1.0 Introduction 1.1 Appointment

Delta-Simons Environmental Consultants Limited (‘Delta-Simons’) was instructed by NTT Communications Corporation (the ‘Client’) to prepare a Piling Risk Assessment report for of a plot of land forming part of the former Sanofi Works in Dagenham, East London which is proposed for redevelopment as a Data Centre (hereafter referred to as the ‘Site’).

The location of the Site is shown on Figure 1.

1.2 Context & Purpose

The purpose of this report is to satisfy previously expressed concerns (within condition 13 of outline planning permission 15/00951/OUT) that the ground conditions are such that penetrative pilling work on the site is likely to have the potential to introduce pollutants or provide a pollutant pathway to the aquifer beneath the site.

It is understood the proposed development is to comprise a data centre.

For information on the Site setting, and details of intrusive investigations completed at the Site, this Piling Risk Assessment should be read in conjunction with Delta-Simons’ reports as follows:

▲ Preliminary Risk Assessment, NTT Communications Data Centre, London East Business and Technical Park, Project No. 17-1150.01, dated January 2018.

The assessment has been carried out in conjunction with the guidance and information provided in the following documents:

▲ National Groundwater and Contaminated Land Centre: Piling into Contaminated Sites, Environment Agency, undated; and

▲ Piling and Penetrative Ground Improvement Methods on Land Affected by Contamination: Guidance on Pollution Prevention, Environment Agency, dated May 2001.

1.3 Limitations

The standard limitations associated with this assessment are presented in Appendix A.



2.0 Proposed Development and Planning Requirements 2.1 Proposed Development

The proposed development comprises the erection of two data centre buildings (B8 Use Class), with ancillary plant, offices, gatehouse, electrical sub-stations, fuel storage, car parking, site fencing, landscaping and other associated works.

2.2 Planning Background

Outline planning permission (11/01044/OUT) on the wider site was granted by the London Borough of Barking & Dagenham in March 2012 for:

“Permission for Mixed use redevelopment comprising erection of up to 30,000 m2 of buildings (Use classes B1(c), B2, B8, D1), retention and re-use of 41,637 m2 of buildings (Use classes B1, B2, B8, D1) including up to 3,500 m2 healthcare building (Use class D1), erection of 9,816 m2 training centre (Use class D1), 9,276 m2 supermarket including petrol station, 80 bed hotel and restaurant (Use class C1) and 2 floodlit synthetic turf football pitches with associated landscaping and parking.”

In February 2015, a replacement planning permission was issued as a result of a s73 planning application to vary Conditions 5 (Approved Parameter Plans) and 24 (Car Parking) (14/00959/OUT) which relocated the position of the hotel element and increased the total number of car parking spaces accessible from Rainham Road South from 700 spaces to 763. A further adjustment to the consent (Conditions 5 and 24) was made in July 2015 which updated the Parameter Plans to reflect an amended site layout, size of buildings and to increase the allowable building heights on Areas 3, 4a & 4b from 12m to 15m. Condition 24 was amended to increase the amount of car parking spaces in areas 3, 4a and 4b from 120 to 147.

An application for the Approval of Reserved Matters (Appearance, Scale, Layout, Access & Landscaping) for the Erection of Units A, B, C, D1, D2, D3 & the Medical Centre within Areas 4a & 4b was approved on 10 October 2016. The approval of the relevant outline conditions was submitted to and approved by the Council on 22 November 2016. The approved development was partially implemented on 10 April 2017 with Units A & C constructed to shell level, with the platform for Unit B completed. Development has paused on these buildings pending discussions with the Council regarding the potential re-purposing of these buildings for film studio use.

Elsewhere on the former Sanofi site further planning permissions have been granted for a public house (constructed), a hotel (under construction), a supermarket (now lapsed), the delivery of the ELUTEC school (constructed) and the delivery of a costa coffee house (pending).

In this context the application site to which this scheme relates currently benefits from a combination of an outline and partially discharged reserved matters and conditions for three warehouses, a medical centre and a training centre for the London Fire Brigade with ancillary parking, roads and landscaping. These elements will not now be implemented and instead this eastern extremity of the wider former Sanofi site is proposed to deliver two data centre buildings with ancillary infrastructure.



