EXECUTIVE SUMMARY

The site occupies a roughly ‘T’ shaped plot of land extending to some 0.31ha located on the western side of Seddlescombe Street, Seddlescombe. It is proposed to redevelop the site for new residential properties.

The site appears to have largely comprised open field with terraced properties on the eastern boundary from before the publication of the earliest maps. The southern wing of the Roselands building is shown to have been constructed some time between 1961 and 1977, with the northern wing added by 1981.

The site is mapped as being underlain by the Ashdown Formation, comprising siltstone and mudstone. Deposits of Head are indicated to be present close to the western boundary of the site.

The underlying Ashdown Formation deposits are classified as a Secondary A aquifer while the Head deposits are classified as a Secondary Undifferentiated aquifer.

The site is not situated within a Groundwater Source Protection Zone (SPZ) with respect to potable groundwater.

The site is not located within a flood zone.

The site is not within a radon affected area.

While no specific sources of contamination have been identified by the qualitative assessment, made ground associated with the development of the site may be contaminated.

Made ground was generally recorded across the site to depths of between 0.25m and 1.0m, extending to a depth of 1.5m within borehole WS105. Underlying the surfacing and/ or made ground, each of the exploratory holes passed down into undisturbed interbedded silt and sand with subordinate horizons of clay, gravel, mudstone and sandstone, to the full depth of investigation.

Groundwater was recorded to lie at depths of between 1.38m and 3.29m below ground level.

An overall classification of NHBC MEDIUM Volume Change Potential (VCP) is recommended for the clay soils.

The soils are classified by the BRE as sulphate design class DS-1, and, assuming a mobile groundwater table, the ACEC class is AC-1.

Light pumping from sumps should be sufficient to control perched or surface water ingress into excavations. Where water is encountered in association with the granular soils, running sand conditions should be anticipated.

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe

The site is not considered suitable for conventional soakaways, and allowance should be made for surface water to be positively drained off site.

An allowable bearing capacity of 120kPa is recommended for shallow foundations, minimum width 600mm, bearing within the undisturbed medium dense and dense silt and sand of the Ashdown Formation.

Suspended floor slabs are recommended.

A design CBR value of 2% is recommended where undisturbed soils are present at proposed formation depths, reducing to 1% where made ground soils are present. The subgrade soils should be assumed to be frost susceptible.

Appropriate Health and Safety precautions must be adhered to where man entry into excavations is required.

The works to date have not identified any significant contamination with respect to identified human health receptors.

No significantly elevated levels of contamination have been recorded within any of the samples tested.

No specific remedial work is considered to be required to protect future site users/ controlled water against contamination. However, further testing will be require following site clearance, specifically beneath existing buildings, to confirm the findings of the current works. It is considered that the soils would likely be classified as non hazardous for waste disposal purposes.

A INTRODUCTION

1 Authority

Leap Environmental Ltd (hereafter referred to as LEAP) has been appointed by Chartway Group to undertake a Phase 1 Desk Study and Phase II intrusive Site Investigation of the site referred to as Roselands, Seddlescombe, Kent. The instruction was given in an email dated 10th May 2016 from Peter Smith of Chartway Group.

2 Objective

LEAP understands that it is proposed to redevelop the site with new low rise residential dwellings as per the attached layout in Figure 2.

The proposed development is currently at a final design phase and has been assessed in accordance with BS EN 19971, as being a Geotechnical Category 1 structure.

The objectives of this report are to:

 Provide information on the geotechnical and environmental quality of the ground present on the site;

 Assess the potential health and other environmental risks posed by the site to the proposed development and to other specifically identified receptors; and

 Assess the potential for offsite contamination to adversely affect the proposed development.

3 Scope of Works

This report describes a two stage process whereby the site is investigated and risks are assessed. The terms geotechnical and geoenvironmental are referred to throughout the report.

Geoenvironmental refers principally to the chemical nature of the ground and the degree of soil, water and/or land gas contamination and the impact that contamination may have on current or future development and also on the wider environment.

1 BS EN 1997-1(2004) Eurocode 7:Geotechnical Design - Part 1:General Rules

Page | 9

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe

Geotechnical refers to all other aspects of the ground conditions and the impact they may have on the physical construction of existing or future development, principally foundations, slope stability, drainage, pavement and road design and groundwater control.

The investigation comprises two phases of work.

3.1 Phase 1 Scope The first part of this report presents the results of a desk study and site reconnaissance. It provides a review of previous site investigation and remediation validation reports, where they have been made available by the Client or where LEAP has been able to locate that information from third party sources. The previous reports referred to are detailed above. The following sources of information have also been reviewed:

 Envirocheck database report

 Envirocheck Historical map Search

 British Geological Survey (BGS) mapping

 British Geological Survey website (www.bgs.ac.uk) including historic BGS borehole data

 Unexploded WWII aerial delivered bomb (UXB) regional risk maps produced by Zetica

 Interrogation of the Environment Agency Web site on 17th May 2016.

 Interrogation of the World Wide Web on 17th May 2016 for general information pertaining to the site history

A site reconnaissance was carried out on 17th May 2016.

The desk study and site reconnaissance have been used to develop an initial conceptual site model, which forms the basis for the site investigation strategy. The initial site conceptual model is used to identify geotechnical and geoenvironmental hazards and the qualitative degree of risk associated with them. In terms of the geoenvironmental assessment the conceptual site model is used to identify potential sources of contamination, potential receptors and pathways by which the two may be connected. These are known as possible pollutant linkages and it is these pollutant linkages that are key to contaminated land risk assessment.

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe

The Phase I investigation is also referred to as a Preliminary Investigation2 .

3.2 Intrusive Investigation Scope The Phase II work comprises intrusive investigation, onsite monitoring and laboratory analysis. The results of these works are used to validate and/or update the initial site conceptual model. This phase of site investigation comprised the following tasks:

 7 No. windowless boreholes drilled with a tracked rig to depths of between 2.7m and 3.5m

 3 No. 2.6m to 3.0m deep machine excavated trial pits;

 3 No. BRE365 soakage tests

 In-situ geotechnical testing including Standard Penetrometer Tests and hand penetrometer tests within the boreholes;

 Geotechnical Laboratory Testing including Atterberg Limit Tests, and Sulphate Tests; and

 Chemical Laboratory tests including 8 No. LEAP standard soil suite tests.

