Product selection and installation should be clear from the descriptions. Confirm delivery, fixings, preparation, waste and any specialist trade responsibility for the actual job rather than assuming each allowance covers them.
Check the arithmetic
Paving cut and lift: 13.72 m × A$64.75 = A$888.37. Trench excavation: 13.72 m × A$46.25 = A$634.55. All other lines use the same quantity-by-rate calculation and sum to A$6,289.00. Every fixture line lands on an exact cent, so the native PDF subtotal equals the displayed table total.
Measurement to check: Measure channel run, paving cut length, invert level and available outlet route. Selection to check: Keep channel units, grates and pipe fittings distinct from excavation and reinstatement. The PDF uses a 0% tax input only to make its fictional arithmetic visible. Confirm the GST treatment that applies to the actual job and set your own markup before sharing a client quote.
Assumptions and exclusions
Confirm outlet permissions and levels before cutting paving.
Outside this stated scope: No new soakaway, sewer repair or large-area repaving.
No workable outlet or insufficient fall requires redesign rather than an assumed connection. A changed condition should lead to a newly measured quantity, revised allowance or separately agreed task. Keep the client informed of the changed figure before producing another PDF.
