Blueprints shouldn't cost you a day of estimating
Scaling rulers, printed plan sets, and spreadsheets slow every bid down — and one missed detail on page 14 can cost you the job.
Every plan set has a different scale, orientation, and revision. Measuring by hand across dozens of sheets eats hours estimators don't have.
Ottermap auto-detects scale from the title block and calibrates every sheet automatically.
A detail buried in a legend or a revision cloud on sheet 9 can throw off an entire bid — and by the time it's caught, the job is already priced.
Layered takeoffs flag every callout, legend item, and revision so nothing slips through.
Paving, concrete, fencing, and sitework crews often re-derive quantities from the same drawings independently, wasting time and creating inconsistent numbers.
One shared, editable takeoff per project keeps every trade working from the same numbers.
Multi-sheet, multi-phase projects and portfolio bids turn into a filing problem before they're even an estimating problem.
Bulk upload and organize hundreds of sheets across phases, revisions, and sites in one dashboard.
From PDF to priced takeoff in four steps
Upload your plans
Drop in PDF blueprints, architectural drawings, spec sheets, or legends — single sheet or full set.
Auto-calibrate scale
Ottermap reads the title block and scale bar to calibrate every sheet, no manual ruler work required.
Review AI-generated quantities
Areas, lines, and counts are detected automatically by layer and trade — edit, relabel, or add notes in a click.
Export and bid
Send branded, exportable takeoffs to your estimating software, CRM, or straight into a proposal.
Built for plan sets, not just parcels
Everything from Ottermap's aerial takeoff tools, purpose-built for blueprint and construction-document workflows.
Any plan format
Upload multi-page PDF plan sets, scanned drawings, or CAD exports — Ottermap handles them all in one project.
Automatic scale calibration
No manual ruler-setting. Ottermap detects scale bars and title-block data to calibrate every sheet automatically.
Layered, trade-specific takeoffs
Separate layers for paving, concrete, fencing, utilities, and sitework so every trade sees only what's relevant.
Revision tracking
See what changed between plan revisions so re-bids and change orders don't mean starting over.
Team collaboration
Multiple estimators can work the same plan set with role-based permissions, comments, and shared notes.
Export anywhere
Push finished takeoffs to PDF, Excel, your CRM, or estimating software — white-labeled with your branding.
