Lighting takeoff
Counting lighting points: fixtures, types and notes to check
A lighting count is easier to price when each quantity has a fixture type, a location and a clear work status. Keep those details beside the count so you can check the quotation against the drawing.
Use this guide to count the visible lighting items, compare them with the referenced schedule and record any difference before you apply rates.
1. Set the drawing and lighting references
Record the drawing number, revision and quoted area. Locate the legend, lighting schedule and referenced notes for that set. If a detail or schedule is on another sheet, keep its reference with your count.
Start with the electrical drawing legend register. Record the full type label, including any suffix, rather than grouping every lighting mark into one total.
Check what the drawing uses each mark to represent. Confirm whether nearby text describes a fixture type, a quantity, a location or another reference. Keep unclear labels on a questions list until the relevant drawing information resolves them.
2. Count each fixture type and work status separately
- Choose one area and one fixture type for each counting pass.
- Mark each counted location on a working copy and record the area subtotal.
- Keep different fixture types and variants in separate rows while reviewing the quotation.
- Record the drawing’s qualifications for new, existing, retained, removed or relocated items when shown.
- Compare overlapping layouts and details before adding an item that may already be represented in the tally.
A retained item still needs a scope decision. Record any associated work that the job includes. If the supplied drawing does not make the intended work clear, list that as a question instead of deciding from the symbol alone.
Use the room-by-room takeoff worksheet to keep area subtotals traceable. If work is interrupted, leave the last counted mark and next position in the counting pause record.
3. Compare the plan tally with the schedule
Check the matching type entry in the referenced lighting schedule. Read its description and notes, then compare any stated quantity with the tally for the same area and scope. Keep the plan quantity and schedule quantity in separate columns during this check.
If the two quantities differ, locate the difference before setting the final quotation quantity. Check revisions, quoted boundaries, repeated views, item status and whether a note changes what a mark represents. Keep the discrepancy visible until it is resolved.
Do not add the plan count to the schedule count as though they describe separate sets of fixtures. If the sources conflict and you cannot reconcile them, record the exact references and ask for clarification through the project’s usual process. Record the answer with the estimate.
4. Use this fictional fixture worksheet
This example describes Office D on drawing E-05, revision D, with schedule LS-01. Its invented labels L-A and L-B identify two luminaire types for this example only. The plan shows six new L-A items, two new L-B items and two existing L-A items marked to remain unchanged.
| Item and status | Plan tally | Schedule or note | Review decision |
|---|---|---|---|
| L-A, new | 6 items | Schedule lists 7 | Q-01: resolve the one-item difference |
| L-B, new | 2 items | Schedule lists 2 | Quantities match for this area |
| L-A, retained | 2 items | Retain unchanged; no related work in this example’s scope | Keep separate from new work |
| Quotation review | Keep type rows separate | New L-A quantity still pending | Hold affected pricing for Q-01 |
The six new L-A marks and seven scheduled L-A items leave a difference of one item. They do not make thirteen new L-A items. The two new L-B items remain a separate type. The two retained L-A items are outside the new-work rows under the stated fictional scope.
For your own worksheet, add room or area, sheet and revision, schedule reference, type description, quotation unit and question owner. When Q-01 is answered, update the affected quantity and keep the clarification reference beside the change.
5. Confirm the priced work before transferring the count
Review the description for each fixture type before pricing it. Check the agreed supplied item and accessories, the installation work and any related task lines. Record the information needed for other work, such as wiring, access or making good, instead of assuming the fixture tally describes it all.
Use the point-scope worksheet to define what one quotation unit covers. Keep the unit consistent between the count, the rate and the final line description.
- Have all quoted areas been checked, with a subtotal for each fixture type?
- Are type labels and different work statuses still visible?
- Have plan and schedule differences been reconciled or held as open questions?
- Are the item descriptions, quotation units and included tasks clear?
- Can another estimator trace each final quantity back to the reviewed drawing references?
