Environmental Assessments

Contaminated land from historical land uses, fly tipping and industrial/commercial activities can be found all over the UK. Such parcels of land are usually found in built up areas, where land values are high and there is significant demand for new developments such as schools, housing and open spaces.

CDS specialist environmental teams can establish historical and current land uses of parcels of land and the cost implications of the potential contamination which may be encountered. Following the initial assessment CDS can carry out a detailed Phase I Desk Study Assessment, followed by a targeted site investigation to assess the nature of the ground conditions and levels of both soil and groundwater contamination (asbestos, heavy metals, hydrocarbons) as well as the risks posed from land gas contamination. On completion of the investigation works, CDS can then advise on the best course of action concerning  the development of the site and the remedial measures which may be required to ensure that the environment, groundworkers and future end users of the site are not at risk from contamination.

Asbestos Contaminated Ground

Site Investigations are usually carried out in a phased approach, providing a bespoke solution for each site.

  • Phase 1 – Desk Study Assessment and Walkover Survey. The aim of phase 1 is to identify the potential geotechnical and contaminative risks which may impact the site based on the nature of the development. The assessment enables a specific plan of action to be designed for the for the next stage of works.
  • Phase 2 – Site Investigation Work. A targeted intrusive investigation is carried out using the information provided from Phase 1, enabling a cost efficient investigation to be undertaken ensuring that potential risks are highlighted and addressed.
  • Phase 3 – Production of remediation strategy. If the Phase 2 works identify a significant risk of contamination on site, CDS will design a site specific remedial strategy to deal with the identified contamination in the most cost and time efficient way.
  • Phase 4 – Remedial Works and Validation. Following the remediation strategy being agreed with the Local Authority, CDS can oversee and document remedial action and provide the validation report required by the planning department, ensuring works are carried out as agreed to remove the risk to the environment and the end users of the site.
