The verdict in three sentences
Site meeting minutes remain one of the most important documents in construction, and one of the most delayed: issued on average three days after the meeting, they leave trades working on vague decisions. A mobile app that records, transcribes and structures with AI the decisions, snags and actions by trade produces a reliable draft in minutes. For a 150-employee firm, the project costs EUR 6,000 to 15,000 excl. VAT and frees more than 2 hours per site manager per week.
Why manual minutes cost so much
A site manager runs 2 to 4 site meetings a week. He takes handwritten notes, then types them up in the evening or the next day in a Word template, going trade by trade (structure, electrical, plumbing, joinery). Late distribution creates disputes: an unrecorded snag or a wrongly noted date gets paid for in rework.
| Indicator | Manual writing | AI transcription and structuring |
|---|---|---|
| Writing time per meeting | 60 to 90 min | 15 to 20 min of review |
| Distribution delay | D+3 on average | Same day |
| Actions without owner or date | 20 to 30% | under 5% |
| Forgotten or poorly described snags | frequent | rare, timestamped |
| Finding a past decision | 15 min in emails | seconds by keyword |
| Weekly time per site manager | 3 h | 45 min |
How the solution works
The site manager starts recording on a smartphone or a tablet on the table. Audio goes to a transcription engine (Whisper, Azure Speech, Deepgram) that handles French, regional accents and site noise well with a decent conference mic. A language model (Claude, GPT, Mistral) then structures the text according to your minutes template: attendees, progress by trade, decisions, snags, actions with owner and deadline, follow-up points.
The draft lands in a web interface where the site manager corrects, approves, then sends a PDF to all parties. Actions feed a tracking board carried over from one meeting to the next, and history becomes searchable by project.
| Cost item | 2026 range | Detail |
|---|---|---|
| Scoping and minutes template | EUR 1,000 to 2,500 excl. VAT | Templates by meeting type, trades, vocabulary |
| Mobile recording app | EUR 2,000 to 5,000 excl. VAT | Offline, deferred upload without network |
| Transcription and structuring pipeline | EUR 2,000 to 5,000 excl. VAT | Prompts, trade glossary, tests on 20 meetings |
| Review interface and PDF distribution | EUR 1,000 to 2,500 excl. VAT | Branding, distribution list per project |
| Total project | EUR 6,000 to 15,000 excl. VAT | 5 to 8 weeks |
| Usage cost per meeting | EUR 0.5 to 1 | 1 h of audio transcribed and structured |
| Hosting and maintenance | EUR 80 to 250/month | Depending on volume, EU hosting |
Points of attention
| Topic | Recommendation |
|---|---|
| Participant consent | Announced at the start, mentioned in the invitation |
| Personal data | EU hosting, audio deleted after 30 to 90 days |
| Technical vocabulary | Glossary of 200 to 500 terms (trades, materials, party names) |
| Site noise | Conference mic at EUR 80 to 200, meeting in the site cabin |
| Content responsibility | Mandatory human approval before distribution |
| Contractual value | The approved minutes are the binding document, not the raw audio |
AI does not replace the site manager's judgement: it removes the typing. Review remains essential, especially on dates and amounts.

Thomas, works director of a 150-employee general contractor in Nantes, oversees 12 site managers who each spend 3 hours a week on minutes. Current cost: 12 x 3 h x 45 weeks x EUR 50 loaded = EUR 81,000 a year. With the solution, 45 minutes per week per manager remain, or EUR 20,250. The project costs EUR 12,000, usage 12 x 3 meetings x 45 weeks x EUR 0.8 = EUR 1,300, and hosting EUR 1,800 a year. Net gain in year one: 81,000 - 20,250 - 12,000 - 1,300 - 1,800 = EUR 45,650, not counting disputes avoided.
FAQ
Does transcription work with site noise?
Yes if the meeting is held in the site cabin or office with a conference mic. Outdoors, the error rate can exceed 15%, so it is better to dictate a 5-minute summary after the meeting.
Can we use a consumer tool like those built into video conferencing?
For in-person meetings with your trade-by-trade template, generic tools structure snags and actions poorly. They cost EUR 10 to 30 per user per month but do not produce your standard document.
Do we need an internet connection on site?
No, the app records offline and uploads audio as soon as 4G or Wi-Fi is available. The draft usually arrives 3 to 5 minutes after upload.
Does the data stay confidential?
With EU hosting and APIs configured with no reuse for training, yes. Audio can be deleted automatically after 30 days.
Can the minutes connect to our construction management software?
Yes, through API or export, actions and snags can feed a tool like Finalcad or a construction ERP. Allow an extra EUR 2,000 to 5,000 excl. VAT depending on the tool.
