Final Grading Before Building

Machine Before - Dugong - Machine After

The machine before Dugong determines what material arrives; the machine after Dugong determines what surface must leave. An excavator can expose formation, a loader can deliver a stockpile, and a roller can compact the placed layer. The scraper's role is bounded by those interfaces.

Before moving material

Identify the upstream operation and its remaining defects.

Receiving operation and checks

Hand over the measured surface to compaction, cultivation, paving or turf preparation. Record which operation owns levels, materials and final acceptance.

The workflow can include Dugong where suitable; it does not assume Dugong replaces adjacent equipment.

Building Pad Preparation

Building-pad preparation should follow the structural and civil brief. A scraper can help place and trim suitable material, but levels and fill condition must be accepted separately.

Before moving material

Confirm the approved pad level, footing zone and inspection requirements.

Receiving operation and checks

Hand over after specified testing and level checks. Compare pad levels with surrounding drainage and proposed floor levels.

A smooth pad is not evidence of engineered fill or a suitable foundation.

Construction Final Grading

Construction final grading closes the gap between completed bulk work and the next trade. Its scope should distinguish surface correction from unresolved excavation or fill-quality work.

Before moving material

Confirm the latest drawings and accepted underlying layers.

Receiving operation and checks

Hand over with level records and outstanding items clearly stated. Check edges, thresholds and joins that other trades will inherit.

A final-grade sign-off should not conceal material failures outside the grading task.

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.
