A cut and fill operation requires moving 2,500 cubic yards of soil. The soil has a swell factor of 25% and a shrinkage factor of 8%. How many cubic yards must be excavated to achieve 2,500 cubic yards of compacted fill?
Correct Answer
D) 2,717 cubic yards
Required compacted fill = 2,500 cy. Accounting for 8% shrinkage: in-place volume needed = 2,500 ÷ 0.92 = 2,717 cubic yards must be excavated.
Why This Is the Correct Answer
Required compacted fill = 2,500 cy. Accounting for 8% shrinkage: in-place volume needed = 2,500 ÷ 0.92 = 2,717 cubic yards must be excavated.
