Verification of cables and pipes

It is possible to detect cables and pipes using groundradar and particularly the 3D-radar, and to relate their real position to the expected position, as recorded in the KLIC drawings. These are then supplement with cables, pipes and obstructive objects that were detected but have not yet been registered. In many cases, the KLIC drawings are not entirely accurate or incomplete. See for instance, the figure below, showing a comparison of radar scans and a test trench excavated on the same trace.
