Excavator — Stockpiled Material

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.

Excavator to Grading Workflow

An excavator can open ground, remove unsuitable material and work below surrounding level. The grading handover begins when accessible material and formation are ready for controlled redistribution.

Before moving material

Agree excavation limits and the formation reference.

Receiving operation and checks

Compact, survey or place the next layer as specified. Check trench edges, disturbed areas and remaining excavation defects.

A scraper is not a substitute for an excavator's digging or lifting functions.

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.
