When preparing a job site for excavation or construction, the removal of objects below the original ground is called ________.

• A. Grubbing
• B. Grading
• C. Backfilling
• D. Dewatering

Answer: (A)

Clearing vegetation and organic material from a site so you can dig and lay the foundation is grubbing. This involves removing stumps, roots, brush, and other stuff beneath the surface to expose solid ground and prevent roots or debris from interfering with excavation and the subgrade. Grading, by contrast, is about shaping and leveling the surface after digging. Backfilling is filling in an excavated area later, and dewatering is pumping out water to keep the area dry. So grubbing is the right term for removing objects below the original ground to prepare the site.
