Read the drawing
LumenTakeoff works from the structure and geometry inside supported PDFs instead of relying on visual guesses alone.

Counted from plan geometry
LumenTakeoff reads electrical plan geometry to turn repeated lighting symbols into exact, reviewable fixture counts.
You keep control of scope and naming. The repetitive counting happens underneath.

The film
One minute. The lights come on.
From a PDF to an exact, reviewable count. Every fixture in the film sits where the engine actually found it on the demo set.
01The manual problem
Estimators shouldn’t spend their best hours counting the same symbol 200 times.
Lighting takeoffs are repetitive, high-stakes work. LumenTakeoff handles the repeated counting so the estimator can stay focused on scope, exceptions, and the bid.

02The difference
Built for counts that have to be right.
A quantity that goes into a bid has to be defensible. Every number LumenTakeoff produces can be traced back to the geometry and the sheet it came from.
02
Count by family
Repeated fixture geometry becomes one family, one quantity, and one review decision.

Schedule, legend, prior confirmation, or unresolved. The product shows why a name or scope decision is being suggested.

03The takeoff
From plan set to reviewable takeoff.
One sheet, one family, one panel of evidence. The plan stays the main object — not a dashboard wrapped around it.

The drawing does not resolve this one. The estimator decides.

04How it works
Plans in. Reviewed quantities out.
- Step 1
Upload plans
Supported vector PDFs enter the takeoff pipeline.
- Step 2
Find families
Repeated lighting geometry is grouped and counted.
- Step 3
Resolve scope
New, existing, relocated, demolition, or review-required.
- Step 4
Review evidence
Schedule, legend, prior confirmations, and ranked suggestions are shown separately.
- Step 5
Confirm once
One estimator decision applies to the whole family and can help the next project.
05Human control
The machine counts.
You decide.
LumenTakeoff is designed to automate repetition without hiding uncertainty. If the drawing does not support a confident answer, the estimator sees the ambiguity instead of a fabricated result.

37 fixtures

Ambiguous4 variants
Junction box
The legend carries 4 variants of this symbol across 31 instances. Pick one, or leave it open.
UnresolvedName required
9 instances
The count is exact. The drawing never names the type. It stays unnamed.
An unnamed exact count is acceptable. A confidently wrong name is not.
06Naming ledger
Confirm it once.
Start ahead next time.
When an estimator confirms a fixture family, LumenTakeoff retains that decision within the appropriate firm and project context, so repeat drawing styles arrive with less to review.
Project AE-201
Midtown Medical Office
A12x4 recessed troffer
Estimator confirmed
The estimator reviews the family once and confirms the type against the schedule.
Project BE-204
Riverside Clinic Fit-Out
A12x4 recessed troffer
Prior confirmation
The same geometry appears in a new plan set. The prior confirmation arrives as evidence — not as an answer.
Confirmed knowledge, scoped to your firm. The estimator still makes the call on every project.

LumenTakeoff is early and in active development with electrical estimators. Percentages get published here when they are measured, not before.
Validated on real project plan sets
Development runs against production electrical drawings, not synthetic test fixtures.
Compared against manual takeoffs
Counts are checked against the hand takeoff an estimator would have produced.
Built with estimator review in the loop
The review workflow is shaped by the way estimators already work a plan set.
Exact counting where the route supports it
Deterministic counting on supported vector geometry — and a visible flag where it isn't.
