Pre-Road-Base Grading

Civil Construction

Civil construction grading sits within a design, material and inspection sequence. The useful question is which layer is being handed to which contractor, not whether the site merely looks level.

Before moving material

Confirm approved drawings, services and inspection hold points.

Receiving operation and checks

Verify the completed layer before the next trade covers it. Record levels, material records and unresolved defects together.

Dugong may suit controlled redistribution; deep excavation and engineered fill acceptance need their own methods.

Road Construction

Road construction requires coordinated longitudinal grade, crossfall, material layers and drainage. Fine shaping should follow an accepted underlying formation rather than conceal its defects.

Before moving material

Set out the road alignment and drainage connections.

Receiving operation and checks

Compact and inspect before placing the next road layer. Check edges, transitions and outlet continuity in addition to centreline levels.

Road design and traffic management are project-specific responsibilities.

Road-Base Preparation

Road-base preparation controls a specified aggregate layer, not ordinary topsoil. Even distribution and the right shape help the compaction and surfacing operations that follow.

Before moving material

Confirm aggregate type, accepted subgrade and planned layer thickness.

Receiving operation and checks

Compact and complete the project's layer-acceptance checks. Measure levels and thickness at representative locations and transitions.

Do not use a nominal scraper load count as evidence of compacted layer depth.

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.
