Section 1.2: Terms, Abbreviations, and Definitions
Understanding the terminology used in Division B is the first step toward successful project execution. The NBC 2025 distinguishes between defined and non-defined terms to provide clarity across various trades and professions.
1.2.1.1 Non-defined and Defined Terms
In the absence of a specific definition in Division A, words and phrases in Division B carry their commonly assigned meanings within the context of the specialized construction industry. This ensures that the expertise of tradespeople and professional engineers is respected in the interpretation of the code. For defined terms, the NBC uses italics to indicate that a specific meaning from Article 1.4.1.2. of Division A must be applied.
1.2.2 Symbols and Abbreviations
Technical accuracy is maintained through the use of standardized symbols and abbreviations. These follow the protocols established in Division A, ensuring a consistent language for building inspectors and contractors like empcontracting.ca Inc. your construction contractor in London, Ontario.
Section 1.3: Referenced Documents and Industry Organizations
The NBC 2025 does not exist in a vacuum; it relies on a network of referenced documents that set the benchmark for material quality and testing procedures. All documents referenced include amendments and supplements effective up to June 30, 2024.
