Duct Bank takes the trench size, the number of conduits by trade size and the duct spacer settings. It gives the concrete in cubic yards less the conduit displacement, lays the conduits out in rows, counts the spacers and draws the cutaway; a second calculator gives pole base concrete.
The cutaway the Suite drew for its own example: 50 in wide by 20 in high, largest conduits on the bottom row, each row on its spacer. The example does not fit, and the drawing says so.
The report the Suite wrote for this example: the inputs, the four rows, the spacer count, both concrete figures and the cutaway, on one page.
84 spacers (4 rows x 21), pole base concrete 0.06 cubic yards, and 18.64 cubic yards for the duct bank (gross 694.4 cu ft less 191.3 displaced).
The Suite’s own example conduit counts, with the phone app’s spacer settings: 1 in between conduits, 2 in ground clearance, a spacer every 5 ft, 3 in cover.
STEP 1 OF 4The example in, before it is worked out: a 100 ft trench 50 in wide and 20 in high, the conduit counts by trade size, 1 in between conduits, 2 in ground clearance, a spacer every 5 ft, 3 in cover, and one 8 in by 5 ft pole base.
STEP 2 OF 4Worked out: 18.64 cubic yards (694.4 cu ft gross less 191.3 displaced), the warning that the conduits do not fit in 50 x 20 in, the four rows, 84 spacers, and 0.06 cubic yards for the pole base.
STEP 3 OF 4Scrolled down to the cutaway: 50 in wide, 20 in high, the conduits in four rows on their spacers, with the cover, the DOES NOT FIT line and the flotation warning under it.
