A fire strategy is the master document that frames every fire-related design decision through the lifecycle of a railway asset. JWCS develops strategies from concept through to detailed design, working from first principles where prescriptive guidance does not bound the case.
The approach is performance-based where the asset and use-case demand it, and prescriptive where prescriptive routes deliver compliant outcomes efficiently. Every strategy is built around a documented Qualitative Design Review under BS 7974, with clear assumptions, design fires, escape provisions, compartmentation logic, and integration with fire systems.
Strategies are issued in revisions tracked to the project’s design gate sequence. Sign-off authorities, departures from standards, and key design assumptions are surfaced explicitly — there should be no ambiguity in what is being claimed, on whose authority, and against which standard.
JWCS strategies are commonly accepted by infrastructure-owner technical authorities, principal contractors, and competent-authority approving bodies, including under the UK Fire Precautions (Sub-Surface Railway Stations) Regulations 2009 regime where applicable.
