THE ESTIMATING ANSWER
For two existing radiator positions, start with a defined scope and measurement basis. Measure radiator size, heat-output basis, bracket position and valve connection at each location. Keep radiator products, valves and connection fittings separate. Price the listed tasks separately and state the condition that would require a revision: Corroded nearby pipework or unsuitable output selection changes scope.
This guide follows two existing radiator positions in Albury, New South Wales. The matching itemised estimate and PDF show how the job brief becomes measured quantities and separate AUD amounts. The responsible role in this scenario is mechanical contractor. Check the actual site, selected products, supplier figures and labour plan before issuing a client quote.
1. Define the measured job
Replace two selected hydronic radiators at existing accessible positions, reconnecting suitable pipework and testing the system. Measure radiator size, heat-output basis, bracket position and valve connection at each location. Record the measurements and existing condition in the estimate before turning quantities into line items. The scope should make clear why this is a separate project from a broader renovation or maintenance quote.
Measure for this job: Measure radiator size, heat-output basis, bracket position and valve connection at each location. Put that measured basis beside the relevant PDF lines so area, fitted length and product purchase quantities stay distinct.
2. Build a product and labour schedule
Keep radiator products, valves and connection fittings separate. This example has 7 distinct lines, including system and position survey, drain-down and protection, radiator allowance. Use actual supplier prices and labour inputs for a customer job; the displayed amounts are fictional document inputs.
Choose before pricing: Keep radiator products, valves and connection fittings separate. The fixture separates system and position survey, drain-down and protection and radiator allowance rather than hiding all work in one figure.
3. Sequence the work and handoffs
Confirm isolation, drain-down and refill plan before removing old units. Show which task depends on access, a selected product or another trade. If that dependency is still open, label the price preliminary and identify the information needed before a firm quote.
Plan the handoffs: Confirm isolation, drain-down and refill plan before removing old units. Note which stage needs access, a selected product or another trade before the next stage can be priced confidently.
4. Set a change boundary
Corroded nearby pipework or unsuitable output selection changes scope. The example excludes boiler replacement, new pipe routes or whole-system balancing. Record the discovery, agree the revised work and update the estimate before adding it to the job.
Change trigger: Corroded nearby pipework or unsuitable output selection changes scope. Record the revised task and quantity before it changes the amount your client sees.
Review the Australian job
Inspect the existing surface, access, product schedule and handoff conditions. Resolve unknown work and confirm any specialist requirements before giving a client a final quote.
The radiator allowance line counts 2 each. Verify the actual locations and product schedule rather than carrying this fictional count into another property. The amounts are fictional AUD inputs, not current prices for Albury, New South Wales or another location.
Worked project calculation
The paired PDF has 7 cost lines. For example, Radiator allowance is 2 each × A$504.00 = A$1,008.00; Valve and fitting allowance is 2 set × A$198.00 = A$396.00. Each amount comes from the stated quantity and unit rate, so you can trace the arithmetic back to the job scope.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| System and position survey | 1 job | A$234.00 | A$234.00 |
| Drain-down and protection | 1 job | A$300.00 | A$300.00 |
| Radiator allowance | 2 each | A$504.00 | A$1,008.00 |
| Valve and fitting allowance | 2 set | A$198.00 | A$396.00 |
| Radiator fitting labour | 2 each | A$468.00 | A$936.00 |
| Refill and leak check | 1 job | A$294.00 | A$294.00 |
| Old unit disposal | 1 job | A$180.00 | A$180.00 |
| Illustrative total | A$3,348.00 | ||
Adding every exact-cent line gives A$3,348.00. 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. A fictional rate is a document input, not a market quote or a recommended selling price.
Scope and pricing boundaries
Replace two selected hydronic radiators at existing accessible positions, reconnecting suitable pipework and testing the system.
Outside this example: No boiler replacement, new pipe routes or whole-system balancing.
Separate product allowances, supply, installation, disposal and any specialist work where the actual project needs them. If access or a hidden condition changes, document the affected scope and agree a revised price instead of silently extending the base amount.
Before you send the estimate
- Measure radiator size, heat-output basis, bracket position and valve connection at each location.
- Keep radiator products, valves and connection fittings separate.
- Confirm isolation, drain-down and refill plan before removing old units.
- Corroded nearby pipework or unsuitable output selection changes scope.
Check business and client details, address, dates, scope, units, line amounts and PDF notes. The hydronic radiator replacement PDF example shows how this fictional project is presented. Its short PDF note is not a substitute for the detailed exclusions above.
