retaining wall is identified. Vibration levels due to CFA or oscillatory bored piling are unlikely to be significant.

2.264 Vibration levels are predicted to be in the region of 0.5 to 1.5 mm/s at 106 Saville Road during the demolition of the adjacent Gymnasium; 1 to 4 mm/s at the Viking Business Centre during the demolition of the existing buildings on the sidings; and 0.5 to 2.5 mm/s at the Royal Mail Sorting Office during the demolition of buildings and structures on the Gas Works site. Vibration levels are predicted to be less than 0.5 mm/s at 55 to 107 (odd) Vignoles Road during vibropiling of the retaining wall at, and construction of, the mainline dive under; in the region of 1 to 3 mm/s at a works building off Jutsums Lane during vibropiling of the retaining wall near to Jutsums Lane Bridge; and in the region of 1 to 3 mm/s at the Royal Mail Sorting Office during vibropiling of the retaining wall near to the new depot building. Vibration levels are predicted to be less than 1 mm/s, and less than 0.5 mm/s, at the Royal Mail Sorting Office and 51 Sheringham Avenue, during use of a tamper and vibrating roller during construction of the new depot building.

2.265 Vibration levels are not expected to exceed the threshold of significance for building damage at any receptor during any of the proposed works.

2.266 The construction activities required at this site are likely to give rise to vibration levels that are below those that correspond to a semantic rating of ‘a low probability of adverse comment’. Due to the temporary nature of such works, and with appropriate mitigation, the impact to occupants of the buildings is not likely to be significant.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 57 17 February 2005

2.267 No listed buildings, or receptors that are potentially more sensitive to vibration than residential uses, such as precision laboratories and operating theatres, have been identified that are significantly close to this worksite.

Mitigation and Residual Impacts during Construction

Noise from Surface Activity

Construction Sites and Worksites including Onsite Traffic 2.268 Hoardings of a minimum height of 2.4 m would be provided along the northern and southern boundaries of the working area and 2.4 m around the site compound. Compressors and generators operated during the night-time period would be located in noise reducing enclosures. This corresponds to Tier 2 mitigation.

2.269 In this route window, 63 properties are expected to be eligible for noise insulation due to construction noise. Of these, no properties are eligible for temporary re-housing. With these mitigation measures, there would be an estimated 23 dwellings that would experience significant residual noise impacts.

2.270 Jutsum’s Lane Recreation Ground will also experience a residual noise impacts at weekends.

Offsite Road Traffic 2.271 There are no significant residual impacts.

Vibration from Surface Activity 2.272 There are no impacts in this route window.

Impact Assessment – Permanent Impacts

Impacts during Operation

Noise from the Surface Railway 2.273 This Route Window includes the access via an underpass to the new Depot, which is via a grade-separated link from the Electric Lines. Crossrail lines are on the northern side of the rail corridor. The main Depot building is in Route Window NE9. Sensitive receptors are mostly located on the southern side of the railway at the western end of the Route Window and on the northern side of the railway at the eastern end of the Route Window. A Level 2 (assessment based upon changes in railway traffic on existing lines and on other infrastructure alterations) assessment has been carried out.

2.274 The intensification of train flows along the line will result in a maximum noise change of less than 3 dB during both the day and at night. This is below the significance criterion, hence no significant impacts are predicted in this Route Window, based on the assumptions made.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 58 17 February 2005

2.275 A detailed study of the potential maximum noise levels arising from the operation of trains has not been undertaken, as it is considered unlikely that the LAmax,F levels associated with the proposed infrastructure and traffic pattern changes will be any higher than those already experienced at nearby receptors.

Vibration from the Surface Railway 2.276 There are no significant residual impacts.

Noise from Road Traffic 2.277 When the Crossrail scheme is operational, it will cause only small increases in the 18-hour traffic flow on roads in this route window. The change in LA10,18hr corresponding to this increase in traffic is predicted to be < 1 dB. There are therefore no significant impacts arising from increases in operational traffic as a result of the scheme.

Noise from Operation of Romford Depot 2.278 The main operational area of the depot is within route window NE9. Details of the assessment of noise from the depot are therefore detailed route window NE9.

Mitigation and Residual Impacts during Operation

Noise from the Surface Railway 2.279 It can be seen from the assessment that no significant noise impacts have been identified and, as such, no mitigation is considered necessary.

2.280 A preliminary assessment has been undertaken to identify the number of residential properties which may be eligible for noise insulation under the Noise Insulation (Railways and Other Guided Transport Systems) Regulations 1996, as a result of operational railway noise from modified or altered works in the vicinity.

2.281 The results of this preliminary eligibility assessment indicate that no properties are expected to be eligible for noise insulation under the Regulations.

Vibration from the Surface Railway 2.282 There are no significant residual impacts.

Noise from Road Traffic 2.283 There are no significant residual impacts.

Noise from Operation of Romford Depot 2.284 There are no significant residual impacts.

Impacts for Sites Granted Planning Permission 2.285 St Edwards C of E School is to construct a new science and technology block within the school site. The existing school buildings are not impacted as a result of the proposed construction works, therefore the new building will also be unaffected by Crossrail works.

ROUTE WINDOW NE9 – ROMFORD STATION & DEPOT (EAST)

Overview of Route Window NE9 2.286 The main works in this route window will consist of a new depot and stabling sidings located on the old goods yard site to the west of Romford station and on the south side of the GEML. In addition, the works will include a rebuild and extension to Romford station.

2.287 Romford station is located in LB Havering, to the west of South Street on the railway viaduct between Havanna Close and Atlanta Boulevard. South Street runs through the commercial and retail centre of Romford, connecting with the Romford ring road. The site of the depot and stabling sidings is surrounded primarily by industrial and commercial uses to the south, and by the GEML and residential neighbourhoods to the north, with Oldchurch Hospital immediately to the east of Nursery Walk.

2.288 Baseline noise levels within the vicinity of this station and depot are relatively high due to both railway and road traffic noise.

Baseline 2.289 The baseline noise survey locations and durations are listed in the following table and identified on Drawing No. 1E0415-E1E000-E01-F-00009:

Long-term Medium term Short-Term Location Address (1 week) (24-hours) (3-hours) HA11 47 Beechfield Gardens x HA12 49 Sheringham Avenue x HA13 Oldchurch Hospital (western) x HA14 12 Albion Close x HA15 Oldchurch Hospital (eastern) x HA 16 Oldchurch Hospital (central) x HA17 3 Nursery Walk x

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 63 17 February 2005

2.290 Three long-term baseline surveys were undertaken at various locations within the Oldchurch hospital site, to the west (HA13), east (HA15) and centre (HA16).

2.291 HA13 was located on the western side of the Oldchurch Hospital site, to the rear of the Chapel of Rest, facing onto railway land. Observations indicated that railway movements were clearly audible; plant attached to the building operated infrequently and activities within the chapel may have marginally influenced the measured levels. The daytime baseline LAeq,12hr level was 61 dB, falling to a night-time baseline LAeq,8hr level of 55 dB, with Lmax,F levels of up to 91 dB during the night-time period (23:00 to 07:00 hours).

