Temporary Works Surface — Machine Handover

The Surface Is the Handover

The surface is the handover between operations. An excavator may finish its excavation, but the roller still needs suitable material, lift thickness and moisture. A scraper may finish shaping, but the irrigation operator still needs a connected fall to a usable outlet. Define acceptance at each transition instead of allowing the next machine to inherit an unresolved problem.

Before moving material

Name the operation that receives the surface and agree its requirements.

Receiving operation and checks

Release the area to the next operation only after outstanding defects are identified. Use independent level checks and project-specific material tests where required.

Visual smoothness alone does not prove compaction, bearing capacity or hydraulic performance.

Weight That Works

Working weight influences cutting, traction and ground loading, but weight alone does not establish grading performance. Ballast, a carried load and attachment weight also change the demands on the tractor, hitch and tyres. Consider the complete combination in both loaded and empty states.

Before moving material

Obtain the machine weights, hitch limits and tractor information.

Receiving operation and checks

Use a controlled trial to establish a workable pass depth. Observe slipping, rutting and unstable handling before chasing greater load.

More weight may damage soft ground and does not make a machine suitable for every tractor.

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.

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.
