The Australian National Construction Code (NCC) is produced and maintained by the Australian Buildings Code Board (ABCB) on behalf of the Australian government and each state and territory government.
The NCC is given legal effect by relevant legislation in each state and territory. This legislation prescribes or 'calls up' the NCC to fulfil any technical requirements that are required to be satisfied when undertaking building work or plumbing and drainage installations.
The NCC comprises three volumes:
Volume 1 contains detailed fire-related provisions.
The NCC assessment process comprises the following:
|Determine building classification||According to Part A3 based on the purpose for which the building is designed, constructed or adapted.|
|Determine required fire resistance of the building or structure||Within the NCC Vol. 1, Section C establishes the performance requirements and verification methods for fire resistance and is divided into three parts:|
Specification C1.1 establishes the requirements for fire-resisting construction of building elements, expressed as the required Fire Resistance Level (FRL) for various building elements for various building classes and types of construction. The FRL is given in minutes for structural adequacy/ integrity/ insulation. For example, a fire-resisting lift or stair shaft for an industrial building three-story high (class 8, type B) is required to have an FRL of 240/120/120.
|Assess FRL of building elements||NCC Vol. 1 Specification A2.3 governs assessment of fire resistance of building elements:|
