Survey, Design & Verification
Finished-Surface Survey
A finished-surface survey records the result after grading. It should be compared with the same design revision and reference used for construction.
Plan the surface handover
BeforeAgree the acceptance locations and datum before surveying.
Work stageMeasure the completed surface and compare actual elevations with target elevations, including edges and transitions.
AfterDocument accepted areas and defects needing correction.
What to verify
Keep the survey evidence separate from the machine's production display.
Keep the design reference and survey evidence traceable. State units, coordinate system, vertical datum and revision, then compare independent checks with the issued target. Surface measurements establish geometry; they do not establish the material quality of a buried layer.
Scope and limits
A level survey does not establish compaction or material quality.