2.292 HA15 was located on the eastern side of Oldchurch Hospital, with the microphone positioned on the roof of a boiler house, with a clear line of sight of the railway line and a partially obstructed view of Waterloo Road. Railway movements and road traffic on Waterloo Road were the principle influences on the measured noise levels; it should be noted that no noise was audible from the operation of the boiler. The daytime LAeq,12hr baseline level was 55 dB, falling to a night-time LAeq,8hr level of 53 dB, indicating that this is a relatively quiet location.

2.293 HA16 was located centrally within the site, on the side façade of the nurses’ home at second floor height, with a restricted line of sight from the monitoring position to the railway. Hospital plant located on the main building influenced the readings whilst in operation, in conjunction with railway movements. The daytime baseline LAeq,12hr level was 68 dB, falling to a night-time baseline LAeq,8hr level of 63 dB, with Lmax,F levels of up to 87 dB.

2.294 The daytime baseline LAeq,12hr level at locations HA11, HA12 and HA14 were 62 dB, 64 dB and 68 dB, respectively, with night-time baseline LAeq,8hr levels of 57 dB, 59 dB and 63 dB. Night-time LAmax,F levels were very similar at all three locations, ranging up to 86 dB.

2.295 A 3-hour measurement was undertaken at Nursery Walk (HA17), where the measured LAeq,3hr level was 55 dB, with LAmax,F levels measured up to 75 dB. The noise environment was influenced by road traffic on Oldchurch Road, railway movements and occasional aircraft overhead. Railway noise was not considered the principle source during the daytime period.

Impact Assessment – Temporary Impacts

Impacts during Construction 2.296 Temporary impacts from construction activities are illustrated on Drawing No. 1E0315-E1E00-E01-F-00011.

Noise from Surface Activity 2.297 Appendix A provides tables for each route window giving the predicted durations of significant impacts for representative receptors. Each listed receptor is representative of one or more dwellings or other noise-sensitive location. Also included in the tables is an estimate of the numbers of dwellings that may be eligible for temporary re- housing and/or noise insulation. Appendix A should be read in conjunction with both the text below and the Construction Noise Assessment Plans provided in Volume 8 of this Technical Report.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 64 17 February 2005

Construction Sites and Works including Onsite Traffic

Romford Station Worksites 2.298 The construction programme activities that are likely to cause significant impacts include site establishment, platform and station works, creating foundations for the new station building, ticket hall and concourse works, and station fit out works.

2.299 In the vicinity of Romford Station, there will be a significant number of properties that are affected by construction noise. In particular, properties in South Street, Victoria Road, Waterloo Road, Regarth Avenue, Chandlers Way, Old Mill Parade and Gibson Court are expected to experience significant night-time and weekend noise impacts. Some properties on South Street and Victoria may experience daytime noise impacts.

Romford Depot Worksites 2.300 The construction programme is scheduled to run for just over two years and is split into 14 phases. Activities that are likely to cause significant impacts include building and track works for the depot approach, structural works to the station, mainline dive under enabling works, structural works to Jutsums Lane Bridge, sidings and track works; and enabling, construction and track works for the maintenance depot.

2.301 Around the eastern part of the proposed Romford Depot, there will be a number of properties that are significantly impacted by construction noise. In particular, properties in Beechfield Gardens and Crow Lane are expected to experience significant daytime and weekend construction noise impacts.

2.302 As part of the proposed re-development of Oldchurch Hospital, a Mental Health Unit is to be built on the western part of the existing hospital site. This would experience daytime and weekend noise impacts from depot construction. Blocks A to D of proposed keyworker housing, on the northern part of the hospital site, would also be subject to significant daytime impacts.

Offsite Road Traffic 2.303 Construction vehicles will only use the highway during the daytime (07:00 to 19:00). At façades overlooking roads used by construction traffic, the existing hourly LA10 during the daytime is predicted to increase by < 1 dB. There are therefore no significant impacts arising from construction traffic.

Vibration from Surface Activity 2.304 The plant likely to be required to construct the Crossrail elements at Romford Station has been reviewed to identify sources, which may produce levels of vibration sufficient to cause adverse comment from the occupants of buildings, or cause damage to buildings.

2.305 The construction information provided by Crossrail indicates that concrete breakers and a wacker plate are required during the set-up of the construction worksite, which includes demolition and clearance of 110 – 116 South Street; and that concrete breakers and a CFA piling rig are required during platform works.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 65 17 February 2005

2.306 With the exception of 110 – 116 South Street, no significantly substantial buildings or structures have been identified on the construction site that would require significant demolition activities, and therefore it is considered that the plant required to undertake the set-up of the construction site will not be sources of significant vibration. Vibration levels due to CFA piling are unlikely to be significant. Vibration levels from the platform works are unlikely to be significant at the nearest potentially sensitive receptors, assuming that the breakers are not vehicle mounted.

2.307 It is assumed that the demolition of 110 – 116 South Street will require vehicle mounted concrete breakers. Vibration levels are predicted to be in the region of 1 to 4 mm/s at 123 to 131 South Street, opposite the site, during demolition works. Mapping indicates that 108 South Street, a dance school and night-club, is attached or contiguous to 110 South Street. Vibration levels of concern could occur due to the structural continuity between buildings.

2.308 The threshold of significance for building damage may be exceeded at 108 South Street, although the threshold of significance is unlikely to be exceeded at any other of the surrounding buildings.

2.309 With the exception of the demolition of 110 to 116 South Street, the construction activities required at this site are likely to give rise to vibration levels that are below those that correspond to a semantic rating of ‘a low probability of adverse comment’. Levels may occur at 108 South Street that correspond to ‘adverse comment possible’ for a limited period during demolition of 110 to 116 South Street. Due to the temporary nature of such works, and with appropriate mitigation, the impact to occupants of the buildings is not likely to be significant.

2.310 No listed buildings, or receptors that are potentially more sensitive to vibration than residential uses, such as precision laboratories and operating theatres, have been identified that are significantly close to this worksite.

Mitigation and Residual Impacts during Construction

Noise from Surface Activity

Construction Sites and Worksites including Onsite Traffic

Romford Station Worksites 2.311 Hoardings of a minimum height of 2.4 m would generally be provided along the southern boundaries of the working area and around the site compound. A 3.6m hoarding would be provided along the 110-116 South Street worksite frontage. Compressors and generators operated during the night-time period would be located in noise reducing enclosures. This corresponds to Tier 2 mitigation.

2.312 In this route window, an estimated 93 properties are expected to be eligible for noise insulation due to construction noise. Included in this number are residents of approximately 3 dwellings, which may be eligible for temporary re-housing for a period. With the implementation of these mitigation measures, there would be no dwellings that would experience significant residual noise impacts.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 66 17 February 2005

Romford Depot Worksites 2.313 Hoardings of a minimum height of 2.4 m would be provided along the northern and southern boundaries of the working area and 2.4 m around the site compound. Compressors and generators operated during the night-time period would be located in noise reducing enclosures. This corresponds to Tier 2 mitigation.

2.314 An estimated 34 properties are expected to be eligible for noise insulation due to construction noise. Of these, no properties are eligible for temporary re-housing. With the implementation of these mitigation measures, there would be an estimated 12 dwellings in Beechfield Gardens, 4 dwellings in Waterloo Rd and (a nominal 4 representing 4 blocks of) the proposed keyworker housing that would experience significant residual noise impacts. The Mental Health Unit, to be built as part of the re-development of Oldchurch Hospital, would also experience daytime and weekend residual noise impacts from construction works.

