Base Station — Verification
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.
Precision Grade Control
Precision grade control is the stage where a reference system is commissioned for the intended surface. It needs design transfer and equipment checks before productive grading.
Before moving material
Confirm design revision, datum and the working-edge reference.
Receiving operation and checks
Verify surface results independently during and after the work. Record calibration and any reference interruptions.
Machine guidance is not acceptance certification.

Before road base is placed, the subgrade should be accepted for both level and condition. An uneven or weak supporting surface can lead to thickness variation and premature failure above it.
Before moving material
Confirm formation level and identify unaccepted areas.
Receiving operation and checks
Inspect and accept before spreading base aggregate. Record level and material checks for the same work area.
Adding more base material is not automatically a remedy for weak subgrade.

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.

Use this checklist to turn the scenario into a specific brief. Retain the design revision and agree who accepts each completed layer.
Checklist ticks apply only while this page is open. Include the completed brief in your project records.
