Total filling 802.2
_Cost_
The cost of excavation in sandy soil, taken from _Estimating and
Calculating Quantities_, Part 1, is 53 cents per cubic yard. The cost
of filling, including tamping, may be taken as about one-third that of
excavation, or, say, 18 cents per cubic yard.
_Summary_
Excavation, 14,296.2 cu. ft. = 529.5 cu. yd.,
at 53 cents per cubic yard $280.64
Filling, 802.2 cu. ft. = 29.7 cu. yd.,
at 18 cents per cubic yard 5.35
