The AI agent for architects: draft the tender documents, support compliance
Drafting the tender documents pack and its technical parts, keeping up with standards and analysing tenders take up a considerable amount of time — without amounting to the value you bring: design. Your AI agent prepares this documentary, repetitive work. Hosted in France — on local inference or an isolated resource — your projects and your copyright stay under control. The architect designs, checks and signs.

First version ready — to be read over and completed.
⛓ Sourced · the project brief + the practice's templates
I am preparing a draft set of consultation rules and a form of tender, for your approval.
✎ Action · documents ready to read over — the architect approves and signs
In an architecture practice or a design team, a Blue Lemon Agent agent drafts the contract documents — technical specifications by package, administrative clauses, consultation rules, form of tender, priced breakdowns and schedules of unit prices — supports regulatory compliance (the 2020 environmental regulation, accessibility, fire safety) and analyses the tenders received. Design (drawings, the building information model) remains with the architect and their software: the agent works on the documentary, the regulatory and the analytical side. It runs on local inference or is hosted in France: your projects are never exposed to a foreign service, architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity. Live within a few weeks.

Why AI matters to practices — and why they hesitate
Public works contracts call for bulky tender document packs, compliant with the Public Procurement Code and with technical rules that keep moving. Time spent drafting and checking these documents is mechanically taken from design — and the projects entrusted to you are sensitive material, protected by copyright.
! The issue
The practice is caught between a client that expects complete, compliant files and a documentary load that keeps growing (technical specifications, administrative clauses, consultation rules, priced breakdowns, statements, tender analysis). Yet most consumer AI tools amount to entrusting projects, briefs, specifications and the practice's know-how to a third party, often hosted outside Europe and subject to the Cloud Act.
✓ Our answer
AI is only of interest to a practice if it is sovereign and confidential by design. Local inference or an isolated resource hosted in France, systematic human oversight, the decision and the signature reserved for the architect: time gained on documentation is never paid for in lost confidentiality or lost copyright. The aim is not to replace the designer, but to give them back time to design.
Confidentiality of your projects: sovereignty & copyright
A practice handles protected projects and the know-how that makes it valuable. Here is how the architecture of our agents protects them, file by file.
Local inference
The agent can run on a machine at the practice: no document leaves the network, nothing passes through a cloud.
Hosting in France
Otherwise, a dedicated and isolated resource, hosted in France under French law — your projects: processing and access within the European Union targeted by the architecture.
Reduced extraterritorial exposure
For your projects, the architecture aims to reduce exposure to the Cloud Act and FISA 702; being located in France or in the European Union does not, on its own, guarantee immunity: the American hyperscalers have no access, even when hosted in Europe.
One isolated resource per practice
No pooling: an environment strictly dedicated to your practice, your templates and your projects.
Copyright preserved
Your projects and specifications stay yours; no reuse outside your environment, access recorded and logged.
AI Act: governed deployment
The agent is strictly in support; no document signed automatically; traceability and human oversight from end to end.
What depends on the architecture chosen These points are not general guarantees: they are settled deployment by deployment, in the quotation.
- The applicable location is that of the architecture set out in the quotation and verified before commissioning.
- Local execution is announced only for the configuration explicitly described and accepted in the quotation.
- The applicable isolation depends on the deployment mode set out in the quotation; no dedicated isolation is presumed.
- The events logged, their content, their retention period and who may access them are defined for the deployment chosen.

