A fire strategy authored to bound the project, not to satisfy a checklist. JWCS authors fire strategies rail-led throughout, across railway infrastructure and non-rail buildings alike. The document sets out the design fire, the escape provisions, the compartmentation logic, the active and passive systems strategy, and the assumptions the rest of the design relies on. It is the reference every downstream discipline cites.
The governing code is selected by premises class. Railway premises are designed under BS 9992; non-rail buildings other than dwellings under BS 9999 and Approved Document B Volume 2; residential buildings under BS 9991. The frameworks are held distinct and are never conflated. JWCS has delivered fire strategy design on a non-rail building under Approved Document B Volume 2 through an embedded, client-confidential engagement; residential fire strategy authoring under BS 9991 is not yet delivered. This buildings capability is developing, a nascent delivered record on held, rail-applied standards literacy applied under the same first-principles discipline; railway infrastructure remains the core specialism and the body of delivered experience.
JWCS works from first principles where prescriptive guidance doesn’t bound the case (BS 7974 performance-based engineering), and prescriptively where prescriptive routes deliver compliant outcomes efficiently. Every strategy carries a documented Qualitative Design Review, named design fires, and explicit boundaries between performance-based and prescriptive routes.
Strategies are issued at gate reviews against the project’s GRIP / Pathway / RIBA cadence. Sign-off authorities, derogations under sub-surface regulation or S1088 routes, and key design assumptions are surfaced explicitly, with no ambiguity over what is claimed, on whose authority, and against which standard.
