AUDIT ANY BLUEPRINT.
IN SECONDS. Blueprint Auditor — construction quantity takeoff and drawing review software for general contractors in North America and Europe

Drop in a drawing set and the engine reads it live — a real quantity takeoff (room areas, door, window and fixture counts), plus sheets, disciplines, completeness gaps and code risk, computed from your file. First results are free; the full coordinated audit runs in your private build.

Reads text/vector PDFs (Revit, AutoCAD, Bluebeam exports) · scanned sets are OCR'd in your private build. Processed in memory, never stored.

From drawing to done

FOUR STEPS. NO SPREADSHEETS.

Drop a file and the pipeline handles ingestion, extraction, code audit and reporting — review the output and ship it.

01

DROP A DRAWING

DWG, PDF, DXF, image, or schedule. Scanned sheets are OCR'd automatically.

02

EXTRACT

Rooms, areas, openings and quantities are read off the geometry and schedules.

03

AUDIT

Every sheet is checked against OBC, AODA, fire, zoning and green-standard rules.

04

REPORT

Takeoff, costed estimate and a client-ready Excel/PDF audit — generated for you.

What it reads

IT TAKES THE DWG.

Most takeoff tools ask for a PDF. Drawings are issued as DWG, so the first thing you do is export one — losing the layers, the blocks and the exact coordinates the drawing was authored with, then paying a reader to guess them back off a picture. This one opens the file the architect sent.

DWG

AutoCAD 2004 and later, read directly. Pre-2004 is named and refused rather than silently read as an empty drawing.

DXF

Any CAD export. Room boundaries are measured from the geometry itself, so areas the drawing never printed are still computed.

PDF

Vector or scanned. A set plotted from CAD carries no text layer at all — those are read from the line work, not photographed.

SHEETS

PNG, JPG and TIFF, plus Excel and CSV schedules. Thirteen formats in all, with OCR on every one that needs it.

On the drawing itself

TAKE THE SHEET APART.

A drawing is organised by layer, and most tools throw that away the moment they turn it into a picture. This one keeps it. Open the drawing and switch off everything that is not the thing you are checking — walls, doors, glazing, power, life safety, structure, dimensions, hatching — and read what is left without the rest of the sheet on top of it.

GROUPED THE WAY YOU THINK

A sheet carries thirty-plus layers with names like A-WALL-PATT. They arrive grouped under the system they belong to, so one control turns off walls rather than four.

IT READS THE DRAWING'S OWN LANGUAGE

Layers drawn in Spanish or French are read as what they are — puertas y ventanas is doors and windows — and anything it cannot read keeps its own name rather than being filed under a guess.

PDFS TOO, WHERE THEY HAVE LAYERS

A PDF plotted from CAD usually keeps its layers. Those work exactly the same way. A scanned sheet has none, and gets the rendered page instead — the file decides, not a setting.

Counted, not estimated

WHAT THE FILE ALREADY KNOWS.

A CAD drawing states its own contents. Every door tag, window tag, fixture and device is a placed block the file can be asked about, so those counts are the drawing's own rather than anybody's estimate — and the report says which is which, because a count read from the file and a symbol recognised on a scan are not the same kind of fact.

  • •Every placed symbol grouped and counted, with its legend description where the sheet has a legend
  • •Door, window and room schedules read as tables, including two-sided electrical panel schedules
  • •Room areas measured from the boundary when the drawing never printed one
  • •Stairs, risers, goings and guards checked against the code you build under
And what nobody else does

IT CHECKS THE CODE

Estimating tools count what is drawn. This one measures the building and then holds it against the code you build under — 110+ checks, each one citing the article it came from, so a finding can be verified rather than trusted.

IT TELLS YOU WHAT IT COULDN'T SEE

Every audit opens with how much of what it needed was actually on the drawings, and lists every assumption it had to make to finish. A tool that hides its gaps is a tool you have to check twice.

IT KNOWS WHERE YOU BUILD

Seven jurisdictions carry shipped rule coverage across Canada and the United States, and the report cites that jurisdiction's own articles. Ontario, British Columbia and California are verified — every rule checked against the authority by someone other than whoever wrote it. Florida, New York City and the National and International model-code baselines check the requirements those places adopt unchanged, and say so before showing you a finding rather than letting a pass read as more than it is. Where a region has no rule set yet, the report says that too rather than quoting the wrong code at you.

ONE TRADE, OR ALL OF THEM

Scope an audit to electrical, structural, mechanical, doors and hardware, low voltage or fire protection before you upload — and get that trade's findings instead of reading past a hundred that belong to somebody else.

IT MEASURES ITSELF

Extraction accuracy is scored against drawings with hand-written ground truth, and invented output is charged at the same rate as missed output. Nothing here quotes a number that did not come out of that harness.

NOTHING LEAVES YOUR WORKSPACE

The model runs on our own hardware, not on a commercial AI API. Your drawings are not sent to a third party, and they are not training anybody's model.

Inside the app

WHAT IT LOOKS LIKE RUNNING.

Real screens from a live build, recorded on an actual drawing set — not mock-ups. Every one of these runs on your own hardware, on your own drawings, with nothing leaving the network.

01 — Quantity takeoff

MEASURED OFF THE SHEETS.

