Gnss Grading — Operator Checklist

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.

Operator Preparation and Site Responsibilities

Operator preparation should match the supplied machine, tractor combination and worksite. General familiarity with a tractor is not proof that an operator understands scraper loading, release or transport arrangements.

Before moving material

Obtain machine instructions and the employer's applicable training requirements.

Receiving operation and checks

Keep operating and maintenance arrangements consistent with the supplied configuration. Confirm that the operator can explain the controls and limits used on the job.

Training and workplace duties depend on the jurisdiction and task; this is not legal certification.

Precision Landforming

Precision landforming follows a designed surface rather than repeatedly smoothing whatever the operator sees. Its value lies in controlling where material is removed and placed relative to that surface.

Before moving material

Establish reliable survey control and a suitable design model.

Receiving operation and checks

Record the achieved surface before cultivation, compaction or construction. Check joins and breaklines where changes in slope are intentional.

Guidance accuracy alone does not prove the material or finished surface is suitable.

Record the job inputs

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

• Existing condition, extent and the reason for intervention
• Required finished purpose, receiving operation and acceptance criteria
• Material type, layer role, source, receiving area and volume state
• Reference levels, datum, survey method and issued design revision
• Available tractor, implement configuration, travel route and turning space
• Checks before work, stopping points and evidence retained at handover

Checklist ticks apply only while this page is open. Include the completed brief in your project records.