Offsite Road Traffic 2.315 There are no significant residual impacts.

Vibration from Surface Activity 2.316 Vibration mitigation will be required during demolition of 110 to 116 South Street to mitigate potential impacts on 108 South Street. 108 and 110 South Street should be unattached, as far as possible using non-vibratory techniques, such as diamond sawing, before demolition commences, and should continue as it progresses. Additionally, detailed assessment should be undertaken prior to commencement of works to inform the selection of specific items of plant and working methods. An appropriate continuous vibration-monitoring regime should be adopted during demolition works allow monitoring of levels and cessation of activity should levels exceed relevant limits.

Impact Assessment – Permanent Impacts

Impacts during Operation

Noise from the Surface Railway 2.317 This Route Window includes the access to the new Depot, which is via a grade- separated link from the Electric Lines, and the Depot and Station. Crossrail lines are on the northern side of the rail corridor. The main Depot building is to be located at the old goods-yard site to the west of Romford Station. This assessment considers operational trains; the operation of the Depot has been assessed separately. Sensitive receptors are located on either side of the railway corridor and the proposed Oldchurch Hospital residential development has been included. A Level 2 (assessment based upon changes in railway traffic on existing lines and on other infrastructure alterations) assessment has been carried out.

2.318 The intensification of train flows along the line will result in a maximum noise change of less than 3 dB during both the day and at night. This is below the significance criterion, hence no significant impacts are predicted in this Route Window, based on the assumptions made.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 67 17 February 2005

2.319 A detailed study of the potential maximum noise levels arising from the operation of trains has not been undertaken, as it is considered unlikely that the LAmax,F levels associated with the proposed infrastructure and traffic pattern changes will be any higher than those already experienced at nearby receptors.

Vibration from the Surface Railway 2.320 There are no impacts in this route window.

Noise from Road Traffic 2.321 When the Crossrail scheme is operational, it will cause only small increases in the 18-hour traffic flow on roads in this route window. The change in LA10,18hr corresponding to this increase in traffic is predicted to be < 1 dB. There are therefore no significant impacts arising from increases in operational traffic as a result of the scheme.

Noise from Operation of Romford Depot 2.322 Noise from fixed plant, together with general train stabling, servicing and maintenance activities has been assessed following the BS 4142 method described in Volume 1. The assessment was based on assumptions of two ‘worst-case’ 5- minute periods during the night-time ((i) and (ii)), and one ‘worst-case’ 1-hour period during the daytime (iii):

i. A 5-minute period in the middle of the night, within which maintenance is being undertaken in the depot building, and the wheel lathe is in operation. It is assumed that there are ten trains occupying the stabling sidings that are completely powered down, and that the train wash is not in use.

ii. A 5-minute period in the early morning, within which two trains are powering up and leaving the depot, maintenance is being undertaken in the depot building, and the wheel lathe is in operation. It is assumed that there are eight trains occupying the stabling sidings that are completely powered down, and that the train wash is not in use.

iii. A 1-hour period in the daytime, within which five trains are returning to the stabling yard via the train wash, one train is arriving at the depot via the train wash, maintenance is being undertaken in the depot building, and the wheel lathe is in operation.

2.323 The results of the BS 4142 assessment are summarised below.

Night-time 2.324 No significant impacts are predicted at any residential property around the depot for either the middle of the night scenario, or the early morning scenario.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 68 17 February 2005

Middle of the Night 2.325 The highest noise levels are predicted to occur at the rear (south) façade of houses around 67 to 73 Sheringham Avenue, to the north of the depot, opposite the wheel lathe. At this location, the Rating Level, at first floor level, is approximately 6 dB below the existing LA90 (23:00 to 07:00) background noise level, assessed in accordance with BS 4142:1997. This represents a level 11 dB below the assessment criterion level of +5 dB, indicating no significant impact is predicted to occur.

Early Morning 2.326 The highest noise levels are predicted to occur at the rear (south) façade of houses around 18 to 24 Albion Close, to the north of the stabling sidings. At this location, the Rating Level, at first floor level, is approximately 5 dB above the existing LA90 (23:00 to 07:00) background noise level, for either definition of background noise level, assessed in accordance with BS 4142:1997. This represents a level equalling the assessment criterion level of +5 dB, indicating no significant impact is predicted to occur.

Daytime 2.327 No significant impacts are predicted for the assessment of the daytime period of 07:00 and 23:00 hours.

2.328 The highest noise levels are predicted to occur at the rear (south) façade of 135 to 145 Sheringham Avenue. At these locations, the Rating Level, at ground floor level, is approximately 5 dB above the existing background noise level based on the mode of the 15-minute LA90 (07:00 to 23:00), assessed in accordance with BS 4142:1997. This represents a level equalling the assessment criterion level of +5 dB, indicating no significant impact is predicted to occur.

Vibration and Groundborne Noise from the Underground Railway 2.329 Not applicable to this route window.

Mitigation and Residual Impacts during Operation

Noise from the Surface Railway 2.330 It can be seen from the assessment that no significant noise impacts have been identified and, as such, no mitigation is considered necessary.

2.331 A preliminary assessment has been undertaken to identify the number of residential properties which may be eligible for noise insulation under the Noise Insulation (Railways and Other Guided Transport Systems) Regulations 1996, as a result of operational railway noise from modified or altered works in the vicinity.

2.332 The results of this preliminary eligibility assessment indicate that no properties are expected to be eligible for noise insulation under the Regulations.

Vibration from the Surface Railway 2.333 There are no significant residual impacts.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 69 17 February 2005

Noise from Road Traffic 2.334 There are no significant residual impacts.

Noise from Operation of Romford Depot 2.335 No further noise mitigation is required over that built into the design of the depot attenuation is required and no significant residual impacts are predicted to occur.

Impacts on Sites Granted Planning Permission 2.336 No extant planning permissions that might be affected by the scheme have been identified in this route window.

ROUTE WINDOW NE10 – GIDEA PARK STATION

Overview of Route Window NE10 2.337 The main works in this route window, which is located in LB Havering, comprise platform extensions. The eastern end of two GEML island platforms (platform 3 and platform 4) will be extended eastwards by 22 m to 205 m to accommodate 10-car Crossrail trains. New platform furniture and lighting will be provided and minor station refurbishment works will be carried out. Construction at Gidea Park station will take place over approximately three months.

2.338 Works at this station will be carried out from within the existing fenced boundary of the railway on platforms three and four. It is proposed that the worksite will occupy the whole of the station car park. Access to the site for lorries will occur from the A118 Main Road via Balgores Lane and Crossways through the existing car park entrance. Large items of plant and materials will be brought to the site at Gidea Park station by rail. Other materials, including excavated materials will be delivered by road.

2.339 The main construction plant to be used at the worksite will include cranes, rail cranes, excavators, piling rigs and mechanical breakers.

2.340 Approximately two lorries in total per day will access the Gidea Park station worksites during a peak construction period of about a month. At other times, the worksite will typically be served by one lorry per day.

2.341 The area around the station is surrounded by residential and small-scale retail areas. The site lies within the Gidea Park Conservation Area.

Baseline 2.342 One baseline noise survey location was selected in this route window, of which details are included on Drawing No. 1E0415-E1E000-E01-F-00010.

