AI for General Contractors in 2026: Bids, RFIs and the Paper Trail

AI can now measure a takeoff from drawings, draft a submittal log from the spec book, pre-fill an RFI, turn site photos and voice notes into a daily log and flag risky clauses in a subcontract. It can't run your job, price your risk, sign a change order or answer for the work. Let it draft the paper, and keep a person on every page that leaves the trailer.

A general contractor's admin is unusual because almost none of it is yours alone. It moves between the owner, the architect, a dozen subs and the building department, and every document has a deadline and a second reader. That's why AI helps most here when it sits where your project records already live. Below is the work by phase of a job, the tools that handle each part, and the places where a person still has to decide.

Why a GC's paperwork piles up

General contracting is coordination work, and coordination produces paper. The Bureau of Labor Statistics' construction managers page lists the core of the job: preparing cost estimates and schedules, interpreting contracts, selecting subcontractors and coordinating their activities, reporting progress and budget to clients, and responding to delays and emergencies. It also notes managers may have to be on call around the clock for project emergencies, and that some states require a license.

O*NET's task list for construction managers fills in the desk side: preparing contracts and negotiating revisions with subcontractors and suppliers, applying for permits, submitting budget estimates and progress reports, and changing plans in response to delays or weather. On an actual project, that turns into a steady stream of documents:

• Bid packages and takeoffs: quantities off the drawings, scopes split by trade, sub bids to compare line by line.
• Contracts and subcontracts: flow-down clauses, notice periods, insurance and indemnity language.
• RFIs: questions to the design team when the drawings disagree with the site or with each other.
• Submittals: the log built from the spec book, then shop drawings and product data chased from each sub.
• Change orders: pricing extra work, getting it signed, and tracking what's approved versus pending.
• Daily logs: crews on site, weather, deliveries, inspections and delays, written up before you leave.
• Owner updates and pay applications: progress, photos, schedule changes and what's coming next.
• Permits and inspections: applications, inspection requests and the corrections list.

What AI handles at each stage of a job

For a general contractor, AI is most useful inside construction software that already holds the drawings, specs and project records: takeoff tools for estimating, and project management platforms such as Procore and Autodesk's construction software for RFIs, submittals and logs. General chat assistants help with one-off writing, and contract review tools read the fine print.

Takeoffs and bids

Takeoff is the estimating task AI tools go after most directly, because measuring sheet after sheet is slow, repetitive work. Togal.AI says it detects and measures items directly from drawings, compares two drawing sets and quantifies what changed, and lets you ask questions about the plans through Togal.CHAT. Togal claims up to 98% accuracy on floor plans; that's the vendor's own figure. Its pricing page lists a Growth plan at $299 per user per month, billed yearly, and custom pricing for teams of four or more.

The comparison tool matters on a bid more than the first takeoff does. When addendum 3 lands two days before bids are due, knowing exactly which rooms and quantities changed tells you which subs to call back for revised numbers. Spot-check the measured areas against the plans anyway, especially on sheets with unusual scales or hand markups.

Contracts and flow-down language

Contract review is a narrow, high-stakes job that suits purpose-built tools better than a general chatbot. Document Crunch describes AI that reads construction documents and gives answers cited to the source, checks for inconsistencies between the contract and the specs before you write RFIs, and drafts submittals, notices and RFIs for review. Pricing isn't published; it offers a free trial and a demo. Procore's Contract Review Agent compares contracts and drawings against internal benchmarks and flags conflicts.

Use these to find the clause. Deciding what to do about it stays with you. A tool can point out that the owner contract gives you 7 days' notice for a claim while your subcontract gives the sub 10. Fixing that gap is a business decision, and sometimes a lawyer's.

RFIs, submittals and the spec book

On a commercial job, the spec book is a good fit for AI, because building the submittal register by hand means reading every section. Autodesk's AutoSpecs page says it drafts submittal logs from specifications, sorting action submittals, product data, closeout and QA/QC items, compares spec versions to flag changed requirements, and suggests submittals that may be missing based on past projects. The log can then be published to Forma Build; Autodesk notes that Autodesk Construction Cloud is now part of Autodesk Forma.

