What is typically not a function of foundation drawings?

Foundation drawings are primarily concerned with the structural elements that support the building. Their main functions include indicating load-bearing walls, illustrating how the foundation interacts with the structure above, and displaying the design of the base structure, including dimensions and material specifications.

Detailing the electrical layout of a building falls outside the scope of foundation drawings. Electrical layouts are usually included in separate sets of drawings dedicated to electrical engineering, which outline the placement of wiring, outlets, fixtures, and other electrical components. By focusing on the structural integrity and foundation of a building, foundation drawings provide essential information necessary for the groundwork, while electrical considerations are addressed in their own documentation. This distinction makes the electrical layout not a function of foundation drawings.
