Estimate the direct cost of materials, equipment and labor for wood forms for a concrete foundation wall of a building whose outside dimensions are 46 ft. 6 in. wide, 88 ft. 0 in. long, 9 ft. 8 in. high, and 9 in. thick. Concrete will be vibrated as it is placed at the rate of 6 ft/hour under minimum temperature of 70 F
Use 3/4 in. plywood for sheathing and 2"x4" lumber for studs and wales.
Assume that the lumber can be used 5 times.
3,000-lb form ties are available.
Assume that 10 lb of nails will be required per 1,000 fbm
Form oil will be applied at the rate of 400 sf/gal
A power saw will be used at the rate of $3.75/hour
Cost of materials are: Lumber, per 1,000 fbm, $480.00 Nails, per lb, $0.98 Form ties, per 100, $37.50 Tie clamps, per 100, $48.00 Form oil, per gallon, $7.85
Labor production rate for making, erecting and stripping the job-built plywood wall forms is 4 man-hours per 100 SFCA. Select your crew combination.
