Introduction to the National Construction Code (NCC)

• The NCC is Australia’s primary set of technical design and construction provisions for buildings

NCC Clause Types

• Governing Requirement (G): Mandatory requirements that must be met.
• Objective (O): Guidance for achieving a particular outcome.
• Functional Statement (F): Guidance on how to achieve a desired performance.
• Performance Requirement (P): Mandatory requirements specifying the desired outcome.
• Verification Method (V): Optional methods for verifying compliance.
• Deemed-to-Satisfy Provision (D): Optional provisions that, if followed, are deemed to satisfy the requirements.
• Clause in a Specification (C): Clauses in specifications may be mandatory or optional; this depends on the specification's inclusion in the NCC.

NCC Volume One: Content and Overview

• Focus: Covers technical design and construction requirements for buildings categorized as Class 2 to 9, encompassing multi-residential, commercial, industrial, and public assembly buildings, along with their associated structures.
• Scope: Includes access requirements for people with disabilities in Class 1b and 10a buildings, and certain Class 10b structures including access requirements for people with a disability in Class 10b swimming pools.
• Structure: Organized into Sections A through J, with additional schedules for abbreviations, symbols, definitions, referenced documents, and state and territory variations/additions.

NCC Volume One: Section Overview

• Section A - Governing Requirements: Contains mandatory requirements that govern building design and construction.
• Sections B to G and I to J: Include mandatory performance requirements and pathways for compliance with the NCC.
• No Section H: The letter "H" is used for the corresponding section in NCC Volume Two to avoid numerical clashes.
