Potholes — Survey Checks

Potholes

A pothole can be a local surface failure or evidence of water and weak support below. The repair method should match its depth and cause.

Before moving material

Inspect the surrounding layer and water entry route.

Receiving operation and checks

Compact the repair and inspect the transition to the existing surface. Check that water is not trapped at the repair edge.

Simply pushing loose soil into a road pothole is not a durable pavement repair.

Surveying for Land Grading

Surveying for grading establishes the relationship between the site and the intended surface. Machine guidance can assist work, but the survey determines the reference against which results are checked.

Before moving material

Define the survey area, control and required deliverables.

Receiving operation and checks

Use the survey to prepare the design and later acceptance checks. Retain the datum, units and control-point descriptions.

A topographic survey and a legal boundary survey serve different purposes.

Existing-Surface Survey

An existing-surface survey records what is present before soil moves. Omitting a drain edge, bank or abrupt grade change can distort the volume model even when point readings are correct.

Before moving material

Identify the work extent and important surface features.

Receiving operation and checks

Compare the surveyed surface with the proposed design. Inspect coverage and gaps rather than relying only on a coloured map.

Survey spacing must reflect terrain and required precision, not a universal grid size.

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.
