For a one-story dwelling with a uniform wall load of 1100 plf, what is the minimum depth of crushed stone footing?

To determine the minimum depth of crushed stone footing for a one-story dwelling with a specific wall load of 1100 pounds per linear foot (plf), various building codes and engineering principles dictate the standards for footings. The load on the footing is a crucial factor because it influences how well the footing will distribute the load across the soil beneath it.

In this scenario, the standard practice would typically involve assessing soil bearing capacity, the load being imposed, and then applying safety factors to ensure stability and safety.

The specified depth of 6 inches for the crushed stone footing is correct based on established engineering practices. This depth helps ensure adequate load distribution and minimizes settling. Crushed stone is often used because it provides good drainage and can withstand varying load conditions while maintaining stability.

Choosing a depth of 6 inches aligns with common requirements found in local building codes for residential construction, where the depth must accommodate the specific load calculations, soil conditions, and overall design safety. This depth also helps prevent issues like frost heave and ensures that the footing remains stable under normal use conditions over time.

Overall, 6 inches is a practical and commonly accepted minimum depth in residential construction projects when considering the uniform wall load specified in the question.
