The problem
Producing fire safety documents is
slow, repetitive and error-prone.
The bottleneck isn't the engineering, it's the documents around it. Where the week actually goes:
Reports built from scratch
Re-entering building data that already exists and rebuilding the same sections on every project.
Mistakes slip through
Change one input and the rest of the report quietly contradicts it. A miss that reaches site can cost six figures.
Finding the answer is slow
Open the PDF, search the term, scroll, and do it again across ADB, BS 9991, BS 9999 and PAS 9980.
And when a project reaches the regulator, the cost of a miss is measured in months.

of decided Gateway 2 applications not approved
35 wks
median approval time for remediation work, against a 12 week target
£230k
cost of that overrun, per building
Sources: BSR data to 28 June 2026. The 23% is the share of decided applications not approved; many more were invalidated before assessment. Cost per week: Centre for Cities, 2025. More on Gateway 2.
The product
Four tools. One brain.
Drawing Reviewer
Full drawing sets reviewed, turning a day of checking into minutes.
Travel distances, exit widths, compartment breaches, cavity barriers. Flagged and marked up, with the fix, not just the fault.

The tool raises the intelligence in the deliverable. The judgement stays human.
How it works
No new workflow to learn.
01
Ask or upload
A question, a drawing set, or a strategy, from the Word plug-in or the web app.
02
It gets to work
Cites, reviews, drafts and calculates, grounded in the guidance and your firm's precedent.
03
You decide
Every output is a proposal that lands as tracked changes. Accept, edit or reject.
The engineer is always in the loop.
Security
Client data never leaves
the firm's control.
Zero data retention
Never used for training
Self-hosted option
Encrypted & auditable
We're not in the data business. We're in the engineering business.
Where project information goes, who can reach it, how long it survives, and what we commit to in writing.
Why it pays
The same team, twice the output.
