What Is Crossfall?

Incorrect Crossfall

Crossfall controls the change in level across a road, path or other surface. A correct centreline does not prove that the edges drain correctly.

Before moving material

Measure the cross-section at the affected location.

Receiving operation and checks

Check the corrected section and the neighbouring transition sections. Verify both edges and any gutter or drain connection.

Do not infer a road crossfall specification from a generic illustration.

Crossfall Control

Crossfall control sets the transverse profile separately from longitudinal grade. Roads and other surfaces can require a crown, one-way fall or transitions between profiles.

Before moving material

Identify the designed cross-section and its changes along the asset.

Receiving operation and checks

Verify adjoining sections so the profile changes smoothly. Check ties to drains, gutters and existing surfaces.

Machine tilt indication is not a substitute for final cross-section measurement.

Building Pad Surface Handover

A building-pad handover must identify the formation, level reference and evidence for the intended foundation work. Geometry and material suitability are separate acceptance questions.

Before moving material

Obtain the structural and civil requirements for the pad.

Receiving operation and checks

Provide the builder with accepted level and material records. Check thresholds and surrounding runoff as well as the pad surface.

This guide does not establish bearing capacity or certify engineered fill.

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.
