THE ESTIMATING ANSWER
For three exterior light points, start with a defined scope and measurement basis. Record mounting height, coverage direction, cable routes and switching positions for each light. Separate luminaire, sensor and weatherproof fitting allowances. Price the listed tasks separately and state the condition that would require a revision: Hidden cable routes or inadequate supply protection change the design.
This guide uses three exterior light points as a worked, fictional job. Its matching itemized estimate and PDF let you trace the advice to actual document lines. The role considered here is electrical contractor. Confirm the site conditions, product selections and your own costs before preparing a client quote.
1. Define the measured job
Install three selected exterior security lights on accessible walls using confirmed suitable supply routes and controls. Record mounting height, coverage direction, cable routes and switching positions for each light. 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.
Measurement basis: Record mounting height, coverage direction, cable routes and switching positions for each light.
2. Build a product and labor schedule
Separate luminaire, sensor and weatherproof fitting allowances. This example has 7 distinct lines, including site and lighting layout, exterior light allowance, sensor and control allowance. Use actual supplier prices and labor inputs for a customer job; the displayed amounts are fictional document inputs.
Selections to confirm: Separate luminaire, sensor and weatherproof fitting allowances.
3. Sequence the work and handoffs
Confirm supply, access and control logic before fixing or drilling. 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.
Work sequence: Confirm supply, access and control logic before fixing or drilling.
4. Set a change boundary
Hidden cable routes or inadequate supply protection change the design. The example excludes new main panel, CCTV installation or high-level access equipment. Record the discovery, agree the revised work and update the estimate before adding it to the job.
If the job changes: Hidden cable routes or inadequate supply protection change the design.
Worked project calculation
The example line for exterior light allowance is 3 each × $185.00 = $555.00. This line is one part of the complete 7-item estimate and uses a fictional unit rate.
The paired estimate has 7 separate lines. For this fictional job, multiply each quantity by its unit price and add the line amounts to get $2,915.00. The sample PDF uses these exact values, with tax and markup left at zero so the arithmetic is visible. This total is an illustration, not a regional price or an offer to perform the work.
| Cost line | Quantity | Unit price | Line amount |
|---|---|---|---|
| Site and lighting layout | 1 job | $190.00 | $190.00 |
| Exterior light allowance | 3 each | $185.00 | $555.00 |
| Sensor and control allowance | 1 set | $220.00 | $220.00 |
| Cable and weatherproof fittings | 1 job | $310.00 | $310.00 |
| Cable routing labor | 10 hours | $95.00 | $950.00 |
| Luminaire fitting | 3 each | $160.00 | $480.00 |
| Testing and aiming | 1 job | $210.00 | $210.00 |
| Illustrative subtotal | $2,915.00 | ||
Scope and pricing boundaries
Install three selected exterior security lights on accessible walls using confirmed suitable supply routes and controls.
Outside this example: No new main panel, CCTV installation or high-level access equipment.
Separately identify supplier allowances, labor, subcontracted work and site-specific risk where they apply. Before giving a selling price, decide how your own overhead, profit and any applicable tax will be handled. Do not copy the fictional rates into a real quote without checking your own measurements and supplier or subcontractor figures.
Before you send the estimate
- Record mounting height, coverage direction, cable routes and switching positions for each light.
- Separate luminaire, sensor and weatherproof fitting allowances.
- Confirm supply, access and control logic before fixing or drilling.
- Hidden cable routes or inadequate supply protection change the design.
