Using a waste factor of 7 percent, determine the number of cubic yards of concrete needed to pour the continuous footings shown in Figures 11.36 and 11.37. Assume that the wall is centered over the footing.

The image is a foundation plan for a building, labeled as "FIGURE 11.36. Foundation Plan." ### Description: - The foundation layout consists of angular structures with dimensions given in feet. - The overall layout forms an L-shape when viewed from above. ### Dimensions and Layout: - The width of the longer section of the foundation is 36 feet. - The depth along the left vertical side measures 25 feet. - The right vertical section of the plan is 20 feet high. - The top horizontal section extends 21 feet above the indentation. ### Indentation Details: - There is a stepped indentation on the top right, measuring 5 feet vertically and 15 feet horizontally. ### Additional Features: - Two small square structures are indicated in the top right, outlined with dashed lines, suggesting auxiliary features or installations. - The diagram uses solid and dashed lines to outline the various aspects of the foundation, with dashed lines often indicating hidden or underlying elements. This foundational plan is essential for understanding the structural base dimensions of a building project, critical for ensuring accurate construction and stability.

**Foundation Section Diagram: Figure 11.37** This diagram illustrates a detailed section of a foundation setup with various construction specifications: - **2 x 4 Wall with 7/16" OSB**: Indicates a wall made from 2 x 4 studs covered with 7/16 inch Oriented Strand Board (OSB). - **5/8" x 10" Anchor Bolt @ 32" O.C.**: Anchor bolts that are 5/8 inch in diameter and 10 inches long, spaced 32 inches on center. - **8"**: Measurement, possibly indicating the spacing from the wall to another component. - **#4 Rebar @ 12" O.C. Bothways**: Reinforcement bars (#4 rebar) spaced 12 inches on center in both horizontal directions. - **#5 Dowels @ 12" O.C. Alternating Directions**: Dowels (#5) spaced at 12 inches on center, alternating in directional placement for structural stability. - **2 Each #4 Rebar Top and Bottom**: Two #4 rebars placed at both the top and bottom sections of the foundation. - **4 Each #4 Cont. Rebar**: Four continuous #4 rebars integrated within the structure for reinforcement. - **Foundation Dimensions**: The diagram specifies a height of 10 feet overall for the wall structure and a foundation block of 1 foot height and 2 feet 6 inches width, with a specific mention of 1 foot 3 inches from a certain section to the top of the foundation block. This diagram provides detailed measurements and guidelines for constructing a robust foundational structure using specified materials and reinforcement techniques.
