What is the primary purpose of foundation drawings?

The primary purpose of foundation drawings is to depict the layout and design of a building's foundation. These drawings provide essential details regarding the dimensions, materials, and specifications required for the foundation, which is a critical aspect of the building's structural integrity. They guide construction efforts by ensuring that the foundation is built according to the intended design, supporting the overall stability and safety of the building. Foundation drawings often include information about footings, depth, and type of foundation, which are crucial for understanding how the building will interact with the soil and withstand various loads.
