NCC 2019 Out of Cycle Amendment

June 23, 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:

  • Volume One Clause D1.18 (new) – New requirement for 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.

  • Volume One and Two Clause A5.7 (new) – New Clause that includes reference to a new Technical Specification for the permanent labelling of Aluminium Composite Panels. This will apply to all types of regardless of Aluminium Composite Panels regardless of the core type.

  • Volume One Specification C1.1 Clause 3.10 (Type A Buildings) and Clause 4.3 (Type B Buildings) (existing clause) – Changes to existing clauses to clarify the intended application of the concessions for 3 and 4 storey Class 2 and 3 timber framed buildings, to specify that it only applies to the timber framing and does not extend to a concession for other elements such as use of cladding other than that permitted by C1.9 under the Deemed-to-Satisfy Provisions.

    Note, these changes do not affect cladding for Class 1 and 10 buildings or buildings of Type C construction.

  • Volume Two (existing clause) – Corrections to fix an error in NCC 2019 to a requirement that would’ve otherwise required inclusion of anti-ponding devices/boards for unsarked tiled roofs.

  • All NCC Volumes Clause A2.4(4) (new) – New Clause included that specifies administrative provisions that all Performance Solutions, regardless of the building class or solution complexity, would be required to undertake and include the preparation of a performance-based design brief.

  • A number of minor NCC 2019 corrections have also been made.

What buildings do the amendments affect?

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.

A number of minor NCC 2019 corrections have also been made. HIA was successful in advocating for addressing the error that required anti-ponding devices to be installed for tile roofs regardless of sarking being installed which had resulted in unnecessary costs and regulatory burden. Disappointingly HIA has raised further errors that are causing issues for the industry but these have not been addressed in the amendment.

When does the Amendment take effect?

The out of cycle amendment will take effect in all states apart from Western Australia from 1 July 2020, for Western Australia it will take effect in line with NCC 2019 adoption on 1 May 2021.

The new Performance Solution process elements, however, are subject to an additional 12 month transitional period and will take effect from 1 July 2021.

What does this mean for NCC 2019 itself?

The changes as noted above are only to a select number of provisions in NCC 2019, whereas the remainder of NCC 2019 provisions are unaffected. Therefore, you just need to familiarise yourself with those new clauses where relevant to your project, and the remainder of the NCC 2019 are unchanged.

As such if you have already purchased a copy of NCC 2019, it is still relevant and it is just the additional clauses you should either download or print off to include in the hardcopy.
