Question

Determine the number of linear feet of forms needed for the continuous footings shown in Figures 11.36 and 11.37.

**Figure 11.36: Foundation Plan**

The diagram illustrates a foundation plan with specific dimensions and layout details for construction purposes. The plan outlines a stepped rectangular shape with measurements annotated for various segments.

- The longest horizontal dimension at the base measures **36 feet**.
- The vertical dimension on the left side is **25 feet**.
- The top horizontal segment is divided into **21 feet** and a **15 feet** section, split by a step in the design.
- The vertical segment on the right side is **20 feet**.
- The stepped inset on the top right includes a **5 feet** horizontal section that leads to a perpendicular segment.
- Two dashed-line squares to the top right of the plan indicate potential additional structural features or posts.

Dashed lines within the external perimeter likely represent internal structural or foundational elements such as footing or reinforcement zones. The layout may be part of a larger design, indicating the foundational blueprint for a building’s structure.

### Figure 11.37: Foundation Section

#### Description:

This diagram represents a vertical section of a foundation, detailing the reinforcement and construction specifications for a wall structure.

#### Elements and Specifications:

- **Wall Structure**: 
  - *2 x 4 Wall with 7/16" OSB*: This indicates a wooden frame wall constructed with two-by-four studs and a 7/16 inch oriented strand board (OSB) sheathing.

- **Anchor Bolt**: 
  - *5/8" x 10" Anchor Bolt @ 32" O.C.*: These bolts are spaced 32 inches on center (O.C.) and used to secure the wall frame to the foundation.

- **Reinforcement Details**: 
  - *#4 Rebar @ 12" O.C. Bothways*: Number 4 rebar is placed 12 inches on center in both horizontal and vertical directions within the foundation for reinforcement.
  - *#5 Dowels @ 12" O.C. Alternating Directions*: Number 5 dowels are spaced 12 inches on center and placed in alternating directions to provide additional reinforcement.
  - *2 Each #4 Rebar Top and Bottom*: Two pieces of number 4 rebar are positioned at both the top and bottom of the foundation section.
  - *4 Each #4 Cont. Rebar*: Four continuous pieces of number 4 rebar span the length of the foundation, providing stability and support.

#### Dimensions:

- **Foundation Depth**: 10 feet overall height from the bottom of the foundation to the top of the wall section.
- **Wall Section**: Extends 1 foot, 3 inches above the foundation.
- **Foundation Block**: 
  - Height: 1 foot
  - Width: 2 feet, 6 inches

This diagram illustrates how to integrate various construction materials and techniques to ensure structural integrity in the foundation of a building, emphasizing the positioning and type of reinforcements used.
