Council Works Team — Drainage Correction

Councils & Public Works

Council and public works briefs should state the asset outcome, scope boundaries and evidence needed for acceptance. Naming a machine too early can obscure whether the work requires design, bulk excavation or surface correction.

Before moving material

Identify the asset owner, procurement brief and work-zone controls.

Receiving operation and checks

Record the verified result and any work outside the contractor's scope. Check that the completed work answers the brief rather than a machine-based promise.

No council endorsement, supplier approval or procurement status is implied.

Rough Grading Correction

Rough-grade correction starts by deciding whether the mismatch is local or distributed across the whole area. A local touch-up is efficient only when the larger formation is already sound.

Before moving material

Survey enough of the area to locate the extent of error.

Receiving operation and checks

Remeasure corrected areas against unchanged reference points. Check that the repair has not moved the error into an adjacent zone.

A repeated failure may require a revised design or foundation repair.

Surface Drainage Formation

Surface drainage formation gives runoff a connected route. Forming a depression without checking its outlet can simply relocate the ponding.

Before moving material

Identify catchment entry, the receiving outlet and levels along the route.

Receiving operation and checks

Stabilise the surface and inspect it during a suitable water event. Check continuous drainage through every join and crossing.

A grading pass does not size a drainage system or authorise discharge onto another property.

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.
