Massachusetts Unrestricted Construction Supervisor License Practice Test

A foundation that has a finished grade that slopes away from the building must be a minimum of ____ inches lower at a point ____ feet away from the face of the wall?

1. 4, 6

2. 6, 10

3. 8, 12

4. 10, 15

The correct answer is: 6, 10

The correct answer is based on the established guidelines concerning the drainage and grading necessary for effective water management around a building's foundation. When the finished grade slopes away from the foundation, it is crucial to maintain a specific elevation difference to ensure that water moves away from the structure, helping to prevent water pooling and potential damage to the foundation. The requirement that the foundation must be a minimum of 6 inches lower at a point 10 feet away from the face of the wall is aligned with best practices in construction and drainage management. This guideline ensures that the slope is adequate to facilitate effective drainage, thereby reducing the risk of water infiltration and other related issues that could compromise the structural integrity of the building over time. In terms of the other options, while they may suggest different measurements and distances, each fails to adhere to the recommended standards that dictate the necessary slope for effective drainage. Thus, option B is the most accurate response reflecting the approved practices for building site drainage.
