Itemised accessible ventilation duct repair costs

These 7 AUD lines reproduce the native app export. Damaged duct removal is measured as 9.75 m; Replacement duct allowance uses 10.97 m. Some lines are measured work while others are a product or site-task allowance. Read the unit before reusing the structure for a different job.

Accessible ventilation duct repair example — AUD, fictional inputs Work item | Quantity | Unit rate | Amount |

Duct inspection and access | 1 job | A$241.43 | A$241.43 |

Damaged duct removal | 9.75 m | A$51.40 | A$501.15 |

Replacement duct allowance | 10.97 m | A$103.00 | A$1,129.91 |

Duct fitting labour | 9.75 m | A$94.20 | A$918.45 |

Insulation reinstatement | 9.75 m | A$51.40 | A$501.15 |

Airflow check and cleanup | 1 job | A$274.05 | A$274.05 |

Illustrative total | A$3,879.34 |

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

Damaged duct removal: 9.75 m × A$51.40 = A$501.15. Replacement duct allowance: 10.97 m × A$103.00 = A$1,129.91. All other lines use the same quantity-by-rate calculation and sum to A$3,879.34 . Every fixture line lands on an exact cent, so the native PDF subtotal equals the displayed table total.

Measurement to check: Measure damaged run, duct size, joint count and access height. Selection to check: Separate replacement duct, sealant and insulation allowances. 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

Inspect adjacent joints before cutting and verify airflow after repair.

Outside this stated scope: No air-handler replacement, full duct cleaning or concealed ceiling restoration.

Further inaccessible damage requires investigation beyond this local repair. 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.
