What is the structural base of a building?

• A. Slab
• B. Footings
• C. Foundation
• D. Pier

Answer: (B)

The structural base is what transfers a building’s loads into the ground. Footings do this by spreading the weight from columns or walls over a larger area, which reduces soil pressure and helps prevent differential settlement. They sit below ground level and are a fundamental part of the foundation system, often reinforced for strength.

A slab is a floor or decking element, not the base that distributes load to the soil. A pier is a vertical support that carries loads downward but relies on footings or another foundation element to transfer those loads to the ground. A foundation covers the broader system, but the specific component that actually spreads and transfers the load into the soil is the footing.
