txt Building Code of Australia: Class 1 and 10 buildings (Volume Two, 2022)

Preface

Each volume of the NCC is split into two main sections:

• Administrative requirements contained within the Governing Requirements.
• Technical requirements contained within the remaining sections of the NCC.

The Governing Requirements provide the rules and instructions for using and complying with the NCC. They are vital in understanding how the technical requirements of the NCC should be applied to any particular situation. The Governing Requirements are also important in understanding how the NCC fits with the building and plumbing regulatory framework within Australia.

The NCC uses a uniform clause numbering system across each of its three volumes. This system is called Section-Part-Type-Clause (SPTC). In each clause number—

• The first letter indicates which NCC Section sits within, or if the letter S is used, that the clause is part of a Specification. The letter S is used in place of a Section indicator because the same Specification may be called up in several different Sections of the NCC.
• The first number indicates the number of each Part within a Section, or the number of a Specification. Parts are numbered sequentially within each Section, starting at 1. Specifications are numbered sequentially across all three volumes, also starting at 1.
• The second letter indicates the clause Type. It will be G, O, F, P, V, D or C and these are explained below.
• The second number is the clause number within each Part or Specification.

The clause Types used in the NCC are as follows:

• G = Governing requirement (mandatory)
• O = Objective (guidance)
• F = Functional Statement (guidance)
• P = Performance Requirement (mandatory)
• V = Verification Method (optional)
• D = Deemed-to-Satisfy Provision (optional)
• C = Clause in a Specification (clauses in Specifications may be mandatory or optional, depending on how the Specification is called up by the NCC).

Informative parts of the NCC (e.g. Introduction to the NCC) are not numbered and do not have numbered paragraphs. This helps make it easy to see that their content is information only and does not contain any regulatory requirements.
