Fire Safety Due Diligence, Compartmentation Verification & Asset Assurance Reviews
Portfolio Asset Assurance Reviews
Construction & Material Analysis
Compartmentation Verification
Project Overview
Gilfillan Murray Consulting Ltd was commissioned to undertake fire safety due diligence and asset assurance reviews across a range of residential, healthcare, commercial and public sector buildings. The commissions were typically linked to asset acquisition, disposal, portfolio review, planned investment, refurbishment or wider compliance assurance where the client required a reliable understanding of the building’s existing fire safety position.
The work extended beyond a standard fire risk assessment. The focus was to establish how the building had been constructed, how key fire-resisting elements performed and whether the available evidence was sufficient to support future commercial, operational or compliance decisions.
The reviews commonly involved the identification and evaluation of compartment walls, compartment floors, fire-resisting construction, passive fire protection systems, service penetrations and historical alterations. In many cases, the client required confirmation of whether the building’s existing construction could be relied upon, whether further intrusive investigation was required or whether future remedial works should be anticipated as part of asset planning.
Turning uncertainty into verifiable fire safety evidence
Providing building owners and asset managers with a clearer understanding of compartmentation, fire-resisting construction and passive fire protection performance to support informed commercial, compliance and investment decisions.
The Challenge
The principal challenge was that many buildings had been altered, refurbished or extended over several decades, often without a complete and reliable record of the works undertaken.
Drawings, fire strategies and historic specifications did not always match the construction found on site. Some compartment lines shown on drawings could not be readily confirmed, and the fire resistance of walls, floors or structural elements was not always supported by certification or clear construction evidence. In other cases, later service installations, refurbishment works or layout changes had affected the original passive fire protection arrangements.
The client therefore required more than a list of defects. They needed a clear view of what could be verified, what remained uncertain and what impact those issues could have on future sale, acquisition, refurbishment, occupation or compliance planning.
Our Approach
The review process combined document analysis, site inspection, construction evaluation and targeted intrusive investigation where required.
Existing reports, surveys, certification records and management information were reviewed to identify gaps, inconsistencies and areas requiring further investigation. Where information was unavailable or incomplete, this was clearly recorded rather than assumed.
The assessment focused on understanding the building as constructed. Compartment lines were reviewed against available drawings and site conditions. Walls, floors and protected routes were assessed to determine their likely fire-resisting role within the wider fire strategy. Where construction was concealed, opening-up works or further verification were recommended to establish material type, build-up, continuity and likely fire resistance performance.
The review also considered the interaction between passive fire protection and other fire safety measures, including escape routes, fire doors, service penetrations, risers, voids, smoke control and management arrangements. This allowed individual findings to be assessed in the context of the building as a whole rather than treated as isolated technical observations.
Strategic Impact
These commissions highlighted a recurring issue across existing building portfolios: important commercial and compliance decisions were often being made without a verified understanding of the fire-resisting construction on which the building depended.
A building may appear adequately documented, but drawings and historic records do not always confirm the current condition, construction type or fire performance of critical elements. This is particularly important where buildings are being prepared for sale, acquisition, refinancing, refurbishment or inclusion within a long-term investment programme.
The reviews demonstrated the value of combining construction knowledge, fire safety expertise and physical verification to establish a clearer understanding of how buildings actually perform. By examining compartment walls, fire-resisting floors, passive fire protection systems and concealed construction details, the assessments converted uncertainty into usable technical evidence.
This provided a more robust basis for asset planning and helped clients understand whether risk sat within the building fabric, the available documentation, historic alterations or future maintenance obligations.
Outcomes
The completed assessments provided clients with a verified understanding of critical fire-resisting construction within their buildings.
Compartment lines that had previously existed only as drawing information were checked against site conditions. Construction materials were reviewed, likely fire resistance was evaluated and the relationship between passive fire protection measures and the wider fire strategy was clarified. Where uncertainty remained, the client received clear direction on the specific areas requiring further investigation or future remediation.
This enabled building owners and asset managers to distinguish between elements that could reasonably be relied upon, elements requiring remedial action and areas where further evidence was needed before significant decisions were made.
The findings supported asset transactions, refurbishment planning, compliance reviews and long-term maintenance programmes by providing a more accurate understanding of the building’s existing fire safety performance. Clients were able to target future expenditure more effectively, reduce uncertainty around critical fire safety features and make decisions based on verified construction information rather than historic assumptions.