3.0 Summary of Land Contamination Assessments 3.1 Findings of Investigations

The key findings of the Delta-Simons Preliminary Risk Assessment, London East Business and Technical Park, Project No. 17-1150.01, dated January 2018 are summarised below.

3.1.1 Site Details

The Site comprises an area formerly occupied by chemical manufacture facilities (agrochemical and pharmaceutical) and a landfill (D44). Now non-operational, with all buildings demolished having undergone remediation and groundwater monitoring under the supervision of ARCADIS. A Permeable Reactive Barrier (PRB) is present along the southern boundary adjacent to the railway line, installed by Sanofi to prevent off-Site migration of contaminants towards sensitive receptors.

3.1.2 Geology, Hydrology and Hydrogeology

The Made Ground encountered across the majority of the Site was typically in the range of 1 m to 3 m thick with greater thicknesses encountered in the area of the D44 Landfill. River Terrace deposits were encountered below the Made Ground in the majority of locations and are typically 3 m to 5 m in thickness. A greater thickness of River Terrace Deposits was encountered in the vicinity of the D44 Landfill to a maximum depth of 14.8 m bgl generally comprising very clayey sand. This is considered to be a potential scour hollow which was further investigated and reported in the Scour Hollow Investigation report November 2009 which concluded that the London Clay had not been breached and inferred that there was still up to 10 m of London Clay beneath the scour hollow and above the underlying Lambeth Group and deeper Chalk aquifer.

An historical BAE Abstraction Well Decommissioning Report relating to the former chemical manufacture facilities indicated that one of the four former abstraction wells was situated in close proximity to the Site where there was approximately 5 m of Made Ground, 20 m of London Clay and 35 m of Lambeth Group/ Thanet Sand deposits (Secondary A Aquifers) with Chalk (a Principal Aquifer) encountered at approximately 60 m depth below ground level (bgl).

The Site lies within a predominantly commercial/industrial area. The superficial deposits beneath the Site are River Terrace Deposits (Secondary A Aquifer) underlain by the London Clay Formation (Unproductive Strata) and at deeper depths, the Chalk (Principal Aquifer). The nearest surface water feature is a pond, located approximately 5 m east. The Beam Valley Country Park is located approximately 30 m to the south. The overall environmental sensitivity of the Site’s setting is considered to be moderate.

In view of the recent remediation works, controls and validation work which has been undertaken to shallow soils and underlying Secondary A Aquifer associated with the River Terrace Deposits (as agreed with the Environment Agency (EA)); the primary risk driver for this piling assessment is aimed to assuring the proposed penetrative construction works are (demonstrably) designed to ensure there is no resultant unacceptable risk to the underlying Lambeth, Thanet Sand and Chalk aquifers by virtue of the potential for the creation of new/ additional pollution pathways to these receptors by the proposed works.

3.2 Environmental Findings & Recommendations

The Site area comprises an area formerly occupied by chemical manufacture facilities (agrochemical and pharmaceutical) and a landfill (D44). Now non-operational with all buildings demolished and having undergone remediation, monitoring and PRB maintenance by Sanofi/ ARCADIS.

A summary of the contamination risk assessment undertaken by Sanofi/ ARCADIS is outlined below:

▲ Site-Wide DQRA selected 55 representative contaminants of concern;

▲ The DQRA was undertaken on the assumption that the PRB was not present (this approach was supported by the EA);

▲ Off-Site residential receptors to the south of the Site, approximately 150 m at their closest point, were considered by the DQRA;



▲ Exceedances of Site Specific Assessment Criteria relevant to the Site were identified in terms of both Human Health (on-Site) and environmental receptors (on and off-Site);

▲ Potential off-Site risks to neighbouring residents were identified with respect to recorded concentrations of contaminants in groundwater, but there should be a negligible risk to off-Site residential receptors following remediation;

▲ DQRA identified the requirement for remediation of soils and groundwater and a Remediation Strategy was developed and agreed with the EA; and

▲ The aim of the remediation was to address contamination in soil and groundwater with the ultimate aim being to achieve agreement with the EA to decommission the PRB.

