40 Hour Property and Building Inspection Practice Test

In platform construction, how do walls relate to the subfloor?

1. They are supported by the roof

2. They sit on the subfloor

3. They are suspended above the subfloor

4. They are built before the subfloor

The correct answer is: They sit on the subfloor

In platform construction, walls sit directly on the subfloor, which is a fundamental aspect of this building method. This means that the vertical structural elements, such as the walls, rely on the strength and stability of the subfloor to provide support and ensure proper alignment. By resting upon the subfloor, the walls help distribute loads and transfer weight down to the foundation, contributing to the overall structural integrity of the building. The relationship between the walls and the subfloor is crucial in providing a stable platform for subsequent framing, including the construction of upper levels or roofs. This method of construction allows for easier installation of walls and contributes to the efficiency and effectiveness of the overall building process. The other options do not accurately capture this direct support relationship, making the choice that states the walls sit on the subfloor the correct one.
