AI for construction that reads the subcontracts, submittals and pay apps your team checks by hand

We build AI agents for general and specialty contractors, inside the project and accounting systems you already run. They review contracts, level bids, draft RFIs and check pay applications, and your project manager approves anything that commits money or changes a contract.

How AI is used in construction, from bid day to closeout

Start with documents that arrive every week, follow a format your team already enforces, and get checked by a person before they cost money. These six workflows meet all three.

Contracts

Subcontract and contract review

The agent reads the base agreement, general conditions and exhibits together, compares each clause with your standard positions, and sends the deviations to your contract administrator with the page reference.

How the agent holds your standard terms
Preconstruction

Bid leveling and scope gaps

Subcontractor bids arrive in different formats. The agent pulls each into one leveling sheet by scope item, marks exclusions and missing scope, and leaves the award to your estimator. It works from your takeoff software's quantities and does not measure drawings.

RFIs and submittals

RFI drafts and submittal checks

The agent turns a field question into an RFI with the drawing and spec section attached, checks each submittal against the spec section it answers, and routes both to the reviewer with what it found.

Field

Daily reports

Superintendents send notes, photos and voice memos from site. The agent writes them into your daily report format, with manpower, weather, deliveries and delays filled in, for the superintendent to confirm before it files.

Compliance

Insurance and safety paperwork

The agent reads each certificate of insurance against the limits in the subcontract, tracks expiry dates, and chases missing safety documents, such as toolbox talk sign-ins, before a subcontractor mobilizes.

How every run is logged
AP

AP and pay applications

The agent checks each pay application against the schedule of values and the field record, recomputes retainage, confirms the lien waiver and insurance are on file, and queues it for your project manager.

Where a project team's week goes

14 hrs

a week per person spent looking for project data, resolving conflicts and dealing with rework

Source: FMI and PlanGrid, Construction Disconnected (2018), a survey of 600 construction professionals, 49% of them general contractors and 36% specialty trades.

Two industry reports put numbers on the paperwork. Each figure maps to the agent that takes it on.

5.5 hours a week looking for project data

Revised drawings, material cut sheets and the current spec. The RFI and submittal agents attach the document they reference, so the reviewer opens one record instead of searching for it.

65 hours a month on payment administration

Rabbet counts this for general contractors. The pay application agent does the line-by-line checking and leaves the approval to your project manager.

Nearly 4 hours a week assessing rework

Daily reports written the same day, from the superintendent's own notes, give your team the record to trace a mistake to its cause and cost.

Start with the documents that repeat

Contracts, pay apps and daily reports already follow rules your team enforces. Those rules become the agent's instructions, and the AI Audit ranks which workflow to build first.

AI construction contract review, clause by clause

A subcontract package is several documents that modify each other. The agent reads them as one, against the positions your contract team already holds.

The whole package, read together

When Division 01 or a supplementary condition changes a payment term in the base agreement, the agent links the two and reviews the clause as amended.

Your positions, written down once

Your acceptable indemnity scope, notice windows, retainage release and insurance limits sit in a context layer the agent reads on every review, so each contract is checked against the same standard.

Every flag cites its page

Deviations reach your contract administrator with the clause quoted and the page number, so your administrator checks the agent against the contract itself.

A person decides every term

The agent flags and summarizes. Your contract administrator or counsel accepts, negotiates or rejects, and the run log records who did.

Pay applications checked line by line before anyone signs

A pay application touches the schedule of values, the field record, retainage, lien waivers and insurance. The agent checks all five and hands your project manager one decision with the exceptions on top.

Who approves, and where your project data stays

Every workflow we build carries three controls, agreed with you during scoping.

Approval gates

A person signs off on money and contracts

Pay applications, change orders and contract deviations wait for the person who owns them. The agent cannot approve a payment, accept a clause or send a document to an owner on its own.

See AI governance
Second check

A second agent checks the first

Before a flag or a figure reaches your team, a second agent re-reads it against the source document and sends back anything it cannot confirm before your team sees it.

Your cloud

Built in your environment, every run logged

We deploy on self-hosted n8n in your cloud, behind your own sign-in, so contracts, drawings and cost data stay with you. Every run records what it read, what it changed and who approved it.

What contractors ask about AI

Ask us something else

How is AI used in construction?

The workflows we build sit on the office side of a project: reviewing subcontracts, leveling bids, drafting RFIs, checking submittals against the spec, writing daily reports from field notes, tracking insurance certificates and checking pay applications. Each is a document your team reads against rules it already follows, which is work an agent can do and a person can check.

Can AI review construction submittals?

It can do the first pass. The agent reads the product data or shop drawing, compares it with the requirements in the spec section it answers, and lists what matches, what is missing and what differs. Your reviewer, architect or engineer still approves or rejects the submittal, with the agent's list attached.

Can AI do construction takeoffs?

Dedicated takeoff software measures quantities from plan sets, and a general language model reading a PDF is not a reliable substitute. We build around the takeoff your estimators already trust: the agent takes its quantities into bid leveling, checks each subcontractor bid against them and marks the scope gaps.

Which AI is best for construction?

It depends on the job. Packaged software fits a single task inside one system, such as measuring drawings or scheduling. A custom build fits when the work spans systems, such as a pay application that touches your project management platform, the daily reports and your ERP. The AI Audit tells you which of your workflows need which.

How do you automate construction bidding with AI?

Start with leveling. The agent reads each subcontractor bid as it arrives, maps it to your scope items, lists exclusions and qualifications, and compares the totals against your takeoff. Your estimator reviews one leveled sheet and decides the award.

Will AI replace construction project managers?

No. The agents take on reading, checking and drafting, and the decisions stay with your project managers, superintendents and estimators. Every workflow we build sends anything that commits money or changes a contract to the person who owns it.

Which systems can you connect to, and does our data leave our environment?

We connect through whatever your systems expose: an API on your project management platform, an export from your accounting system, a shared drive, or the inbox where documents arrive. The workflow runs on self-hosted n8n in your cloud, behind your own sign-in, so your contracts and cost data stay with you. The architecture guide shows how agents connect to an ERP.

What does it cost, and how long does it take?

Every build is priced in a written scope before you sign. If you start with the AI Audit, it costs $10,000 to $100,000 depending on scope, takes 4 to 8 weeks, and its fee is credited toward your first build. An AI pilot on one workflow costs $35,000 to $75,000 and takes 2 to 6 weeks, and its fee is credited toward the build too.
