Building Code of Australia

Aged Care Facilities

AUST - We have noticed that some aged care providers may potentially have Building Code of Australia compliance headaches in relation to their facilities. Aged care facilities generally fall into Class 3 (Aged Care Hostel), Class 9a (Nursing Home) and Class 9c (Aged Care Building) within the Building Code of Australia. The introduction of Class 9c buildings in the Building Code of Australia provided building owners, aged care service providers and designers with some certainty regarding the “Ageing in place” concept. Class 9c buildings are ‘aged care buildings’, which are defined by the Building Code of Australia as being a ‘building

Fire Windows: Protection of Opening

AUST - Hendry advise that the Building Code of Australia (BCA) in Part C3 ‘Protection of Openings’, nominates fire windows under Clause 3.4 ‘Acceptable methods of protection’. This clause allows for the use of windows as an acceptable method of fire protection in walls requiring a FRL. The requirement for protection of window openings under the Building Code of Australia is to protect life and property from the risk of flame and heat transmission. This article explains the parameters under the Building Code of Australia that allow fire windows to be nominated in building works. Building Code of Australia Clause C3.4

Fire Rating Services Risers

AUST - Hendry reports on a common Building Code of Australia (BCA) compliance design problem encountered on multi storey buildings that arise from design proposals for services risers, including mechanical air handling risers to open directly into a plantroom. To the contrary, compliance with the Deemed-to Satisfy requirements of Clause 2.7 of Specification C1.1 of the Building Code of Australia necessitates 120/120/120 FRL (dependant of Class of building and would not require a structural FRL) lids and fire dampers, or fire rated ductwork to the point of discharge in the case of smoke exhaust systems or the like, unless otherwise justified

Non Deemed to Satisfy External Wall Cladding Systems

AUST - Hendry advises that in recent years, residential and commercial buildings in Australia have seen a dramatic increase in the use of innovative, external wall cladding systems which are not covered within the Building Code of Australia (BCA) deemed-to-satisfy (DtS) provisions and building regulations. When these systems are proposed in the design of a new building or building upgrades they are required to be presented as Alternative Solutions. The Alternative Solution must include evidence that allows the relevant authority to determine that the material and the form of construction proposed in the design meet the Performance requirements in the BCA. It

Fire Rated Masonry: Building Code of Australia

AUST – HENDRY building surveyors advise that the Building Code of Australia and various Australian Standards require that the design of buildings incorporate specific measures to mitigate the effects and risk of fire. Fire rated masonry is an integral part of providing safety for buildings. Where elements of buildings are required to be fire rated under the Building Code of Australia, such as for load bearing walls, building boundary walls or walls to fire stairwells, the materials used in their construction also need to be fire rated. The Building Code of Australia requires these materials to be tested under laboratory conditions

BCA: AS/NZS 3666.2: AS 1657: Fixed Platforms, Walkways & Stairways

AUST – HENDRY building surveyors advise that providing proper access to your mechanical ventilation and hot water, warm water and cooling water systems in your buildings under AS 1657-1992 ‘Fixed platforms, walkways, stairways and ladders – Design, construction and installation’ Part I1.2 of the Building Code of Australia requires mechanical ventilation and hot water, warm water and cooling water systems in a building other than a system only serving a single sole-occupancy unit in a Class 2 or 3 building or Class 4 part to be maintained in accordance with AS/NZS 3666.2: 2002 ‘Air-handling and water systems of buildings – Microbial control

Disability Access: Unisex Toilet: Building Code of Australia

AUST – Hendry advise that the Building Code of Australia allows a unisex facility required for people with a disability, may be counted once for each sex under Clause F2.2(c ) for the calculation of the required number of sanitary facilities to be provided. This therefore means that if for example in a building permit application there is a requirement for a toilet block to contain 10 toilets (5 for the male and 5 for the female) the installation of a single unisex toilet for disability access will mean that only 9 toilets will be required (4 for the male, 4

Tread Nosings in the Building Code of Australia

AUST - HENDRY building surveyors advise that the 2014 Building Code of Australia (BCA) has introduced criteria for the slip resistance of treads or tread nosing strips and stair landings. Slip resistance must be shown to comply with AS 4586. The table below specifies the required rating to be achieved. Circumstances Dry Wet Tread or landing surfaces P3 or R10 P4 or R11 Nosing to tread or landing edge P3 P4 It is common practice to use nosing strips on treads and stair landing in order to achieving compliance with the BCA.

Building Code of Australia: Part D1: Provision for Escape: External Stairways of Ramps

AUST – HENDRY building surveyors advise that our clients ask us what protection is required to protect the occupants using an exit path from exposure to a fire within the building. The exit stair is required to be protected from any part of the external wall of the building which has a fire resistance rating of 60/60/60 or any openings in the external wall that are located less then 6.0m from the stair. Clause D1.8(c)(ii) permits fire rated enclosure to be constructed to provide a shield so as to protect the occupants using the exit stair from exposure to a
