What is the minimum depth required for removing stumps and roots prior to construction?

  1. 8"

  2. 10"

  3. 12"

  4. 14"

The correct answer is: 12"

The minimum depth required for removing stumps and roots prior to construction is set at 12 inches. This guideline is crucial to prevent any potential issues with the foundation and structural integrity of the building. When stumps and roots are left in place, they can decompose over time, which may cause settling or shifting of the ground above and ultimately lead to structural problems such as cracks in walls, uneven floors, or failure of the foundation. By ensuring that stumps and roots are removed to a depth of at least 12 inches, it allows for a more stable and uniform soil condition that is vital for supporting the loads of the building. This practice also helps to eliminate any potential for pest infestations or the growth of vegetation that could interfere with the construction process. Understanding this requirement ensures that future construction projects adhere to best practices for site preparation, ultimately leading to safer and more durable structures.