The intrusive works were completed by contractors who have been scrutinised and are on LEAP’s approved contractor list. The windowless sampling and BRE365 testing was carried out by Oakland Site Investigation Limited, and the machine excavated trial pits were carried out by Spillane Plant Hire Ltd. The fieldwork was supervised by LEAP.

Selected samples of soil were scheduled for laboratory testing for a wide range of potential contaminants including metals, polyaromatic hydrocarbons and asbestos. The laboratory testing has been carried out by The Environmental Laboratory Ltd at its laboratories in East Sussex.

Selected soil samples have been classified by laboratory analysis for geotechnical design purposes. The laboratory testing has been carried out by K4 Soils Laboratories Ltd at its laboratories in Watford.

The final stage in the geoenvironmental assessment comprises a quantitative risk assessment and revision of the preliminary Conceptual Site Model. Preliminary recommendations for remediation have been provided, based on various development assumptions which are detailed in the following section and in the text of this report. The risk assessment has been

B PHASE I – DESK STUDY

5 Environmental Setting

5.1 Site Location and Description The site occupies a roughly ‘T’ shaped plot of land extending to some 0.31ha located on the western side of Seddlescombe Street, Seddlescombe. The approximate National Grid Reference of the site is TQ7802 1810 and the site lies at an estimated elevation of some 30m Above Ordnance Datum (mAOD).

5.1.1 General Description and Boundaries The current site layout is shown in Figure 3, Appendix B. A walkover survey was carried out on 17th May 2016 and photographs are included within Appendix E.

The site is bounded by Seddlescombe Street to the east and by residential properties on the remaining site boundaries.

At the time of the walkover the site was occupied by a one and two storey ’T’ shaped brick built former care home with associated soft landscaping surrounds. The southern wing of the building is aligned approximately east to west, while the northern wing is aligned north to south. Various mature trees and bushes were present around the site boundaries.

The ground surface across the site generally fell in a westerly direction with various moderately steep banks being present across the site.

5.2 Geology The geology of the site has been ascertained by reference to the 1:50,000 British Geological Survey sheet 320/ 321, solid and drift edition, the BGS website (www.bgs.ac.uk) and the Envirocheck report.

The site is mapped as being underlain by the Ashdown Formation, comprising siltstone and mudstone. Deposits of Head are indicated to be present close to the western boundary of the site.

5.2.1 Head Head deposits accumulated largely by solifluction (the slow downslope movement of soil in response to the seasonal freezing and thawing of ground) and hillwash, mainly under periglacial conditions during the Quaternary glaciations. In general it occurs beneath concave slopes on the flanks and floors of valleys. It is locally derived and its content reflects the base geology, in this instance it comprises of variable deposits of impure clays, silts and sands, locally gravelly.

Page | 13

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe

5.2.2 Ashdown Formation The Ashdown Formation largely comprises interbedded siltstone and sandstone with subordinate horizons of mudstone/ shale. The siltstone/ sandstone deposits generally weather to silt and sand, with the shale/ mudstone weathering to clay. Locally the beds may be rich in iron. 5.2.3 BGS Boreholes The online BGS Geoindex (http://www.bgs.ac.uk/geoindex/) has been reviewed for detailed local geological and hydrogeological information. A single borehole is located in the vicinity of the site, however no strata is recorded.

5.3 Hydrogeology The hydrogeology of the site has been ascertained from the Envirocheck data report. The source of the data is reported to be the Environment Agency groundwater vulnerability mapping.

The underlying Ashdown Formation deposits are classified as a Secondary A aquifer. The superficial Head deposits mapped close to the site are classified as a Secondary Undifferentiated aquifer.

The site is not situated within a Groundwater Source Protection Zone (SPZ) with respect to potable groundwater.

The Envirocheck lists six abstraction licences within 1000m of the subject site, the closest being a distance of some 604m to the south west and relates to abstraction of surface water.

Whilst it cannot be conclusively determined with the works carried out to date, it is likely given the topography of the site, groundwater flow would be in a generally westerly direction.

5.4 Hydrology The closest surface water feature listed is a tertiary river located some 49m to the west of the site.

The closest surface water feature for which the Environment Agency have surface water quality data is some 326m to the south of the site.

The Envirocheck report indicates that there are three discharge consents within 250m of the site. The nearest relates to discharge if domestic treated effluent some 108m to the north west of the site, discharging to a freshwater stream.

Three pollution incidents relating to controlled waters are listed within 500m of the site. The nearest is located some 305m to the south east of the site and relates to a collapsed sewer.

5.5 Flooding

Page | 14

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe

According to the Environment Agency, the site is not located within a flood zone.

The western most part of the site is located within a zone of potential flooding of property situated below ground level (e.g. basement structures)

5.6 Designated Environmentally Sensitive Sites A review of designated environmentally sensitive sites presented within the Envirocheck report has been carried out. The dataset makes reference to a number of sensitive sites including the following:

 Sites of Special Scientific Interest (SSSI);  Records of National Nature Reserves (NNR);  Areas of Special Conservation (SAC);  Records of Special Protection Areas (SPA);  Records of Ramsar Sites;  Records of Local Nature Reserves;  Ancient Woodland Records.

The site is located within an Area of Outstanding Natural Beauty and within a Nitrate Vulnerable Zone. This is an area where water draining from the land can impact nitrate levels in surface water or groundwater.

The proposed development is not considered to pose a significant risk to either of these environmentally sensitive areas.

5.7 Ground Workings No current or historical ground workings are reported by the Envirocheck / Groundsure report within 500m of the site.

5.8 Mining, Extraction and Natural Cavities The Envirocheck report indicates the site is not situated within an area affected by coal mining. The site is reported to be in an area of rare non coal mining. No natural cavities are recorded within 1000m of the site.

6 Site Usage

Page | 15

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe

6.1 Current Land Use The current site layout is shown in Figure 3, Appendix B.

The site is currently occupied by a former care home with associated soft landscaped surrounds.

No contemporary trade entries are listed within the site boundaries.

6.2 Evidence of Onsite Contamination No specific potentially contaminative activities were recorded to be present on site. However, terracing of the ground surface to form banks across the site indicates the presence of made ground that could potentially be contaminated.

6.3 Neighbouring Land Use A total of 10 contemporary trade entries are listed within 500m of the site. The closest relates to an inactive photocopiers located some 197m to the east. The remaining activities comprise vehicle repair and other garaging services. The majority of these activities are listed as inactive.