2.343 A 24-hour measurement was carried out close to Gidea Park Station at 5 Eyre Close (HA01). The measured baseline LAeq,12hr noise level was 64 dB during the daytime and 58 dB LAeq,8hr at night, with night-time LAmax,F levels of up to 86 dB. Railway movements were clearly audible at this location and dominated the noise environment, due to the close proximity of the tracks.

Impact Assessment – Temporary Impacts

Impacts during Construction 2.344 Temporary impacts from construction activities are illustrated on Drawing No. 1E0315-E1E00-E01-F-00010

Noise from Surface Activity 2.345 Appendix A provides tables for each route window giving the predicted durations of significant impacts for representative receptors. Each listed receptor is representative of one or more dwellings or other noise-sensitive location. Also included in the tables is an estimate of the numbers of dwellings that may be eligible for temporary re- housing and/or noise insulation. Appendix A should be read in conjunction with both the text below and the Construction Noise Assessment Plans provided in Volume 8 of this Technical Report.

Construction Sites and Worksites including Onsite Traffic 2.346 Only one significant noise impact is expected to occur due to construction works programmed at Gidea Park Station. A daytime impact is expected to occur at 5 Eyre Close, to the north of the tracks.

Offsite Road Traffic 2.347 Construction vehicles will only use the highway during the daytime (07:00 to 19:00). At façades overlooking roads used by construction traffic, the existing hourly LA10 during the daytime is predicted to increase by < 1 dB. There are therefore no significant impacts arising from construction traffic.

Vibration from Surface Activity 2.348 The plant likely to be required to construct the Crossrail elements at Gidea Park Station has been reviewed to identify sources, which may produce levels of vibration sufficient to cause adverse comment from the occupants of buildings, or cause damage to buildings.

2.349 The construction information provided by Crossrail indicates that concrete breakers and a wacker plate are required during the set-up of the construction worksite; that concrete breakers and a CFA piling rig are required during platform works.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 75 17 February 2005

2.350 No significantly substantial buildings or structures have been identified on the construction site that would require significant demolition activities, and therefore it is considered that the plant required to undertake the set-up of the construction site will not be sources of significant vibration. Vibration levels due to CFA piling are unlikely to be significant. Vibration levels from the platform or station works are unlikely to be significant at the nearest potentially sensitive receptors, assuming that the breakers are not vehicle mounted.

2.351 Vibration levels are not expected to exceed the threshold of significance for building damage at any receptor during any of the proposed works.

2.352 The construction activities required at this site are likely to give rise to vibration levels that are below those that correspond to a semantic rating of ‘a low probability of adverse comment’. Due to the temporary nature of such works, and with appropriate mitigation, the impact to occupants of the buildings is not likely to be significant.

2.353 No listed buildings, or receptors that are potentially more sensitive to vibration than residential uses, such as precision laboratories and operating theatres, have been identified that are significantly close to this worksite.

Mitigation and Residual Impacts during Construction

Noise from Surface Activity

Construction Sites and Works including Onsite Traffic 2.354 Standard 2.4 m high hoardings would be provided around the site compounds and worksites, with a small section of 3.6 m high hoarding to be erected on the southern side of the tracks. Compressors and generators operated during the night-time period would be located in noise reducing enclosures. This corresponds to Tier 2 mitigation.

2.355 In this route window, no properties may be eligible for noise insulation due to construction noise and no dwellings are expected to be eligible for temporary re- housing. With the implementation of these mitigation measures, only one residential property within the vicinity of Gidea Park Station would be subject to a significant residual construction noise impact.

Offsite Road Traffic 2.356 There are no significant residual impacts.

Vibration from Surface Activity 2.357 There are no significant residual impacts.

Impact Assessment – Permanent Impacts

Impacts during Operation

Noise from the Surface Railway 2.358 Intensification of train flows along the line will result in a maximum noise change that is less than 3 dB during both the day and at night. This is below the significance criterion, hence no impact would occur.

Vibration from the Surface Railway 2.359 There are no impacts in this route window.

Noise from Road Traffic 2.360 When the Crossrail scheme is operational, it will cause only small increases in the 18-hour traffic flow on roads in this route window. The change in LA10,18hr corresponding to this increase in traffic is predicted to be < 1 dB. There are therefore no significant impacts arising from increases in operational traffic as a result of the scheme.

ROUTE WINDOW NE11 – GIDEA PARK STABLING SIDINGS

Overview of Route Window NE11 2.365 The proposed Crossrail works at Gidea Park involve the extension of existing sidings and provision of new sidings in order to provide stabling for Crossrail trains. The Gidea Park stabling site is located in LB Havering, on the site of the existing sidings to the east of Upper Brentwood Road and some 150 m to the east of Gidea Park station. An area of mature woodland exists to the north of the sidings.

2.366 The current stabling sidings are surrounded primarily with residential neighbourhoods to the north and south of the station, with light industrial units and warehousing to the south of the rail corridor. An established belt of vegetation separates housing areas to the north from the railway sidings. The Royal Liberty School is located on the northern side of Upper Brentwood Road. There are few shops in the locality, with no obvious town centre location. Light industrial, residential and commercial areas are located on the Southend Arterial Road to the east of the stabling sidings.

2.367 Baseline noise levels within this route window are relatively low and are mainly associated with noise from the railway sidings.

Baseline 2.368 The baseline noise survey location and duration is listed in the following table and identified on Drawing No. 1E0415-E1E000-E01-F-00011.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 79 17 February 2005

Long-term Medium term Short-Term Location Address (1 week) (24-hours) (3-hours) HA02 12 Cambridge Avenue x

2.369 Noise measurements over a 7 day period were carried out at 12 Cambridge Avenue (HA02), near the existing Gidea Park rail stabling facility. Additional sidings are proposed at Gidea Park for overnight stabling of Crossrail trains, to provide stabling for ten trains of 240m in length, together with a turn back siding. The measured baseline noise level was found to be 62 dB LAeq,12hr during the daytime and 55 dB LAeq,8hr at night, with night-time LAmax,F levels of up to 92 dB. During the weekend period, the day-time LAeq,12hr baseline level was 57 dB, with the night-time LAeq,8hr level of 51 dB. Train noise was the dominant noise source, with background traffic also audible.

Impact Assessment – Temporary Impacts

Impacts during Construction 2.370 Temporary impacts from construction activities are illustrated on Drawing No. 1E0315-E1E00-E01-F-00011.

Noise from Surface Construction Activity 2.371 Appendix A provides tables for each route window giving the predicted durations of significant impacts for representative receptors. Each listed receptor is representative of one or more dwellings or other noise-sensitive location. Also included in the tables is an estimate of the numbers of dwellings that may be eligible for temporary re- housing and/or noise insulation. Appendix A should be read in conjunction with both the text below and the Construction Noise Assessment Plans provided in Volume 8 of this Technical Report.

Construction Sites and Works including Onsite Traffic 2.372 The construction programme is scheduled to run for 29 months and is split into 12 phases. Activities that are likely to cause significant impacts include site mobilisation, construction of retaining walls, excavation, bridge construction over Ravensbourne Channel, installation of sidings and trackworks.

2.373 In the vicinity of the Gidea Park Sidings worksite, there will be a number of properties that are significantly impacted by construction noise. In particular, properties in Upper Brentwood Road, Cambridge Avenue, Amery Gardens, Coopers Court, Tallis Court, Ashlyn Grove, Ardleigh Close and Stafford Avenue are expected to experience significant daytime construction noise impacts.

