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 contractor is excavating fill material from a borrow site
to be used to construct a compacted fill foundation for a
parking garage. She has determined that 5,000
compacted cubic yards of soil are required to complete
the structural fill. The in situ density of the fill material is
110 pounds per cubic foot, the loose density is 88 per
pounds per cubic foot, and the compacted density is 125
pounds per cubic foot.
What is the percent swell for the fill material? ,
What is the percent shrinkage for the fill material?
How many loose cubic yards must be hauled in trucks
from the borrow site to construct the fill?
How many bank cubic yards must be excavated and
loaded on the trucks to construct the fill?
