AI for construction lawyers: owner, contractor and subcontract review in Word

Construction contracts are long, heavily negotiated and full of risk-shifting language: owner-contractor agreements, general conditions, subcontracts, design agreements, lien waivers and bonds. Many start from AIA or ConsensusDocs forms and then grow pages of riders. An AI assistant in Word can do the first pass and the markup, so you spend your time on the clauses that decide who pays when the job goes wrong.

Where AI helps in a construction practice

• First-pass review of riders and supplementary conditions. Flag one-sided terms and missing standard protections before you read line by line.
• Flow-down checks. Compare what the prime contract demands with what the subcontract passes down, clause by clause.
• Clean defined terms. "Substantial Completion", "Contract Documents" and "Change Order" carry real money. Rule-based checks find terms used without a definition and cross-references that point nowhere.
• Drafting. LexDraft has a service agreement drafting workflow and a construction clause library, so you can start a subcontract or consulting agreement in Word and edit from there.

Prime contract and subcontract: what to check

• Contract documents and precedence. Which documents control when the drawings, specifications and riders conflict.
• Price and payment. Lump sum, cost-plus or a guaranteed maximum price; payment application timing; retainage and when it is released.
• Pay-when-paid or pay-if-paid. Whether owner payment is a timing mechanism or a true condition precedent (see the state rules below).
• Changes. Who can order a change, how it is priced, and the notice deadline for claims. Missed notice is one of the most common ways a valid claim is lost.
• Schedule and delay. Liquidated damages, excusable delay, no-damage-for-delay clauses and the waiver of consequential damages. The AIA A201 general conditions include a mutual waiver of consequential damages; check whether a rider removes it.
• Differing site conditions and who bears the risk of the design. Under United States v. Spearin (1918), an owner that supplies the plans and specifications impliedly warrants that they are adequate.
• Indemnity and insurance. Scope of the indemnity, additional insured requirements and waiver of subrogation.
• Warranty, termination for convenience and dispute resolution, including whether arbitration binds the subcontractor in a joint proceeding.

State rules that change the answer

• Anti-indemnity statutes. Most states limit construction indemnities. New York General Obligations Law 5-322.1 voids a clause that indemnifies a party for its own negligence. California Civil Code 2782 voids indemnity for the indemnitee's sole negligence or wilful misconduct. Texas Insurance Code Chapter 151 restricts broad-form indemnity and the matching additional insured coverage.
• Pay-if-paid. New York's highest court held pay-if-paid clauses unenforceable in West-Fair Electric Contractors v. Aetna (1995), and the California Supreme Court did the same in Wm. R. Clarke Corp. v. Safeco (1997). Other states enforce them if the language is clear.
• No-damage-for-delay. Washington voids these clauses where the delay is caused by the party relying on them (RCW 4.24.360). New York enforces them subject to exceptions set out in Corinno Civetta Construction v. City of New York (1986).
• Lien waivers. California requires the statutory conditional and unconditional waiver forms in Civil Code 8132 to 8138, and several other states, including Texas, now prescribe their own forms.
• Federal projects. The Miller Act (40 U.S.C. 3131 to 3134) requires payment and performance bonds on most federal construction contracts above a dollar threshold, and gives unpaid subcontractors and suppliers a claim on the payment bond.

Select the project's state in LexDraft before you review, so state-specific red flags are checked against the right jurisdiction.

A workflow in Word with LexDraft

1. Open the contract or subcontract in Word and open LexDraft in the side panel.
2. Select the project state and run the review. Findings come back graded Critical, High, Medium or Low, with missing standard terms flagged.
3. Run the defined-term and cross-reference checks. They are rule-based and finish almost instantly.
4. Accept the redlines you agree with as native Word tracked changes, reject the rest and add your own.
5. Read the payment, changes, delay and indemnity sections together before you send the turn.

What LexDraft does not do

LexDraft does not read drawings or schedules, calculate lien deadlines, track bonds or give legal advice. It has no dedicated construction playbook, and it does not know the project's history unless you tell it. AI review can miss issues or be wrong, so read the marked-up document yourself before it goes out.

Using AI ethically in this practice

ABA Formal Opinion 512 (July 2024) and many state bars say the same four things: understand the tool, protect client confidences, check every output, and bill fairly for AI-assisted work. Our state-by-state guide to AI ethics for solo lawyers summarises the guidance in 20 states and D.C.
