How deep is the utility line?
The installation of Utility lines is usually regulated by local building codes, electrical codes, etc. However, site conditions vary, and lines are seldom installed exactly as they should be.
While Pipe & Cable Locate Equipment is capable of measuring the depth of connected lines, depth measurements are notoriously erroneous, and can be affected drastically be things like soil density, surface material, and even humidity. Therefore, the depths of utility lines are seldom given on locate reports, and are to be taken cautiously at best.
Reported depths do not relieve the contractor from the obligation to excavate within 1m horizontally of marked utility lines by hand, without mechanical aid. This cannot be stressed enough.
