NCC provision A2.2(4) took effect on 1 July 2021. It sets out the formal process and documentation requirements for the development of Performance Solutions, including the preparation of a Performance Based Design Brief (PBDB).
This article explains the relationship between CodeMark Australia Certificates of Conformity (CodeMark Certificates) and A2.2(4), and the steps a construction practitioner should take when relying on a CodeMark Certificate as documentation for a Performance Solution.
CodeMark Certification Scheme
The CodeMark Australia Certification Scheme is a non-mandatory certification scheme that provides a method for verifying that a building product or system meets requirements of the Building Code of Australia (BCA) as nominated in the certificate. A certificate may attest compliance with relevant Performance Requirements based on compliance with Deemed-to-Satisfy (DTS) Provisions or based on compliance with a Performance Solution or a combination of both.
The Conformity Body that issues a CodeMark Certificate is required to undertake an assessment of the product using a process that is equivalent to the process set out in A2.2(4). Therefore, when relying on a CodeMark Certificate to demonstrate that a Performance Solution complies with relevant Performance Requirements, a construction practitioner need not undertake the process in A2.2(4) again. However, it is important to note that a CodeMark Certificate may only certify that a product or system meets some of the Performance Requirements that are relevant to the use of that product or system for a particular project. In these cases, the CodeMark Certificate on its own may not be sufficient to comply with A2.2(4).
Steps to be followed when relying on a CodeMark Certificate
When a CodeMark Certificate is used to demonstrate compliance with a Performance Requirement, the following steps need to be undertaken by construction practitioners:
- Check that the CodeMark Certificate for the building product or system proposed to be used is valid. The JAS-ANZ website contains a register of all valid CodeMark Certificates.
- Check that the CodeMark Certificate certifies the relevant building product or system against all relevant Performance Requirements for the proposed use within the site-specific project.
- For any relevant Performance Requirements proposed to be met by a Performance Solution that are not covered by the CodeMark Certificate, undertake the process in A2.2(4) referencing the CodeMark Certificate and considering the proposed use of the product or system holistically.
- Check any limitations or exclusions set out in the CodeMark Certificate against the proposed use of the building product or system in the site-specific project to ensure they have been met.
