This unit of competency specifies the outcomes required to advise on the application of National Construction Code (NCC) performance requirements for performance-based solutions for buildings up to three storeys, and to apply approved assessment methods to determine whether a proposed solution is compliant.The unit applies to assessing architectural drawings and specifications for performance-based solutions and analysing them in relation to the relevant sections of the Building Code of Australia (BCA) and the Plumbing Code of Australia (PCA). The unit supports the work of building surveyors who:provide advice to architects and building designers on compliance requirements and options for performance-based solutions, oract in the statutory role with responsibility for assessing the compliance of performance-based solutions and certifying those that are compliant.Under legislation the building surveyor is responsible for ensuring that there is no conflict of interest between the two roles. The building surveyor cannot advise on, and then certify, the same performance-based solution.Licensing, legislative, regulatory or certification requirements apply to this unit in some States. Relevant state and territory regulatory authorities should be consulted to confirm those requirements.
