Which component sits directly on the foundation wall and provides bearing for floor joists?

• A. Sills
• B. Piers
• C. Footings
• D. Pocket

Answer: (A)

The sill (sill plate) is the piece that sits directly on the foundation wall and provides the bearing surface for the floor joists. It forms the bottom edge of the wall framing, is typically treated lumber, and is anchored to the foundation with bolts so the wall stays secure and the joists have a solid, level surface to bear on. The floor joists end on the sill and are nailed to it, creating the crucial transfer of load from the floor into the foundation. Piers and footings are part of how loads are carried into the soil below, not the immediate bearing surface for the joists, and pockets are features used in other contexts, not for supporting floor joists.
