Suppose that you are a Project Engineer on a Dam project. The volume of soil required at the dame site is Vd=100,000m3. The final void ratio (ed) is 0.80. Your boss, the Project Manager delegates to you the important decision of buying the earth fill from one of three suppliers. • Supplier X sells fill at OMR. 0.200/m3 with e = 0.90 • Supplier Y sells fill at OMR. 0.120/m3 with e = 2.00 • Supplier Z sells fill at OMR. 0.150/m3 with e = 1.60 Evaluate and select the best supplier based on your knowledge about soil compaction.

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.
