TIT: The soil in a borrow pit has a void ratio of 0.90. A fill of volume 20000 m³ has be constructed with an in place dry density of 19.2 kN/m³. If the owner of borrow pit to be compensated t rate 2.5 per cubic metre of excavation, determine the cost of compensation. Take G = 2.68, Yw = 9.81 kN/m³.

Pricing Excavation and Backfill

Backfill, in construction, is the activity of returning the soil and gravel that are removed during building construction or using them again to toughen and support the foundation of the building or any other structural component.
