Blueprint Auditor

Audit any blueprint. In seconds. Quantity takeoff and code review off the drawing set you are pricing, for general contractors in North America, Europe and Australia.

Upload the set you are pricing and it reads it: quantities, code findings and gaps, each carrying the clause and the sheet it came from.

Shows its gaps: Every audit opens with what the drawings did not carry.
Our own model: No third-party AI in the path. Nothing you upload trains a model.

Counted off the file.

Every door, window, fixture and device the drawing places, counted from its own blocks and grouped by trade. Room areas measured where none was printed.

After award, it keeps working.

Revisions compared issue to issue, change orders scored for exposure and missing backup, and the deficiency list built from the same drawings.

Layers, kept

Switch off everything but walls, or power, or life safety.

Split sets, stitched

Sheets of one plan joined on their grid; a device on the match line counted once.

One trade, or all

Scope an audit to electrical, structural, fire and more.

2D to a 3D model

IFC solids, or a DWG plan extruded, sectioned and measured.

Tender risk

Bonding, liquidated damages and onerous clauses, quoted from the tender.

Eight code packs

Canada, the United States and England. Ontario is the deepest.

Consistency scan

GFA against room sums, counts, ceiling heights.

It grades its own work

Scored against hand-written ground truth; invented output costs as much as missed.

What it costs

From $149 a month, on Field.

Field opens Blueprint Auditor and the AI Estimator; Crew, Pro and Firm include it. No per-sheet or per-project fee, and every code pack is included. One coordination conflict caught before the drawings go out to the trades pays for the month.

The five plans

Your own title blocks, standards or a Procore or Sage connection is a custom setup, from $1,500. What every plan includes →

Which files does it read?

Thirteen formats: DWG back to AutoCAD 2004, DXF, PDF (vector or scanned), PNG, JPG and TIFF sheets, and Excel or CSV schedules, with OCR on every one that needs it. A DWG older than 2004 is named and refused rather than read as an empty drawing.

Which building codes does it check against?

The pack for your jurisdiction. Eight ship today, across Canada, the United States and England. Ontario’s is the deepest, at 105 rules over six categories; younger packs run fewer checks and say so before showing a finding. Every finding cites the article it came from.

What does it cost?

It opens on Field, at $149 a month with the AI Estimator, and is included on Crew, Pro and Firm. Field starts with fourteen days free: no card, up to 3 projects. The five plans.

Where do my drawings go?

To us, and no further. They are processed on Marapone’s own infrastructure, by our own model, in a workspace scoped to your account. No third-party AI vendor is in the path, nothing you upload trains any model, and you can delete a project and its derived data at any time.
