NCC 2019 out of cycle amendment

The National Construction Code 2019 Amendment 1 was adopted by all states and territories from 1 July 2020.

The Amendment is the product of decisions by both the Building Ministers’ Forum and the Board, including in response to recommendations of the Building Confidence Report (BCR).

Key changes from the 2019 edition

Early childhood centres

A new provision in NCC Volume One, D1.18 Egress from early childhood centres, prevents application of Deemed-to-Satisfy Provisions in circumstances where an early childhood centre is located on an upper level of a multi-storey building. It follows that in these instances a Performance Solution will be required.

Makes it necessary to use a performance solution when a early childhood centre is situated within a multi storey building.

Early childhood centre means any premises or part thereof providing or intending to provide a centre based education and care service within the meaning of the Education and Care Services National Law Act 2010 (Vic), the education and care Services National Regulations and centre based services that are licenced or approved under State and Territory children’s services law, but excludes education and care primarily provided to school aged children in outside school hours settings.

Labelling of aluminium composite panels

A new provision in the Governing Requirements, A5.7 Labelling of Aluminium Composite Panels (ACP), requires labelling in accordance with Standards Australia Technical Specification 5344.

Each ACP shall be marked with the following information:

  • Name or trademark of the manufacturer
  • Model number, name or designation
  • Date of manufacturer ( month and year is the minimum requirement)
  • Batch identifier or other traceability information

As a minimum the marking shall:

  • Remain legible for the life of the ACP
  • Be human readable. Additional machine readable marking may be included.
  • Remain present post installation
  • Be a minimum character size of 5mm high
  • Have lettering of a contrasting colour or finish to the background
  • Be in English Roman alphabet or numerals 0 – 9, or both

Concession: Class 2 and 3 Buildings

This concession, which permits the use of timber framing for low-rise Class 2 and 3 buildings, has been redrafted to remove ambiguity and clarify application.

It applies to Class 2 and 3 buildings such as apartment and hotel type buildings  that are 3 storeys or less where the external cladding must be non-combustible.

The concession uses the term “notwithstanding”  which sets the boundary for how much  of the NCC part C1.9 Non Combustible building elements is set aside to permit timber wall framing.

Anti-ponding boards

NCC 2019 Amendment 1 will include typographical and diagram corrections to provisions that have errors. NCC Volume Two Part 3.5.2.5 has been updated to clarify that anti-ponding board requirements only apply to roofs where sarking is installed.

An anti-ponding device/board must be provided where sarking is installed on roofs with a pitch less than 20 degrees and sarked roofs with no eaves overhang, regardless of the roof pitch.

Proposed changes

In addition to the above, the NCC 2019 Amendment 1 may contain the following proposed changes that are yet to be confirmed.

Building complexity

A new definition for building complexity may form part of Amendment 1. It provides a rating of complexity that may be used in the future to identify buildings for which additional oversight is appropriate. This proposed change is a response to the BCR National Implementation Framework.

Building complexity is rated on a scale from 0 to 5. For example a house is 0 and a hazardous facility or a hospital is 5. The complexity is determined by assessment of the building against four  criteria being;

  • Complication
  • Organisation
  • Occupants: Number
  • Occupants: Vulnerability

Process for the development of Performance Solutions

This proposed change is a good practice process when developing Performance Solutions. Inclusion of A2.2(4) of the Governing Requirements, including its accompanying note and explanatory information in NCC 2019 Amendment 1, is subject to consideration of impact analysis yet to be completed. This proposed change is a response to the BCR National Implementation Framework.

It proposes a new provision to require that a process be followed to improve the quality of, and documentation for, Performance Solutions.

The mandatory requirements would include four steps for a proposed Performance Solution.

  1. Prepare a performance based design brief
  2. Carry out analysis, modelling or testing
  3. Collate and evaluate results
  4. Prepare a final report

NCC compliance is a statutory requirement, and you should always review and check that your work complies with the applicable sections of the code.
