Poor Discharge — Machine-After Issue

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.

Poor Surface Drainage

Poor surface drainage can result from a blocked outlet, a reversed fall, a damaged crossing or local depressions. Grading should follow the identified cause.

Before moving material

Trace water from its entry point to the receiving outlet.

Receiving operation and checks

Inspect the drainage route during a suitable water event. Check that the complete route remains connected through boundaries and crossings.

Surface grading cannot remedy every subsurface drainage problem.

Poor Irrigation Surface

An irrigation surface can be poor because of inlet mismatch, local depressions or altered field grade. The correction should follow water observations and measured levels.

Before moving material

Record water movement and survey supply, outlet and field features.

Receiving operation and checks

Recheck levels and observe the next controlled irrigation. Check corners, row ends and the far end of the field.

Grading alone cannot correct an unsuitable water-delivery arrangement.

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.