6.4 Evidence of Off Site Contamination No evidence of potentially contaminative activities in the vicinity of the site have been recorded.

6.5 Site History The contaminative and development history of the site has been ascertained with reference to the Ordnance Survey historical maps.

In summary the site appears to have largely comprised open field with terraced properties on the eastern boundary from before the publication of the earliest maps. The southern wing of the Roselands building is shown to have been constructed some time between 1961 and 1977, with the northern wing added by 1981. The site is located in a generally rural area with sporadic residential development associated with the expansion of Seddlescombe.

6.5.1 Historical Map Evidence The historical Ordnance Survey maps provided spanned the period from 1874 to present day at scales of 1:10,000, 1:2,500 and 1:1,250. The maps are included in full in Appendix C.

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe the site as determined from the desk study and historical review. Secondly the risk of UXO has been assessed by reference to the unexploded WWII aerial delivered bomb (UXB) regional risk maps produced by Zetica.

The Zetica risk maps indicate a low risk. In addition, no military activity has been identified in the area. Hence the overall risk of UXO is rated as low.

6.7 Waste Planning and Landfill Records 6.7.1 Recorded Landfill Sites The closest landfill site is listed some 717m to the south west, comprising a historical landfill mixed waste site that operated between 1982 and 1986

No active landfills are listed within 1000m of the site.

6.7.2 Waste Management Facilities No facilities are listed within the Envirocheck report.

6.7.3 Waste Transfer or Treatment Sites No waste transfer or treatment sites are listed within the Envirocheck report.

6.8 Other Regulatory Records No other regulatory recorded are listed within 1000m of the site.

6.9 Radon According to the Envirocheck database search, the site is not within a radon affected area (less than 1% of homes are above the action level for radon). Therefore, no special protective measures are required in the construction of buildings on this site, in respect of radon gas.

C PRELIMINARY CONCEPTUAL SITE MODEL

7 Environmental Risk Assessment

7.1 Conceptual Site Model (CSM) A risk based approach is used to assess contaminated or potentially contaminated land within the UK. For a potential risk to exist, there must be a pollutant linkage in place, i.e. there must be a source of contamination, a potential receptor, and a pathway linking the two.

In order to quantify the magnitude of the risk, it is necessary to first calculate the potential exposure of the receptor as a result of all the individual active pollutant linkages affecting that receptor. Secondly it is necessary to ascertain “what is an acceptable exposure level for each of the identified receptors and contaminants?”. Various numerical models are available to aid in the assessment and these are discussed in more detail in Section G below.

The purpose of the Conceptual Site Model, in this instance, is to identify all of the potential pollutant linkages by considering, in turn, the potential sources, receptors and pathways.

7.2 Sources 7.2.1 Onsite Sources Based on a review of the available site information, the following contaminants of concern are proposed:

Table 3: Onsite sources of contamination

Source Contaminants of Concern

Made Ground associated with Heavy metals, PAH, asbestos landscaping

No specific sources of contamination have been identified at the site.

7.2.2 Offsite Sources Various potential contaminative activities have been identified in the vicinity of the site. However, due to their distance to the site and/ or nature of the activity, none of these sources are considered to pose a significant risk to the site.

Page | 19

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe

7.3 Receptors Potential receptors are those which may be impacted by any of the contaminants of concern identified above, and include the following:-

 Future residents

 Construction workers

 Groundwater – Secondary A Aquifer (Ashdown Formation)

 Material construction of buildings and infrastructure

7.4 Pathways and Potential Pollutant Linkages The development will include private gardens and public open space. All potential pollutant linkages involving resident humans and soil contaminants will be active i.e. direct ingestion of soil, ingestion of soil attached to plants as well as via plant uptake, inhalation of indoor and outdoor vapour and of dust tracked back into the house and finally ingestion of water carried by plastic water pipes through contaminated ground.

Ground workers are at risk as a result from all of the above, except for those involving edible plants.

The site is underlain by a Secondary A aquifer of Intermediate leaching potential. Hence there is a potential pathway for leachate from soil pollutants and for mobile liquid contaminants to enter the groundwater. Given the recorded potential for underground structures to flood along the western boundary of the site, it is anticipated the groundwater beneath the site will be at relatively shallow depth.

7.5 Qualitative Risk Assessment of Pollutant Linkages Risk levels within the preliminary CSM are determined on a qualitative basis following review of the available desk-based information. The significance of particular pollutant linkages is dependant both upon the severity and likelihood of the risk. These two factors are summarised in the following tables.

The potential pollutant linkages are summarised in the table appended in Appendix D and given a qualitative risk classification in accordance with current guidance. The details of the risk assessment methodology is also presented in Appendix D.

7.6 Conclusions The main risk of contamination on the site is from potential made ground associated with the site’s development.

8 Geotechnical Risk Assessment

8.1 Geotechnical Risk Register The preliminary geotechnical risk register for the proposed development is summarised in the table in Appendix D. Details of the risk assessment methodology are presented in Appendix D.

8.2 Conclusions The following geotechnical hazards have been identified as Significant or Substantial:-

D PHASE II - INTRUSIVE INVESTIGATION

9 Investigation Rationale

A total of ten trial holes were excavated across the site. These included seven windowless sampler boreholes to depths of between 2.7m and 3.5m and three machine excavated trial pits to depths of 2.6m and 3.0m.

The trial holes were located to give general coverage, taking into consideration the proposed development and the potential geoenvironmental and geotechnical risks/hazards highlighted by the CSM in accordance with BS10175 for an exploratory investigation.

The trial holes have also been located in accordance with an exploratory investigation with the recommendations for the spacing and depth of investigation given in EC7 Part 2 Annex B.

Groundwater monitoring wells have been installed in boreholes WS101 and WS103.

The trial holes were located to avoid the line of a deep mains sewer running approximately south east to north west beneath the site.

The site investigation locations are shown on Figure 3, Appendix B.

10 Site Work

10.1 Date and Weather Conditions The intrusive investigations were undertaken on the 20th and 27th May 2016. At the time of the investigations, the weather was dry and cloudy.

