Phase II Environmental & Geotechnical Site Investigation

PBA have vast experience in carrying out Site Investigation work, specialising in holistic investigation of environmental and geotechnical issues

Where a Phase I Site Investigation has identified the potential for environmental liabilities to be present, either as a result of historic site activity, industrial accidents, or as a result of off-site activity, a Phase II Environmental Site Investigation is usually the next step.

All of our investigations comply with current UK environmental regulations, and are conducted in accordance with Environment Agency Contaminated Land Report 11 ‘Model Procedures for the Management of Land Contamination’, BS 5930:2015 ‘Code of Practice for Site Investigations ‘ and BS EN 14688-1(2002), BS EN 14689-1 (2003) and BS EN 14688-2 (2004). Where required, PBA will liaise with and obtain approval from the regulators.

The scope of a Site Investigation is unique to the circumstances of the client, and the characteristics of a site or development. In all cases PBA will establish the needs of the client, and tailor the investigation to meet these specific requirements.

A typical PBA Environmental Site investigation may include:

  • The excavation of trial pits, cable percussive boreholes, and/or window sampling
  • Well installation
  • Soil and groundwater sampling for inspection and chemical analysis
  • Ground gas monitoring
  • Quantitative environmental risk monitoring
  • Site safety plan & underground service clearance
  • Independent laboratory chemical & geotechnical analysis
  • The design and execution of remedial solutions (with regulatory approval)
  • Validation and verification

In many cases clients will require not only an assessment of the environmental issues and liabilities relating to a site, but may also require geotechnical guidance.

PBA can manage geotechnical investigations compliant with current guidance forming, either, as part of an environmental investigation, or as an entirely separate investigation. In either case,  factual and interpretive reports can be provided.
