What shows the location of wall reinforcement, such as anchor bolts?

The foundation plan is the correct choice because it specifically details the structural elements of a building's foundation, including the location of wall reinforcement features such as anchor bolts. This plan focuses on aspects that support the building’s weight and provide stability, indicating how the walls will be anchored to the foundation to ensure structural integrity.

In contrast, the elevation plan is used to represent the vertical aspects of a building, showcasing how the structure will appear from different perspectives, but it does not provide detailed information about the foundation and wall reinforcement. The site plan offers an overall view of the property layout, including structures, landscaping, and site features, but it is not focused on the specifics of foundation reinforcement. A floor plan illustrates the arrangement of rooms and spaces within the building; while it indicates initial wall placements, it is not intended to convey structural details like the placement of anchor bolts. Thus, the foundation plan is the most accurate representation of where wall reinforcement elements are located.
