Excavator → Dugong → Padfoot Compactor: Grade Control

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.

Excavator vs Grader Scraper

An excavator is useful for digging below surrounding grade and working in confined locations; a grader scraper can move workable surface material between accessible cut and fill areas. Compare their roles across the whole job.

Before moving material

Identify excavation depth, material source and receiving distance.

Receiving operation and checks

Survey and prepare the placed material. Compare complete workflows, including loading and final trimming.

Neither machine category is a universal replacement for the other.

GNSS Machine Control

GNSS machine control combines positioning, machine geometry and design information. An accurate receiver position is not automatically an accurate cutting-edge position.

Before moving material

Confirm corrections, sensor arrangement and the coordinate reference.

Receiving operation and checks

Check the completed surface with an independent method. Inspect offsets, design revision and correction status when results disagree.

Compatibility must be confirmed for the actual machine and control installation.

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.