2.374 No properties are expected to experience significant night-time construction noise impacts as the durations of night-time working are not expected to be sufficient to meet the temporal criteria of 10 days in 15 days, or 40 days in 6 months at any location

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 80 17 February 2005

2.375 Some properties in Amery Gardens, Stafford Avenue, Evelyn Sharp House and Interwood House are expected to experience significant weekend construction noise impacts.

Offsite Road Traffic 2.376 There will be no off-site construction traffic in this route window.

Vibration from Surface Activity 2.377 The plant likely to be required to construct the Gidea Park Stabling Sidings has been reviewed to identify sources, which may produce levels of vibration sufficient to cause adverse comment from the occupants of buildings, or cause damage to buildings.

2.378 The construction information provided by Crossrail indicates that concrete breakers, a wacker plate, and a vibratory piling rig are required during the set-up of the construction worksite; that concrete breakers are required during works at the bridge over the Ravensbourne Channel; and a CFA piling rig is required to construct the retaining walls at the north of the site.

2.379 No significantly substantial buildings or structures have been identified on the construction site that would require significant demolition activities, and therefore it is considered that the plant required to undertake the set-up of the construction site will not be sources of significant vibration, with the exception of the vibratory piling rig. However, there are no indications to what for, and where, the vibratory piling rig will be used. Vibration levels due to CFA piling are unlikely to be significant. Vibration levels from the works at the bridge over the Ravensbourne Channel are unlikely to be significant at the nearest potentially sensitive receptors due to the separation distance.

2.380 Vibration levels may exceed the threshold of significance for building damage at locations close to works during vibratory piling. Vibration levels are not expected to exceed the threshold of significance for building damage at any receptor during the remainder of the proposed works.

2.381 With the exception of vibratory piling, the construction activities required at this site are likely to give rise to vibration levels that are below those that correspond to a semantic rating of ‘a low probability of adverse comment’. Due to the temporary nature of such works, and with appropriate mitigation, the impact to occupants of the buildings is not likely to be significant.

2.382 No listed buildings, or receptors that are potentially more sensitive to vibration than residential uses, such as precision laboratories and operating theatres, have been identified that are significantly close to this worksite.

Mitigation and Residual Impacts during Construction

Noise from Surface Activities

Construction Sites and Works including Onsite Traffic 2.383 Hoardings of a minimum height of 3.6 m would be provided along the northern and southern boundaries of the working area and 2.4 m around the site compound. Compressors and generators operated during the night-time period would be located in noise reducing enclosures. This corresponds to Tier 2 mitigation.

2.384 In this route window, 29 residential properties are expected to be eligible for noise insulation due to construction noise. No dwellings are expected to be eligible for temporary re-housing. With these mitigation measures, an estimated 146 dwellings would experience significant residual noise impacts.

Offsite Road Traffic 2.385 Not applicable to this route window.

Impact Assessment – Permanent Impacts

Impacts during Operation

Noise from the Surface Railway 2.386 In this Route Window there are proposed changes to the railway (permanent way) infrastructure in the vicinity of the existing Gidea Park stabling sidings. The existing five Road facility will be upgraded to nine Roads to accommodate the introduction of Crossrail railway movements. There will also be a change in the composition of railway traffic along the Great Eastern corridor with the implementation of Crossrail. The predicted noise changes attributable to the infrastructure and forecast railway traffic changes in the vicinity of the sidings have been calculated taking account of the new alignments, precise mix of expected rail vehicles and the operating speeds of the various train types. A Level 3 (detailed assessment) assessment has been carried out for this area.

2.387 The resulting changes in noise levels for receptors close to the railway tracks would be as follows:

Time Number of Significant Impacts Period Noise Noise Increase Decrease Slight Moderate Substantial >3 dB 3-5 dB 6-10 dB >10 dB Day (07:00 to 0 0 0 0 23:00 hrs) Night (23:00 to 0 0 0 0 07:00 hrs)

Note: Noise changes calculated in terms of the LAeq,16hr for Day and LAeq,8hr for Night

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 82 17 February 2005

2.388 The above table indicates that the changes to the infrastructure and services will not result in an increase in noise levels. On this basis there will be no significant impacts. The noise generated by the trains travelling along the Great Eastern Main and Electric Lines dominates the noise climate in this area. The introduction of the modified and upgraded sidings does not introduce any significant impacts at nearby receptors primarily due to the lower speeds and numbers of trains using the sidings compared to those on the Great Eastern Lines.

2.389 A detailed study of the potential maximum noise levels arising from the operation of trains has not been undertaken, as it is considered unlikely that the LAmax,F levels associated with the proposed infrastructure and traffic pattern changes will be any higher than those already experienced at nearby receptors.

Vibration from the Surface Railway 2.390 There are no impacts in this route window.

Noise from Road Traffic 2.391 Not applicable to this route window.

Mitigation and Residual Impacts during Operation

Noise from the Surface Railway 2.392 It can be seen that from this assessment that no significant noise impacts have been identified, and as such no further mitigation has been considered.

2.393 A preliminary assessment has been undertaken to identify the number of residential properties which may be eligible for noise insulation under the Noise Insulation (Railways and Other Guided Systems) Regulations 1995, as a result of operational railway noise from modified or altered works in the vicinity.

2.394 The results of this preliminary eligibility assessment indicate that no properties are expected to be eligible for noise insulation under the Regulations.

Vibration from the Surface Railway 2.395 There are no significant residual impacts.

Noise from Road Traffic 2.396 To be completed when data are available.

Impacts on Sites Granted Planning Permission 2.397 On the site of 438 Brentwood Road, planning permission has been submitted to construct a 60 unit residential block. This development is adjacent to the Gidea Park Sidings worksite and hence may be subject to a significant residual noise impact due to Crossrail construction works.

ROUTE WINDOW NE12 – HAROLD WOOD STATION

Overview of Route Window NE12 2.398 The main works in this route window, which is located in LB Havering, comprise platform extensions. Two GEML platforms (platform three and platform four) will be extended eastwards by 38 m to 205 m to accommodate 10-car Crossrail trains. In addition, new platform furniture and lighting will be fitted and minor station refurbishment works will be carried out. The works will take approximately four months to complete.

2.399 Construction works will be carried out from within the existing fenced boundary of the railway on platforms two/three and four. The worksite servicing activities on the site will be located in part of the existing station car park to the northeast of platform four. Access to the main station entrance and forecourt will occur from Gubbins Lane. Large items of plant and materials for construction will be delivered and removed by rail. Other materials, including excavated materials will be removed by road.

2.400 The main construction plant to be used at the worksite will include cranes, rail- mounted cranes, excavators and mechanical breakers.

2.401 Approximately three lorries in total per day will access the worksite during a peak construction period that will last for a month and a half. At other times, the worksite will typically be served by one lorry per day.

2.402 The area around the station comprises residential neighbourhoods to the northeast, south and east, with small retail and commercial units along the northern sides of Station Road and Oak Road. Harold Wood Hospital is located to the northwest of the station, accessed from Gubbins Lane. Areas of open space exist at Harold Wood Park and along Ingrebourne River and Paines Brook.