10.2 Site Work Methods 10.2.1 Borehole Drilling Seven boreholes were drilled using a windowless sampler rig (designated WS101 to WS107). The windowless sampling rig consists of a tracked barrow with a sampling unit mounted on the top. When in the required position, the mast is raised allowing a mechanised drop weight to fall repeatedly onto an anvil, and drive attached sample tubes or probe rods into the ground to produce reasonably intact continuous samples which were then extracted using the integrated hydraulic ram.

To reduce any tendency of the tubes to stick in the ground, a succession of smaller diameters may be used to obtain full depth. Excavated soils were placed aside for inspection and sampling.

On completion the trial hole was backfilled with excavated material, placed in reverse order, and the surface reinstated unless otherwise specified.

10.2.2 Trial Pitting Three trial pits were dug by a backhoe excavator at positions suggested by the client and designated SA1 to SA3. The trial pits were typically 0.6m wide by 2.5m long. Trial pit dimensions are shown on the trial pit logs, included as Appendix F. On completion the pits were backfilled in reverse order and left mounded to allow for future settlement.

10.2.3 Soil Logging and Sampling Soil samples were recovered from the boreholes and trial pits for field screening, logging and sampling.

Boreholes were logged in general accordance with the requirements of BS 5930: 1999+A2:2010 and BS EN ISO 14688 Pt 1&2. The trial hole logs are presented in Appendix F.

Samples were collected with a clean sampling trowel or by hand (using dedicated nitrile gloves for each sampling location). Samples were placed into laboratory supplied sampling containers, specific to the type of analyses required.

All sample containers were sealed and labelled with a unique location identity, depth and date of sampling.

10.2.4 Groundwater Monitoring Well Installation Two groundwater monitoring wells were installed within boreholes WS101 and WS103 during the investigation. The monitoring wells were constructed of 50mm diameter HDPE pipe. The response zone was typically targeted to intercept the groundwater surface and was surrounded by washed filter gravel. The slotted zone was surrounded with bentonite to provide a seal. The monitoring wells were finished with bungs and steel covers concreted flush with the ground surface. Monitoring well installations are shown on the borehole logs and summarised in the following table.

11 Ground Conditions

The ground conditions are described in detail in the logs attached in Appendix F. In summary the soil conditions were as follows:

Table 7: Summary of soils encountered

Depth Depth Soil Type Description From (m) To (m)

GL 0.10-0.50 TOPSOIL TOPSOIL. No topsoil recorded in WS101, WS103, WS104 or SA1.

GL-0.50 0.25-1.50 MADE MADE GROUND: generally comprising sand GROUND with subordinate horizons of clay, containing a variable proportion of flint, clinker, ash, brick, sandstone, glass and metal.

No made ground recording within WS102, SA2 or SA3.

0.15-1.50 >3.50 ASHDOWN Generally comprising medium dense and dense FORMATION SAND and SILT with subordinate horizons of sandy silty CLAY, GRAVEL, MUDSTONE and SANDSTONE.

Made ground was generally recorded across the site to depths of between 0.25m and 1.0m, extending to a depth of 1.5m within borehole WS105. No made ground was recorded within WS102, SA2 or SA3, all of which were located across the southern part of the site.

No visual or olfactory evidence of contamination was recorded within the made ground soils recovered.

Page | 25

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe

Underlying the surfacing and/ or made ground, each of the exploratory holes passed down into undisturbed interbedded silt and sand with subordinate horizons of clay, gravel, mudstone and sandstone, to the full depth of investigation. The gravel recorded at the base of trial pit SA3 is considered to represent weathered bedrock.

Based on the in-situ testing carried out, the silt and sand deposits can be considered to be in a medium dense and dense condition and the clay to be stiff.

The undisturbed soils are judged to be representative of the Ashdown Formation predicated on the published geology map. No Head deposits were recorded within any of the trial holes excavated.

11.1.1 Groundwater With the exception of borehole WS103, where groundwater was encountered at a depth of 3.3m below ground level, all of the trial holes remained dry during excavation.

A single return visit to monitor the standpipes was carried out on 27th May 2016. The monitoring results are included in Appendix I and are summarised as follows:-

Table 8: Groundwater Monitoring Results

Monitoring Depth to groundwater well (mbgl)

WS101 3.29

WS102 1.38

It is noted that the ground level at the position of borehole WS101 was some 2m higher than that of borehole WS103. It is therefore considered that the ground water level across the site is likely to be sub horizontal or falling slightly towards the west.

11.1.2 Other Observations All of the trial holes remained stable during the course of the intrusive investigation.

E GEOTECHNICAL INFORMATION

12 Strata Encountered

12.1 Made Ground The site is underlain by made ground to depths of between 0.25m and 1.50m, generally comprising sand with subordinate layers of clay.

Made ground or fill is by nature highly variable in both composition and bearing capacity, and can be subject to large differential settlements when loaded. It is therefore generally unsuitable for use as a bearing stratum. In addition, made ground may contain contaminated and/or putrescible material. It can therefore be potential source of contamination and landfill gas.

12.2 Ashdown Formation The made ground was underlain by silt and sand to the full depth of investigation. The results of the geotechnical laboratory testing are summarised in Error! Reference source not found. and the table below.

Table 9: Summary of Geotechnical Test Results for Ashdown Formation

Test Range

SPT ‘N value’ 9-59 Moisture Content (%) 17-18 Liquid Limit (%) 44 Plastic Limit (%) 22-25 Plasticity Index (%) 19-22 Sulphate Content (g/l) 0.07-0.28 pH 7.76-7.92

Atterberg limits carried out on the more cohesive soils of the Ashdown Formation indicate that they are of intermediate plasticity.

The sand deposits may be considered to be non plastic and hence non shrinkable.

Based on the field observations the mudstone and sandstone is classified as very weak.

F GEOTECHNICAL APPRAISAL

The foregoing geotechnical appraisal does not constitute a Geotechnical Design Report in accordance with EN1997. The following recommendations are for preliminary design purposes only.

For the detailed design, the short-term and long-term design situations must be considered. Where relevant, the following limit states should be considered:-

 Loss of equilibrium of the structure or the ground, considered as a rigid body, in which the strengths of structural material and the ground are significant in providing resistance (EQU)  Internal failure or excessive deformation of the structure or structural elements in which the strength of structural materials is significant in providing resistance (STR)  Failure or excessive deformation of the ground, in which the strength of soil or rock is significant in providing resistance (GEO)  Loss of equilibrium of the structure or the ground due to uplift by water pressure or other vertical actions (UPL)  Hydraulic heave, internal erosion and piping in the ground caused by hydraulic gradients (HYD)

The following factors should also be considered.

