Dozer — Subgrade Preparation

Subgrade Preparation

Subgrade preparation creates the surface that supports the next pavement or structural layer. The visible level and the condition of the material both matter.

Before moving material

Remove unsuitable material according to the project instructions and establish the formation reference.

Receiving operation and checks

Prepare for the specified compaction and acceptance process. Check levels, moisture and soft areas before the next layer is placed.

A geometric check cannot replace material testing.

Turf Preparation Machinery

Turf preparation machinery creates the final planting condition after the underlying levels and growing layer are ready. Soil movement and seedbed preparation are complementary tasks.

Before moving material

Confirm the intended turf system and growing medium.

Receiving operation and checks

Establish turf and manage irrigation as planned. Check local smoothness and the condition of the planting layer.

A scraper does not perform every agronomic preparation operation.

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.
