Harrison Group Environmental

Harrison Group Environmental was awarded principal contractor status by Centrica Ltd. to carry out a geotechnical site investigation for the proposed onshore electricity cable route for the Lincs offshore wind farm, from the landfall at Sutton Bridge to the receiving substation site at Walpole St. Peter. The scope included intrusive investigations (cable percussive boreholes, cone penetration testing and trial pits), sampling and laboratory testing of geotechnical soil properties including thermal resistivity, and geophysical work including seismic refraction/reflection to characterise underlying geology in areas inaccessible to plant, along with utilities surveys at proposed crossings.
