AI Contract Review for Trade Subcontractors: What It Should Flag Before You Sign

The subcontract arrives on a Thursday afternoon. The GC wants it signed by Monday. It is the base agreement, a stack of exhibits, an insurance schedule, and a paragraph that says the sub is bound by the prime contract, which nobody sent you. The owner reads what he can after the crews are home, skims the rest, and signs, because the job is worth having and the deadline is real.

That is the moment AI contract review is built for. A lot of what gets sold under that name is built for legal departments. For a trade sub, the useful version is smaller and more specific: read the whole agreement, every exhibit, and put the handful of clauses that carry your money and your risk in front of you before you sign.

Here is what that should look like, what it should flag, and where a person still has to decide.

What the tool should do, in plain terms

You upload the PDF. All of it, exhibits included. The tool reads the full text, checks it against the list of terms that matter to a subcontractor, and hands back two things:

1. A plain-English summary. What this agreement says, in the words you would use to explain it to your foreman. Where it is ordinary, it says so briefly. Where it departs from what you usually see, it says where and how.
2. A short issue list. The specific clauses worth a second look, each with the page and section it came from, so you or your attorney can go straight to it.

If the tool you are looking at cannot point to the page, it is asking you to trust it. A good one makes checking it fast.

The clauses it should flag for a trade sub

A general-purpose contract tool reads for whatever a lawyer at a big company cares about. A sub cares about a shorter list, and the tool should know it:

• Payment timing. When you get paid, and what has to happen first. Pay-when-paid and pay-if-paid language belongs at the top of the list, because the difference between them decides whether you get paid at all when the owner does not pay the GC.
• Retainage. How much is held back, when it stops being held, and what triggers its release at the end of the job.
• Indemnification. Whose mistakes you are agreeing to cover. Broad-form language that has you covering the GC's own negligence is the clause that most deserves your attorney's attention.
• Insurance and additional insured. What coverage you must carry, at what limits, and who must be named on it. Your agent needs this list before you sign, not after.
• Flow-down provisions. The paragraph that binds you to the prime contract. The tool should say plainly that you are agreeing to terms you have not seen, and you should ask for the prime contract.
• Change orders. How a change gets approved, in writing, by whom, and how many days you have to give notice. Miss the notice window and the extra work can go unpaid.
• Termination and default. What lets the GC end the agreement, on how much notice, and what you are owed if they do it for convenience.
• Liquidated damages. Whether the owner's delay penalties can be passed down to you, and on what terms.
• Schedule and notice. Every clock in the agreement, in one place: notice of delay, notice of claim, days to cure.

That last one matters more than it looks. Most of the damage in a subcontract comes from a deadline you did not know you had.

Where you still decide

The tool reads. You decide. That line should be easy to see in the output.

It cannot tell you whether a term is acceptable for this job with this GC. It does not know that you have done six jobs for them and they have always paid in thirty days, or that this is a new GC and the payment terms are the whole question. It cannot give you legal advice, and a tool that sounds like it is giving legal advice is a reason to be careful.

What it changes is where your attorney's time goes. Instead of paying for a full read of the whole document, you send the three or four flagged clauses and ask a specific question about each. The attorney reviews what matters, and the review fits inside a bid deadline.

What it looks like in practice

I built one of these. A full subcontract, exhibits included, read and summarized with its risky clauses flagged in about fifteen minutes, against two to three hours of a principal reading it by hand. The write-up is on the portfolio page, along with what it checks.

The time saving is the obvious part. The part owners notice later is consistency: every agreement gets read in full, the same way, instead of depending on how much of the evening was left.

Before you buy one

Three questions to ask, of any contract review tool or of whoever is selling it:

1. Does it read the exhibits? A tool that stops at the base agreement misses where insurance requirements and flow-down terms usually live.
2. Does every flag cite a page and section? If you cannot check it in a minute, you will stop checking it.
3. Where does the contract go? Your subcontracts carry your pricing and your customers. Ask where the document is stored, who can see it, and whether it is used to train anything.

If contract review is your bottleneck, a tool for it can be small and focused. If it is one of several places the office loses time, it may be the third thing to fix, after the ones that happen every day. Sorting that out is what the AI Audit is for: I map how a job moves through the shop, from the bid to the final invoice, and write down which handoffs to configure, which to connect, which to build, and which to leave alone.

If you want to talk through yours, book thirty minutes. No pitch. If it is not a fit, I'll tell you.
