The NCC Update of 2019, and What it Means
What Happened This Year?
In early 2019, a new Australian Standard for the design of post-installed and cast-in concrete anchors was referenced in the NCC 2019. It applies to safety-critical applications.
This update aims to maintain consistency and accuracy of clear rules associated with designing and testing structural anchors.
Who Drives It?
With the advice and support of a leading body of experts, the NCC update was driven by the Australian Engineered Fasteners and Anchors Council (AEFAC), an organisation that was founded to ‘enhance the specification, selection, design and installation of structural anchors and fasteners in the Australian construction industry’*.
The AEFAC consortium was formed by Swinburne University of Technology in conjunction with a group of construction supplies and tools companies. This consortium also collaborates to conduct research and development in order to advance the industry.
So, the NCC – What Is It?
‘NCC’ is an abbreviation for the ‘National Construction Code’. The government-enforced code ‘provides the minimum necessary requirements for safety and health; amenity and accessibility, and sustainability in the design, construction, performance and liveability of new buildings (and new building work in existing buildings) throughout Australia.’
The code is divided into three volumes:
- Vol 1 – Class 2 and 9 (multi-residential, commercial, industrial and public) buildings and structures.
- Vol 2 – primarily applies to Class1 (residential) and 10 (non-habitable) buildings and structures.
- Vol 3 – applies to plumbing and drainage for all classes of buildings.**
There are many applications of cast-in and post-installed anchors that would be covered by any of these three volumes: where anchors are used to fasten steel structure to concrete like with carports and sheds, where concrete anchors are used to fasten heavy u bolts and the like in plumbing and piping situations, in heavy load environments such as with the fixing of pre-cast concrete panelling and more.
What Was the Change?
Previously, the NCC recognised anchors complying to the SA TS 101:2015 technical note as suitable for applications in all three volumes. Through consortium collaboration and new research results becoming available via each consortium members’ engineers, an updated standard has been introduced – AS 5216:2018 – which now holds updated data and in turn authority to be recognised as an advancement on SA TS 101:2015. Therefore, any anchor that meets the requirements of AS 5216:2018 is also compliant with the NCC.
What Are Suppliers Doing?
The change has seen construction supplies businesses in Australia acting quickly to replace and update certification and Technical Data Sheets relating to their NCC-compliant fastening range. These updates re-conform the products as compliant with the NCC moving forward until such a time that the AEFAC implements another update.
Most sellers of anchors in this category now have a collated range of NCC-compliant anchors for cast-in and post-installed anchors. And any builder looking to apply the code to any fastener they are considering using in concrete are encouraged to consult with these companies, particularly if they feature an in-house engineer as part of their per-sale consultation service.
