New Australian Standards for Structural Steel Design (AS4100:2020) & Installation (AS5131:2016 Amd 1 2020)

These recent revisions represent best practice (but are not yet called up in the National Construction Code (NCC) as they were released after the NCC 2019 Amendment 1 earlier this year).

Both of these documents include many changes, notably the introduction of a construction category (CC) rating. This is required to be nominated in the project specification.

Please ensure you check your contract / specification / structural drawings to clarify the need to use these standards and ensure your fabrication subcontractors are made aware of these recent changes so they are appropriately certified for the works and to ensure appropriate allowances are made. This is especially important for the most stringent CC rating (CC3 & 4) which includes third party testing.