2.404 A 24-hour measurement was carried out at 15 Fitzilian Avenue (HA03), near Harold Wood Station. The measured baseline noise level was found to be 66 dB LAeq,12hr during the daytime and 58 dB LAeq,8hr at night, with night-time LAmax,F levels of up to 87 dB. Due to the proximity of the train tracks (running to the rear of the garden, on a 3m high embankment), train noise is the dominant noise source, with movements noted to be frequent throughout the day.

2.408 In the vicinity of Harold Wood Station, the areas of existing housing to the south of the railway line would experience significant construction noise impacts from the proposed construction activities to extend the station platforms.

Offsite Road Traffic 2.409 Construction vehicles will only use the highway during the daytime (07:00 to 19:00). At façades overlooking roads used by construction traffic, the existing hourly LA10 during the daytime is predicted to increase by < 1 dB. There are therefore no significant impacts arising from construction traffic.

ROUTE WINDOW NE15 – BRENTWOOD STATION

Overview of Route Window NE15 2.465 The main works in this route window, which is located in Brentwood BC, comprise platform extensions. Two GEML platforms (platforms three and four) will be extended eastwards by 21 m to 205 m to accommodate 10-car Crossrail trains.

2.466 The platform works will comprise widening to the north side of platform four and of island platform two/three to accommodate 10-car Crossrail trains. In addition, new platform furniture and lighting will be fitted and minor station refurbishment works will be carried out. The works will take approximately four months to complete.

2.467 Construction works will be carried out from within the existing fenced boundary of the railway on platforms two/three and four. The worksite servicing activities on the site will be located in part of the existing station car park to the northeast of platform four. Access to the site will be made via The Parade through the existing car park entrance. Materials for the platform construction works will be delivered and removed by rail. Other materials, including excavated materials will be removed by road.

2.468 The main construction plant to be used at the worksite will include cranes, excavators and mechanical breakers.

2.469 Approximately two lorries in total per day will access the worksites during a peak construction period that will last a month. At other times, the worksite will be served by one lorry per day.

2.470 The area around Brentwood station comprises small-scale commercial, retail and light industrial premises, while the wider area is primarily residential. Baseline

2.472 A 24-hour measurement was carried out close to Brentwood Station at Glamis House (BW01). The baseline daytime level at this location was 74 dB LAeq,12hr, with night- time LAeq,8hr level of 67 dB, and night-time LAmax,F levels of up to 97 dB. Railway noise was the dominant noise source at this location.

Impact Assessment – Temporary Impacts

Impacts during Construction 2.473 Temporary impacts from construction activities are illustrated on Drawing No. 1E0315-E1E00-E01-F-00015.

Noise from Surface Activity 2.474 Appendix A provides tables for each route window giving the predicted durations of significant impacts for representative receptors. Each listed receptor is representative of one or more dwellings or other noise-sensitive location. Also included in the tables is an estimate of the numbers of dwellings that may be eligible for temporary re- housing and/or noise insulation. Appendix A should be read in conjunction with both the text below and the Construction Noise Assessment Plans provided in Volume 8 of this Technical Report.

Construction Sites and Works including Onsite Traffic Grout Shafts 2.475 In the vicinity of Brentwood Station, no noise-sensitive receptors are expected to be significantly affected by construction noise.

Offsite Road Traffic 2.476 Construction vehicles will only use the highway during the daytime (07:00 to 19:00). At façades overlooking roads used by construction traffic, the existing hourly LA10 during the daytime is predicted to increase by < 1 dB. There are therefore no significant impacts arising from construction traffic.

Vibration from Surface Activity 2.477 The plant likely to be required to construct the Crossrail elements at Brentwood Station has been reviewed to identify sources, which may produce levels of vibration sufficient to cause adverse comment from the occupants of buildings, or cause damage to buildings.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 100 17 February 2005

2.478 The construction information provided by Crossrail indicates that concrete breakers and a wacker plate are required during the set-up of the construction worksite; and that concrete breakers and a CFA piling rig are required during platform works.

2.479 No significantly substantial buildings or structures have been identified on the construction site that would require significant demolition activities, and therefore it is considered that the plant required to undertake the set-up of the construction site will not be sources of significant vibration. Vibration levels due to CFA piling are unlikely to be significant. Vibration levels from the platform works are unlikely to be significant at the nearest potentially sensitive receptors, assuming that the breakers are not vehicle mounted.

2.480 Vibration levels are not expected to exceed the threshold of significance for building damage at any receptor during any of the proposed works.

2.481 The construction activities required at this site are likely to give rise to vibration levels that are below those that correspond to a semantic rating of ‘a low probability of adverse comment’. Due to the temporary nature of such works, and with appropriate mitigation, the impact to occupants of the buildings is not likely to be significant.

2.482 No listed buildings, or receptors that are potentially more sensitive to vibration than residential uses, such as precision laboratories and operating theatres, have been identified that are significantly close to this worksite.

Hoardings 2.4 m high would also be provided along the southern railway boundary approximately opposite that on the north side. Compressors and generators during night-time periods would be located in noise reducing enclosures. This corresponds to Tier 2 mitigation.

2.484 No properties are expected to be eligible for noise insulation or temporary re-housing due to construction noise. There will be no properties that would be subject to a significant residual construction noise impact.

ROUTE WINDOW NE17 – SHENFIELD STATION

Overview of Route Window NE17 2.514 Works in this route window, which is located in Brentwood Borough Council (BC), include the provision of additional stabling, a new platform and alterations to the Southend and Colchester rail lines. Works will occur principally in railway land along an existing rail corridor. The current land use in the immediate surrounding area is mainly residential with some small retail outlets and offices situated to the north of the station, along Hutton Road.

2.515 Baseline noise levels within this route window are moderate and mainly associated with noise from the railway.

Baseline 2.516 The baseline noise survey locations and durations are listed in the following table and identified on Drawing No. 1E0415-E1E000-E01-F-00017:

Long-term Medium term Short-Term Location Address (1 week) (24-hours) (3-hours) BW02 10 Hunter Avenue x BW03 81 Hunter Avenue x

2.517 Two 24-hour measurements were undertaken close to Shenfield Station, at 10 Hunter Avenue (BW02) and 81 Hunter Avenue (BW03), both of which were free-field positions in the gardens of the properties.

2.518 The daytime baseline LAeq,12hr levels were 62 dB and 61 dB respectively, with night- time baseline LAeq,8hr levels of 55 dB and 56 dB. Night-time maximum LAmax,F levels of up to 85 dB and 83 dB were recorded at each location. Train movements are the dominant noise source on measured noise levels at both locations.

Impact Assessment – Temporary Impacts

Impacts during Construction 2.519 Temporary impacts from construction activities are illustrated on Drawing No. 1E0315-E1E00-E01-00017.

Noise from Surface Activity 2.520 Appendix A provides tables for each route window giving the predicted durations of significant impacts for representative receptors. Each listed receptor is representative of one or more dwellings or other noise-sensitive location. Also included in the tables is an estimate of the numbers of dwellings that may be eligible for temporary re- housing and/or noise insulation. Appendix A should be read in conjunction with both the text below and the Construction Noise Assessment Plans provided in Volume 8 of this Technical Report.

