6) Determine the volume of concrete needed to complete the curb in Figure 1. The curb is 6 inches wide by 18 inches high. Include 10% waste. Concrete must be ordered in 1/4-cubic-yard increments.

7) The site shown in Figure 2 requires 4 inches of topsoil. The bark is two inches thick. Determine the topsoil, bark, and landscaping plants required to complete the planter.

8) *Excel Quick Tip 17-1: Asphalt or Base*

Calculate the number of tons of asphalt needed for a 10,000 square foot parking lot if the asphalt is 5 inches thick and has a density of 155 pounds per cubic foot.

Figure 1: Sewer Line Plan and Profile

Figure 2: Sewer Line Cross Section

9) A 20-inch-wide by 3-foot-deep trench is dug in the ground and a water line with a 4.75 inch outside diameter is placed in the trench. The water line is placed on 5 inches of bedding, and bedding surrounds the pipe to a height of 2.25 inches above the water line. The length of the trench is 800 feet. Determine the volume of excavation needed for the water line.

10) A 20-inch-wide by 3-foot-deep trench is dug in the ground and a water line with a 4.75 inch outside diameter is placed in the trench. The water line is placed on 5 inches of bedding, and bedding surrounds the pipe to a height of 2.25 inches above the water line. The length of the trench is 800 feet. How much bedding is needed?

11) A 20-inch-wide by 3-foot-deep trench is dug in the ground and a water line with a 4.75 inch outside diameter is placed in the trench. The water line is placed on 5 inches of bedding, and bedding surrounds the pipe to a height of 2.25 inches above the water line. The length of the trench is 800 feet. The water line is constructed of 20-foot-long pipes with a bell and gasket on one end. How many pieces of pipe are needed?

12) A 20-inch-wide by 3-foot-deep trench is dug in the ground and a water line with a 4.75 inch outside diameter is placed in the trench. The water line is placed on 5 inches of bedding, and bedding surrounds the pipe to a height of 2.25 inches above the water line. The length of the trench is 800 feet. How much backfill is needed for the water line?

13) A utility contractor is to install the sewer line whose plan and profile are shown in Figure 1. The trench is to have the cross section shown in Figure 2. Using the average-end method, determine the volume of excavation in cubic yards needed to install the sewer line. The excavation for the manhole is to be 6 feet by 6 feet and two feet deeper than the flow line at the manhole.

14) A utility contractor is to install the sewer line whose plan and profile are shown in Figure 1. The trench is to have the cross section shown in Figure 2. Using Eq. (18-1), determine the volume of excavation in cubic yards needed to install the sewer line. The excavation for the manhole is to be 6 feet by 6 feet and two feet deeper than the flow line at the manhole.

15) A utility contractor is to install the sewer line whose plan and profile are shown in Figure 1. The trench is to have the cross section shown in Figure 2. The pipe is bedded in gravel. The depth of the gravel is 1 foot and the pipe is bedded into the gravel 4 inches. The outside diameter of the sewer pipe is 9 inches. Ignoring the manhole, determine the quantity of gravel needed for the sewer line.

16) A utility contractor is to install the sewer line whose plan and profile are shown in Figure 1. The trench is to have the cross section shown in Figure 2. The pipe is surrounded by gravel. The depth of the gravel is 20 inches. The outside diameter of the sewer pipe is 9 inches. Twelve inches of bedding is also placed below the manhole. Determine the quantity of gravel needed for the sewer line.

17) Determine the utility components needed for the sewer line in Figure 1. The pipe is available in 20-foot lengths and includes a bell with a gasket at one end.

18) A utility contractor is to install the sewer line whose plan and profile are shown in Figure 1. The trench is to have the cross section shown in Figure 2. The excavation for the manhole is to be 6 feet by 6 feet and two feet deeper than the flow line at the manhole. The pipe is surrounded by gravel bedding. The depth of the gravel is 20 inches. Determine the volume of backfill for the sewer line. The manhole has an outside diameter of 4 feet and its bottom is one foot below the flow line.

19) *Excel Quick Tip 18-1: Trench Excavation Using Average-end Method*