 Overall stability and ground movements  Nature and size of the proposed construction including the design life  Conditions with regards to the surroundings (e.g. neighbouring structures, traffic, utilities, vegetation, contamination etc.)  Ground and groundwater conditions  Influence of the environment.

13 Swelling and Shrinkage

Based on the laboratory test results in Section E, an overall classification of NHBC MEDIUM Volume Change Potential (VCP) is recommended for the clay soils.

The sand deposits can be assumed to be non plastic and hence non shrinkable.

The site is underlain by fine grained soils of medium shrinkage potential and coarse grained soils that can be expected to be non shrinkable. Given the interbedded nature of the cohesive soils, it would be prudent to assume a MEDIUM shrinkage potential when designing all foundation depths near to trees in accordance with NHBC Chapter 4.2. In addition, it is recommended that suitable void forming materials are included on the faces of foundations.

Page | 28

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe

Foundation depths should be calculated based on the mature height of the tree, however, the existing height is relevant for trees which are to be removed.

14 Sulphates

Three samples of the Ashdown Formation were tested for sulphate content and pH. In accordance with the BRE8 methodology and the number of samples tested, the site has been classified on the highest measured sulphate content.

Based on the results detailed in Section E and the above, the soils are classified by the BRE as sulphate design class DS-1, and, assuming a mobile groundwater table, the ACEC class is AC- 1.

15 Groundwater

Groundwater depths of between 1.38m and 3.29m below ground level have been recorded within the installed standpipes.

Where encountered at shallow depth, light pumping from sumps should be sufficient to control perched or surface water ingress into excavations. Where water is encountered in association with the granular soils, running sand conditions should be anticipated.

Long term groundwater monitoring was beyond the scope of works and would be required to fully assess the groundwater regime.

16 Soakage Potential

16.1 Test Results Three soakage tests were undertaken on site in general accordance with BRE3659. Given the time restrictions, it was only possible to fill and test each pit once. None of the tests carried out recorded a fall in water level below 25% of the starting water depth. Calculation of the soil infiltration rate in strict accordance with the BRE digest is therefore not possible. The infiltration rate has therefore been simply calculated by dividing the volume of water lost over the test period against the average surface area of the trial pit.

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe

The results are attached in Appendix F and are summarised below:

Table 10: Summary of soakage tests

Test Location Soakage Rate Comments (m/s) SA1 4.0x10-6

SA2 8.9x10-7

SA3 8.0x10-8

16.2 Recommendations Based on the above results, the site is not considered suitable for conventional soakaways, and allowance should be made for surface water to be positively drained off site.

17 Bearing Capacity and Foundations

17.1 Shallow Foundations All loads should be transferred beneath any topsoil, made ground, loose, soft, low strength, desiccated or disturbed soils and transferred onto the medium dense and dense silt and sand soils beneath the site.

For low rise housing, based on local experience and BS810310 Table 8, an allowable bearing capacity of 120kPa is recommended for shallow foundations, minimum width 600mm, bearing within the undisturbed medium dense and dense silt and sand of the Ashdown Formation. As noted in Section 13 above, a general MEDIUM shrinkage potential for the soils should be assumed and foundations should be deepened appropriately near trees in line with NHBC requirements or to non-shrinkable soils, whichever is less.

Where foundations are stepped or span different soil types, allowance should be made for nominal reinforcement.

18 Floor Slabs

10 BS8103-1:2011 Structural design of low rise buildings BSI

Page | 30

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe

With reference to NHBC Standard 5.2, suspended floor slabs are recommended:-

 Where the depth of fill exceeds 600mm  Where foundations are deepened below 1.5m in accordance with NHBC Standards Chapter 4.2  Where desiccated soils are encountered  Where vibratory ground improvement techniques have been used  Where foundations have been piled.

Suspended floor slabs are therefore recommended on site.

19 Roads

It is understood that access roads and a car parking area will be present across the southern part of the site. The made ground in this area can be expected to extend to depths of between 0.40m and 0.75m below ground level.

As a preliminary guide, IAN 73 0611 and LR113212 indicate an estimated CBR value for silt of 1% and sand of 20%. Given the high silt content of the near surface soils, the subgrade should be assumed to be frost susceptible.

19.1.1 Recommendations A design CBR value of 2% is recommended where undisturbed soils are present at proposed formation depths.

Given the high silt content of the near surface soils, the subgrade should be assumed to be frost susceptible.

Further confirmatory testing may be required if the proposed roads are to be adopted.

Page | 31

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe

Excavations in the made ground and granular soils are likely to be unstable and subject to collapse. Close lateral support will be required in all excavations where man entry is required.

Running sands and piping in excavation bases should also be anticipated associated with ingress of groundwater. Excavations extending below the water table will require dewatering.

Appropriate Health and Safety precautions must be adhered to where man entry into excavations is required. Even stiff clay soils at shallow depth can collapse, particularly following wet weather, and great care should be taken at all times.

21 Filling

The preliminary recommendations contained within this report assume that ground levels are to remain at a similar level across the site for the proposed development, and that no significant changes in level are proposed. In the event that ground levels are to be raised, this may induce significant settlement, particularly across the areas of deeper made ground, which could adversely affect foundation design, drainage etc. Where significant changes in ground levels are proposed then further investigation will be required to assess the impact of such earthworks on the above recommendations.

22 Settlement

Based on the allowable bearing capacity given in Section 17, settlements should be within typical tolerable limits for the low rise development proposed. At this stage it is assumed that ground levels will remain at the current level for the proposed development. If significant level raises are proposed, this may induce significant settlement in the natural soils and detailed settlement analyses will be required. Where foundations are stepped or span different soil types, differential settlement should be anticipated and allowance should be made for nominal reinforcement.

23 Heave and Uplift

In accordance with NHBC Standards Chapter 4.2, precautions against heave should be used where foundations are within the influence of trees and the resulting foundation depth is greater than 1.5m. Compressible material must be provided against the inside faces of all external wall foundations greater than 1.5m in depth. For pier and beam foundations, additional voids are required below ring beams.