Procore's AI page lists agents for the same stretch of the job: an RFI Agent that drafts pre-populated RFIs from drawings and project data, a Submittal Review Agent that checks submittals against specs and contracts, and a Deep Search Agent that answers questions across specs, drawings, RFIs and submittals with citations. Procore says agents need human sign-off before acting and that its AI respects existing project permissions. Procore doesn't charge per user; its pricing page says the annual fee depends on the products and your annual construction volume.

Daily logs and owner updates

The daily log is easy to skip on a hard day, and it's the record you'll go looking for if a delay is ever argued over. Procore's Daily Log Agent builds the log from field photos, emails, video and voice input, so a superintendent can talk through the day on the drive home. Read the draft before it's saved: a log that says the inspection passed when it was a partial pass is worse than a short log.

Owner updates come from the same raw material. A chat assistant can turn a week of logs and the three-week lookahead into a plain-language note for an owner who doesn't read Gantt charts. Strip out anything you haven't confirmed yet, like a delivery date the supplier only promised verbally.

Where AI stops on a construction project

AI reads documents; it doesn't walk the site, carry the license or hold the contract. Every tool above produces a draft or a flag, and the decisions in construction are the ones with money, schedule and liability attached.

• Change orders need signatures. On residential remodels in California, for example, Business and Professions Code section 7159 requires a home improvement contract and its changes to be in writing and signed before the work they cover begins. Commercial contracts set their own change-order terms. Either way, AI can price and word a change order; only the parties can agree to it.
• The estimate is your risk. A takeoff gives quantities. It doesn't know the site has no laydown area, the sub who's always late or the owner who will fight every extra.
• RFI answers come from the design team. AI can draft the question and find the conflicting sheets. Don't let it suggest an answer and build to that.
• Licensing and code compliance stay with people. Some states license construction managers, per the BLS, and code questions belong to the local building department.
• Check where project data goes. Drawings, bid numbers and owner contracts are confidential. Procore says customer data isn't used to train third-party models; look for the same statement before you paste a bid tab into any other tool.

Where Merlin fits for general contractors

Merlin helps with the email traffic that wraps around a project: the architect's response to an RFI, the sub who sent revised numbers at 6 a.m., the owner asking whether the inspection moved. It runs on a Mac, reads the inbox and calendar you already keep in Google, keeps track of the people you deal with and what you've told them, and drafts replies you check and approve.

Merlin doesn't do takeoffs, write estimates, manage RFIs or submittals, keep daily logs, answer phone calls or send invoices. Those belong in the construction tools above. Merlin covers the inbox and calendar beside them.

• Who's still waiting. The People panel shows contacts whose direct emails are still unanswered, such as the sub asking for a decision on an alternate. It reads email only, so a question asked on a site walk won't show up there.
• Promises in one list. The To-do panel collects follow-ups Merlin finds in your mail, like a promised revised schedule, next to tasks you type in yourself, such as "send the owner the updated lookahead Thursday".
• Replies on a card. Tell Merlin to answer the architect and the draft appears on a card to edit and approve. Nothing requested that way goes out before you press approve.
• Owner and architect meetings. The built-in Meeting Brief routine prepares you shortly ahead of a call, and Merlin's Meetings tab records an owner-architect-contractor (OAC) meeting on Zoom and keeps notes. A transcript showing who said what comes with a paid plan, and you should tell everyone the meeting is being recorded.
• Routines for repeat mail. A routine can start when new mail matches a sender or subject you set, so every bid-day email from one owner's procurement team gets summarized for you. Routines run unattended once they're on, so test one and read what it would have done before you let it send anything.

How to start using AI on your jobs this week

Pick the document that eats the most office hours on your current projects, and try AI on it for one job with someone checking every draft.

1. Find the bottleneck. For most GCs it's either the submittal register at buyout or the daily log at the end of the day. Pick one.
2. Check your platform first. If you run Procore or Autodesk's construction software, look at which AI features your plan already includes before buying another tool.
3. Run the next bid through a takeoff trial. Measure one bid both ways and compare the quantities before trusting either.
4. Assign a reviewer to every AI draft. The PM signs off on RFIs and submittals, the superintendent on the daily log, and the owner of the business on anything with a price.
