NCC 2019 Out of Cycle Amendment – WA

June 01, 2020

At the request of Building Ministers, the ABCB has issued an out of cycle amendment to the National Construction Code (NCC) 2019.

What does the Amendment cover?

The main components to the amendment include:

  • Enhanced fire safety measures for early childhood centres in high-rise buildings. This will include limiting child care centres to ground floor only under the DTS Provisions or needing to have direct egress requirements from the floor containing the childhood centre.
  • Reference to a new Technical Specification for the permanent labelling of Aluminium Composite Panels.
  • Clarification of fire concessions for 3 and 4 storey Class 2 and 3 buildings, to specify that it only applies to timber framing and does not extend to a concession for other elements such as timber cladding.
  • Corrections to NCC 2019 including to a requirement that would’ve otherwise required inclusion of anti-ponding devices/boards for unsarked tiled roofs.
  • Specifying administrative provisions that all Performance Solutions, regardless of the building class or solution complexity, would be required to undertake and include a performance-based design brief.
  • A number of minor NCC 2019 corrections have also been made.

The amendments are mostly relevant to NCC Volume One (Class 2-9), but there are elements that will affect Class 1 residential buildings; including the additional administrative requirements for Performance Solutions which will result in increased time for approval, costs in development of solutions, and additional red tape particularly for straight forward Performance Solutions for houses.

When does the Amendment take effect?

The implementation of NCC 2019 for WA will occur as follows:

  • 30 April 2021 - Western Australia’s extended transition period for NCC 2019 as a whole will expire.
  • 1 May 2021 – NCC 2019 is adopted in full in Western Australia, including the out-of-cycle amendment.
    The heating and cooling load-limit caps for energy efficient assessments will continue to not apply that are prescribed in Part J0.2 (Vol 1) and Part (Vol 2) in Western Australia.
  • 1 July 2021 - The new Performance Solution in the NCC out of cycle amendment process elements is implemented across all jurisdictions.

Should I have regard to the out of cycle amendment?

Advisory (Practice and Building) Notes have already been formulated for a number of new provisions, guiding the intended application of revised elements within NCC 2019; including energy efficiency and how to correctly apply the verification using reference building method (including what software tools are excluded from use in using the method), fire performance for timber framed Class 2 and 3 buildings and the developing and documenting of Performance Solutions.

The WA Government and ABCB have encouraged practitioners to familiarise themselves with the content of these Advisory Notes as whilst they are not regulated documents, however, as they relate to guiding how the NCC should be interpreted and applied, practitioners should have regard for these advisory notes and out of cycle amendment.

A copy of these advisory notes and the out of cycle amendments can be accessed from the ABCB website.
