Fire engineering is the application of a ‘first principles’ approach to the analysis of fires and smoke behavior leading to the development of appropriate life safety systems for a building. This allows WalkerBai Fire Engineering to develop design solutions that are tailored, allow new technologies to be used, enable cost-effective construction and provide architectural freedom to inspire. The performance requirements in the BCA allow an integrated suite of fire safety systems to be developed and tailored for each individual building. By taking into account the characteristics of the building and its occupants our fire safety engineers develop active and passive fire system solutions for the design, construction and occupation of the building.