Remediation targets and methodologies (and validation plans) were agreed with the EA and were focussed on (in general terms):

▲ Contamination mass reduction to meet applicable Human Health criteria;

▲ 70-90% reduction in the concentrations of target compounds in groundwater averaged over the network of validation monitoring wells; and

▲ Given the concentrations and complexity of the contaminants involved this approach is considered to be appropriate with validation based on a practical demonstration of significant betterment backed up with validation monitoring.

Delta-Simons considers that the remediation works have been completed in accordance with the relevant Remediation Implementation Plans and have achieved the aims and objectives; the contaminant load appears to have been reduced significantly (90%). Some locations have not fully met all validation criteria, although in the context of the full data set and distribution these localised areas are not considered significant by ARCADIS - though in many cases one of the supporting justifications for this conclusion is that the ‘hotspot’ is isolated and wells closer to the receptor/ boundary are clean, therefore, indicating contamination is not migrating.

The validation reports for Back Plot A and Back Plot B have been accepted by the LA and EA. Likewise, the PRB has been cleared for decommissioning by the LA subject to conditions to ensure that no decommissioning is to take place until a Long Term Monitoring and Maintenance Plan in respect to contamination is in place, and that no previously unidentified contamination is encountered during decommissioning of the PRB.

Development specific mitigation measures will be required against risks associated with residual asbestos contamination (located in the area of the Former D44 landfill) following guidance stated in ‘HSG 66 Protection of Workers and the General Public during Redevelopment of Contaminated Land’ during development works and using personal protective equipment (PPE). All new service trenches should be backfilled with clean Site won or imported materials and/ or the use of upgraded pipework may be required subject to agreement with the relevant utility provider. Site end users will be protected against any such risks due to the nature of the proposed development, comprising either building footprint or hardstanding. Any landscaped areas/ verge dressing, should be capped with an appropriate topsoil/ subsoil to provide a suitable growing medium which will also protect Site users from any residual contamination in underlying soils, which should be separated by a geotextile marker membrane and capillary break layer.

Delta-Simons has completed a three-month gas monitoring programme across the Site on an approximately 50 m grid, to assess the requirements for ground gas protection measures in ground floor structures, which classified the Site as Characterisation Situation 2 – low risk. It is recommended that gas protection measures be increased to include a hydrocarbon/ VOC resistant membrane due to the elevated VOC’s recorded.

It is considered that following the completion of soil and groundwater remediation and PRB decommissioning (which is the responsibility of Sanofi/ ARCADIS), and implementation of mitigation measures comprising importation of a topsoil capping layer, gas protection measures, and upgraded water supply pipes, that no plausible pollutant linkages would remain with respect to Human Health.

Following an assessment of risks and liabilities, an overall Low risk is considered for the Site and surrounding area in terms of risk to Human Health and controlled waters in the context of the proposed end use of the Site.



3.2.1 Recommendations

A geotextile membrane and minimum 600 mm of certified suitable for use top soil and subsoil overlying a geotextile marker membrane and capillary break layer will be incorporated into all new landscaped areas.

Ground gas protection measures, in accordance with BS8485:2015, are required for any new buildings proposed at the Site (upgraded to include a hydrocarbon/ VOC resistant membrane).

The local water authority will require upgraded potable water pipes and/or dedicated isolated clean sewer runs in order to mitigate any residual risks associated with the remediated Site.

A ‘Hotspot’ protocol will be in place for groundworkers and sub-surface maintenance workers to act upon should areas of suspected contamination be identified during the groundworks. Appropriate budget allowances should be included in the redevelopment costs to deal with any additional contamination identified during development works. Some isolated ‘hotspot’ locations have not fully met all validation criteria, although in the context of the full data set and distribution these localised areas are not considered significant.

Any ground/ construction workers who are required to undertake sub-surface work at the Site will be made aware of the possibility of encountering localised contamination (specifically residual asbestos within D44 Landfill area) and safe working practices and use of appropriate PPE should be implemented to mitigate the risks.

It is understood that earthworks will be required in order to form developable platforms, and to enable obstruction removal works to facilitate piling (to be undertaken in accordance with this Piling Risk Assessment. A suitable Materials Management Plan will be developed, giving consideration to the waste hierarchy, in order to reduce the amount of material requiring off-Site disposal. If considered necessary, a waste classification exercise could be completed in order to determine the likely disposal costs of soils requiring off-Site disposal.



