Assignment Help:

An electrical contractor is preparing to place the duct bank concrete encasement for the high voltage feeders between manhole # 11 and # 12, total distance is 323-ft. The duct bank is 2-ft x 3-ft and holds nine 4.5-in Schedule 80 PVC conduits. The amount of concrete to be ordered is most nearly:

Solution:

Nominal 4-in Schedule 80 PVC pipe is 4.5-in O.D. 

Total Volume = 2' x 3' x 323' = 1938-ft3 / 27-ft3/CY = 71.77-yd3

 Total Deduct = 9 x (π ((4.5"/12")/ft)2)/4 x 323' = 321-ft3 / 27-ft3/CY = 11.89-yd3

Total Concrete = 71.77-yd3 - 11.89-yd3 = 59.88-yds3
