AUST – HENDRY building surveyors advise that the Building Code of Australia in Part C2 ‘Compartmentation and Separation’ contains clause C2.3 ‘Large isolated buildings’. A number of HENDRY building surveying design clients appear to need help in the explanation of this clause relative to fire compartmentation in Class 7 and 8 buildings.

Building Code of Australia: Part C2 – Issue

Requirements and considerations designers must apply to large fire compartments.

Building Code of Australia: Clause C2.3 – Explanation

A fire compartment in a building can exceed the limits prescribed in the Building Code of Australia. For a Class 7 and 8 use where the building exceeds 18 000 m²/ 108 000 m³, only the fire compartment that exceeds the limits in Table C2.2 need to be provided with smoke exhaust or smoke heat vents. The whole building however must be protected by a sprinkler system and provided with perimeter vehicle access in that case. For a typical large single storey building, such as a warehouse or factory, (Class 7 and 8 ) Type A construction can apply due to concessions for the single storey columns resulting in a fire compartment up to 5000 m²/ 3000 m³. Fire compartments that do not exceed these limits do not need to have smoke exhaust/ venting requirements in the building.
