$86.93 If union rules require a mixer engineer, deduct 0.35 (.46) hours labor time and add 0.35 (.46) hours engineer time per c.y. (cu.m). If concrete is discharged from mixer directly into a hoist concrete bucket and wheeled from a floor hoppper to place of deposit, deduct .50-hr. Labor time. For concrete roof fill on flat roofs, deduct about 10% from the above costs. On pitch or gable roofs, add 25% to 50%, depending on the steepness of slope, accessibility, etc. After the cubic yard (cu.m) cost has been computed, to obtain the s.f. (sq.m) cost, divide the c.y. (cu.m) cost by the number of s.f. (sq.m) of fill obtainable from one c.y. (cu.m) and the result will be the labor cost per s.f. (sq.m) of fill. Example: find the s.f. (sq.m) labor cost of 3" (.075 m) floor fill with a cost of $43.90 per c.y. (57.39 per cu.m). The tables on previous pages give 108 s.f. of 3" (10 sq.m of .075 m) fill obtainable from one c.y. $43.90/108 = $0.406 per s.f (57.39/10 = $5.74 per sq.m). To the above costs must be added the cost of setting screeds and all finishing operations.