4 real situations, taken from those that come up most often. Pick one: the exchange unfolds as it would in your organisation.
A scripted demonstration. These exchanges show how the agent behaves — its sources, its refusals, what it leaves to your teams. Nothing is sent from this page, no model is queried here, and the matters named are fictional. That is precisely what we promise your data.
The behaviours shown here — monitoring, automation rules, routing and reminders — are configured with you during deployment, from your tools, your rules and your thresholds.
The architecture points named in these exchanges — location, local execution, isolation, encryption, role-based access, logging — are not a guarantee attached to the demonstration: they are those of the architecture set out in your quotation, and verified before commissioning.
· A bidder question came in yesterday at 17:48 on the school complex tender. The rules require an answer to every bidder, no later than six days before the deadline: you have 4 days left.
· The ground survey is still not on file, 48 days after it was ordered. The foundations specification is on hold, with two clauses left open.
· The services engineer's insurance certificate expired on 31/07. They are a joint contractor on two live projects.
· A construction standard cited in a specification being drafted has been revised. The specification points to the earlier version. morning-watch_4-flags.pdf4 flags · deadline and project
⛓ Source · tender platform, project files, joint-contractor documents, standards base
The question concerns lot 4: the bidder points out that the specification prescribes an insulation thickness the price schedule gives no line to price. They are right, and I checked: the line exists in the specification and is missing from the schedule.
So this is not a question, it is a contradiction between two documents. Answering with an explanation would not be enough — the schedule has to be corrected and reissued.
Two consequences I flag rather than handle: changing a document four days before the deadline may call for an extension; and bidders who have already priced will have to redo that lot.
The draft answer is attached, with the corrected schedule line. Reissuing and extending are the client's decisions. bidder-answer_lot4.pdf1 specification/schedule contradiction · line corrected
✎ Support · contradiction established — issuing stays with the client
Routing follows your organisation: the bidder question to the project leader and to the client, because the client is the one who issues; the ground survey to the project leader, with a chase to the surveyor; the certificate to the office manager, who requests it; the revised standard to the architect drafting that particular specification — not to the whole practice, or nobody reads these messages any more.
With a chase: 24 h on the bidder question, because the deadline is contractual and cannot be recovered; 48 h on the rest. Then a weekly summary to the partner: flagged, dealt with, unanswered — by project, not by person.
Three guarantees, and they hold. I watch what you have given me access to, access by role and withdrawable in one word. Issuing a document on a tender platform, answering a bidder and amending a published document stay acts of the practice — they bind the client, and they are signed. And what the net catches is counted: over the last quarter, 31 deadlines flagged, including 4 bidder questions inside 24 h of the contractual deadline and 7 certificates reaching expiry. It tightens with every source you open to me, and the weekly summary states each week what went unanswered.
✎ Proposal · watch and chases to be configured — you set the thresholds
Completeness: seven bids are complete. Two are not — one has no technical statement, the other no ten-year insurance certificate for its lot. These are formal gaps, and the tender rules say what happens to them; I do not decide that.
Comparison against the stated criteria — price 40%, technical value 40%, programme 20%: the table is attached, with each bid's score on each sub-criterion and the sentence from the statement that justifies each score.
Two things that deserve your eye: the lowest bid on lot 2 is 31% below the estimate, and its statement addresses none of the three method points the rules require; and two bids on lot 5 carry identical unit prices, to the euro, on eleven items. bid-analysis_school-complex.pdf9 bids · 7 lots · scores justified
⛓ Source · tender rules, bids received, estimate
Three things remain to be decided, and none of them is a calculation:
· The two incomplete bids — exclude them, or ask them to put things right where the rules allow. That choice bears on fairness between bidders.
· The bid at −31% — an abnormally low bid is not excluded because it is low, but after the bidder has been given the chance to justify it. Only the client can make that request.
· The eleven identical prices on lot 5 — this could be one subcontractor pricing for two firms. It could be something else. I record the coincidence, I do not name it: the word that comes to mind is an accusation, and I will not level it off a price table.
The analysis report is ready for the committee, with these three questions at the front rather than in an appendix. The client awards the contract — the practice informs that decision, it does not take it.
✎ Support · report ready — the award belongs to the client
The reason is not procedural. A default value stops being an assumption the moment it is filed: it becomes a figure declared by the design team, under its responsibility, and "we will adjust later" assumes somebody remembers what needs adjusting.
Eleven figures are missing, and they are not equivalent:
· Four are in the file and had simply not been carried across. I have carried them across, each with the document it comes from.
· Five depend on the thermal study, which has not been delivered. No value can stand in for them.
· Two turn on a design choice that has not been settled. That is not a missing figure, it is a decision.
The notice is three-quarters complete, and the seven remaining boxes state what is missing and who holds it. environmental-notice_7-missing-figures.pdf11 figures · origin of each
⛓ Source · project file · 4 figures recovered, 7 flagged
Two of the five missing figures bear on items that drive the result of the study: filling them at random does not produce an approximate notice, it produces a notice whose conclusion no longer relates to the building.
What I can do instead, and have done: the thermal engineer has been chased twice, with no reply. I have prepared the formal request, with the order date, the two chases and the filing deadline now approaching — a document that protects you if the delay is later argued about.
And a proposal, if you approve it: this kind of awaited document can track itself. Order, stated deadline, chase at 15 days then at 5, flagged to the project leader, and beyond the deadline, to the partner — with the summary given by project.
Nothing would be filed, signed or completed by me. The tracking counts the days; it fills no box. formal-request_thermal-engineer.pdfOrder + 2 chases · filing deadline
✎ Action · formal request ready — filing stays with the practice
· Environmental regulation notice — 14 pages, 47 figures carried over from the file; the 5 missing ones are named, with who holds them and the date they are expected. None is filled in for them.
· Accessibility — 9 pages. The 22 points your file allows to be established are drafted: clear widths, gradients, turning circles, accessible WC, parking. Three points come out of the drawings themselves and call for a design decision: a ramp measured at 5.8% on the site plan, an external route at 1.20 m over 4 metres, and an accessible WC whose turning circle is blocked by the door swing. All three are located, dimensioned, and traced to the drawing and revision that carry them.
· Fire safety — 11 pages: building classification, occupancy per floor, escape routes, smoke control, firefighting provision. One point cannot be closed from the office: the distance to the nearest fire hydrant is verified on site or with the relevant service. The request is written and waiting to be sent.
A figure that does not flatter me: across the last three projects my draft notices came back with 9 corrections on average — 6 concerned design decisions that are not mine to take, but 3 were transcription errors, all in the fire safety notice. The way it is built has changed: every occupancy figure and every escape route now carries the drawing and revision it comes from. On this project, rework fell to 1 correction across the three notices. You read them, you correct them, and it is your signature that files them.

· Mareuil secondary school (2021) — closest to what you need, handed over with no snags on that lot.
· Aubel hall (2019) — similar geometry, but a different substrate.
· Verne library (2022) — this detail was the subject of a snag at handover, cleared in 2023 after rework. The rework changed the upstand.
The third is the most instructive, and it is the one a keyword search would have surfaced first, because it is the most recent. Reusing it as drawn means reusing what had to be redone.

What has to be looked at to transpose it, and I have already set it side by side: the substrate, the exposure and the room classification — all three differ between the original project and yours, and the six values sit on one line, each pointing back to the document it comes from. I surface the precedent and the difference; the technical judgement is yours, and it is made on one page instead of two files.
An observation that goes beyond your question: that snag is linked to this detail nowhere in your base. I found it by putting the minutes and the sheet side by side, because I read both. A colleague looking for this detail in your files will see only the sheet.
What I can do, on your approval: at every snag clearance, attach the snag to the detail concerned and mark the original sheet. No sheet would be withdrawn or corrected — it would be marked, which is a different thing: a deleted sheet leaves a hole, a marked sheet says why it changed.
