For licensed engineers & PE reviewers

A first pass you can actually review.

Contractors across every CSI division bring you BidCertain analyses instead of a raw bid package — so what reaches your desk is already cited, structured, and triaged: system selection, loads, sizing, assumptions, and draft RFIs, every claim traceable to a plan/spec page. Your job stays yours — review, correct, seal. We make the first draft worth your review, whatever the trade.

What reaches your desk

A first draft worth your review.

Whatever the trade, the analysis is cited, structured, and triaged before it ever gets to you — so your check is faster, not outsourced.

Every claim cited to source, across trades. Whether the contractor is bidding structural concrete (ACI 318/301, mix f'c, FF/FL), structural steel (AISC 360/303, connection-design split), fire suppression (NFPA 13 hazard class + fire-pump/water-supply), or earthwork (geotech compaction %, rock/undercut trigger) — each analysis cites the governing code and the sheet/spec section it came from, so your check is a fast look-up, not a re-derivation.

Structured for the specific review that trade needs. A concrete reviewer gets formwork-SFCA/rebar-schedule/FF-FL structure; a structural-steel reviewer gets the AISC 303 scope split + NDT/inspection lines; a sprinkler reviewer gets the hazard-class + fire-pump/water-supply question. The analysis is trade-aware, so the review is grounded in the right codes from the start.

The risky assumptions surfaced, not buried. Loads vs. ground, mix design f'c, coating/fireproofing scope, water supply vs. fire pump, slab moisture (ASTM F2170), below-grade water table — the items that change the design are flagged as assumptions for you to verify, with the source attached. Nothing is presented as final engineering.

Auto-drafted RFIs your contractor actually sends. The scope-gap and design-clarification questions (from every trade's common-RFI set) come out of the cited gaps, so the contractor shows up to you with the right questions already framed — and you answer them against the source.

Built around your review

The engineer stays the final authority.

Every claim cited to source

Each recommendation traces to the plan sheet or spec section it came from, across every CSI division — so your check is a fast look-up, not a re-derivation.

Structured for PE review

System selection, loads, sizing, and assumptions laid out in the order a licensed reviewer works through them — trade-aware, grounded in the right codes from the start.

Risky assumptions surfaced

The items that change the design — loads vs. ground, mix f'c, coating scope, water supply, slab moisture — are flagged as assumptions to verify, never presented as final engineering.

Design-assist only

It never acts as the engineer of record and stamps nothing. Every output remains your professional responsibility to review and seal. You are the final authority.

“"I don't review another AI model's output; I need the contractor's drawings, loads, and geotech, not a summarizer."”
That's the right instinct — and the whole point. BidCertain is a design-assist tool for the CONTRACTOR: it doesn't stamp anything, never acts as engineer of record, and every output remains your professional responsibility to review and seal. What it changes is the shape of what reaches you: a cited, structured first pass you can check against the set in minutes, on whatever trade the contractor bids, instead of a raw, un-triaged package. It respects the engineered-design boundary that makes your review meaningful — and makes that review faster because the citations are the audit trail. The design-assist framing is not a compromise; it's what keeps the engineer the final authority.
