Concrete Spread footing projections shall be at least _____ and shall not exceed the thickness of the footings.

The requirement for concrete spread footing projections to be at least 2 inches is based on maintaining structural integrity and providing adequate support. A minimum projection helps distribute load effectively and prevents potential sideways movement or slippage of the footing. If the projection is too small, it may not provide sufficient bearing surface, leading to inadequate support and potential structural issues.

Setting a maximum limit on the thickness of the footings ensures that the footing is constructed with strength while preventing excessive material use, which can lead to unnecessary costs and complicate the construction process. Keeping the projection within these defined parameters promotes both efficiency and safety in construction practices.
