Fire compartmentation instructions are used where a building requires clearer information on compartment lines, fire stopping defects, service penetrations and the practical implications for fire risk and remedial works.
The instruction may form part of wider fire risk management, remedial planning, intrusive review or compliance work where the integrity of passive fire protection cannot be assumed.
Our role is to help clients understand the extent of compartmentation issues, their relative significance and the next actions needed to reduce uncertainty and support remediation planning.
The instruction is relevant where the condition of fire stopping and compartment lines may affect fire risk, building safety planning or the scope of remedial works.
The exact scope depends on access and the building, but the work is generally structured around compartment lines, penetrations, fire stopping quality and the practical implications of observed defects.
Walls, floors, risers and other building elements intended to provide fire separation between areas or occupancies.
Service penetrations, voids, incomplete sealing and other failures that may compromise compartment integrity.
Which issues appear most significant, where further opening-up may be needed and how the findings should inform next-step action.
We begin by understanding the building, the available access and the reason the instruction is being commissioned. That helps frame the level of opening-up, survey coverage and reporting detail appropriately.
Our reporting is intended to support decisions. The aim is not just to list defects, but to help the client understand relative significance, information gaps and what a proportionate next step looks like.

No. A fire risk assessment is broader. Compartmentation review is a more targeted instruction focused on the integrity of passive fire protection and separation.
Yes. The survey often provides a clearer basis for defining remedial priorities, further investigations or contractor work packages.
Yes. Many instructions are carried out in occupied environments where access, sequencing and practical constraints need careful consideration.
