Housing
East Hoathly, Sussex
Initially commissioned by the land owner of an industrial estate to carry out a desk study and site investigation, we were subsequently appointed by the purchasing housing developer to assist with further investigations associated with site redevelopment to provide 44 residential houses.
Further investigations included a detailed gas risk assessment, preparation of a remediation action plan, on site remediation supervision, ongoing liaison with local authority and preparation of completion reports for NHBC warranty completion.
Our involvement with the project has provided significant cost savings to our client by applying site specific approach to gas risk assessment and cover system design.
Footscray, Kent
We were initially commissioned by the developer of this former car maintenance garage to advise on potential contamination and geotechnical issues relating to the site. Our involvement, as with most projects, began with the preparation of a desk study, development of conceptual model and site investigation to assess ground conditions. Development proposals were for the provision of 40 residential units with basement car park, private gardens and communal landscaped areas.
The site was contaminated with fuels associated with the former uses and is located in a sensitive groundwater area. The Environment Agency raised serious concerns relating to the fuel contamination and potential impacts to a nearby ground water abstraction point. Our proactive involvement and liaison with the regulators provided significant project savings and management of future liability relating to protection of groundwater. We prepared and agreed monitoring and remediation method statements with the regulators. Our engineers oversaw and directed remediation works on site, with an extended period of groundwater monitoring undertaken and regularly reported back to the regulators through out the remediation contract. The submission of our completion report at the end of the process ensured the development could proceed without the requirement for any ongoing groundwater treatment or monitoring.
Addiscombe Road, Croydon
The site of a former petrol filling station and car maintenance workshop, we were commissioned to carry out a full range of contamination and geotechnical investigations and assessment. Plans for the site were to provide a mix of affordable social housing with communal gardens and a block of flats to the front of the site.
Our works included undertaking a desk study and development of site conceptual model combined with the review of previous investigations carried out by others and provision of recommendations for further works.
Further works included a combined geotechnical and contamination investigation, attending meetings and corresponding with regulators, development of a remediation action plan specifying remedial requirements, onsite remediation supervision and validation and provision of a completion report documenting remedial works and obtaining regulatory sign off at the end of the development process.
Our involvement with this project provided the client with a tailored action plan, minimising costs and delays to the project from contamination whilst addressing all risks to the satisfaction of regulators.
