Laser Land Grading

Laser land grading references elevation to a transmitter-defined plane or gradient arrangement. It can be useful where the required surface fits that reference, provided setup and receiver geometry are controlled.

Before moving material

Confirm the target surface and transmitter/receiver compatibility.

Receiving operation and checks

Check finished levels independently of the receiver display. Watch for reference movement, blocked reception and incorrect offsets.

No accuracy figure is promised without the specified system and working conditions.

GPS Land Grading

GPS-based grading uses positioning information in relation to a design or reference surface. Ordinary navigation positioning should not be treated as a precision earthworks control system.

Before moving material

Identify the positioning equipment, corrections and design requirements.

Receiving operation and checks

Verify the achieved surface separately. Record correction status and any loss of usable positioning during work.

A satellite receiver alone does not establish vertical grading accuracy.

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.