Heave may also occur where shrinkable soils are unloaded, in say, basement excavations. To avoid uplift pressures, voids or buffer zones should be left beneath floor slabs. As a preliminary

Page | 32

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe guide, allowance should be made for a 200mm void. This should be confirmed at the detailed design stage.

G GEO-ENVIRONMENTAL APPRAISAL

24 Conceptual Site Model

The has identified a number of potential pollutant linkages.

On-site sources of contamination identified by the preliminary conceptual site model likely to impact the site include heavy metal, PAH and asbestos within made ground from development of the site.

These sources are considered to pose a low to moderate risk to human receptors and a moderate/ low risk to controlled waters.

25 Testing Strategy

25.1 Soil Sampling Trial hole locations were spread evenly across the site to provide even, non-targeted coverage. Samples have been tested for the presence of the identified contaminants of concern (heavy metals, PAH compounds and asbestos) as detailed above. It is noted that access across the site was limited due to the presence of existing buildings.

26 Assessment Criteria

26.1 Human Health Assessment Criteria Pollutant linkages containing human health have been risk assessed by comparing the soil laboratory test results to Tier 1 Site Assessment Criteria. These are based on published Soil Guideline Values or LQM/CIEH Generic Assessment Criteria13 (GAC) assuming a residential land use.

In accordance with current HPA guidance14, the assessment of PAHs has been carried out using a surrogate marker approach, whereby the assessment of risk from Benzo(a)Pyrene also

Page | 34

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe captures potential risks from other carcinogenic PAHs that may be present. The threshold PAHs have been assessed similarly, by using Naphthalene as a marker compound.

In this report, the recently released Category 4 screening level (C4SL)15 has been used as an assessment criterion for lead. It is noted, that this is significantly lower than previously accepted screening levels (less than half), but is based on current and evolving toxicological assessment carried out on behalf of DEFRA. The ramifications for the UK contaminated land industry are such that further development of this position is possible.

26.1.1 Statistical Assessment In assessing soil test results and comparing them to any threshold or screening value, an assessment must first be made as to how accurately the test results reflect the true mean of the contaminant level within the ground. In this assessment for each parameter the test data have been subjected to statistical assessment based on the methodology set out in CIEH report 2008: Guidance on comparing Soil Contamination Data with a Critical Concentration.

The Upper Confidence Level or U95 value is thereby calculated as being the level at which we would be 95% confident that the true mean is less than this value. For the purposes of this assessment, a conservative approach has been adopted in the statistics. All non-detect values have been treated as being equal to half the limit of detection.

It should be noted that for the purposes of these assessments, no statistical outliers have been excluded. The CIEH guidance document that accompanies the statistics calculator states:

outliers should be excluded from a dataset ONLY where they:

o are obviously and demonstrably the result of an error that can be identified and explained, or

o clearly indicate that more than one soil population exists within the dataset and this can be justified by (or informs the further development of) the conceptual model

26.2 Groundwater and Surface Water Assessment Criteria Groundwater testing was beyond the scope of this investigation. By way of a preliminary qualitative assessment, consideration has been given to the total soil concentrations and the sensitivity of any potential pollutant linkages involving controlled waters.

Notes to table

1. Assessment criterion based on inorganic Mercury

There is at least a 95% confidence limit that the true mean of each of the above parameters is below the Acceptance Criteria. That is to say that, statistically, there is an acceptable degree of confidence that the soils are not contaminated with any of the above parameters.

In addition, a single sample of topsoil and the natural soils were tested for the above determinants. Neither of these samples recorded concentration of the contaminants testing exceeding their respective GAC’s.

27.2 Polyaromatic Hydrocarbons (PAH)

Page | 36

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe

PAH are widespread within made ground and the urban environment generally. They are one of the most common contaminants in made ground and the one that most commonly drives remediation. Benzo(a)Pyrene is a particular problem, being very commonly found in association with tarmac, clinker and any burnt products and also being highly toxic to human health. The assessment criterion for BaP is close to levels that are found naturally in many topsoils and this makes it very difficult for any population of soils to pass the CIEH statistics with a 100% evidence level.

The BaP and naphthalene results have been subject to statistical analysis as for the metals.

The mean Soil Organic Matter of the population has been used to determine an appropriate Tier 1 GAC for each population. The results are summarised as follows:

Table 12: Summary of BaP and Naphthalene in made ground (5 samples)- mean SOM 1%

Benzo(a)Pyrene 0.3 5 0.5 100 0.83

Naphthalene 0.1 5 0.1 100 1.5

There is at least a 95% confidence limit that the true mean of both of the above parameters is below the Acceptance Criteria. That is to say that, statistically, there is an acceptable degree of confidence that the soils are not contaminated with either of the above parameters.

In addition, a single sample of topsoil and the natural soils have been tested for the presence of the above determinants. Neither of these samples recorded concentration of the contaminants testing exceeding their respective GAC’s.

27.3 Asbestos All of the soil samples tested were screened for the presence of asbestos containing materials and/or loose asbestos fibres. None of the samples tested recorded the presence of asbestos.

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe

28 Risk Assessment

28.1 Human Health The works to date have not identified any significant contamination with respect to identified human health receptors.

Whilst the assessment has not found any significant contamination, access into some areas, specifically beneath the existing buildings, has not been possible and there remains the possibility that as yet unidentified contamination may be present.

28.2 Controlled Waters 28.2.1 Groundwater The site is underlain by the Ashdown Formation which comprises a Secondary A aquifer. The site is not located within a Source Protection Zone with respect to potable water.

Specific laboratory testing has not been carried out as part of this investigation to enable a detailed quantitative risk assessment in respect of groundwater. The measured levels of potential contaminants within the made ground soils are generally low, with only one sample (WS101 at 0.3m) recording a slightly elevated level of lead.

The concentrations recorded are unlikely to pose a significant risk to groundwater. This assessment should be reconsidered if significant contamination is identified at a later stage.

28.2.1 Surface Water There are no surface water features on or adjacent to the site. The closest surface water feature is a tertiary river located some 49m to the west of the site. Based on this information and the recorded low concentrations of contaminants the site is not considered to pose a risk to surface water receptors.

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe

H REMEDIATION

29 Remediation of on-site Contamination

29.1 Soil Contamination No significantly elevated levels of contamination have been recorded within any of the samples tested. As such, no specific remedial work is considered to be required to protect future site users/ controlled water against contamination. However, further testing will be require following site clearance, specifically beneath existing buildings, to confirm the findings of the current works.

