Built to be reviewed,
not just generated.

Other AI estimators hand back a wall of line items and expect you to trust it. BuildBid returns a draft your estimator can actually audit — with the receipts attached.

  • 01 · PROVENANCE

    Source-linked quantities

    Every line item points back to the drawing or spec source, so a reviewer can click a number and land on the page it came from.

  • 02 · REVIEW

    Review flags

    Low-confidence items, missing scope, and conflicts surface first — not buried in a 400-row spreadsheet.

  • 03 · EXPORT

    Export-ready proposal

    CSV, PDF, XLSX, and a customer-facing share link — one click once the review is clean.

the project produced.

BuildBid parses the actual artifacts from the field — plan sets, spec books, addenda, sketches, site photos — and puts them into one pipeline. No data re-entry. No rebuild from scratch.

  • PDF plan sets
  • DWG / DXF
  • Common image formats (PNG, JPG)
  • Multi-file submissions
  • Community pricing signals
  • Tenant-isolated storage; every file scoped to your org
  • Source-linked line items — every quantity traces back to the drawing
  • Feedback loop: every correction trains the pipeline

02METHOD4-STAGE VISION PIPELINE

The estimator verifies.
The network does the grunt work.

Every stage produces a structured artifact. Every correction becomes training data. The pipeline sharpens with every estimate you ship, not on a fixed release cycle.

STAGE 01VISION

Extract vector geometry, text, and deterministic measurements from the source PDF and vector formats.

STAGE 02SEMANTICS

Classify assemblies, rooms, and trade scopes — neural networks do what neural networks are good at.

STAGE 03MEASUREMENT

Compute quantities, areas, volumes. Zero-shot segmentation assists the verifier, never replaces it.

STAGE 04QA

Flag conflicts, confidence outliers, and scope gaps. Present only what the estimator needs to review.

03OUTPUTESTIMATE · EST-2026-0412-A

The draft lands as a real estimate.

Line items by CSI division. Quantities with units. Unit costs pulled from your priced library. Confidence and scope-gap flags attached in place. Export to CSV or PDF. Send to QuickBooks or Procore.
