GCG undertook a desk study investigation for the St Helen’s Place part of the site, provided a scope for the intrusive ground investigation of the full site, monitored and advised the GI contractor throughout the on-site investigation works, and undertook the geotechnical interpretation of the factual data. GCG also provided guidance and advice with respect to the options for foundations, the excavation retaining walls, and all underpinning of adjacent structures where necessary. This involved close co-operation with a range of other experts including third party party-wall surveyors, archaeologists and built heritage specialists. In addition, GCG have looked at issues of ground movement and potential building damage resulting from the development, and advised on measures to minimize such movements and damage.