Construction Sites and Works including Onsite Traffic 2.521 A number of properties are predicted to experience a significant noise impact from the construction activities associated with Shenfield Station with its associated Western Sidings, and Shenfield Turnback Sidings, to the east of the Station. Noise- sensitive residential properties subject to significant construction noise impacts are concentrated within the vicinity of Hutton Avenue, Alexander Lane, Friar’s Avenue, Herrington Grove, Hunter Lane and Rayleigh Road. The greatest impacts are expected to occur in the day-time period. However, night-time and weekend construction works may also significantly impact a substantial number of properties. Although evening work is also scheduled, works are only expected to affect a small number of properties in Herrington Avenue.

2.522 Significant daytime impacts may also be expected at the following non-residential sensitive receptors: Herrington Prep School, off Mount Avenue, a Library on Hutton Road and a Medical Surgery, off Herrington Road. The School and Library may experience day, night and weekend impacts, with the Surgery also impacted during the evening period. Nevertheless, due to the nature of the School and Surgery buildings, it is unlikely that they will be in use during the night-time and weekend periods and will therefore only constitute a significant impact during the daytime and evening periods as indicated. However, it is likely that the Library will be open to the public during the weekend period and will therefore be significantly impacted during both the day and weekend periods.

Offsite Road Traffic 2.523 Construction vehicles will only use the highway during the daytime (07:00 to 19:00). At façades overlooking roads used by construction traffic, the existing hourly LA10 during the daytime is predicted to increase by < 1 dB. There are therefore no significant impacts arising from construction traffic.

Vibration from Surface Activity

Shenfield Station Worksite 2.524 The plant likely to be required to construct the Crossrail elements at Shenfield Station has been reviewed to identify sources, which may produce levels of vibration sufficient to cause adverse comment from the occupants of buildings, or cause damage to buildings.

2.525 The construction information provided by Crossrail indicates that concrete breakers and a wacker plate are required during the set-up of the construction worksite; that concrete breakers and a CFA piling rig are required during platform works; that breakers, a vibrating roller, a tamper, and CFA piling rig are required during track- works; and that breakers, a vibrating roller, and CFA piling rig are required for construction of retaining walls.

2.526 No significantly substantial buildings or structures have been identified on the construction site that would require significant demolition activities, and therefore it is considered that the plant required to undertake the set-up of the construction site will not be sources of significant vibration. Vibration levels due to CFA piling are unlikely to be significant. Vibration levels from the platform works are unlikely to be significant at the nearest potentially sensitive receptors, assuming that the breakers are not vehicle mounted.

2.527 Vibration levels are not expected to exceed the threshold of significance for building damage at any receptor during any of the proposed works.

2.528 The construction activities required at this site are likely to give rise to vibration levels that are below those that correspond to a semantic rating of ‘a low probability of adverse comment’. Due to the temporary nature of such works, and with appropriate mitigation, the impact to occupants of the buildings is not likely to be significant.

2.529 No listed buildings, or receptors that are potentially more sensitive to vibration than residential uses, such as precision laboratories and operating theatres, have been identified that are significantly close to this worksite.

Shenfield Sidings Worksite 2.530 The plant likely to be required to construct the Crossrail elements of the Shenfield Stabling Sidings has been reviewed to identify sources, which may produce levels of vibration sufficient to cause adverse comment from the occupants of buildings, or cause damage to buildings.

2.531 The construction information provided by Crossrail indicates that a vibrating roller and a wacker plate are required during the set-up of the construction worksite; that breakers, a wacker plate, and a tamper, are required during track-works; and that breakers, a vibrating roller, and CFA piling rig are required for construction of retaining walls.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 111 17 February 2005

2.532 No significantly substantial buildings or structures have been identified on the construction site that would require significant demolition activities, and therefore it is considered that the plant required to undertake the set-up of the construction site will not be sources of significant vibration, with the possible exception of the vibrating roller. Vibration levels due to CFA piling are unlikely to be significant.

2.533 Vibration levels are predicted to be less than 2 mm/s at residential properties on the south side of Hunter Avenue, during track-works and construction of the retaining walls.

2.534 Vibration levels are not expected to exceed the threshold of significance for building damage at any receptor during any of the proposed works.

2.535 The construction activities required at this site are likely to give rise to vibration levels that are below those that correspond to a semantic rating of ‘a low probability of adverse comment’. Due to the temporary nature of such works, and with appropriate mitigation, the impact to occupants of the buildings is not likely to be significant.

2.536 No listed buildings, or receptors that are potentially more sensitive to vibration than residential uses, such as precision laboratories and operating theatres, have been identified that are significantly close to this worksite.

Mitigation and Residual Impacts during Construction

Noise from Surface Activity

Construction Sites and Works including Onsite Traffic 2.537 Hoardings of a minimum height of 3.6 m would be provided around the main work site areas and site compounds. Compressors and generators operated during the night-time period would be located in noise reducing enclosures. In addition, hoardings of a minimum height of 2.4 m would be provided along the railway embankment, to provide noise screening from track works. This corresponds to Tier 2 mitigation.

2.538 In summary, within this route window, 144 properties are expected to be eligible for noise insulation due to construction noise, of which 35 properties would be eligible for temporary re-housing. With the implementation of these mitigation measures, there will be in total 108 residual impacts, with approximately 106 residual daytime impacts and 31 residual weekend impacts.

Offsite Road Traffic 2.539 There are no significant residual impacts.

Impact Assessment – Permanent Impacts

Impacts during Operation

Noise from the Surface Railway 2.540 In this Route Window there are proposed changes to the railway (permanent way) infrastructure in the vicinity of the existing Shenfield station. As well as retaining the existing 3 no carriage sidings to the north west of the station, the two sidings located to the east of the station will be removed and replaced with three slightly longer sidings. The extra space required for the new sidings footprint also requires some modifications to the alignments of the existing through lines. A Level 3 (detailed assessment) assessment has been carried out for this area.

2.541 There will also be a change in the composition of railway traffic along the Great Eastern corridor with the implementation of Crossrail. The predicted noise changes attributable to the infrastructure and forecast railway traffic changes in the vicinity of the sidings have been calculated taking account of the new alignments, precise mix of expected rail vehicles and the operating speeds of the various train types.

2.542 The resulting changes in noise levels for receptors close to the railway tracks would be as follows:

Time Number of Significant Impacts Period Noise Decrease Noise Increase Slight Moderate Substantial >3 dB 3-5 dB 6-10 dB >10 dB Day (07:00 to 0 0 0 0 23:00 hrs) Night (23:00 to 0 0 0 0 07:00 hrs)

Note: Noise changes calculated in terms of the LAeq,16hr for Day and LAeq,8hr for Night

2.543 The above table indicates that the changes to the infrastructure and services will not result in an increase in noise levels. On this basis there will be no significant impacts. The noise generated by the trains travelling along the Great Eastern Main and Electric Lines dominates the noise climate in this area. The introduction of the new sidings and the changes to the existing through line configurations does not introduce any significant impacts at nearby receptors primarily due to the lower speeds and numbers of trains using the turnback sidings compared to overall number of trains on the Great Eastern Lines.

2.544 A detailed study of the potential maximum noise levels arising from the operation of trains has not been undertaken, as it is considered unlikely that the LAmax,F levels associated with the proposed infrastructure and traffic pattern changes will be any higher than those already experienced at nearby receptors.

Vibration from the Surface Railway 2.545 There are no impacts in this route window.

