How is the design cut/fill line used to plan earthwork?

• A. To estimate total project duration.
• B. To locate underground utilities.
• C. To identify finished elevations and where earth must be cut or filled to meet the design.
• D. To determine personal protective equipment required.

Answer: (C)

The design cut/fill line shows the finished surface elevations you must achieve. By comparing this line to the existing ground, you can see exactly where the earth must be cut (removed) and where it must be filled (added) to meet the design. This is what guides how much earthwork is needed in each area, helps you calculate cut and fill quantities, and informs the sequencing, equipment needs, and material balance for the project. It isn’t used to estimate project duration, locate underground utilities, or determine PPE—those come from other plans and site assessments. The cut/fill line focuses on finishing elevations and how much earth must move to reach them.
