About the National Construction Code
The National Construction Code (NCC) is an initiative of the Council of Australian Governments (COAG) developed to incorporate all on-site construction requirements into a single code. The NCC comprises the Building Code of Australia (BCA), Volume One and Two; and the Plumbing Code of Australia (PCA), as Volume Three.
Volume One: pertains primarily to Class 2 to 9 buildings.
Volume Two: pertains primarily to Class 1 and 10 buildings.
Volume Three: pertains primarily to plumbing and drainage associated with all classes of buildings.
All three volumes are drafted in a performance format allowing a choice of Deemed-to-Satisfy Provisions or flexibility to develop Alternative Solutions based on existing or new innovative building, plumbing and drainage products, systems and designs.
To assist in interpreting the requirement of Volume One, the ABCB also publishes a non-mandatory Guide to Volume One each year. For Volumes Two and Three, clearly identified non-mandatory explanatory information boxes are included in the text to assist users.
