Wall footing, grade beam or tie beam forms (cont.) These figures assume nails, stakes and form oil costing \$.25 per square foot and 2.5 board feet of lumber are used for each square foot of form in contact with the concrete (SFCA). To calculate the quantity of formwork required, multiply the depth of footing in feet by the length of footing in feet. Then double the results if two sides will be formed. For scheduling purposes, estimate that a crew of 5 can lay out, fabricate and erect 600 to 700 SF of footing, grade beam or tie beam forms in an 8-hour day. Reinforcing bar supports for footing, grade beam and tie beam formsReinforcing bar supports for footing, grade beam and tie beam forms. Bars suspended from 2" x 4" lumber, including stakes.

When integral starter walls are formed, forms will usually be required at the ends of each wall or footing. These are usually called bulkheads or pour-stops. These figures assume the use of 1.1 SF of 3/4" plyform per SFCA plus an allowance of \$0.25 per SFCA for nails, stakes and bracing 1 use F5@.150 SFCA 1.63 7.11 8.74 3 uses F5@.120 SFCA .94 5.68 6.62 5 uses F5@.100 SFCA .80 4.74 5.54
 Column footing or pile cap forms These figures include nails, stakes and form oil and 3.5 board feet of lumber for each square foot of form in contact with the concrete. For scheduling purposes, estimate that a crew of 5 can lay out, fabricate and erect 500 to 600 SF of square or rectangular footing forms in an 8-hour day or 350 to 450 SF of octagonal, hexagonal or triangular footing forms in an 8-hour day.

Includes cost of nails, stakes, bracing, and form oil and 1.1 SF of 3/4" plyform for each SF of column base or dowel support. No anchor bolts included 1 use F5@.150 SF 1.63 7.11 8.74 3 uses F5@.100 SF .94 4.74 5.68 5 uses F5@.090 SF .80 4.26 5.06
 Slab-on-grade forms These costs assume nails, stakes, form oil, and accessories are used for each board foot of lumber. Note that costs listed below are per linear foot (LF) of form. Figures in parentheses show the average square feet of contact area (SFCA) per linear foot of form. Use this figure to convert costs and man hours per linear foot to costs and manhours per square foot. For scheduling purposes, estimate that a crew of 5 will lay out, fabricate and erect the following quantities of slab-on-grade edge forms in an 8-hour day: Slabs to 6" high at 615 to 720 LF. Slabs over 6" to 12" high at 450 to 500 LF Slabs over 12" to 24" high at 320 to 350 LF. Slabs over 24" to 36" high, 240 to 260 LF Edge forms to 6" high, 1.5 BF per LF of form (.5 SFCA per LF) 1 use F5@.065 LF 1.17 3.08 4.25 3 uses F5@.061 LF .71 2.89 3.60 5 uses F5@.055 LF .62 2.61 3.23 Edge forms over 6" high to 12" high, 2.25 BF per LF of form (average .75 SFCA per LF) 1 use F5@.090 LF 1.62 4.26 5.88 3 uses F5@.086 LF .94 4.07 5.01 5 uses F5@.080 LF .80 3.79 4.59
