First set of eyes on every construction drawing.
MarkedUp is the audit layer for construction drawings. Catch sheet index, callout, door-schedule, keynote, and MEP errors before they become rework, delays, and claims. Resolve issues with a 1-click RFI. We don't train on your project files. Unlimited users, one flat quarterly or annual price.

PDF in. Audited PDF out. You never leave your tools.
MarkedUp is an intelligent invisible layer inside the tools you already trust. While others provide a "first-pass," MarkedUp provides a final audit.
Step 1: Drop in your PDF set
Upload your architectural, structural, and MEP drawings. We handle the heavy lifting.
Step 2: View your MarkedUp PDF
We export all found issues as standardized markups directly into a PDF opened in Bluebeam, Autodesk, Procore, or wherever you manage PDFs today.
Step 3: Bid and build better
Your team resolves them exactly as they do today, just without the manual searching grind.

Know the price before you run the audit.
Book a meeting. We run a project with you, then start a 90-day pilot at $1,500 per office. After the pilot, renew at $1,500 per quarter per office or switch to $5,000 per office per year.
Results may be held if drawing quality isn’t audit-ready. We don’t promise every upload gets a full pack.
90-day pilot
$1,500 / office

Drawing errors are inevitable. Find them before you bid, build or share with MarkedUp.
Whether you issued the set or you're about to build from it, undetected errors cause the same damage: rework, RFIs, back-charges, and blown schedules.
Precon & Estimating
Don't lock your GMP on uncoordinated bid sets.
- Catch missing details before subcontractors issue exclusions.
- Audit large bid sets during the bidding crunch.
- Protect your fee from day-one, easily avoidable change orders.
Architects
Elevate QA/QC standards without adding billable hours.
- Callout references to moved/deleted details.
- Sheet indexes out of sync.
- Door schedule mismatches.
VDC/BIM Managers
You're drowning in coordination.
- Broken callout references nobody flagged.
- Sheet index drift that creates scope gaps.
- Door schedule mismatches that become procurement emergencies.
GC Ops teams
Protect project margins by catching coordination gaps.
- Prevent field RFIs caused by dead-end callouts.
- Eliminate scope gaps hidden in misaligned sheet indexes.
- Stop wrong material orders due to plan-to-schedule mismatches.

Other tools offer a first-pass. MarkedUp provides a final audit.
Generic LLMs hallucinate, and basic construction AI tools only scan text. MarkedUp reads drawing geometry, symbols, and cross-sheet references, then returns Bluebeam-ready findings.

The story behind MarkedUp.
As a construction engineer, I watched my wife's brother lose $100,000 on a single project because of errors nobody caught. I built MarkedUp so nobody, architect or GC, ever absorbs that loss again.

Frequently Asked Questions
An invisible audit layer that catches drawing errors before they become rework, delays, and claims. View and manage issues in the tools you already use: drag-and-drop, or audit files directly in SharePoint, Autodesk, Trimble, Procore and more.
No. No new system of record. No dashboard to remember. Just findings where your team already works.
As markups on your drawings, in the tools your team already uses. With Bluebeam Session, MarkedUp pushes flagged markups into the Studio Session you already run. With a connected folder in Autodesk Forma, Google Drive, Trimble Connect, Trimble ProjectSight, or Microsoft SharePoint, the marked-up result comes back to that folder. Procore can auto-create RFIs, and Slack or Microsoft Teams notifications keep the team in the loop.
ConstructionProof is the drag-and-drop path into MarkedUp. Upload a PDF drawing set, get a scoped integrity audit back, and open the findings where your team already works. The name is the ease pun (so easy it’s construction-proof), not a second product.
Live today: Bluebeam Session, Autodesk Forma, Google Drive, Trimble Connect, Trimble ProjectSight, Microsoft SharePoint, MCP, Procore (RFI auto-create), Slack notifications, and Microsoft Teams notifications.
MarkedUp checks that the sheet index matches the sheet numbers, callouts point to real details, door tags match the schedule and plan, keynotes match the plan and legend, and MEP equipment and panels match the plan. Run the check before the set becomes someone else’s problem.
