Garden subsoil drain installation example — AUD, fictional inputs Work item | Quantity | Unit rate | Amount | Drain route survey | 1 job | A$252.00 | A$252.00 | Service check and protection | 1 job | A$192.00 | A$192.00 | Trench excavation | 27.43 m | A$59.00 | A$1,618.37 | Perforated pipe allowance | 27.43 m | A$32.00 | A$877.76 | Stone and fabric allowance | 1 job | A$744.00 | A$744.00 | Pipe bedding and connection | 27.43 m | A$47.00 | A$1,289.21 | Backfill and turf reinstatement | 1 job | A$624.00 | A$624.00 | Illustrative total | A$5,597.34 | 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 Trench excavation: 27.43 m × A$59.00 = A$1,618.37. Perforated pipe allowance: 27.43 m × A$32.00 = A$877.76. All other lines use the same quantity-by-rate calculation and sum to A$5,597.34 . Every fixture line lands on an exact cent, so the native PDF subtotal equals the displayed table total. Measurement to check: Record run length, trench depth, fall, soil conditions and discharge location. Selection to check: Separate perforated pipe, aggregate and geotextile quantities from digging 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 Trace buried services and confirm discharge before excavation. Outside this stated scope: No basement waterproofing, drainage approval or major landscape reconstruction. Unexpected utilities or no feasible outlet can stop the base design. 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.
