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.

For the school refurbishment contract, prepare the technical specification for the structural works package from the brief and our practice's template.
Brief and template read. Technical specification "Package 02 — Structural works" drafted by chapter (foundations, walls, floors, environmental requirements). 2 points to settle: the type of foundations depends on the ground survey, still missing from the file; one insulation requirement to be confirmed against the thermal target.
First version ready — to be read over and completed.

For an organisation established outside the European Union, the law of its own country applies; at its request, we put equivalent safeguards in place (human review before any action, a log of the criteria, information for the people concerned).

✦ In brief

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. Data hosted in France; the AI model is called at its publisher, except with the Sovereign model option. With that option, 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.

Included in the package: hosting and AI consumption up to the volume of your capacity tier, in documents, exchanges, tokens and storage; beyond that, re-invoiced at real cost with no margin, tracked in your client area as usage statements are issued. Maintenance and supervision subscription for an initial term of 12 months for the Agility package, 24 months for the Serenity package and 36 months for the 100% Sovereign package, renewable; support levels (SLA 72 h / 24 h / 4 h) optional. Bespoke development, additional integrations or exceptional volumes are quoted separately. Support Monday to Friday, 9am to 6pm. Prices exclude VAT.
AI model: none of the AI models offered currently carries a fixed surcharge. When the selected model carries a cost, that cost is shown when you choose it, before you order, and re-invoiced at the cost incurred, with no mark-up; usage is billed at the publisher's price. Publishers' prices are published in US dollars: the amount re-invoiced is the amount in euros actually borne by Blue Lemon Agent on the publisher's invoice, at that invoice's exchange rate, with no commission or mark-up.
Included components and additional components Components included in the base offer: the Blue Lemon Agent software foundation, the AI models listed in the order journey, the standard channels (Microsoft Teams, Slack, WhatsApp Business, email, website chat, calendars, Microsoft 365 / Google Workspace, file storage, market VoIP telephony, professional social-media pages and accounts, Google Business Profile), hosting for the package chosen, in France by default, backups, supervision, updates and support. If adapting the AI agent to your constraints, your needs or your requests requires other paid components — a third-party publisher's software licence, paid API access to one of your applications, hosting of health data, for which French law requires an HDS-certified host (art. L. 1111-8 of the French Public Health Code), SecNumCloud-qualified hosting, a speech synthesis service, particular hardware —, they are offered to you as an option or on quotation and re-invoiced at the cost incurred; nothing is committed without your written agreement. Where the artificial intelligence model you choose entails an additional cost, that cost is shown to you before you order and re-invoiced to you at the cost incurred, with no margin.

Use cases

The uses of AI in an architecture practice

What the agent does in an architecture practice, and the neighbouring agents we deploy for the rest. The agent carries out by itself what you authorise it to do; you decide what it does on its own and what it submits to you. Design remains yours.

Included in your agent The 2 capabilities essential to this promise are included, at no extra cost.
From 256 € excl. VAT / month

Regulatory statements

Environmental regulation, accessibility, fire safety: draft statements from the project data, to be approved.

Brief statement & formatting

Formatting the brief and the statements from your data; design remains yours.

Controls and safeguards These 2 controls are built into the agent: they frame what it does, whatever plan you pick. They are not chosen and are not added to your order.
Human oversight, costs, quality, incidents and safe stop Explain alerts, scenarios and operational trade-offs
What the agent must be connected to These 3 connections are required for the agent to work. They concern your information system and are scoped during the audit.
Handoff contracts, least-privilege permissions and shared context Connect ERP/WMS/MES/IoT without creating double entry Honour constraints, statuses, approvals and error recovery

Demonstration

See the agent at work

5 everyday 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.

Fictional simulation — not a client result

Four flags this morning, with no request from you.
· 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 bidder question — can you answer it directly?
I draft the answer, I do not issue it. An answer to a bidder is not a letter: it is a tender document, it applies to everyone, and it changes every bidder's file.
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
How did you spot all that? And who do you tell?
I watch, continuously, what you have opened to me: tender platforms and their deadlines, documents each project is waiting on, joint contractors' certificates and their validity, and the standards cited in your written documents. A clock running, a document that does not arrive, a certificate expiring, a standard moving — I say so, I do not wait to be asked.
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.

The context

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.

The decisive point

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

With the 100% Sovereign package, the agent runs on a machine at the practice: no document leaves the network, nothing passes through a cloud.

Hosting in France

Otherwise, with the Agility and Serenity packages, a dedicated, isolated resource hosted in France, under French law: data hosted in France; the AI model is called at its publisher, except with the Sovereign model option.

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 carries out what you have authorised; 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.
For the most sensitive contracts and data, SecNumCloud and HDS options are available depending on your requirements. A single architecture is designed to answer both the GDPR and extraterritorial exposure. Designed for deployment in line with the GDPR and the AI Act, after the processing, roles and context-specific risks have been assessed.
The gain

How much time can an agency recover?

By automating the drafting of contract documents and documentary checking, a practice can aim for an appreciable reduction in the time spent on the tender documents and on tender analysis — reinvested in design and in the quality of the project.

Frequently asked questions

Your questions, our answers

Does the agent design the drawings or the building information model?
No. Design (drawings, modelling, building information modelling) remains with the architect and their software (Revit, ArchiCAD and the like). The agent works on the documentary, regulatory and analytical side — no drawings or models are generated.
Are the technical specifications and documents produced reliable?
The agent produces a first version in line with your templates; the architect checks it, completes it and takes responsibility for it. It is a saving of time, not a substitute: no document is signed automatically.
Does it handle public works contracts?
Yes: it prepares a tender documents pack and its parts (technical specification, administrative clauses, consultation rules, form of tender, priced breakdown) in line with the Public Procurement Code, with thresholds kept up to date. On the buying side, we also offer a dedicated "public procurement" solution for contracting authorities.
Are my projects and data protected?
Yes: hosting in France, a resource isolated per practice, access recorded and logged. Your projects and your copyright are preserved, architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity.
Do we have to change software?
No. The agent complements your existing tools (design software, document management, practice templates) without forcing a migration. We adapt the integration to your working environment.
How long does it take to deploy an agent?
A few weeks as a rule, after a 30-minute meeting with our sales team that identifies the use case with the best return, then a phase of design, integration and testing before going live and training your team.
