The technical work that drowns you,
solved with rigour.
Your judgement, intact.
Reports, memos and estimates with your data and your standards. What is deterministic, we program with 100% reliable algorithms; the decisions and the signature, always yours. Engineering mindset and rigour, and deep AI domain expertise.
A.01 · FORM & ENGINE
A browser tab.
Not a terminal.
For you, your work companion is a page in your browser (in your favourites): you talk to it in natural language, like chatting, but with all the power of what we have built underneath. That's how you work best: like having a desk companion who knows what to do.
Behind the tab: Claude Code as the engine, plus whichever tools the case calls for (voice, your data, official records). We also build AI apps if the case requires — but the standard format is the companion, because it adapts to you better than a rigid form.
Two paths, depending on where you are now
You don't use AI yet
Start by knowing what it would solve for you today
We walk you through a case of yours, without changing the tools you already use. No commitment.

You already use it and want to go more serious
Jump to the technical rigour — and choose how you want to work
A companion that knows your work, without starting from scratch. You choose the collaboration format.

Sound familiar?
The time eaten by technical paperwork
Hours each week on documentation that needs your format, not your head: memos, reports, code-compliance forms, estimates.
The error caught too late
A miscopied figure, a repealed standard, a number that doesn't add up. In work with consequences, errors cost dear.
«We tried ChatGPT and it made up data»
Generic AI doesn't know your work or your drawings. It gives you an answer you have to redo — or worse, that you have to believe.
More work than hours — and projects you turn down
Day-to-day doesn't stop. And sometimes you say no to work you could take — not for technical capacity, but for lack of hours.
If you recognise yourself, you don't need another generic tool. You need an AI that understands your work.
Already tried it with ChatGPT?
| ChatGPT (generic AI) | Your companion | |
|---|---|---|
| Does it know your industry? | No. Each time, you bring it up to speed. | Yes. It knows your standards, criteria, and how you sign. |
| Does it work with your files? | You paste them, each time. | Connected to BC3, Excel, PDFs and folders — already knows them. |
| And work with consequences? | Makes things up when it doesn't know. | What is deterministic, programmed with 100% reliable algorithms. The rest, it flags — and you sign. |
| Is it yours or do you rent it? | Indefinite monthly fee. | We build it and it's yours. No fee for the tool. |
An AI that knows your work
— and does the heavy lifting
Engineering
Automated report from the project folder
Drop the project folder (field sheets, boreholes, drawings). Pick up the report ready to review. From ~5 h to ~15 min.
→ Proven with a geotechnical engineering firm of national reference.
Architecture
Project documentation companion
Municipal folder + memos + BC3 → estimate. Eleven councils, eleven formats. The correct folder, done.
→ Proven with a nationally recognised architecture studio.
Construction
Tender radar + voice CRM
You speak between site visits; Monday they're investigated leads. ~10 HOT and ~12 WARM filtered each week.
→ Proven with a leading construction firm holding an international patent.
And the time you recover?
You turn it into business.
How we do it (no smoke)
Rigour that's programmed
What can be solved deterministically, we program with 100% reliable algorithms — we don't leave it to the lottery of a chat. Verified sources, traceability, no making things up.
Knows your work and your data
Not 'general' AI: we configure it with your sector, your criteria, and your documents. It works with your data, in your house, and responds in your format.
Your judgement rules, always
You set the limits, the exceptions and the signature. The companion does the heavy lifting; the decisions with consequences, you make them.
Want to know where this rigour comes from? Not from a chat: from programming.

We start with a pilot
Claude Code, you can install it yourself.
What we bring, you can't.
Custom MCPs for your tools
Validated pipelines
Invisible professional techniques

What you recover
Real example (anonymised): a geotechnical engineering firm went from about 5 h to about 15 min per report.
We do the math with your numbers on the call. No inflated figures: yours.
How do you want to work with us?
Claude Code Implementation
Plan approved · executed · paid · yours
- · For those with a clear project and budget now.
- · Fits irregular revenue: you invest when you can.
- · We agree the plan, approve it, execute it. Paid, yours.
- · Optional maintenance so the companion keeps learning from your real use.
AI Department
Like an in-house department — contracted out
- · For those who would hire an internal AI role — but don't want the payroll commitment.
- · You prioritise, pause, and re-prioritise based on your projects. The control is yours.
- · Continuous learning of the companion is part of the service, not an add-on.
- · We work with few clients at a time; real cadence.
You can start with one format and move to the other if your situation changes.

In 48-72 h
What the companion would do, what it costs, how much time you recover.
4-8 weeks
We build it, connect it to your tools, and put it in motion.
And it's yours
We teach you how to use it and stay to make it grow with you.
Frequently asked
I.01What does Eficients do exactly?+
We configure an AI to know your technical work —engineering, architecture or construction— and do the heavy lifting: reports, memos, estimates, document folders. With your data and your standards. You bring the judgement and the signature.
I.02Do I need to know IT or have an IT department?+
No. Just the files you already have (BC3, PDFs, Excel). We set it up.
I.03Doesn't AI make up data?+
What can be solved deterministically we program with reliable algorithms; sources are verified, and your judgement validates always. We don't leave work with consequences to the lottery of a chat.
I.04Do I have to change my tools or migrate to BIM?+
No. The companion connects to what you already use.
I.05Is it rented or mine?+
Yours. The companion stays with you; we don't charge a monthly fee for the tool, only for the expertise to grow it if you want.
I.06Where do you work?+
In Catalonia (and across Spain via partners), with a real person on the line.
Shall we talk about your work?
30 minutes, no commitment or pitch. We listen and tell you honestly if we can help — or if you don't need us.
