Session Synopsis

With various negative consequences including property damage, high remediation costs, and even structural failure, corrosion is a perennial problem for the construction sector. Indeed, according to research, it costs the Australian economy upwards of $30 billion annually.

Acknowledging this – and acknowledging the widely-held view that its previous iteration (NCC 2019) did not adequately address the issue – NCC 2022 has modified its approach to corrosion prevention. To summarize, the new regulation matches best practice in terms of coating systems.

While this is a step in the right direction, problems remain. For example, despite the regulatory changes, specifiers still don’t have a mechanism to assess micro-climates (around pools, in shaded areas, around footings, etc.), which are exposed to ponding water and, therefore, highly susceptible to corrosion.

This CPD Live session examines the new provisions for coatings in the NCC, as well as other corrosion-related regulations, including AS 4100 and AS 5131. Noting their strengths and limitations, our speakers outline what they see as best practice when it comes to corrosion management in 2023.

By the end of this session, you should be able to:

• Outline the prevalence of corrosion in the built environment and identify its negative impacts.
• Identify the legislative framework surrounding corrosion, including the NCC and relevant standards.
• Explain the ways NCC 2022 differs, in terms of its approach to corrosion management, from NCC 2019.
• Identify the ways in which this regulatory framework is still deficient.
• Outline the ways that specifiers need to go beyond the regulatory requirements to achieve best practice corrosion management.
