Labor Costs
Excavation errors often require rework, which means paying operators, surveyors, and support crews to do the same job twice.
Time & Project Delays
Over-excavation often means waiting for extra material to arrive, stalling progress. Under-excavation requires rework and re-checking, eating up valuable time and pushing the schedule back.
Hauling Costs
Over-excavation means hauling in extra fill to correct the depth. Under-excavation often leads to rework and another round of hauling out material. Either way, you're paying for transport that could have been avoided.
