What does grubbing involve in construction work?

1. Filling holes in the ground

2. Removing stumps, roots, and stubs

3. Cutting back trees

4. Leveling the land

The correct answer is: Removing stumps, roots, and stubs

Grubbing in construction work specifically refers to the process of removing stumps, roots, and other organic debris from the site. This is a critical step in preparing a construction area, especially for projects involving earthwork, foundation preparation, or road building. By clearing out these elements, grubbing helps to ensure that the soil can be properly compacted and that the structural integrity of the construction is not compromised by decaying organic materials which can lead to settling over time. Removing stumps and roots not only improves the aesthetic and functional aspects of the site but also prevents complications during later stages of construction, such as damage to machinery or interference with drainage systems. It is an essential part of land clearing to create a stable and level base for any construction activities.
