What is depicted in a foundation plan?

A foundation plan provides a detailed view of the structure's foundation layout, showcasing the footprint of the building as seen from above. This includes the dimensions, locations of footings, walls, and any load-bearing elements that will support the building above. By presenting a plane view, the foundation plan allows engineers and contractors to understand precisely where the foundation will be placed, ensuring proper alignment with the architectural design and structural integrity.

The other options, such as furniture layout, external building height, and overall project site layout, serve different purposes in the design and construction process. Furniture layout focuses on the interior space planning within a building, while external building height pertains to the vertical measurements of the structure itself. The overall project site layout encompasses a broader view of the entire site, including landscaping and utilities, rather than the specific details of the foundation.
