PFP Engineering Judgements & Remediation Reviews
Where a passive fire protection detail cannot be directly matched to standard tested evidence, project teams may need a formal engineering judgement, assessment or specialist tech
nical review. Our support can help with:
- Independent review of PFP engineering judgements and assessed details
- Evidence checks for fire stopping, cavity barriers and service penetrations
- Review of wall-heads, shaft walls, board encasements and steel protection interfaces
- Identification of evidence gaps, limitations and non-standard site conditions
- Clear recommendations to support remediation, inspection and close-out

Technical Review For Non-Standard PFP Details
IFI Group supports clients, contractors, designers and dutyholders by reviewing the available evidence route, identifying limitations and helping define a clear close-out process for passive fire protection defects, non-standard details and remediation proposals.
This support is particularly useful where site conditions differ from the tested detail, where installation records are incomplete, or where a proposed remedial solution needs to be checked against available product data, manufacturer guidance, fire test evidence and project requirements.
What We Review
IFI Group can review passive fire protection engineering judgements, fire stopping assessments, manufacturer details, proposed remediation routes and supporting evidence packs.
Our review work can include fire stopping assessments, board encasement evidence, structural steel fire protection proposals, wall-head interfaces, service penetrations, shaft wall remediation, cavity barrier interfaces and hybrid passive fire protection details where different systems or substrates meet.
We can also support projects where existing installation evidence is incomplete, where a tested detail does not appear to match the site condition, or where remedial works need further technical review before they are accepted, inspected or closed out.
When An Engineering Judgement Or Remediation Review May Be Needed
A PFP engineering judgement or remediation review may be needed when the installed passive fire protection detail falls outside a standard tested arrangement or cannot be clearly verified against the available evidence.
This can happen when services differ from the tested configuration, apertures are larger than expected, substrates are different, annular gaps vary, access is restricted, or several passive fire protection systems meet at a complex interface.
It may also be needed during remediation schemes, intrusive inspection works, quality audits, handover reviews, Regulation 38 evidence pack preparation or project close-out where the client needs a clearer understanding of what can be accepted and what remains unresolved.
How IFI Supports The Design Team
IFI Group can provide independent technical comments to help project teams understand whether the evidence route is clear, whether the proposed detail appears aligned with the site condition and whether further information is required before close-out.
Our support can include reviewing drawings, photographs, pin records, defect schedules, product data, test evidence, manufacturer details and proposed remedial solutions.
We can help identify gaps, compare site conditions with the judgement, recommend additional manufacturer input and define inspection requirements, hold points or further opening-up where the available evidence is not sufficient.
What Good Evidence Should Include
A robust engineering judgement or assessed detail should be clear about the evidence it relies on and the limitations that apply.
This should normally include the tested basis, field of application, product limitations, substrate limitations, service conditions, fixing details, aperture size, annular gap, fire resistance period, responsible author, assumptions and any restrictions on use.
Where these details are missing, unclear or inconsistent with the site condition, the judgement may need further review, manufacturer input, additional inspection evidence or competent fire engineering support before it can be relied upon.
Best Fit Projects
PFP engineering judgement and remediation review support is well suited to commercial fit-outs, residential remediation schemes, high-rise residential buildings, healthcare projects, education buildings, government offices, CAT-A and CAT-B fit-out interfaces, construction close-out and projects where passive fire protection evidence packs need further review.
It is also useful where different systems meet, where work has been completed by multiple contractors, or where defects have been identified during passive fire inspections, fire stopping inspections, cavity barrier inspections or structural steel fire protection reviews.
Supporting Remediation & Close-Out
Passive fire protection remediation often involves more than simply replacing a defective detail. Project teams need to understand why the original detail was defective, what evidence supports the proposed replacement, and how the remedial works will be inspected and recorded.
IFI Group can support remediation reviews by helping clients assess the available information, identify evidence gaps and define practical next steps. This can help improve the quality of close-out records and reduce the risk of unsupported details being accepted without suitable evidence.
Our approach is designed to support clear decision-making between clients, contractors, designers, fire engineers, manufacturers and dutyholders.
Important Limitation
An engineering judgement is not the same as a fire test report. It normally relies on existing test evidence, product knowledge and competent assessment of whether a proposed or installed detail is supportable.
IFI Group can help review the evidence, identify limitations and support the close-out process, but product-specific judgements may require input from the manufacturer, test house, certification body or competent fire engineer.
Where a detail falls outside the direct field of application, the review should clearly identify what can be supported, what remains non-verified and what further evidence or formal assessment may be required.

PFP Engineering Judgements & Remediation Reviews FAQs
Is an engineering judgement the same as a test report?
No. A test report records the performance of a tested system under specific conditions. An engineering judgement usually relies on existing test evidence, product knowledge and expert assessment to determine whether a non-standard or varied detail may be supportable.
The limitations, assumptions and field of application must be clearly understood before the judgement is relied upon.
Can IFI approve untested passive fire protection details?
Untested or non-standard details should not be accepted without suitable supporting evidence, assessment or competent fire engineering justification.
IFI Group can review the available evidence, identify gaps and help advise whether further manufacturer input, formal assessment, opening-up or specialist review is required.
Can IFI prepare all engineering judgements?
IFI Group can support engineered solutions and provide review comments within the agreed appointment scope.
However, product-specific judgements may require input from the product manufacturer, test house, certification body or a competent fire engineer.
Where this is required, we can help identify the limitation and recommend the appropriate route for further confirmation.
When should an engineering judgement be challenged?
A judgement should be challenged where the tested basis does not match the site condition, where services differ from the evidence, where substrates are different, where the aperture or annular gap is outside scope, or where the proposed detail is not clearly supported by the field of application.
It should also be questioned where the responsible author, assumptions, restrictions or supporting evidence are unclear.
Can this support passive fire remediation works?
Yes. PFP engineering judgement and remediation review support can be valuable during remediation works because it helps project teams understand which details are supportable, what evidence is missing and what inspection or close-out records may be required.
This can help reduce uncertainty before works proceed and improve the quality of the final evidence pack.
What documents should we send for review?
Useful information can include drawings, pin records, photographs, fire strategy information, defect schedules, product data, test reports, assessment reports, manufacturer guidance, installation records and any proposed engineering judgements or remedial details.
The more complete the information pack, the clearer the review outcome is likely to be.
