Site Investigation and Land Contamination
Our in house skills and experience allow us to review any site from the initial DTS through to the final remediation and validation process. Our geo-environmental investigations and reports ensure that you are provided with definitive solutions appropriate to the specific development.
PWA have a successful track record working across all sectors from commercial to residential markets, where we offer the services detailed below. We have a holistic approach producing cost effective, sustainable development solutions.
Phase I and II Investigations
We have the broad depth of experience to take sites from the initial desk study (viability) stage through to detailed site investigation, including investigations for geological and mining appraisals, geotechnical investigations, contaminated land, slope stability and hazardous gas risk assessments to name a sample
Remediation & Validation
Comprehensive design and reporting on remediation issues, including provision of Options Appraisals and Remedial Strategies and design of cover and containment systems. We also undertake supervision and validation of remediation works and supervision and design of earthworks construction including liaison with Local Authority and NHBC/insuring bodies in order to obtain regulatory approval to schemes. As part of our holistic engineering solution and value engineering we also undertake inspections and provide on-site construction advice.
Soil testing may show potentially contaminated soils on a site and developers/contractors might be inclined to follow a ‘worst case’ disposal cost route. We provide assistance to utilise best practice and the application of the most up to date CL:AIRE guidance to enable decisions to be made on the suitability of on site materials for re-use (in geotechnical or environmental terms) and appropriate treatments technology should this be required. Understanding soil (waste) management and applying the best available guidance and protocols can generate significant savings and add benefit to the scheme by minimizing cost risk.
