THE ESTIMATING ANSWER
For six low-voltage garden lights, start with a defined scope and measurement basis. Count fixtures, measure cable run and identify transformer location and crossing points. Separate fixtures, transformer and cable allowances. Price the listed tasks separately and state the condition that would require a revision: Unknown buried services or a longer path changes route and quantity.
This guide follows six low-voltage garden lights in Gold Coast, Queensland. 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 electrical contractor. Check the actual site, selected products, supplier figures and labour plan before issuing a client quote.
1. Define the measured job
Install six selected low-voltage lights along one garden path with transformer, cable and a defined shallow route. Count fixtures, measure cable run and identify transformer location and crossing points. 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: Count fixtures, measure cable run and identify transformer location and crossing points. 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
Separate fixtures, transformer and cable allowances. This example has 7 distinct lines, including garden lighting layout, light fitting allowance, transformer and timer allowance. Use actual supplier prices and labour inputs for a customer job; the displayed amounts are fictional document inputs.
Choose before pricing: Separate fixtures, transformer and cable allowances. The fixture separates garden lighting layout, light fitting allowance and transformer and timer allowance rather than hiding all work in one figure.
3. Sequence the work and handoffs
Mock up light positions before trenching and confirm the power source. 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: Mock up light positions before trenching and confirm the power source. Note which stage needs access, a selected product or another trade before the next stage can be priced confidently.
4. Set a change boundary
Unknown buried services or a longer path changes route and quantity. The example excludes mains trench across public land, landscape rebuild or security system. Record the discovery, agree the revised work and update the estimate before adding it to the job.
Change trigger: Unknown buried services or a longer path changes route and quantity. Record the revised task and quantity before it changes the amount your client sees.
Review the Australian job
Confirm the existing supply, route, mounting and testing with the qualified person responsible for this job. Check site-specific approval and inspection requirements before presenting a final price.
The cable and connector allowance line uses 54.86 m. Keep the site measurement and supplier's selling unit together; a material purchase allowance can differ from installed coverage. The amounts are fictional AUD inputs, not current prices for Gold Coast, Queensland or another location.
Worked project calculation
The paired PDF has 7 cost lines. For example, Light fitting allowance is 6 each × A$132.00 = A$792.00; Transformer and timer allowance is 1 set × A$408.00 = A$408.00. 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 |
|---|---|---|---|
| Garden lighting layout | 1 job | A$216.00 | A$216.00 |
| Light fitting allowance | 6 each | A$132.00 | A$792.00 |
| Transformer and timer allowance | 1 set | A$408.00 | A$408.00 |
| Cable and connector allowance | 54.86 m | A$16.00 | A$877.76 |
| Shallow cable route labour | 45.72 m | A$35.50 | A$1,623.06 |
| Light fitting and aiming | 6 each | A$138.00 | A$828.00 |
| Testing and reinstatement | 1 job | A$288.00 | A$288.00 |
| Illustrative total | A$5,032.82 | ||
Adding every exact-cent line gives A$5,032.82. 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
Install six selected low-voltage lights along one garden path with transformer, cable and a defined shallow route.
Outside this example: No mains trench across public land, landscape rebuild or security system.
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
- Count fixtures, measure cable run and identify transformer location and crossing points.
- Separate fixtures, transformer and cable allowances.
- Mock up light positions before trenching and confirm the power source.
- Unknown buried services or a longer path changes route and quantity.
Check business and client details, address, dates, scope, units, line amounts and PDF notes. The garden lighting installation PDF example shows how this fictional project is presented. Its short PDF note is not a substitute for the detailed exclusions above.
