An 8 m thick clay layer is located between two layers of sand. Also there is a thin drainage layer within clay layer at a depth of 3 m from top. If a structure is constructed above clay layer, the time required in days to attain half the ultimate settlement is (Assume T, =u? is valid for whole range of consolidation.) 4 [Take C,= 4.2 x 10-2 mm2/s]

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.
