Overview of Part 11: Renovation Scope and Application
Part 11 of the OBC Division B applies to existing buildings that have been in existence for at least five years. It provides the framework for how new construction standards are applied to old systems. This includes the classification of existing buildings to determine their current performance levels before any work begins.
Proposed Construction and System Extensions
When extending or renovating a building, the code specifies how new systems must integrate with existing ones. Key areas of focus include:
- New and Existing Building Systems: Ensuring compatibility between modern mechanicals and heritage structures.
- Building Extensions: Regulatory requirements for adding square footage.
- Plumbing and Sewage Systems: Specific standards for upgrading wet services in older layouts.
Performance Level Evaluation and Compensating Construction
One of the most critical aspects of Part 11 is the Performance Level Evaluation. This process assesses whether a renovation will reduce the building's overall safety or structural integrity. If a renovation results in a reduction in performance level, the code requires Compensating Construction.
Compliance Alternatives
Recognizing that older buildings cannot always meet the exact specifications of modern new-build codes, Part 11 offers Compliance Alternatives. These are pre-approved methods to achieve the safety objectives of the OBC without requiring impossible structural changes to an existing building.