4.0 Proposed Piling Works The works comprise the construction of foundation piles for the proposed development. The general scope of works will comprise:

▲ Piles will utilise continuous flight auger systems;

▲ Pile design is cognisant of the prevailing ground conditions, and which have been supported by specific investigation arranged by the structural/ geotechnical engineers. The Engineer has confirmed that a minimum of 5 m of low permeability strata (London Clay and cohesive Lambeth Group soils) will remain below the base of piles, thus protective of the underlying Chalk Aquifer at depth.

Details of piles foundation proposed are outlined on Capita piling design information included as Appendix B.



5.0 Selected Piling Methods 5.1 Continuous Flight Auger (CFA) Piles

The CFA method will involve constructing the piles with a CFA piling rig which has a full length hollow stem auger. The pile will be bored in a continuous downward movement to the founding depth of the pile. As the auger rotates spoil will travel upwards, keeping the flights of the auger full of spoil, at all times. Once the auger has reached the founding depth, sand-cement or concrete is pumped down the hollow stem at a controlled rate as the auger is steadily withdrawn. A steel reinforcement cage is inserted into the liquid concrete immediately after.



6.0 Conceptual Site Model In accordance with current UK best practice and in line with the Environment Agency guidance on piling on land affected by contamination, the potential environmental hazards (with respect to groundwater) created by piling on the Site have been considered in the context of the following CSM risk assessment, based on the source-pathway-receptor principle.

6.1 Sources

Delta-Simons has reviewed available information and highlighted the following as potential sources of contamination based on the ground investigation (relevant to controlled waters):

▲ Residual contaminant concentration in soils and shallow Secondary A groundwater following successful remediation of the Site, protective of human health and other relevant controlled waters.

6.2 Pathways

The underlying shallow groundwater beneath the Site (Secondary A Aquifer), is not considered to be in hydraulic continuity with the deeper Chalk aquifer due to the presence of low permeability London Clay and Lambeth Group strata, and as such, a preferential pathway could be created by piling. As indicated in the pile design, it has been assured that at least 5 m of low permeability London Clay will remain below the base of piles. In addition, it is noted that post development, the use of significant hardstanding will reduce the overall infiltration through the fill materials.

6.3 Receptors

Secondary A Aquifer (Lambeth Group and Thanet Formation) and Principal Aquifers (Chalk Formation) below the London Clay Formation (Unproductive Strata).



7.0 Plausible Pollutant Linkages From the above CSM, the following plausible pollutant linkages have been identified, in relation to the proposed piling works on the Site:

Plausible Pollutant Linkages

Source(s) Pathway(s) Receptor(s)

Residual contaminant concentration in soils and

groundwater following successful remediation of the Site

Vertical migration of leachable contaminants, mobilised by the action of piling through soils.

Secondary A and Principal Aquifers at depth.



8.0 Piling Risk Assessment Based on the above identified plausible pollutant linkages, the following assessment of the risk that piling presents is discussed below:

8.1 Continuous Flight Auger (CFA) Piles

As described in Section 5.0 above, CFA piling ensures that the sides of the hole are continuously supported by the soil-filled auger. At the completion of boring (ensuring at least 5 m of low permeability London Clay remains below the base of piles), concrete is continuously injected into the void created by the extraction of the auger (resulting in close contact with the surrounding soil), closing any pathway that might be created at this point.

The EA guidance on piling on land affected by contamination states that “provided the pile is formed or placed in intimate contact with the surrounding soil there should be no formation of preferential pathways”. No permanent preferential pathways or pollution sources are therefore deemed created as a result of CFA pile construction at the Site.

Consistent with the Environment Agency’s position that 5 m of low permeability soils (i.e. London Clay) is of sufficient thickness to remain protective of the underlying aquifers for other developments within the London basin, the identified receptors are not considered to be at any unacceptable risk.

Therefore, it is considered that the risk of increased contaminant impact to the underlying deeper Secondary A and Principal Aquifer from the CFA piling proposed is negligible.



9.0 Conclusion This piling risk assessment considers that there is very low to negligible risk of mobilising significant contamination through a preferential pathway to the underlying deeper Secondary A and Principal Aquifer with the use of CFA piles proposed.

As such the overall risks to controlled waters (deeper bedrock aquifers) associated with CFA piling at the Site are considered to be to be negligible.
