Mixed Fill — Surface Drainage

Poor Surface Drainage

Poor surface drainage can result from a blocked outlet, a reversed fall, a damaged crossing or local depressions. Grading should follow the identified cause.

Before moving material

Trace water from its entry point to the receiving outlet.

Receiving operation and checks

Inspect the drainage route during a suitable water event. Check that the complete route remains connected through boundaries and crossings.

Surface grading cannot remedy every subsurface drainage problem.

Misplaced Fill

Misplaced fill may be in the wrong location, wrong layer or wrong volume state. Before relocating it, establish whether it is suitable for the new receiving area.

Before moving material

Identify fill source, condition and intended destination.

Receiving operation and checks

Place the material in the required arrangement and verify the receiving surface. Record where the fill came from and where it went.

Unknown or unsuitable fill should not be spread for convenience.

Excessive Cut-to-Fill Distance

Excessive cut-to-fill distance increases travel time and can make a small-load method inefficient. The first remedy may be better material balancing rather than a larger implement.

Before moving material

Map the cuts, fill deficits and usable haul routes.

Receiving operation and checks

Verify quantities and finish after the selected movement plan. Time a realistic trial including empty return and turns.

Nominal travel speed cannot establish job productivity.

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.