29.2 Discovery Strategy Close attention should be paid and inspections undertaken of all stripped formations. It is considered that there remains the potential for additional as yet unidentified contamination to be encountered. The potential for contamination is considered greatest beneath the former area of development.

Should any suspect material be identified a revised risk assessment may be required.

30 Provision of Clean cover in garden areas

The existing topsoil and undisturbed soils at the site is considered suitable for reuse elsewhere on site, subject to confirmatory testing. In general terms, any imported soils, if required, should be approved by a suitably qualified geoenvironmental engineer prior to importation or placement. The proposed sources should be assessed on the basis of either a detailed site investigation or laboratory test results in the case of a manufactured topsoil. In the absence of this data then further testing may be required prior to importation or placement. All imported soils, sub soil and top soil should be subject to the test parameters appended irrespective of the depth at which they are to be placed.

A specification for imported soil is included in Appendix I.

31 Protection of Incoming Water Supply

Given the presence of made ground at the site, specific protective measures may be required by the water utility provider.

Page | 39

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe

It is recommended that proposed water supply company is consulted at an early stage to agree any protection that may be required. Proposals for protection of incoming water supplies should be finalised following reduction in site levels. Given the results of testing on the made ground soils thus far, it may be possible to demonstrate to the water supply company that no specific remedial measures are required.

32 Waste Disposal

It is anticipated that the proposed development will generate waste soils and materials will need to be removed from site as part of the construction process. Where soils are to be disposed off-site, it is the duty of the waste producer, in this case Chartway Group to ensure that all waste is disposed of appropriately and that any that is sent to landfill is sent to an appropriately licensed one. All waste sent to landfill must be classified and must be pre-treated. The form of pre-treatment should be documented in the Site Waste Management Plan. There are various forms of pre-treatment that are acceptable. In this case it could include “reduction in volume”, which could be achieved by segregating the Made Ground and re-using part of it on site. Where made ground soil is to be re-used on site then it is recommended that this is carried out under the CL:AiRE Code of Practice for re-use of soils16. It is considered that the soils would likely be classified as inert for waste disposal purposes, however it is recommended that this is confirmed with a haulier/receiving site. Further testing and inspection of soils will be required to confirm waste classification of material leaving the site. It is strongly advised that detailed discussions be held with remediation/groundworks contractors and that receiving landfill sites are identified in advance of commencing any waste removal.

32.1 Definition of Waste – Industry Code of Practice A potential alternative to disposal at landfill is for the reuse of materials on or off site. It is proposed that in the event that any materials are to be re-used on or off site then this process would be certified in accordance with the revised development industry waste code of practice published by CL:AiRE in Spring 2011.

16 The Definition of Waste: Development Industry Code of Practice. Version 2 2011. Cl:aire

Page | 40

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe

A detailed assessment would need to be undertaken to demonstrate that materials are both fit for purpose and that there is demonstrable requirement for the materials at the final destination.

33 Geo-environmental Conclusions and Recommendations

The following geo-environmental conclusions and recommendations are made:-

 The ground investigation encountered made ground to depths of up to 1.5m below ground level.  The chemical analysis completed has not identified any significant contamination within the underlying soils.  There is considered to be a potential for hitherto as yet unidentified contamination to be recorded during the construction process, particularly beneath the existing buildings. It is recommended that stripped formations are inspected by suitably qualified person and tested once exposed.  Protection of incoming water supply may be required and it is strongly recommended that discussions are held with incoming water supply providers at an early stage to confirm requirements they may have.  If the testing records conditions worse than those reported on herein, a revised risk assessment should be undertaken and remediation measures agreed with regulators and warrantors.  No specific remediation is considered to be required at the present time.  Natural soils on site that are to be excavated as part of the development process may be suitable for reuse elsewhere subject to completion of appropriate risk assessments. The transfer of any materials leaving site should be fully documented and undertaken in accordance with the Develop Industry Waste code of practice (CL:AiRE 2011).  If soils are to be disposed off-site they are expected to be classified as non-hazardous – this will need to be confirmed by further testing.  Any imported soils brought onto site should be verified clean and suitable for use.

This report is confidential to the Client, and Leap Environmental Ltd accepts no responsibility whatsoever to third parties to whom this report, or any part thereof, is made known, unless formally agreed by Leap Environmental Ltd beforehand. Any such party relies upon the report at their own risk. Unless explicitly agreed otherwise in writing, this report has been prepared under LEAP’s standard terms and conditions, as included in the quotation for this works.

This report has been prepared by Leap Environmental Ltd on the basis of information received from a variety of sources which Leap Environmental Ltd believes to be accurate. Nevertheless, Leap Environmental Ltd cannot and does not guarantee the authenticity or reliability of the information it has obtained from others.

Leap Environmental Ltd has used all reasonable skill, care and diligence in the design and execution of this report, taking into account the manpower and resources devoted to it in agreement with the Client. Although every reasonable effort has been made to obtain all relevant information, all potential contamination, environmental constraints or liabilities associated with the site may not necessarily have been revealed. LEAP cannot be held responsible for any disclosures or changes in regulation that are provided post production of this report, and will not automatically update the report.

The conclusions reached in this report are necessarily restricted to those which can be determined from the information consulted, and may be subject to amendment in the light of additional information becoming available. These conclusions may not be appropriate for alternative schemes.

The extent of the exploratory holes, laboratory testing and monitoring undertaken may have been restricted due to a number of factors including accessibility, the presence of buried or overhead services, current development and site usage, timescales or clients specification. The exploratory holes only assess a small proportion of the site area with respect to the site as a whole, and as such may only provide an overall assessment of ground conditions on site. The presence of hotspots of undisclosed contamination or exceptional and unforeseen ground conditions cannot be discounted. Eurocode 7 gives guidance on the type of sampling, sample quality, number and spacing of intrusive investigations, and number of laboratory tests required. It is intended that the Geotechnical Information section of this report will fulfil the general requirements of the Ground Investigation Report as set out in section 6 of Eurocode717, although this is subject to the restrictions imposed on the investigation as listed above. For geotechnical design, Eurocode 7 requires the Geotechnical Design Report to address both the geotechnical and

LE/QMS/Doc 7/5-1 Issue 5 LP 001170: Roselands, Seddlescombe structural aspects of the geotechnical design for both the limit and serviceability states. The Geotechnical Appraisal section of this report will not meet the requirements of a Geotechnical Design Report (GDR), and should therefore be used for preliminary guidance only.

