Land Contamination Desk Study Assessment and Site Investigation Report
Intrusive ground investigations typically comprise excavating trial pits and/or drilling boreholes so that the underlying ground conditions can be inspected and samples retrieved for chemical and/or geotechnical testing.
Our investigations are supervised by experienced geo-environmental and/or geotechnical personnel in order to maximise the data collected, and record the ground conditions exposed by the exploratory holes.
JOMAS Associates Ltd provide Phase 1 Land Contamination Desk Studies, mainly, for four reasons;
The Site Walkover allows the site and its surroundings to be inspected. It includes an assessment for potential indicators of contamination, such as distressed vegetation, discoloured soils, polluted water and waste materials (including asbestos if present). Potential ground problems can thus be identified during the walkover.
To support the land pre-purchase due diligence process, we conduct site appraisals to determine potential abnormal development costs. We identify worst case remediation costs for dealing with identified contamination, as well as providing our client with options for minimising remediation costs to allow for a feasible development.
Jomas prepare all Phase I desk study reports in accordance with CLR11, BS10175 and BS5930 – we have not had a report rejected by a Local Authority to date.
The information from the Phase 1 Land Contamination assessment is used to develop a “Conceptual Site Model”, which forms the basis for the Phase 2 Land Contamination intrusive investigation, should one be considered necessary.
