This report analyzes fire regulations within the context of building design, focusing on the Building Code of Australia (BCA) and the National Construction Code (NCC). The assignment addresses key aspects of fire safety, including compliance with deemed-to-satisfy (DTS) provisions, building classification, and fire-resisting construction. It examines the classification of buildings based on their use and characteristics, such as boarding houses and factory/office complexes, and how these classifications influence fire safety requirements. The report determines the 'rise in storeys' for different building types and the required fire-resisting construction for various scenarios. It also explores exit requirements, including fire isolation and aggregate exit width calculations, considering factors like occupancy and travel distances. Furthermore, the report evaluates emergency lighting and exit sign requirements and the application of fire hydrants and hose reels in different building types. The report provides detailed explanations, justifications, and calculations to support the answers, demonstrating a comprehensive understanding of fire safety regulations in building design.
