AFC AG is one of Switzerland’s largest dedicated fire-engineering consultancies, developing building-specific fire-safety concepts for new-build and refurbishment and coordinating architecture, building services and the fire authorities. Its specialists run risk-based, performance-based verifications — smoke-extraction and tenability (ASET/RSET), CFD/FDS smoke simulation, Pathfinder evacuation modelling and structural fire design. Its engineering analyses are an aid to the responsible professional’s judgement, not a substitute for it.
