PROJECT CHALLENGES
Technical Challenges
Fire Rating Requirements: Ensuring at least a two-hour fire rating for the wall system.
Weight Restrictions
The structural steel design did not allow for CMU due to weight limitations.
Design Challenges
- Proximity to an existing building (200 mm) restricting storage and installation operations.
- Mid-story horizontal girts were not feasible due to column design and associated structural constraints.
- The design needed to account for vertical concrete slab deflection of up to 38 mm.
- The system had to accommodate a maximum vertical span of 6 meters.
- Direct fastening through was not an option
Sequential Installation Requirements
Panels needed to be delivered and installed sequentially due to on-site storage constraints.
Installation without the use of a crane, relying instead on monorails and lifting pulleys.
Design Considerations for Future Modifications
Although the adjacent building currently protects against wind loads, the design accounted for potential future exposure to wind loads if the neighboring building is demolished.
CUSTOM NORBEC SOLUTION
Norbec provided a customized solution featuring fire-rated insulated metal panels (IMPs), along with expert design adjustments and tailored installation recommendations, effectively addressing the unique challenges of the project.
Products used:
- Panel Type: Noroc 6-inch fire-rated insulated metal panels.
- Material: 26/26 gauge steel, Silkline smooth finish.
- Colors: Interior – Bright White; Exterior – Stone Grey.
- Panel Length:
- Standard: 10’4”, easier for shipping and handling
- First Floor: Nearly 20′
- Panel Weight: Panels weighed 6.04 lbs/ft², minimizing structural loads and easing handling.
- Thermal Performance: The 6-inch panel provides a single layer assembly with an R-Value of R-24
DESIGN ADJUSTMENT
Vertical Hat Channels
Eliminated the need for horizontal girts, addressing bothaesthetic and structural requirements.
- Enhanced span capacity.
- Meet deflection limitation (L/180)
Custom Stack Joint Detail
- Allowed for controlled deflection while ensuring secure
attachment. - Prefabricated flashing and trim expedited installation
and improved precision
Monorail Installation System
Monorail and bosom chairs to go with for detailing work
from narrow exterior space were used.
- Adapted to tight site conditions.
- Enabled precise alignment using pulley systems.
- Reduced manual handling and installation time.
Top Edge Panel Clamp
A custom-engineered panel clamp was utilized on the top edge (green piece visible in the raised panel photos) to ensure precise alignment and secure fastening.
INSTALLATION PROCESS
Structural Preparation:
- Load-support angles installed on primary steel.
- Vertical hat channels distributed loads without horizontal girts.
Panel Installation:
- Just-in-time delivery facilitated efficient sequencing.
- Panels installed floor by floor using custom clamps and the monorail system.
- Smaller panels eased transportation and handling on-site.
Deflection Management:
- Stack joint design accounted for floor slab movement.
- Secure bolt-and-nut attachments ensured alignment in restricted areas
RESULT
- Fire Safety Compliance: Achieved two-hour fire resistance as per CAN/ULC S101.
- Structural Load Optimization: Lightweight panels reduced additional load on the building’s framework.
- Thermal Performance: R-24 panels contributed to improved thermal efficiency.
- Efficient Installation: Site-specific tools and methods minimized installation time.
- Structural and Aesthetic Integration: Eliminated horizontal girts while maintaining load-bearing capacity.
- Wind Load Resistance: Panels designed per Canadian building code (2023 Alberta Edition) standards to withstand local wind conditions.
Norbec’s engineering-focused approach addressed the Hampton Inn project’s unique challenges, providing a tailored insulated panel system that met stringent fire, structural, and aesthetic requirements while optimizing installation under constrained site conditions.
