Drain Grade Calculator — Building Pad

Capacity and Productivity Calculator

Capacity and productivity answer different questions. Nominal bowl capacity describes a planning load; production depends on load factor, cycle time, soil condition and the volume state being measured.

Before moving material

Identify capacity, realistic load factor and a complete cycle.

Receiving operation and checks

Use the estimate for planning and revise it from observations. Record whether the result is loose, bank or compacted volume.

The calculator produces an operating estimate, not a Dugong performance guarantee.

Slope and Fall Calculator

Fall calculation converts a slope and distance into a change in elevation. It does not decide which slope the project requires. For example, 300 metres at 1 in 5,000 gives a geometric fall of 60 millimetres.

Before moving material

Choose the measurement direction and confirm the units.

Receiving operation and checks

Compare planned end levels and intermediate checks with the design. Check millimetres versus metres and whether the entered distance is horizontal.

The example is geometry only, not an irrigation or drainage design recommendation.

Area and Depth Volume Calculator

An area-and-depth volume estimate is useful for a uniform layer. Length multiplied by width multiplied by average depth gives geometric volume; irregular terrain needs more detailed measurement.

Before moving material

Confirm dimensions and the volume state used.

Receiving operation and checks

Reconcile the estimate with material suitability and placement requirements. For example, 100 by 300 metres at an average 0.01 metre change gives 300 cubic metres.

That example does not establish the volume caused by changing an entire bay's slope.

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.
