Compare construction AI
by the job it does.
Pick construction AI by the document it has to read, not by the brand. Bid packages, contracts, sub bids and plan sets are different jobs, and most tools start at only one of them. Below: what each job needs, how to test it in a demo, and where BAU AI fits.
Which kind of tool fits
which job?
Ten jobs, from finding the bid to closeout. For each: the document it starts from, what a tool must do, the question to ask in a demo and where BAU AI fits.
01
Find bids that fit
Starts fromPublic and private bid portals, plan rooms
A tool must
- Check sources every day against your trades, region, size and project types

Ask in the demo
“If a delivery slips, where does it show on the look-ahead?”
Kinds of tools that do this
Scheduling tools, project management platforms
Not what BAU AI does
- Sending invitations to bid and tracking bidders. That is bid management, done in your bid management platform. BAU AI works alongside it.
- Replacing your project management platform. Patrick, Dario, Lex, Fina, Colin and Pixer work on the same cited project record and connect to the platform you run the job in.
What does each approach
really deliver?
Analysis time, domain depth, sources, risk, bid leveling and data protection. The same six questions for manual review, a generic chat tool and BAU AI.
| Criterion | Manual review | Generic AIe.g. a general chat assistant |  Built for preconstruction |
|---|---|---|---|
| Analysis time | Not met: 2 to 3 days per 300-page bid package | Not met: Fast, but documents go in piece by piece | Met: Under 5 minutesillustrative, every finding with a page reference |
| Construction domain depth | Met: Present, depending on experience and the day | Not met: Knows AIA and ConsensusDocs only on the surfacecan cite clauses it cannot point to | Met: Built around AIA A201, ConsensusDocs, EJCDC, CSI MasterFormat and FAR 52 |
| Source citations | Met: Possible, but rarely documented systematically | Not met: No verifiable sources | Met: Every finding with clause and page |
| Risk detection | Not met: Clauses get missedLDs and indemnity often found after award | Not met: Finds the obvious, without contract context | Met: Risks before bid daycited to the supplementary conditions |
| Bid leveling and documentation | Not met: Spreadsheet leveling, error-prone, hard to audit | Not met: No scope structure, no audit trail | Met: Sub bids normalized to one scopeaward recommendation with the math shown |
| Data protection and hosting | Met: Documents stay in-house, but scattered across folders and inboxes | Not met: Depends on the plan and its settingscheck retention and training terms | Met: US data residency, no training on your dataSOC 2 Type II in progress |
| Project delivery after award | Not met: Spreadsheets, email and re-entry between toolsthe bid record stops at award | Not met: No project record to work fromeach chat starts from scratch | Met: Materials, site, punch, pay apps and schedule on the same recordPatrick, Dario, Lex, Fina, Colin and Pixer |
As of October 2026. Generic AI refers to standard chat products without construction-specific adaptation. Time figures are illustrative until US production data is available.
Why does generic AI
fall short on bid day?
General language models are impressive, but they are not built for US bid packages. For a Go/No-Go call on a seven-figure contract that is not enough: an analysis you cannot verify is no basis for a decision.
- PDFAddenda and bid forms read out of contextA chat tool sees the pages you paste, not the package as issued.
- A201Contract standards only on the surfaceIt does not know how a supplementary condition changes A201 §8.3 or §15.1.6.
- §Answers without a verifiable sourceNo page reference, no evidence, nothing for your counsel to check.
Manual review has the opposite problem: thorough and expert, but slow and poorly documented. Two to three days per package means many solicitations go unread.
ClaraBids and RFPsSame question, two answers · ExampleAre there liquidated damages in this bid package?
I can only see part of the package. Liquidated damages are common in construction contracts and are often a fixed amount per day of delay. Check the supplementary conditions.
Clara · BAU AIExampleYes. $5,000 per calendar day, with no cap. It runs from the Substantial Completion date in the agreement.
How do you test construction AI
in a demo?
Six checks that work on any vendor, including us. Each takes a few minutes and tells you more than a feature list.
- 01Bring your own packageUse a bid package, contract or set of sub bids from a job you already know, not the vendor's sample.
- 02Click five findingsOpen the cited page for each one. If a finding has no page, or the page does not say it, stop there.
- 03Ask about addendaIssue an addendum and see whether the findings update, or whether you start over.
- 04Name the base formAsk which forms it compares against: AIA A201, ConsensusDocs, EJCDC or your own standard.
- 05Get data terms in writingWhere are your documents stored, who can see them, and are they used to train models?
- 06Follow the findingAsk what happens after bid day. Does the finding reach the contract, buyout and takeoff, or does someone retype it?
How do I choose a construction AI tool?
Start with the document that costs you the most hours or the most risk: the owner's bid package, the contract, the sub bids or the plan set. Shortlist tools that start from that document, then test each one on your own files and check whether every finding cites its page.
Does BAU AI do bid management?
No. In the US, bid management means sending invitations to bid and tracking bidders, which your bid management platform does. BAU AI reads the bid package, the contract and the sub bids, and works alongside that platform.
Does BAU AI replace my project management platform?
No. BAU AI starts at the owner's documents and keeps one cited record from the first bid to closeout. After award, Patrick, Dario, Lex, Fina, Colin and Pixer cover the schedule, procurement, field reports, finance, communication and the pipeline on that record, and connect to platforms such as Procore, MS Project and Primavera, so your team can keep the tools it runs the job in.
Why doesn't this page name other vendors?
Products change faster than comparison pages, and the right tool depends on your documents. So we list each job, what a tool must do and how to test it, so you can check any vendor, including us, on your own files.
Bring a real bid package. Check the citations.
In 15 minutes we read your solicitation, contract or sub bids with you and show every finding next to its page.
