In estimating the cost of the concrete forms for the concrete columns, it is assumed that making and placing the concrete forms for the basement concrete columns will cost about $26.00 per thousand; the cost of stripping and resetting, $16.00 per thousand; and 3.1 square feet of lumber is required for each square foot of concrete column surface. To this average cost of 7.7 cents per square foot of concrete column surface, should be added 10 per cent for bolts, nails, waste, etc. If three sets of concrete forms are required, the second-story cost would be 16.2 cents, and the sixth story 5.9 cents, giving the average cost per square foot, of 9.1 cents. The student should remember that this lumber has a value after it has been removed from the building, and that this value should be deducted from the total cost of the concrete forms, to find the actual cost of concrete forms. Some interesting cost data are given on the cost of concrete forms used in erecting a reinforced concrete garage in Philadelphia during the summer of 1907.

The building was 53 feet wide, 200 feet long, and four stories high; also there was a mezzanine floor. Tongued and-grooved lumber 7 inch thick was used for the concrete slab concrete forms, and 1-inch plank for the beams and girders. The area of the 1,740 cubic yards of concrete covered by concrete forms was impressive. For this work, 170,000 feet, board measure, of new lumber was bought; and 50,000 feet board was used, the cost being: Since 220,000 feet, board measure, were used for the 1,740 cubic yards, there were 126 feet, board measure, per cubic yard of concrete. New concrete forms were made for each floor, except the sides of the girders, which were used over for each floor, where the sizes would admit of this being done. The props under the girders were allowed to remain in place throughout the building until the entire job was completed. The concrete forms for the roof were made entirely of the material used on the floors below. The area of concrete covered by the new lumber was approximately 80,000 square feet. This gives a cost for lumber of 6.4 cents per square foot. A force of fifteen carpenters working wider one foreman, framed, erected, and tore down all concrete forms. Laborers handled all the lumber for the carpenters, except when they were at work mixing and placing concrete.

The foreman was paid $35 per week, while the carpenters were paid an average of $4.40 for an 8-hour day. Laborers were paid 17 cents per hour, and worked a 10-hour day. Over the laborers was a foreman who received the same wages as the boss carpenter. The concrete forms for a floor were erected in from 8 to 10 days. For the framing, erecting, and tearing down of the concrete forms, the labor cost was about $3,480, which gives a cost of $2 per cubic yard. For the carrying and handling of the lumber, the cost was about $1,914, which gives a cost of $1.10 per cubic yard. This gives a total cost per cubic yard of concrete forms. This cost is high, owing to the fact that so little of the lumber was used a second time, there being only from 16 to 20 per cent so used. For the 220,000 feet, board measure, of lumber used on the job, the average cost per thousand for the concrete forms was heavy. It should be remembered that the lumber used in the concrete forms had a salvage value, for which no allowance is made in the above $2.90. Fig. 164 illustrates an adjustable clamp for holding concrete forms together. It is commonly used to hold the plank concrete forming the sides of a beam or girder in place; it is used also in clamping the opposite sides of concrete columns. It is forged from an 11 inch by -inch steel bar, and is held in place by the slotted forging, 1 inch square, by driving it tight. Concrete forms for conduits and sewers must be strong enough not to give way or to become deformed, while the concrete is being placed and rammed and must be rigid enough not to warp from being alternately wet and dry.
