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

The foundation plan is the correct answer because it specifically illustrates the details related to the foundation of a structure, including the placement of foundational elements like anchor bolts, wall reinforcement, and other supporting features. This plan serves as a critical guide for the building process, ensuring that all structural reinforcements are correctly located to maintain the integrity and stability of the building.

In a foundation plan, contractors can identify how and where to install various support systems necessary for the walls above. This often includes details on the size and spacing of anchor bolts, which are essential for securing walls to the foundation and preventing movement caused by environmental factors or structural loads.

In contrast, other plans such as the site plan, roof plan, and floor plan serve distinct purposes. The site plan provides an overview of the entire property layout and the positioning of the building relative to property lines and other site features. The roof plan focuses on the design, structure, and drainage of the roof system, while the floor plan depicts the arrangement of rooms and walls within each level of the building. None of these documents specifically highlight the foundation details in the same way the foundation plan does.
