What may occur if soil is excavated only to the bottom of a footing when lowering a basement floor?

Increased moisture levels
Loss of lateral support for the footing
Soil erosion around the foundation
Higher construction costs

The correct answer is: Loss of lateral support for the footing

Excavating only to the bottom of a footing when lowering a basement floor can result in a loss of lateral support for the footing. Footings are designed to distribute the weight of the structure above to the soil below. When the surrounding soil is removed to the level of the footing without adequate consideration for lateral stability, the soil that once provided support is eliminated. This reduction in support can compromise the integrity of the foundation, leading to potential settlement, shifting, or even failure of the footing. Understanding the significance of lateral support is crucial for maintaining the structural integrity of a building, particularly during renovations that involve deep excavations. Compromising this support can lead to severe structural issues, which can be much more costly and complex to address later on. While it's important to note that increasing moisture levels, soil erosion, and construction costs can all be relevant concerns in various construction scenarios, the most immediate and critical risk when excavating only to the bottom of a footing is the potential loss of lateral support. This makes it essential to plan excavations carefully to ensure the stability of the entire foundation system.
