A 3D survey of this service road was carried out using laser scanning to pick up the levels, manholes, building outlines and overhead cables. GPS was used to fix the survey to OS. An as-built 3D outline model was produced as a starting point for the re-design of the road layout. A feature was the number of overhead lines that crossed the road and had to be modelled for vehicle clearance heights. The on site survey took less than one day to complete.
