An earth fill, when completed, will occupy a net volume of $187,000$ cy$.$ The borrow material that will be used to construct this fill is a stiff clay. In its "bank" condition, the borrow material has a wet unit weight $()$ of $129$ lb per cubic foot $($cf$),$ a water content $(\%)$ of $16\mathrm{.}5\%,$ and an in$-$place void ratio $($e$)$ of $0\mathrm{.}620.$ The fill will be constructed in layers of $8-$in$.$ depth, loose measure, and compacted to a dry unit weight $(d$ of $114lb$ per cf at a moisture content of $18\mathrm{.}3\%.$ Compute the required volume of borrow pit excavation.
