D-LINIEX AI Verifier

Your project checked against the entire regulatory framework
before anyone else reviews it.

Upload your documentation in PDF, DWG, IFC, BC3 or DOCX. The AI runs 6 phases of analysis, cites every breached article, gives you real-time technical chat and generates a downloadable PDF report. All in a single tool.

The regulatory framework, indexed

It isn't 57 regulations. It's the whole framework, layer by layer.

From the CTE and national regulations to the provincial, county and municipal planning of more than 2,400 municipalities, plus Supreme Court case law. All searchable with AI.

Example of findings — real project

CRITICALCTE DB-SI 3.1

Evacuation route exceeds 25 m on the ground floor

The distance measured from the door of the assembly room to the building exit is 31.4 m. Article 3.1 of DB-SI limits this route to 25 m for Public Use without sprinklers.

ERRORCTE DB-HE 2.2.1

Main façade transmittance exceeds the climate limit

U = 0.72 W/m²K. For climate zone D3 (Cáceres) the limit value is U ≤ 0.50 W/m²K per Table 2.3.

WARNINGCTE DB-SUA 1.3.2

Ramp gradient not evidenced in the documentation

The report describes an access ramp but does not state the gradient. Verify that it does not exceed 8% per SUA 1.3.2 for public use.

INFOEHE-08 Art. 37

Exposure class not declared for the foundation slab

It is advisable to declare the exposure class per EHE-08 Art. 8 to justify the minimum cover adopted.

Two sample reports on the same single-family home in Cáceres. The standard one tells you what fails in planning, the CTE and sectoral regulations. The Lince one tells you which Supreme Court rulings affect you and how to protect yourself before signing.

Standard report

AI Verifier

4 CRITICAL9 WARNINGS

20 issues in planning, the CTE and sectoral regulations, with a CONDITIONALLY FAVOURABLE verdict. Basement outside the buildable footprint (which would deny the licence), geotechnical study missing, garage without fire compartmentation… plus 6 anticipated pathologies and 7 construction recommendations.

Everything that a planning-approval objection — or a cost overrun on site — would have made you discover too late, detected before submitting anything.

Lince report

AI Verifier · Premium

TEN-YEAR LIABILITY

It includes the entire standard report and goes further: it recalculates the structure (detecting 2 non-compliant elements) and the energy (HE0 fails), cross-checks each defect with real Supreme Court rulings (verbatim text and ECLI) and delivers an action plan to protect you. 28 pages.

Ten years answering with your assets and your insurance. A single undetected defect can turn into a six-figure claim. This exists so that it never gets there.

Technical chat

Ask about regulations.
An answer in seconds

The technical chat queries the library in real time and answers by citing the specific article, the document and the page. It does not just give generic text: it searches the 50,000 fragments and returns the precise reference.

  • Answers with article and regulation citation

Technical regulations chat · D-LINIEX
What is the minimum parking provision for a residential building on consolidated urban land in Extremadura?
Under DECREE 7/2007 of Extremadura (Extremadura Planning Regulation), for consolidated urban land the minimum provision is 1 space per 100 m² of residential floor area in buildings over 500 m². If the building exceeds the threshold, you must justify it in the planning report. Bear in mind that the municipal PGOU may be more restrictive, as it prevails over the regional standard on this matter. Would you like me to also look up the regulations for the specific municipality?

📖 Decree 7/2007, Art. 74 · Extremadura Planning Standards

04

Case law

The case law that
could rule against you, analysed before you sign.

The verifier does not stop at the regulations: it cross-checks your project with real Supreme Court and Provincial Court rulings on construction defects and the professional's liability (LOE Art. 17). It does so in two ways.

  • Cendoj case law corpus: Supreme Court (Civil and Administrative) and Provincial Courts.
  • Focused on construction defects and the liability of the agents under the LOE.
  • Each ruling mapped to the limitation period that binds you: ten-year, three-year or one-year.
  • Cited with its reference (ECLI) so it is verifiable, not a stray data point.

Via technical chat

Quick query

Ask about a finding or a topic and the chat brings you the relevant ruling: what the Supreme Court decided in cases like yours and why it affects you, with its reference.

Via audit · Lince

Deep analysis

In the deep audit, each critical defect is cross-checked with a real ruling, mapped to your civil liability (ten-year / three-year) and tells you how to proceed to protect yourself.

“…normal habitability is prevented, turning the use into seriously irritating or annoying.”

ask yourself.

Talk to the team
Is it safe to upload my projects?

Yes. Files travel encrypted over HTTPS and are stored on secure cloud infrastructure in the European Union. Your documentation is not used to train AI models: it is yours alone and you can delete it whenever you want.

Does the verifier replace the professional?

No, and it does not aim to. It is a support tool: it detects possible breaches and cites the specific article so that you decide. The signature, the judgement and the responsibility for the project remain with the competent professional.

And if the AI gets it wrong?

Each finding comes with the exact article citation so you can verify it in seconds. It is not a free chat: they are typed workflows with structured, auditable output. You always validate the result before acting.

Which file formats does it accept?

PDF, DWG, DXF, IFC (BIM), BC3 (FIEBDC quantities), XLSX and DOCX. You can upload a single file or a ZIP package with the whole project, up to 50 MB.

Which regulations does it cover?

The complete CTE (SE, SI, SUA, HE, HR, HS), the Structural Code and EHE-08/EAE, sectoral regulations (RSCIEI, RITE, REBT, RIPCI), the regional regulations of all 17 autonomous communities and Cendoj Supreme Court case law on construction defects and the liability of the agents.

Do I need a card to try it?

No. You register and get 25 free credits to get started (≈ 1 Lince audit or 2-3 standard ones), plus queries and AI chat. No card and no commitment.

Can I cancel whenever I want?

Yes. The plans have no tie-in and payment is handled securely via a certified payment gateway. You cancel with one click from your dashboard whenever you need to.
