Trenching and backfill with power equipment. Using a 55 HP wheel loader with integral backhoe to
excavate utility line trenches and continuous footings where soil is piled adjacent to the trench. Linear
feet (LF) and cubic yards (CY) per hour shown are based on a 2-man crew. Reduce productivity by 10 to
25 percent when soil is loaded in trucks. Shoring, dewatering and unusual conditions will increase these
costs. Add the cost of equipment rental.
