What We Do
Evidence, examined against the question being asked.
Many construction product questions cannot be answered by a single data sheet, certificate or test report. The Bench reviews the evidence, maps it against the actual question, and produces clear written outputs the project team can use.
We work for project teams, manufacturers, distributors and contractors — anyone holding paperwork that does not quite answer the question being asked of it.
Evidence first. Claims second.
Most enquiries start with a question the paperwork does not quite answer
Work usually starts when a project, a product claim or a submission is held up by one of these situations:
Six kinds of problem. One method.
Whatever the route in, the method is the same: the question is pinned down first, the evidence is read against it, and the position — including its gaps and limits — goes to you in writing.
Evidence review
The documents you have — data sheets, test reports, classifications, certificates, drawings — reviewed against the question actually being asked. We check whether the product, thickness and version match the evidence; whether the document is the kind of evidence the question needs; and whether it covers the proposed substrate, fixing, exposure and use.
Where it lands: what the evidence supports, what it does not, and what remains unclear — in writing. Offered as a defined service: construction product evidence review.
Technical investigation
Deeper examination of a build-up, product or system where the evidence needs working through rather than checking off — the question reframed properly, the evidence assembled and weighted, conclusions in calibrated language with confidence stated.
What that looks like in public: Investigation 001 — cavity vs no cavity.
Evidence-gap identification
The gap check separates what is supported from what remains unclear — often the most important part of any review. A gap may exist because the tested build-up differs from the proposed one, the certificate does not cover the project detail, or a performance claim is not linked to any source document.
Where it lands: a gap list your team can act on, flagged before it becomes a project problem.
Comparison and option review
Products, systems or technical routes compared on what their evidence supports — not on headline claims. We check whether the evidence bases are genuinely comparable, where application limits differ, and where one route has clearer evidence than another.
Where it lands: a comparison note separating direct evidence, partial evidence, assumptions and missing information. Offered as a defined service: product comparison review.
Technical written guidance
When Building Control, a design team or a client raises a query, we identify what the comment is actually asking for, review the documents against it, and set out in writing what is supported, what remains unclear and what should not be overstated.
Where it lands: a structured written response the project team can review, use and keep on record. Offered as a defined service: Building Control query support.
Decision support
When the answer is not yet clear, the realistic options from here, set out in order — what each one needs, who to ask, what to request, and ready-to-use questions for suppliers, designers or Building Control so the right people answer the right things.
Where it lands: a written basis your team can discuss and record before committing to a route.
From enquiry to evidence-led response
The aim is not to overclaim or provide approval. The aim is to make the evidence position clearer.
Submit the enquiry
It starts with the technical question — plus the project context, the product or system involved, the proposed detail, the documents you have, and the urgency. Send what you have; the review identifies anything missing.
Intake and triage
We identify the type of question being asked, what information is available, what appears missing, and what kind of output fits. We quote before any written work starts.
Evidence review
The documents are read against the actual question — checking whether the evidence relates to the proposed product, build-up, substrate, fixing, thickness, orientation and performance requirement.
Gap check
What is supported gets separated from what remains unclear. The gap check keeps claims inside the evidence and makes the limits visible — before anyone relies on them.
Written output
The position goes to you in writing — a short technical response, review note, comparison note, gap register, options review or report, depending on the enquiry.
Next steps
Where further information is needed, we identify what should be clarified before a position is relied on — and where a judgement belongs to a fire engineer, designer or Building Control, we say so.
A clear written position
- A written evidence summary — what was reviewed, what it supports, what remains unclear
- A gap list and risk notes, flagged before they become project problems
- The realistic next-step options, in order, with what each one needs
- Ready-to-use questions for suppliers, designers or Building Control
- A written basis your team can discuss and record before committing
What The Bench is not
- Not a certification body, and not a route to guarantee approval
- Not Building Control, and not statutory sign-off of any kind
- Not a designer taking design responsibility
- Not a substitute for project-specific professional judgement
- Not legal advice
Where an enquiry needs one of those roles, we still help organise the question, the evidence and the gaps — but the decision sits with the appropriate duty holder, professional, regulator or approving body.
Send what you have
The more of this that arrives with the enquiry, the faster the review starts — but none of it is required to get in touch:
- The technical question being asked
- Project name and location
- The product or system involved
- The proposed build-up or detail
- Drawings, sketches or photos
- Data sheets, test reports, certificates
- Building Control or project comments
- Deadline and required output
Not sure what applies?
Ask a quick question and we will point you to the right route. The guided technical enquiry walks you through the question, the build-up and the documents step by step — and the review identifies anything missing, unclear or outside scope.
