Gps Compatibility — What Is Not Guaranteed for Civil
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.
What Verification Evidence Proves
Verification evidence should answer the acceptance question asked. Elevation measurements establish geometry; material records and relevant tests address layer condition. Neither should be silently substituted for the other.
Before moving material
Define the checks needed for the finished purpose.
Receiving operation and checks
Hand over accepted areas and clearly identify exceptions. Check that the evidence concerns the same layer and work zone.
An instrument display is not a complete acceptance record.

Civil construction grading sits within a design, material and inspection sequence. The useful question is which layer is being handed to which contractor, not whether the site merely looks level.
Before moving material
Confirm approved drawings, services and inspection hold points.
Receiving operation and checks
Verify the completed layer before the next trade covers it. Record levels, material records and unresolved defects together.
Dugong may suit controlled redistribution; deep excavation and engineered fill acceptance need their own methods.

GPS-based grading uses positioning information in relation to a design or reference surface. Ordinary navigation positioning should not be treated as a precision earthworks control system.
Before moving material
Identify the positioning equipment, corrections and design requirements.
Receiving operation and checks
Verify the achieved surface separately. Record correction status and any loss of usable positioning during work.
A satellite receiver alone does not establish vertical grading accuracy.

Use this checklist to turn the scenario into a specific brief. Retain the design revision and agree who accepts each completed layer.
