Bulk Scraper → Dugong → Precision Grade: Surface Required By Next Operation

Bulk Scraper to Fine Grading

Bulk scrapers serve major material movement; fine grading serves the smaller deviations left near the target surface. Select the changeover by remaining quantity and finish requirements.

Before moving material

Survey after bulk placement and identify accepted and unaccepted zones.

Receiving operation and checks

Prepare for compaction or the next layer. Check residual high points and depressions between bulk runs.

A smaller scraper is not automatically faster; compare the remaining task and route.

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.

Prepare for the Next Operation

Preparing for the next operation means identifying what the receiving team needs to start without rework. The handover may need access, layer condition, levels and records.

Before moving material

Ask the next operator or contractor for the required surface condition.

Receiving operation and checks

Hand over the checked area with outstanding items stated. Verify the agreed interface rather than only the grading team's own completion point.

Do not transfer unresolved defects silently to the next trade.

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.
