The challenge: The Moolarben Coal complex is situated within the Western Coalfields of NSW. The project involved the existing Moolarben Heavy Vehicle workshop which included service bays, a welding bay, store and two storey offices. As the floor area of the two storey offices exceeded 10% of the total floor area of the building and the offices were not fire separated from the remainder of the building, the whole building was considered to be two storeys.
Our solution: The design of the HVW was unable to comply with the general requirements for a large isolated building under deemed-to-satisfy provisions of the Building Code of Australia. This was due to restrictions on fire brigade perimeter access and that the building was not sprinkler protected. As a result, Exova Defire were engaged to demonstrate that the design limits the risk of fire spread from other buildings and that building occupants could undertake safe evacuation. This was despite the non-provision of sprinklers within the building. We also demonstrated that adequate open space and perimeter vehicular access was available to facilitate fire brigade intervention.
