What is the primary purpose of grading in the construction process?

The primary purpose of grading in the construction process is to establish a level surface and control water drainage. Grading involves the manipulation of the earth's surface to create a desired topography that allows for effective water management. Proper grading ensures that water drains away from structures, preventing potential water damage and erosion. It is also crucial for ensuring that a surface is adequately prepared for subsequent construction activities, such as laying foundations or paving.

While determining material strength and durability is essential in construction, it is not the direct purpose of grading. Similarly, calculating project costs pertains to budgeting and financial planning rather than the grading itself, and inspecting materials involves quality control, which occurs after the grading process. All of these aspects are important in construction, but they serve different functions than the primary objective of grading.
