Definition for building complexity

Closes 1 Nov 2020

Opened 22 May 2020


The defined term for 'Building complexity' has been developed in response to a decision of the Building Ministers’ Forum (BMF) that a definition be prepared regarding the design, construction and certification of complex buildings. This work has been undertaken by the Building Confidence Report (BCR) Implementation Team in addition to delivering the Building Confidence National Framework.

The definition has been developed as a risk-based classification system for the purpose of being used as a trigger for additional regulatory interventions to assist with the design, construction and certification of complex buildings.

Why We Are Consulting

The BMF, at its meeting on 23 April 2020, agreed that the Australian Building Codes Board (ABCB) publish, on its website, the definition for building complexity. The consultation period will be open for a six-month period, during which time further work will be undertaken by the ABCB on the related regulatory interventions, in consultation with states, territories and industry stakeholders.
