Cable quantity estimating workflow
How to prepare route segments, repeated runs, spare length, waste allowance and unit cost before using the Australian cable quantity calculator.
Quantity-estimate purpose
Cable quantity estimating converts route measurements into a material row. It can show order quantity, material cost and drum count when the user provides the inputs.
It does not decide the cable type, cable size, installation method or procurement direction.
Workflow
- Record the cable description and source.
- Measure route segments for one run.
- Enter repeated-run count where the same route basis applies.
- Add spare length per run separately from waste.
- Enter waste percentage and unit cost with a traceable source.
Quantity table
| Field | Record | Review concern |
|---|---|---|
| Cable description | Schedule, product or quote line | Quantity is weak if cable is unknown |
| Route segments | Measured route sections | Drawing shortcuts can understate length |
| Identical runs | Number of repeated routes | Must really share the same basis |
| Spare length | Tails, terminations or handling allowance | Should not be hidden in waste |
| Unit cost | Supplier or internal rate | Can become stale |
Boundaries
- Do not use the quantity result as cable sizing.
- Do not hide measurement uncertainty.
- Do not treat material cost as a full quote.
- Do not issue procurement decisions from the calculator output alone.
