This user's guide to Part 3 of the National Building Code explains the intent of
many Part 3 requirements and provides a background to and reasons for many of
its more complex requirements. Part 3 - which applies to all buildings
(regardless of area or height) that contain assembly occupancies, care or
detention occupancies, or high hazard industrial occupancies, and to all
buildings of all other categories that exceed 600 m² in area or 3 storeys
in height - is concerned with maintaining the health and safety of the
occupants and assuring accessibility. The guide contains three
commentaries:
- Commentary A, which updates and expands the previously
published Commentary on Part 3
- Commentary B, which provides guidelines for applying Part 3 of
the NBC to existing buildings
- Commentary C, which includes information to assist persons who
are maintaining or modifying smoke-control measures in existing buildings
Whether you are constructing a new building or changing an
existing one, this guide is designed to provide you with the information you
need to design healthy, fire-safe and barrier-free buildings. |
