Cited answers for UK fire engineers
Fire engineering AI
AI built for UK fire engineers. Guidex answers from the guidance you select, and cites every answer to the exact clause, table or figure.

What is fire engineering AI?
Fire engineering AI is software that helps fire engineers find, apply and record what the guidance says. Guidex reads the guidance you choose and works from your project parameters, so you get the clauses that apply to your building.
It takes on the searching and the cross-referencing. The engineering judgment stays with you.
Why general AI is a risk in fire engineering
A general model has read thousands of clause references, so it knows their shape. When an answer needs a reference and none is available, it can fill the shape anyway. The result looks correct, and it is not real.
The risk is not the obviously wrong answer. It is the one that survives your read-through.
| Point | General AI tools | Guidex |
|---|---|---|
| Source | The open web and general knowledge | Only the guidance you select |
| Citations | Can be invented | The exact clause, table or figure, which you can open |
| No answer found | May guess | Tells you |
| Context | Generic | Filtered to your building |
The hallucination control model
Guidex is built on a hallucination control model with a human-in-the-loop framework. The model supplies the reasoning. The documents supply the content.
- Find. The question finds the relevant passages first.
- Read. The passages are read in stages, so tables keep their notes and clauses keep what they depend on.
- Draft. The answer is drafted only from what was found.
- Verify. A separate pass checks each factual claim against the source. If it does not match, it is withheld.
- Check. The engineer stays in the loop, and can open every source.
From general intelligence to fire engineering expertise
Guidex is built in layers. Each layer narrows a general model toward fire engineering, with the engineer in control.
- 01Foundation modelsSeveral large language models, run privately.
- 02CalibrationTuned across its full set of generation controls for precise, repeatable answers.
- 03Grounded regulatory knowledgeGrounded in Approved Document B and British Standards. Every answer traces back to its source clause.
- 04Spatial intelligenceTrained on commercial and residential layouts, so it reads real building geometry.
- 05Human-in-the-loop frameworkBuilt into every output. It keeps the engineer in control and reduces bias.
- 06GuidexSource-traceable, engineer-led fire engineering intelligence.
What you can do with it
- Ask. Get answers in plain English, cited to the exact clause, table or figure.
- Review a layout. Upload a floor plan. Guidex maps the spaces and escape routes, then reviews the layout against the guidance.
- Mark up a design. Place compartment lines, fire doors and travel distances, with each note connected to the guidance behind it.
- Draft a report. Reach a first draft in your company’s template with fire strategy AI.
- Draft an FRAEW. Work in your template, with pre-site-visit markups and site inspection findings carried into the report. Read the PAS 9980 guide.
- Keep a record. Every output carries an audit trail with the model specification, date and scope of use.
What engineers ask it about
Travel distances, compartmentation, means of escape, fire doors and openings, escape stair design, cavity barriers, external wall build-up, fire resistance periods, smoke control, refuge provision, fire service access, evacuation strategy, occupancy and capacity, sprinkler provision, protected corridors and cladding review.
Guidance Guidex reads
Guidex reads the documents you select, such as Approved Document B, the British Standards you work to and other published guidance.

Questions about fire engineering AI
Does fire engineering AI replace a fire engineer?
No. Guidex does not exercise engineering judgment and does not replace a competent person. It gives back the time spent on searching and cross-referencing.
What does human in the loop mean?
It means an engineer stays involved. Guidex proposes and cites, and the engineer checks, corrects and decides.
Who is Guidex for?
UK fire safety engineers and fire engineering consultancies.
Can it read floor plans?
Yes. Upload a floor plan and ask about any stair, room or corridor. You get an answer specific to your building.
Check the source. Then use the answer.
See it on your own project
The quickest way to judge Guidex is to point it at a building you already know and check its answers against your own.
