What is the required extension of masonry footings beyond the foundation wall on all sides?

• A. 4 inches
• B. 5 inches
• C. 6 inches
• D. 7 inches

Answer: (C)

The requirement for masonry footings to extend beyond the foundation wall on all sides by 6 inches is crucial for several structural engineering reasons. This extension helps distribute the load of the wall more effectively across the footing, ensuring stability and preventing settling or shifting. A 6-inch extension allows for adequate support of the structure and aids in drainage, reducing the risk of water pooling near the foundation. It also contributes to the overall durability of the building, preventing issues such as cracking and moisture infiltration that can arise when footings are too narrow. This extension is a standard guideline in construction practices, ensuring that footings adequately support the walls and the overall structure.
