In a construction business, the job site always comes first. Everything else happens afterwards: the quote requested on Monday, next week's schedule, the certificates to request from a subcontractor, the minutes of the site meeting, the end-of-month progress claim. None of these tasks is complicated, but there are a lot of them, and forgetting one is expensive: a quote sent too late, a subcontractor who is no longer compliant, a progress invoice billed a month late.
AI agents are well suited to this repetitive office work. This article details concrete uses for a site manager, the owner of a finishing-trades SME or a general contractor, with briefs ready to adapt.
What an AI agent can do in a construction company#
An AI agent carries out a specific task by connecting to your tools: email, calendar, spreadsheet, Google Drive, invoicing software, WhatsApp. It does not replace your estimating or management software if you have one; it links the information you already have with the people who need it.
The tasks that suit it best share three traits:
- they come back often (every week, every job, every month);
- they start from information already written down somewhere (plans, notes, spreadsheets, emails);
- their result is quick to check (a quote, a schedule, a list of missing documents).
Quotes and take-offs: from site survey to PDF#
The quote is the first serious contact with a client, and often the one that drags the most. Between the visit and sending it, you have to go back over the measurements, break them down by trade package, apply your prices, write the item descriptions and add your terms.
An estimating agent starts from what you drop into a folder (plans, measurements, photos, visit notes) and from your price list kept in a spreadsheet. It produces the take-off by package, prices it, writes a PDF quote on your letterhead and clearly lists the assumptions it made. That is the Construction quotes and take-offs template.
For every job folder added to "Quotes to do" in my Google Drive (plans, photos, visit notes), produce the take-off by package, price it using my price list (the "Prices 2026" tab in my Google Sheet) and write a PDF quote on my letterhead. At the end, list every assumption (assumed heights, condition of the substrate, access) and flag the items you could not price because they are missing from the price list. Never fill in a price yourself.
The last sentence matters: an agent must not invent a price that is not in your price list. It flags the gap, you fill it in. Once the quote is sent, the Quote follow-up template can politely chase quotes that have had no reply.
Limits to keep in mind#
A take-off based on photos or an incomplete plan remains an estimate. The agent saves you the formatting and calculation time, but a professional review is still needed, especially on the quantities that drive the price.
Site planning: every crew knows where it is going#
The schedule often lives in the site manager's head or in a spreadsheet only they understand. On Friday afternoon, every crew and every subcontractor needs to be told: where, when, with what equipment.
A planning agent reads your jobs spreadsheet, spots overlaps (the same crew on two sites on the same day) and delays, then sends everyone their schedule for the following week, by email or WhatsApp, with addresses and planned equipment. The Shared site schedule template is designed for this.
Every Friday at 2 pm, read the "Schedule" tab of my Google Sheet. For each crew and each subcontractor, send their schedule for next week on WhatsApp: day, site address, arrival time, equipment to bring. If a crew is booked on two sites on the same day, or an active site has nobody assigned, warn me before sending anything.
The agent can also cross-check the schedule with the weather forecast for the coming days to flag sensitive tasks (roofing, rendering, concrete pours): that is the Site weather template.
Subcontractors: certificates kept up to date without thinking about it#
In France, when you hire a subcontractor for a contract worth at least €5,000 excluding VAT, you must check that they are compliant, in particular by obtaining their URSSAF vigilance certificate (attestation de vigilance) when the contract is signed and then every six months until the work is finished. Depending on the case, you also need a recent company registration extract (Kbis), the list of foreign employees requiring a work permit and, in construction, proof of ten-year liability insurance (assurance décennale). Check with your adviser which obligations apply to your situation.
Tracking these documents is typically the kind of task that is forgotten until an inspection. A dedicated agent keeps a table per subcontractor, spots documents about to expire, requests them by email, files the ones it receives in a folder per company and alerts you if a subcontractor is no longer compliant. That is the Subcontractor certificates template.
| Document | What the agent does |
|---|---|
| URSSAF vigilance certificate | Calculates the next six-month deadline and requests the new one before expiry |
| Company registration extract (Kbis) | Requests a recent version according to the rule you set |
| Ten-year liability insurance | Checks the stated validity date and requests the renewal |
| List of foreign employees | Requests the document when it is due |
The agent checks that documents are present and dated correctly; the authenticity of a certificate is verified on the official services provided for that purpose. You can ask the agent to remind you to run that check.
Site reports and progress claims#
Two other tasks come back every week and every month:
- Site meeting minutes. You dictate your notes or take a few photos; the agent turns them into a PDF report by package (progress, snags, decisions, actions with owner and due date) and sends it to everyone involved. Template: Site meeting reports.
- Progress claims. At month end, the agent takes the signed quote and the progress per package, calculates the claim taking into account the retention set in the contract, and prepares the progress invoice in your software. Template: Progress claims.
For supplies, the Materials orders template prepares orders based on each site's needs.
Getting agents to work together#
Agents on the same account can hand work over to each other. A typical construction chain: one agent prices the quote, a second schedules the job as soon as the quote is accepted, a third prepares progress claims as the work advances. That is the Quotes, site schedule and progress claims chain template. Information flows through a shared table, and each agent only handles the new rows. You can watch the agents at work on the workflow map in your dashboard.
Agents also remember what you teach them: your terms and conditions, how you word your item descriptions, the names of your crew leaders. You can give them context files, such as your price list or a report template.
A typical week with three agents#
To make this concrete, picture a finishing-trades company of about fifteen people, with an owner, an assistant and two crew leaders.
- Monday morning, the subcontractor agent sends its weekly update: two vigilance certificates expire this month and the requests have already gone out; a drywall contractor still has not sent proof of ten-year insurance, and the owner is warned before booking them on a site.
- Tuesday, the owner comes back from a client visit. He drops his photos and notes into the "Quotes to do" folder. By late morning, the assistant finds a PDF quote ready to review, with three assumptions listed and one item flagged as having no price. She fills it in, and the quote goes out the same day.
- Wednesday, after the site meeting, the crew leader dictates five minutes of notes. The report by package is sent to the architect and the other trades that afternoon.
- Friday at 2 pm, the planning agent detects that a crew is booked on two sites the following Tuesday. It warns the owner before sending anything; once the conflict is resolved, each crew gets its schedule on WhatsApp.
Nothing spectacular in this scenario, and that is the point: every task already existed, it simply gets done on time, without eating into the evening.
Setting up your first agent#
- Start where it hurts most. For many companies, that means late quotes or subcontractor certificates.
- Tidy up the source. A clean spreadsheet with one tab per topic (prices, jobs, subcontractors) beats underused software.
- Describe the task in the chat or on WhatsApp, or pick a template from the construction library.
- Answer the architect's questions about frequency, recipients and rules.
- Connect your tools in one click.
- Approve the sample and the monthly price announced, then launch.
An agent costs from €3/month, most between €9 and €49/month depending on complexity. The Pro plan at €29/month includes five agents priced up to €9. Details on the pricing page.
What remains your job#
The agent does not replace the technical visit, a site manager's judgement on a tight schedule, or the conversation with an unhappy client. It takes care of what keeps you away from the site: formatting, notifying, requesting, chasing, filing. For smaller trade businesses, the article AI agents for tradespeople covers uses around service requests, and the construction use cases page gathers more examples.
