Building Pads — Drainage

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.

Building Pad Preparation

Building-pad preparation should follow the structural and civil brief. A scraper can help place and trim suitable material, but levels and fill condition must be accepted separately.

Before moving material

Confirm the approved pad level, footing zone and inspection requirements.

Receiving operation and checks

Hand over after specified testing and level checks. Compare pad levels with surrounding drainage and proposed floor levels.

A smooth pad is not evidence of engineered fill or a suitable foundation.

Sugar Cane Drainage & Grading

Sugar-cane grading must work with row layout, drainage and repeated harvest traffic. A surface correction should distinguish a temporary rut from a broader drainage restriction.

Before moving material

Identify row-end drains, traffic lines and the crop stage.

Receiving operation and checks

Restore the required track or crop-surface preparation. Inspect low traffic areas and drainage crossings.

Established cane and constrained access may require another method or timing.

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.
