Which of the following is not typically shown on a foundation plan?

1. Height of foundation walls

2. Size of footings

3. Location of utility lines

4. Depth of excavation

The correct answer is: Height of foundation walls

The height of foundation walls is not typically shown on a foundation plan because this type of plan primarily focuses on the layout and dimensions of the foundation itself, including the footprint of the structure, the size of footings, and any critical structural notes related to the foundation's design. Foundation plans detail the horizontal aspects of foundation construction, such as the layout of the footings and the configuration of the walls, and they provide necessary information to facilitate the excavation process. Since the height of the foundation wall is more relevant to elevation or framing plans, rather than foundational layout, it is generally not included in the foundation plan. In contrast, the size of footings, location of utility lines, and depth of excavation are all critical components of the foundation plan, as they directly relate to ensuring the foundational integrity and proper function of the building. Footing sizes are essential for load distribution, utility line placement is important for ensuring that systems like plumbing and electrical are integrated correctly into the structure, and excavation depth is crucial for setting the foundation at the correct level.
