Survey Crew — Truck-Dumped Fill

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.

Cut-and-Fill Mapping

Cut-and-fill mapping shows differences between existing and target surfaces. Its colours are useful only when the surfaces share compatible references and the legend's sign convention is understood.

Before moving material

Check survey and design datum, extent and revision.

Receiving operation and checks

Use the map to plan movement and remeasure progress. Check sample locations and distinguish geometric volumes from usable material quantities.

Do not equate map balance with a guaranteed material balance after compaction.

Truck to Material Placement & Grading

Truck delivery is a material-supply event, not a surface acceptance event. Placement planning prevents large piles from blocking access or exceeding the available layer depth.

Before moving material

Confirm delivery material and safe discharge locations.

Receiving operation and checks

Shape and compact the layer before accepting the next delivery stage. Check receiving levels and reconcile delivered quantities with the volume state used.

A delivered loose volume is not a verified compacted volume.

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.
