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.

Question

A timber pile of length 8 m and diameter
0.2 m is driven with a 20 kN drop
hammer, falling freely from a height of
1.5 m. The total penetration of the pile in
