Contamination and Coal Mining Assessment – Sheffield
BEK Enviro has recently completed a Site Investigation and Contamination Assessment at a Car Sales Garage located in Sheffield to support the redevelopment of the site for residential use. The investigation included the drilling of a series of shallow boreholes at the site to establish the risks from contamination and to provide recommendations regarding foundation design. In addition, a series of open rotary boreholes were drilled to establish the risks from shallow mining at the site. Gas and groundwater monitoring probes were installed in several boreholes to facilitate the assessment of potential risks from ground gas.
Assessment of the site investigation data indicates the risks from contamination to be low. However, the rotary investigation has encountered shallow voids at the site (2 m voids at 7 m bgl) which will require further remedial works in the form of grouting. The ground gas assessment is ongoing and will be finalised on completion of the gas monitoring regime.
