What are the two types of grading mentioned?

Rough grading and fine grading are two critical phases in the grading process that help shape the land for various construction projects. Rough grading involves the initial and major excavation and movement of earth. It establishes a general contour and prepares the site for the finer details that come in later stages. This stage can include the removal of large rocks, debris, and vegetation, as well as leveling out large areas.

Fine grading, on the other hand, is the detailed work that follows rough grading. During this phase, the surface of the ground is carefully smoothed and refined to a precise grade. This is essential for preparing the site for laying foundations, finished surfaces, or landscaping. Proper fine grading ensures adequate drainage and prevents future issues related to settling or uneven surfaces.

Other options, such as surface grading and deep grading, do not capture the distinct processes involved as accurately as rough and fine grading. Likewise, land grading and soil grading refer to broader concepts that don’t specify the operational phases. Coarse grading and fine grading also do not accurately represent the terminology used within grading practices. Therefore, the distinction between rough grading and fine grading is crucial for understanding how sites are prepared in construction and landscaping.
