Question:
1. Given a lot size of 63 feet by 69 feet and 7 inches of topsoil to be removed, how many Cubic Yards of topsoil must be removed?
Round up answer to whole number (no decimals); do not include the units.
2. Figures 3a, 3b, and 3c in Exam 2 Supplement are for retail store foundation. The dimensions of the exterior wall (and the foundation stem wall) outside-to-outside dimensions are 88 feet in length and 59 feet in width. The dimensions for the perimeter continuous footing, the concrete stem wall, the thickened slab footings are given in Figures 3b and 3c. The overall slab dimension is given in Figure 3a. Considering an 8% waste factor, what are the total cubic yards required?

3. In Figure 1 of the Exam 2 Supplement, 6 inches of topsoil are to be removed and stockpiled. The dimensions for this building are:
L1 = 30 feet; L2 = 25 feet; L3 = 24 feet; L4 = 42 feet
The topsoil is to be removed 6 feet back from the perimeter of the building to allow for working around the building and sloping the sides of the excavation. How many bank cubic yards (BCY) of topsoil need to be removed and stockpiled?

4. Figure 2 (from Exam 2 Supplement) shows the plan for a continuous footing (dashed lines). Bearing on the footings is an 11 thick stem wall (solid lines); the wall is centered over the footings. The footings extend 11 inches beyond the wall on both sides. The depth of the footings is 14 inches. The lengths of the footings are:
L1 = 24 feet; L2 = 46 feet; L3 = 13 feet; L4 = 14 feet
Using a waste factor of 8 percent, determine the total number of cubic yards of concrete needed to pour the continuous footings shown.
