Uneven Subgrade — Dugong Cut Carry Grade for Rehabilitation
Define the finished purpose, reference levels, underlying material condition and the evidence required by the receiving operation. Geometry alone does not establish structural or agronomic performance.
This reference assembles relevant extracts from the guide library. It is general project planning, not a local project report, verified specification or translated technical publication.
Cut, Collect, Carry, Place & Grade
Cutting, collecting, carrying, placing and grading are different tasks. A machine that drags material forward does not necessarily carry a contained load to a distant low area. Break the earthworks into these actions so the route, implement and checking method match the actual work.
Before moving material
Survey high areas, receiving areas and obstacles before loading.
Receiving operation and checks
Recheck levels before another layer or another operation covers the work. Track the destination of material as well as the appearance of the cut.
Material suitability, safe towing and compaction requirements remain separate decisions.

Dugong's cut, collect, carry, place and grade sequence should be planned around the job's actual material route. Filling a bowl is not the end of the task; placing material correctly and checking the surface are part of the cycle.
Before moving material
Mark source and receiving areas and confirm tractor suitability.
Receiving operation and checks
Prepare and verify the receiving layer. Include empty return and turning time when estimating the cycle.
The workflow does not promise a universal hourly production rate.

Uneven subgrade can create variable thickness in every layer above it. Correcting the surface is useful only if the underlying support is acceptable.
Before moving material
Identify soft areas and compare formation levels with design.
Receiving operation and checks
Complete compaction and specified acceptance checks. Check levels before base material conceals the subgrade.
A scraper does not replace proof testing or project-specific investigation.
