PRECONSTRUCTION SOFTWARE · BY VELLARIN
From the invitation to bid to the proposal you send.
BidStream covers all seven stages of a bid: finding the solicitation, loading the plan set, flagging scope at risk, taking off quantities, estimating, proposing and coordinating subcontractors. AI proposes at every step; the estimator approves.
AI-assisted. Estimator-controlled. Traceable to the plan.
THE FULL WALKTHROUGH
The bid starts long before the takeoff.
The seven stages every bid moves through, and where BidStream sits in each one.

STAGE BY STAGE
What BidStream does today — no roadmap promises.
1 · Opportunity
- Bid radar on SAM.gov’s official public API — no scraping
- Every new notice is tagged by trade and scored against your company profile
- Runs daily on its own, or on demand whenever you want to search
- What you have already seen is never reprocessed: the list grows, the noise does not
2 · Project intake
- Several PDFs at once, with a type and a label per file
- The set splits in batches and resumes — 90+ sheet sets without losing progress
- Title block reading: sheet number and title for every page
- Drawings, specs and other documents are handled differently — a spec carries no scale
3 · Scope and risk
- Reads notes, cover sheet and specs BEFORE any takeoff
- Proposes what the bid must protect against: exclusions, allowances, RFIs and scope to sub out
- Each finding routes to its exit — the exclusion to the proposal, the sub to the subcontracts tab
- Uncertain scope is flagged for human review
4 · Takeoff
- Assisted detection on the drawing geometry: proposes copies of a repeated symbol for your review
- Vision pass for scanned drawings
- Length, area, volume and angle on a scale confirmed per sheet
- 3D view: markups rise in height above the plan
- Review card: approve or reject every proposed detection
5 · Estimate
- Approved quantities feed the line-item register
- Adjust a measurement and the line item recalculates itself
- Estimated cost shown before every AI run — no surprises
6 · Proposal
- Proposal generated from the estimate, carrying your branding
- Shareable link with sell prices, without exposing costs or margins
- Export to PDF with real vector annotations — opens in any reader
- Exclusions caught back in the scope stage land in the document on their own
7 · Post-bid
- Trade packages and quote requests out to subcontractors
- Link-based portal: the sub quotes or declines without creating an account
- Schedule: AI proposes phases with duration and overlap; you edit all of it. Not a contractual construction schedule
- Revisions: new sheets link to their previous version and compare side by side
Across the project
- A copilot that answers from your project data — never with invented numbers
- It only proposes actions: it shows confirm or cancel, and never writes on its own
- AI spend caps per organization, with usage in plain view
- Real-time collaboration: your team works on the same project
- All in the browser: nothing to install
For specialty contractors with one to five estimators, and the preconstruction teams that bid alongside them.
