A fire strategy authored to bound the project, not to satisfy a checklist. 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.
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 — no ambiguity over what is claimed, on whose authority, and against which standard.
