At empcontracting.ca Inc. your construction contractor in London, Ontario, we specialize in interpreting these complex regulations to streamline your permit process.
Key Compliance Alternatives for Industrial Renovations
When working with existing industrial properties, strict adherence to new construction standards isn't always physically possible. These alternatives ensure safety while acknowledging the constraints of older buildings.
Exits, Stairs, and Hardware (F48 - F61)
- Stair Design: Existing stairs are generally acceptable if they are visually apparent and meet specific rise requirements (C.A. F49).
- Panic Hardware: Under C.A. F61, existing functionally operable panic hardware is permitted, saving significant costs on hardware replacement.
- Heritage Considerations: Public heritage buildings benefit from specific relaxations regarding occupant load and stair configurations (C.A. F59).
Fire Safety and Separation Standards (F62 - F70)
One of the most critical aspects of industrial retrofitting is fire protection. The OBC Table 11.5.1.1.-F offers several alternatives:
- Fire Separations: C.A. F69 allows for a reduction in fire-resistance ratings (e.g., 1 hour instead of 2 hours) in specific scenarios, provided other safety measures are met.
- Fire Escapes: Combustible fire escapes may be reconstructed or recreated, particularly in heritage contexts, provided they meet fire protection standards (C.A. F62).
- Vertical Shafts: Significant flexibility is granted to existing elevator shafts and service rooms, provided they are not classified as high-rise under Subsection 3.2.6.
Environmental and Service Systems (F71 - F73)
Existing mechanical and service systems are often permitted to remain if they meet flame-spread ratings or are supported by modern sprinkler systems, ensuring the building remains functional during its transition.
