National Construction Code (NCC)

The NCC incorporates 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.

Building Code of Australia and Plumbing Code of Australia Amendments

Please visit the VBA Seminar Series pages to find information on amendments to the Building Code of Australia relevant to building, and amendments to the Plumbing Code of Australia relevant to plumbing practitioners.

Building Code of Australia

The Building Code of Australia (BCA) is produced and maintained by the Australian Building Codes Board (ABCB), which is an initiative of the Council of Australia Governments.

The BCA provides a uniform set of technical provisions for the design and construction of buildings and other structures.

The BCA is performance-based and allows for state variations to provide additional requirements or cater for specific community expectations. This means it defines the way of achieving a specified outcome without prescribing a particular method.

Copies of the BCA (Volumes One and Two of the National Construction Code) are available free of charge from the Australian Building Codes Board website.

Plumbing Code of Australia

The Plumbing Code of Australia (PCA), forming Volume 3 of the NCC, is administered and maintained by the Australian Building Code Board (ABCB). The ABCB is a joint initiative of Federal, state and local governments and reports to state, territory and Commonwealth building ministers. In Victoria, this is the Minister for Planning.

The PCA contains the technical provisions for the design, construction, installation, deemed to satisfy method for a particular plumbing installation, or where a plumbing practitioner wants to use an innovative approach to an installation. A Performance Solution may be used for any installation, and must be developed prior to the work being carried out.

How to develop a performance solution

Plumbing practitioners intending to use a performance solution for their plumbing installation need to be aware of the process and requirements for this method.

For a high level summary of how to develop a performance solution, view this video.

The VBA has also developed an industry guide for Victorian practitioners outlining the expected process, documentation and requirements to be followed.

In addition to the VBA's industry guide, the Australian Building Codes Board also has further information on performance solutions available at
