How is a design cut/fill line used in earthmoving planning?

• A. To identify options for widening roads.
• B. To determine the sequence of earthworks.
• C. To identify finished elevations and where earth must be cut or filled to meet the design.
• D. To select machinery brands.

Answer: (C)

The design cut/fill line represents the finished ground surface the project must achieve and where earth must be removed or added to reach that surface. In earthmoving planning, this line is produced from the design and then marked on the site so you can see exactly where material needs to be cut away and where fill is required. By comparing the existing ground to this line, you can determine cut and fill quantities, guide grading to the correct elevations, and plan how to balance earthwork before moving equipment. This is why it’s the best choice: it directly identifies the finished elevations and where earth must be cut or filled to meet the design. Widening roads, sequencing earthworks, or selecting machinery brands aren’t determined by the cut/fill line.