Rooms, areas, doors, windows and fixtures pulled straight out of the drawing set and the schedules — with every line traceable back to the sheet it came from.

  • ▸Room-by-room areas with a live total
  • ▸Door, window and fixture counts off the schedules
  • ▸Metric and imperial handled automatically
  • ▸Exports as JSON straight into the AI Estimator
02 — Code & coordination audit

WHAT THE DRAWINGS CONTRADICT.

The full set checked against the code pack for your jurisdiction and against itself — clause references included, so a finding can be taken to the consultant rather than argued about. The example shown runs the 2024 Ontario Building Code.

  • ▸OBC, AODA, fire and zoning checks with clause references
  • ▸Cross-discipline coordination conflicts
  • ▸Scope gaps between the specification and the drawings
  • ▸Severity-ranked so you read the expensive ones first
03 — Tender risk

THE CLAUSES THAT COST MONEY.

The bid documents read for the terms that carry real exposure — bonding, liquidated damages, fair wage, restricted hours, sole-source products — before you commit to a number.

  • ▸Onerous clause detection across the tender package
  • ▸Bonding and insurance requirements surfaced
  • ▸Liquidated damages and schedule exposure flagged
  • ▸Each finding quoted with its source excerpt
04 — Change orders & deficiencies

AFTER AWARD, IT KEEPS WORKING.

The same engine tracks revision-to-revision drift and builds the deficiency list, so the exposure you priced at tender is the exposure you can still see at closeout.

  • ▸Revision compare — what changed between issues
  • ▸Change-order risk tracked against the original scope
  • ▸Deficiency lists generated and cross-referenced
  • ▸RFI backlog checked against the current drawings

Five tools, one job

MEASURE IT. CHECK IT. PRICE IT. LEVEL IT. BUY IT OUT.

These are five of the eight products — the ones that price and win the job. (The other three, FloatGuard, TradeVet and CostLine, pick it up after award.) Most contractors only have one or two of the five. Buy the one you’re missing — or run all five and the same job carries straight through from the drawing set to the awarded subcontract.

Stage 1 — before the bid

Blueprint Auditor

Reads the drawing set and answers how much is there — quantities, scope gaps, code and tender risk.

You are here · Field plan
Stage 2 — before you order

SpecChecker

Reads the manual against the drawings and answers do the documents agree — before the material is ordered.

See it →
Stage 3 — at the bid

AI Estimator

Takes those quantities and answers what should we bid — assemblies, contingency, municipal soft costs, margin.

See it →
Stage 4 — before you award

Bid Leveler

Reads the quotes that came back and answers whose bid is actually cheapest — a dozen formats, one scope.

See it →
Stage 5 — after you win

ScopeGuard

Takes the awarded job and answers did anyone actually price it — every sub’s letter against your own documents.

See it →

Each one works on its own — Field opens two, Pro opens all five. All five together is the Pro plan at $249 a month, five seats, and the auditor’s takeoff imports straight into the estimator rather than being retyped.

What a plan actually opens

THE FULL PROGRAM, EVERY PLAN.

No metering, no per-sheet fee, no feature gate. The working app on day one, and cancel any month from your dashboard if it doesn’t earn its keep.

The arithmetic

One coordination conflict caught before the drawings go out to the trades is the entire month's subscription — that is the conversation you don’t have as a change order six months later.

The floor holds from the other end too: if it isn’t saving you real hours, cancel any month from your dashboard — no retention call, no form. Estimators tell us drawing review runs four to six hours before every trade meeting, and a full day per tender takeoff.

Included in every plan

  • ✓The complete program the moment you sign in — nothing to install, no licence key, no machine to provision
  • ✓Unlimited drawings, sheets, projects and machines in your company. No per-sheet or per-project fee, ever
  • ✓Every code check in your jurisdiction’s pack, at no extra cost — seven ship today across Canada and the United States. Ontario is the deepest, at 105 rules spread over its own six code categories (OBC, AODA, Ontario fire code, Toronto zoning, the Green Standard and the trade engines: OESC electrical, NFPA 80 door hardware, TIA-568 low voltage), and it is the standard the rest are built to
  • ✓Thirteen file types, counting each supported DWG release back to 2004 on its own — plus PDF and scanned PDF, DXF, drawing images and Excel or CSV schedules, with OCR built in
  • ✓Scope an audit to one trade — electrical, structural, mechanical, doors and hardware, low voltage or fire protection — or run all of them
  • ✓Takeoff, costed estimate, RFI, deficiency and change-order lists, as Excel and client-ready PDF
  • ✓Every improvement the day it ships — no version to buy, no upgrade to schedule
  • ✓Seven free days first, then cancel any month from your dashboard — no long-term contract

Not included — that’s a customised setup

From $1,500

  • ✗Fine-tuning on your drawing conventions, title blocks, standard details and past project sets
  • ✗Your own internal design standards, or extending a jurisdiction pack beyond the depth of the shipped reference pack
  • ✗Wiring into Procore, Sage, Bluebeam or your own document management system
  • ✗Workflows the product doesn’t cover — RFI backlogs, daily logs, meeting minutes, change-order tracking
  • ✗Bespoke development beyond the eight programs — that is quoted as project work

Buying the product first doesn’t lock you out of a build later — most teams start here, then commission the parts that are specific to them. See custom builds →
