An exisiting pipe near a new road development failed the roundness calibration test after the road was completed. The deformation proved so severe that the survey probe could not pass the damaged point. Therefore, two single-entry surveys (A and B) were conducted, starting at the nearest access points on each side of the damage. The two survey results were merged in AutoCAD to determine the exact strike location.

Subsequent to the measurement, the DR-4 probe was fitted with the DRC-2 modular camera unit to obtain footage of the extent of the damage.
The measurement results clearly identified the cause of the damage and the results were used in the insurance claim.
