Our remit for this scheme was to evaluate a 6,000,000m2 area. Looking at potential routes for a new 400Kv circuit. Over a ten week period the teams of Rook Services survey unit were dispatched across Avonmouth where foot surveys and full GPR and GPS data was captured. The results of the data were converted into full ACAD drawings for the client to look at potential routes across the area. Rook Services adopted the very latest in electronic trial hole technology to establish some of the routes for the scheme.
