Water Authority — Precision Grading Specification (14600)
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.
Water Ponding
Ponding is a symptom, not a design instruction. Filling the wet patch can push water into another area if the outlet or surrounding grade remains wrong.
Before moving material
Record pond extent, duration and outlet condition.
Receiving operation and checks
Correct the confirmed issue and observe the result after suitable rainfall or irrigation. Check water movement beyond the repaired patch.
Persistent wetness may require soil or drainage investigation beyond grading.

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.

A government or council project brief should separate asset requirements from the choice of grading plant. Specify the surface outcome and acceptance evidence before inviting machinery-based solutions.
Before moving material
Identify the asset, stakeholders and required design inputs.
Receiving operation and checks
Review the proposed method against the brief and retain acceptance records. Check that design, grading, testing and handover responsibilities are assigned.
No government endorsement or supplier-panel membership is implied.

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.