The presence of asbestos may be noted during the site walkover survey, intrusive investigations and/or from the results of contamination testing. However, this report does not constitute an asbestos survey. On this basis, the presence of asbestos on site cannot be discounted and a full asbestos survey should be undertaken.

Introduction

The Environment Act 1995 has made site sensitivity a key issue, as the legislation pays as much attention to the pathways by which contamination could spread, and to the vulnerable targets of contamination, as it does the potential sources of contamination. For this reason, Landmark's Site Sensitivity maps and Datasheet(s) place great emphasis on statutory data provided by the Environment Agency/Natural Resources Wales and the Scottish Environment Protection Agency; it also incorporates data from Natural England (and the Scottish and Welsh equivalents) and Local Authorities; and highlights hydrogeological features required by environmental and geotechnical consultants. It does not include any information concerning past uses of land. The datasheet is produced by querying the Landmark database to a distance defined by the client from a site boundary provided by the client.

In the attached datasheet the National Grid References (NGRs) are rounded to the nearest 10m in accordance with Landmark's agreements with a number of Data Suppliers.

APPENDIX D – QUALITATIVE RISK ASSESSMENT MODEL

Qualitative Risk Assessment Model

QUALITATIVE RISK ASSESSMENT MODEL

The Qualitative Risk Assessment Model used is based upon that developed by the NHBC1 (2008) which is itself developed from (DOE, 1995) A Guide to Risk Assessment and Risk Management for Environmental Protection; and the Statutory Guidance on Contaminated Land (Defra, September 2006). The methodology is based on that presented in CIRIA2 C552 2001; but differs in terms of the definitions of classification of consequence, which include a consideration of immediacy of hazards.

The key to the classification is that the designation of risk is based upon the consideration of both:

A) the magnitude of the potential consequence (i.e. severity) [takes into account both the potential severity of the hazard and the sensitivity of the receptor]

B) the magnitude of probability (i.e. likelihood) [takes into account both the presence of the hazard and receptor and the integrity of the pathway]

These are defined in the tables on the following pages:

Table 1 Classification of Consequence

Description of the classified risks

Very high risk

There is a high probability that severe harm could arise to a designated receptor from an identified hazard at the site without remediation action OR there is evidence there severe harm to a designated receptor is already occurring. Realisation of the risk is likely o present a substantial liability to the site owner/or occupier. Investigation is required as a matter of urgency and remediation works likely to follow in the short term.

High risk

Harm is likely to arise to a designated receptor from an identified hazard at the site without remediation action. Realisation of the risk is likely to present a substantial liability to the site owner/or occupier. Investigation is required as a matter of urgency to clarify the risk. Remediation works may be necessary in the short term and are likely over the longer term.

Moderate risk

It is possible that harm could arise to a designated receptor from an identified hazard. However, it is either relatively unlikely that any such harm would be severe, and if any harm were to occur it is more likely, that the harm would be relatively mild. Further investigative work is normally required to clarify the risk and to determine the potential liability to site owner/occupier. Some remediation works may be required in the longer term.

Low risk

It is possible that harm could arise to a designated receptor from identified hazard, but it is unlikely at worst, that this harm if realised would normally be mild. It is unlikely that the site owner/or occupier would face substantial liabilities from such a risk. Further investigative work (which is likely to be limited) to clarify the risk may be required. Any subsequent remediation works are likely to be relatively limited.

Very low risk

It is a low possibility that harm could arise to a designated receptor, but it is likely at worst, that this harm if realised would normally be mild or minor.

No potential risk

There is no potential risk if no pollution linkage has been established.

Definitions

Hazard A property or situation which in certain circumstances could lead to harm.

[The properties of different hazards must be assessed in relation to their potential to affect the various different receptors]. Risk A combination of the probability or frequency of the occurrences of a defined hazard AND the magnitude of the consequence of that occurrence. Probability The mathematical expression of the chance of a particular event in a given period of time [e.g. probability of 0.2 is equivalent to 20% or a 1 in 5 chance]. Likelihood Probability; the state or fact of being likely.

Consequences The adverse effects (or harm) arising from a defined hazard which impairs the quality of the environment or human health in the short or longer term. Pollution Linkage An identified pathway is capable of exposing a receptor to a contaminant and that contaminant is capable of harming the receptor.

Page 3 Preliminary Geotechnical Risk Register LP01170: Roselands, Seddlescombe

Geotechnical risk is the risk to building and construction work created by the site ground conditions. The Preliminary Geotechnical Risk Register has been compiled to provide an assessment of the likely risks that may impact on the proposed development based on the results of the desk study, and should be used to specify the type and extent of the intrusive investigation and testing undertaken, and to identify potential mitigation measures to control the risk to an acceptable level.

The inclusion of a risk in the register does not indicate that the risk is present, rather the likelihood of mitigation measures being required due to that risk, based on the available data. Equally, a risk classified as low indicates that mitigation measures are unlikely to be required for the hazard identified based on the available data.

The risk register should be developed and refined throughout the design process such that it will enable the management of geotechnical risk.

The Geotechnical Risk Register has been developed in accordance with the guidance presented in ICE/DETR Document "Managing Geotechnical Risk" (2002). The degree of risk (R) is determined by assessing the likelihood of a hazard (L) occurring and the effect of the hazard (E) on the project (R=LxE). The effect may be measured in one or more aspect e.g. increased cost, delays in the program, health and safety etc. The scale of the likelihood, effect and risk are determined as follows:‐

Likelihood of Occurrence Effect of Hazard Degree of Risk Scale Likelihood Chance Scale Effect Increase in Degree of Risk Level Action required cost or time Risk

4 Probable >1 in 2 x 4Very High>10% = 1-4 Trivial None 3 Likely 1 in 10 to 1 3High4-10% 5-8 Significant Consider cost effective solutions or improvements at no extra in 2 cost 2 Unlikely 1 in 100 to 1 2Low1-4% 9-12 Substantial Work must not start until risk has been reduced. Additional in 10 resource required 1 Negligible <1 in 100 1Very Low<1% 13-16 Intolerable Work must not start until risk has been reduced. If risk can not be reduced, project should not proceed.
