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 a fictional project in Halifax, Nova Scotia: Three exterior light points. Its matching estimate and PDF give each scope decision a visible CAD cost line. Use the document to understand the structure; verify the actual building, product schedule, labour and supplier inputs 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 labour 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 labour 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.
Review the Canadian job address
Have the actual supply route, mounting and testing reviewed by the qualified person doing the work. Confirm any approval or inspection requirements for the project address before issuing a final price.
Count the actual units, site visits and selected products separately. A count in this example is a document input, not a substitute for inspecting the real property. The example amounts are fictional CAD document inputs, not current rates for Halifax, Nova Scotia or another community. A site visit and current supplier information are needed to replace them.
Work through the itemized calculation
Check each extension of quantity and rate in the paired PDF. Two lines from this project are:
- Exterior light allowance: 3 each × C$235.00 = C$705.00.
- Sensor and control allowance: 1 set × C$280.00 = C$280.00.
Adding all 7 rounded line amounts gives C$3,705.00. The PDF shows 0% tax and the same total before any markup. The sample shows 0% tax only to make the arithmetic visible. Determine any applicable GST, HST or PST and markup for the actual work before sharing a quote.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Site and lighting layout | 1 job | C$240.00 | C$240.00 |
| Exterior light allowance | 3 each | C$235.00 | C$705.00 |
| Sensor and control allowance | 1 set | C$280.00 | C$280.00 |
| Cable and weatherproof fittings | 1 job | C$395.00 | C$395.00 |
| Cable routing labour | 10 hours | C$120.00 | C$1,200.00 |
| Luminaire fitting | 3 each | C$205.00 | C$615.00 |
| Testing and aiming | 1 job | C$270.00 | C$270.00 |
| Illustrative subtotal | C$3,705.00 | ||
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.
Keep the product allowance, installation work and any unresolved condition visible as separate decisions. If access or the selected product changes, update the affected quantity or rate and explain the revision before the client relies on the estimate.
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.
Check the business, client, property, dates, line extensions and notes. The outdoor security lighting installation PDF example shows one way to present them. Its short PDF note lists the brief's scope exclusions; the fuller project limits above should guide your own scope.
