How does AI takeoff work?
AI takeoff turns a plan set into structured quantities through computer vision, pattern recognition and code reasoning — then hands the estimator a confidence-scored result to review. Here's the process, step by step.
The process, step by step
AI takeoff software is trained on thousands of construction plans so it can recognize symbols, objects and dimensions. In use it: (1) ingests the uploaded plan set and specs; (2) classifies and detects elements — devices, fixtures, equipment, walls, runs; (3) measures lengths and areas and counts symbols; (4) reconciles those counts against schedules and the one-line; (5) structures the quantities and passes them to the estimator to review, adjust and validate. The estimator stays in control — the AI does the counting, the human does the judgment.
How Pilars does it
Pilars adds two steps most tools skip: it reads the specification book alongside the drawings, and it checks the result against building codes. Every quantity comes back with a confidence score sourced to the sheet it came from, so the estimator's review goes straight to the lines that need a human eye.
Everything Pilars does
Reads the whole set + spec book
Pilars reads every sheet and the specification book together, resolving references across sheets and schedules — not just one floor plan in isolation.
Trade-specific models
Counts devices, fixtures and equipment and traces runs across 48 CSI divisions — real trade takeoff, not generic area measurement.
Code-compliance flagging
Every takeoff is checked against IBC, NEC, IPC, IMC, ADA and NFPA, so compliance risk surfaces before the bid goes out.
Confidence score on every line
Each quantity carries a confidence score sourced to the exact sheet, so review is fast, targeted and defensible to the GC.
Cross-sheet reasoning
Resolves door, window and fixture schedules and one-line references the way a senior estimator would — catching scope the plan alone hides.
Cloud, with clean exports
Nothing to install. Export bid-ready quantities to Excel, Sage, WinEst and your estimating tool of choice.
Why estimating teams choose Pilars
- 8x faster bidding — a multi-hour takeoff becomes a short review of confidence-scored quantities.
- 94% takeoff coverage on the first pass, so estimators refine rather than rebuild.
- Bid 2–3x more jobs without hiring — and for subs, win rate rises with bid volume.
- $100 per trade, per plan — no per-seat licenses, unlimited projects.
- Quantities sourced to the sheet with a confidence score — defensible to owners and GCs.
Frequently asked questions
What technology does AI takeoff use?
A combination of computer vision (to read the drawing), machine learning and pattern recognition (trained on thousands of plans to recognize symbols and elements), and code reasoning (to apply standards like NEC or IBC without hallucinating).
How long does an AI takeoff take?
Minutes to a couple of hours of processing plus review, versus the 16–40+ hours a manual commercial takeoff can take. In benchmarks a ~22-hour electrical takeoff becomes ~2–3 hours of review.
Does the estimator still review the output?
Yes — always. AI is used as a fast, accurate first pass; the estimator reviews confidence-scored output, refines low-confidence items, and applies scope and site judgment.
Can AI takeoff read the specification book?
Most tools only read drawings. Pilars reads the spec book alongside the drawings and resolves schedule references, so scope buried in the specs is captured.
What file types can AI takeoff read?
Typically 2D PDFs and plan sets. Clean, vector or high-resolution scans work best; very low-DPI or heavily hand-drafted sheets reduce accuracy and need more review.
How much does Pilars cost?
Pilars is $100 per trade, per plan, with no per-seat licenses and unlimited projects — so a shared estimating team scales without seat creep.
Which trades does Pilars support?
Electrical, plumbing, HVAC, concrete and rebar, drywall, doors and windows, finishes, flooring, structural steel, roofing and millwork — trade-specific models across 48 CSI divisions.
Does Pilars replace estimators?
No. Pilars automates the extraction and validation — the counting, measuring, reconciliation and code checks — while the estimator owns pricing, scope judgment and risk. It removes the bottleneck, it doesn't remove the expert.
Does Pilars read specifications, not just drawings?
Yes. Pilars reads the spec book alongside the drawings and resolves references across sheets and schedules, so scope that lives in the specs is captured in the takeoff.
