Resilience is still treated as optional

Fire safety design continues to be framed, in many projects, almost exclusively around life safety. This is entirely appropriate as a minimum objective. It is not sufficient as a sole objective.

Buildings do not exist simply to be evacuated safely. They exist to function. When fire strategies focus only on life safety, they can inadvertently accept levels of damage, disruption and recovery time that are wholly incompatible with the purpose of the building.

This is most visible in sectors where continuity matters: healthcare, education, logistics, data infrastructure, heritage assets. In these contexts, a fire that does not result in loss of life can still represent a significant failure. Extended business interruption, loss of critical services, or irreversible damage to fabric and contents are not secondary considerations. They are central.

Despite this, resilience is often treated as an enhancement rather than a design driver. Sprinklers are value-engineered out where not strictly required. Compartmentation is reduced to meet minimum standards rather than optimised for damage limitation. Detection and alarm strategies are configured for evacuation, not for early intervention. The result is a building that meets regulatory intent, but falls short of operational need.

There is a more balanced approach. Established UK guidance explicitly recognises property protection and business continuity as legitimate design objectives, and fire engineering frameworks provide a structure for considering these outcomes alongside life safety. The tools exist. They are simply not always used to their full extent.

Part of the challenge is commercial. Resilience measures often require upfront investment for benefits that are realised only if something goes wrong. That makes them vulnerable in cost-driven environments. But this is precisely where professional advice should be most robust. The role of the fire engineer is not only to demonstrate compliance, but to articulate consequence.

A building that can be evacuated safely but cannot recover in a meaningful timeframe is, in many cases, under-designed.

Perhaps the shift required is a simple one. Instead of asking “does this meet life safety requirements?”, we should also be asking “what happens the day after the fire?”.

This piece reflects general professional observations and published guidance. It is not project-specific advice, and any design decisions should be based on a full assessment of the relevant circumstances.
