The work package for the spot footing includes the concrete for the footing,forms, the horizontal rebar in the footings, and the dowels needed to connect the footings to columns. The concrete is treated as a volumetric good,the forms for short footings (12 inches thick or less) are treated as a linear component, the form for tall footings (thicker than 12 inches) are treated as sheet goods and are measured by the square foot, and rebar is treated as a counted item. The quantity takeoff for a spot footing is shown in the following example. Determine the volume of concrete in cubic yards, the lineal feet of forms,and the rebar needed to complete 10 of the footings shown in Figure 5-1.Provide 3 inches of cover for the rebar in the footings and 2 inches of cover for the rebar in the columns. Include 10% waste in the calculated volume of concrete, and express the volume of concrete in quarter-yard increments.