JAE2748 N&V TechRep Vol6 - North East Final_WM.doc 113 17 February 2005

Noise from Road Traffic 2.546 When the Crossrail scheme is operational, it will cause only small increases in the 18-hour traffic flow on roads in this route window. The change in LA10,18hr corresponding to this increase in traffic is predicted to be < 1 dB. There are therefore no significant impacts arising from increases in operational traffic as a result of the scheme.

Mitigation and Residual Impacts during Operation

Noise from the Surface Railway 2.547 It can be seen that from this assessment that no significant noise impacts have been identified, and as such no further mitigation has been considered.

2.548 A preliminary assessment has been undertaken to identify the number of residential properties which may be eligible for noise insulation under the Noise Insulation (Railways and Other Guided Transport Systems) Regulations 1996, as a result of operational railway noise from modified or altered works in the vicinity.

2.549 The results of this preliminary eligibility assessment indicate that no properties are expected to be eligible for noise insulation under the Regulations.

Vibration from the Surface Railway 2.550 There are no significant residual impacts.

Noise from Road Traffic 2.551 There are no significant residual impacts.

Impacts on Sites Granted Planning Permission 2.552 On the site of 22 Rayleigh Road, Shenfield, planning permission has been submitted for the demolition of an existing office and workshop, erection of a 3/4 storey building containing 14, two bedroom apartments. This site is close to Shenfield Station and is predicted to be subject to a significant noise impact from Crossrail construction works.

ROUTE WINDOW R1 – PITSEA SIDINGS

Overview of Route Window R1 2.553 The main works within this route window will involve the development of a rail siding for unloading excavated material from rail to road for final delivery to the landfill site at Pitsea. The permanent works will comprise the introduction of railway tracks, trains, lighting columns, unloading equipment, a new access road and a new building at the entrance to the site for use during the transfer of excavated materials to the disposal site. On completion of their use for Crossrail, all temporary buildings, sidings and equipment will be removed.

2.554 The site is bounded to the north by a belt of open land. The elevated A13 highway passes between 15 and 130 m to the north of the site on the far side of this open land. A hypermarket and residential buildings on the southern edge of Basildon are located to the immediate north of this highway. The eastern boundary of the site is bounded by Pitsea Hall Lane. The area to the south is occupied by open marshland along with the Pitsea Landfill operated by Cleanaway.

Baseline 2.555 The baseline noise survey locations and durations are listed in the following table and identified on Drawing No. 1E0415-E1E000-E01-F-00018.

Long-term Medium term Short-Term Location Address (1 week) (24-hours) (3-hours) BA01 Chestnut Road x BA02 Brackendale Avenue x BA03 Pitsea Hall Lane x

2.556 Excavated material will be transported to this site by rail. At this site it will be off- loaded, then transported by HGVs along Pitsea Hall Lane.

2.557 The current assumption is that no additional sidings will be required at this site (this is to be confirmed as it is still under review); therefore no impacts will be associated with these. Some work to the railhead may be required.

2.558 A number of short-term measurements have been undertaken at the three sites indicated. Measurements consisted of three 15-minute measurements undertaken at each of the sites during day and night-time periods. The measurement procedure is representative of the 3-hour measurement period.

2.559 At 102 – 116 Chestnut Road (BA01) the dominant noise source was road traffic on the A13, with a high percentage of HGVs. At this point the A13 is elevated and runs between the monitoring location and proposed worksite. The daytime baseline LAeq,3hr was 70 dB, with a LAmax of 108 dB. The night-time baseline LAeq,3hr was 54 dB, with the LAmax ranging between 72 and 79 dB.

2.560 The daytime baseline LAeq,3hr level at 107 Brackendale Road (BA02) was 61 dB, with LAmax,F levels ranging between 79 and 83 dB. The night-time LAeq,3hr level was 50 dB, with the night-time LAmax,F level of up to 78 dB. The dominant noise source at this location was that due to road traffic, albeit distant and faint. Train movements were only just audible.

2.561 Location BA03 was positioned on the footpath outside the residential dwelling opposite the horse sanctuary. The daytime baseline LAeq,3hr level was 66 dB, falling to a night-time LAeq,3hr of 50 dB. Measured LAmax,F levels ranged up to 91 dB during the daytime period and 81 dB during the night-time period. Road traffic on Pitsea Hall Lane was noted to be busy during the daytime period, due to the Country Park, Household Goods Waste Site and Landfill Site located at the end of the lane. However, at night the dominant noise source was faint road traffic noise from the A13.

Impact Assessment – Temporary Impacts

Impacts during Construction 2.562 Temporary impacts from construction activities are illustrated on Drawing No. 1E0315-E1E00-E01-00018.

Noise from Surface Activity 2.563 Appendix A provides tables for each route window giving the predicted durations of significant impacts for representative receptors. Each listed receptor is representative of one or more dwellings or other noise-sensitive location. Also included in the tables is an estimate of the numbers of dwellings that may be eligible for temporary re- housing and/or noise insulation. Appendix A should be read in conjunction with both the text below and the Construction Noise Assessment Plans provided in Volume 8 of this Technical Report.

Construction Sites and Works including Onsite Traffic

Railway Sidings 2.564 An area to the northwest of the railway sidings may be significantly affected by night- time construction noise. Several property blocks which may be impacted include; The Glen (15 to 81), Chestnut Road (102 to 164) and Waterville Drive (118 to 128). The A13 runs between the railway sidings site and impacted properties to the northwest. In addition, properties to the northeast of the site, which are elevated and overlook the site may also be significantly impacted during the night-time period, these include three properties in the Fieldway area.

2.565 The sensitivity of Pitsea Hall, a function venue, situated to the south of the existing tracks, has been difficult to determine, but this and it’s associated play area may experience significant daytime, evening and night-time impacts, due to works being undertaken at the railway sidings.

2.566 No other non-sensitive impacts have been identified.

2.567 Within this route window, a total of 53 residential impacts have been identified, resulting from construction and operation of the sidings, and from offsite road traffic.

Offsite Road Traffic 2.568 Excavated material from the railway sidings site will be loaded onto HGVs and transported to the landfill site via Pitsea Hall Lane. Due to landfill licensing constraints excavated material will only be transported during the daytime period.

2.569 It is understood that this will be undertaken under the existing Landfill Licence. Construction vehicles will only use the highway during the daytime (07:00 to 19:00). At façades overlooking roads used by construction traffic, the existing hourly LA10 during the daytime is predicted to increase by < 1 dB. There are therefore no significant impacts arising from construction traffic.

Vibration from Surface Activity

2.570 There are no impacts in this route window.

Mitigation and Residual Impacts during Construction

Noise from Surface Activity

Construction Sites and Works including Onsite Traffic 2.571 Hoardings of a minimum height of 2.4 m would be provided along the northern, eastern and western boundaries of the working areas and site compounds, whilst still allowing site access. This corresponds to Tier 1 mitigation.

2.572 In this route window, an estimated 50 properties may be eligible for noise insulation due to railway siding activities. No residential properties will be eligible for temporary re-housing. With the implementation of these mitigation measures, 3 properties may be subject to significant residual construction noise impacts. Properties eligible for noise insulation are concentrated in the area to the northwest of the site, off The Glen, Chestnut Road and Waterville Drive.

Offsite Road Traffic 2.573 There are no significant residual impacts.

Vibration from Surface Activity 2.574 There are no significant residual impacts.
