Estimate the direct cost of materials, equipment and labor for wooden forms for a concrete foundation wall of a building whose outside dimensions are 64 ft. 6 in. wide, 108 ft. O in. long, 9 ft. 8 in. high, and 9 in. thick. Concrete will be vibrated as it is placed at the rate of 4 ft/hour at the 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 4 times. 3,000-1b form ties are available. Assume that 12 lb of nails will be required per 1,000 fom Form oil will be applied at the rate of 400 sf/gal A power saw will be used at the rate of $9.75/hour Cost of materials are: Lumber, per 1,000 fbm, $580.00 Nails, per lb, $1.98 Form ties, per 100, $47.50 Tie clamps, per 100, $38.00 Form oil, per gallon, $8.95 * <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 (i.e., # Carpenters and #Laborers). Cost of Labor: ✓ Carpenters = $38.50 ✓ Laborers (Helpers) = $27.25 ✓ Foreman = $40.00
