How it works
Upload Plans AI Generates Draft You Review & Win
A simple path from incoming documents to a bid package your team can stand behind.
01
Upload the bid package
Bring in plans, specs, addenda, photos, or CAD files. Or just speak your scope using voice-to-estimate.
02
AI generates draft estimate
BuildBid extracts quantities, matches unit costs, organizes by CSI division, and flags potential scope gaps.
03
You review & win
Verify quantities, adjust pricing, add markup, export to PDF/CSV, and submit with confidence.

Built by estimators
Review-first philosophy
BuildBid was built by people who've priced real work. We know AI can't replace estimator judgment — but it can handle the grunt work so you focus on what matters: scope gaps, pricing strategy, and winning work.
AI generates the first draft — you verify before it goes out
Confidence signals on every line item so you know what to double-check
Scope gap detection flags commonly missing items (permits, bonds, temp facilities)
Export controls: internal view vs. customer-facing proposal
How it works in practice
Upload a real plan set and get a structured draft in under an hour — organized by CSI division, with quantities, unit costs, and confidence signals on every line. You review, adjust, and approve before anything goes out.
The difference: Most estimating software makes you build from scratch. BuildBid starts with a draft you can review, adjust, and approve. That's how estimators actually work.

Why teams look at BuildBid
Faster estimating is only useful if the draft is easier to trust and easier to review.
Start from a draft instead of a blank sheet
Upload plan sets, specs, photos, or DWGs and generate a first-pass estimate your team can review and refine.
Catch conflicts before bid day
Surface spec contradictions, scope gaps, and review flags while the job is still being priced.
Share cleaner proposals faster
Move from internal estimate to customer-facing exports and share links without rebuilding the package manually.
Built for distinct workflows
Different teams need different reasons to care.
For general contractors
Tighten preconstruction handoffs
Use BuildBid to turn incoming bid packages into reviewable drafts, package trade scope, and share polished owner-facing outputs faster.

Why estimators trust BuildBid
We don't expect you to blindly trust AI. That's why every single number we extract is linked directly to the source document, letting you verify 10x faster.
Provenance UI Demo (90s)

Click-to-Verify Provenance
Click any line item to instantly jump to the exact page and highlighted bounding box in the original plans. No more hunting for the source of a quantity.
Honest Confidence Badges
If the AI is unsure or can't price an item, we don't hide it behind a generic $0.00. We prominently flag it with a red "NEEDS PRICING" badge for human review.
Batch Verification Workflow
Speed through the review process by sorting items by trade, confidence score, or cost, allowing senior estimators to approve packages in minutes.
Trust and transparency
Say less. Document more.
The fastest way to lose trust in estimating software is to overclaim. BuildBid should be treated as a drafting and review tool, not a replacement for estimator judgment.
Security

Privacy
Read what data is collected, why it is used, and where manual review still applies.
Terms

FAQ
Common questions before you commit time
Is BuildBid fully autonomous?+
No. BuildBid is best used as a review-first estimating assistant. It generates a draft quickly, but a contractor or estimator should verify quantities, scope, exclusions, and pricing before submitting a bid.
What can I upload?+
The current product supports PDFs, DWG/DXF files, and common image formats, including multi-file uploads for plan sets and supporting documents.
Who is it built for?+
BuildBid is aimed at general contractors, subcontractors, and preconstruction teams that want to speed up first-pass estimating and produce cleaner bid packages.
How do you handle documents and customer data?+
BuildBid stores files and estimate records so the product can process uploads, maintain account history, and support exports or sharing. The privacy and security pages explain the current handling model in plain language.
