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. 0 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 degrees f

< use 3/4 in. plywood for sheathing and 2"x 4" lumber for studs and wales.
< assume that the lumber can be used 4 times.
< 3,000-lb form ties are available.
< assume that 12 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 $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 () = $27.25
foreman = $40.00
