The minimum point is where which transition occurs?

The minimum point is where which transition occurs?

• A. The cut transitions into fill
• B. The zero balance line
• C. The fill transitions into cut
• D. Waste region

Answer: (C)

In earthwork planning, you compare the existing ground with the proposed grade along the alignment. Where the proposed grade sits above the existing ground, you need fill; where it sits below, you need cut. The point where the two surfaces intersect is where the required work changes sign—from adding material to removing material. That intersection corresponds to the minimum point of the profile, so you transition from fill to cut there. The other terms (like the zero balance line or waste region) refer to different aspects of balancing volumes or handling spoil, not the location of this transition.
