John Ball Zoo Meijer Grizzly Bear Exhibit

JEI Structural Engineering provided specialized zoo exhibit glazing engineering services for the Meijer Grizzly Bear Exhibit at the John Ball Zoo in Grand Rapids, Michigan. Our team designed the structural glass systems that allow visitors to experience close-up views of the animals while maintaining the highest standards of safety, durability, and animal containment.

As a leading provider of animal enclosure glass engineering, JEI works with architects, zoo designers, exhibit consultants, owners, and glazing contractors to develop custom glass and panel systems for wildlife habitats throughout North America.

Structural Glass Design for Grizzly Bear Habitats

Large animal exhibits present unique engineering challenges that differ significantly from traditional building façade systems. Grizzly bears can generate substantial impact forces through charging, jumping, climbing, and interaction with enrichment elements.

The viewing glass for the John Ball Zoo exhibit was engineered to withstand:

• High-impact animal loading
• Dynamic movement and concentrated forces
• Potential impacts from rocks and enrichment devices
• Long-term durability requirements in outdoor environments
• Safety and redundancy requirements for public viewing areas

Typical Glass Design Characteristics

Animal habitat glazing systems commonly utilize:

• Multi-ply laminated tempered glass assemblies
• Multiple layers of 1/2-inch tempered glass
• High-performance structural interlayers such as SentryGlas®
• Redundant safety design to maintain containment even after glass breakage
• Project-specific engineering calculations based on exhibit geometry and animal species

Every zoo exhibit is unique and requires engineering analysis based on species behavior, exhibit layout, loading conditions, and owner requirements.

Grizzly Discovery Deck Glass Floor Engineering

In addition to the primary viewing enclosure, JEI provided engineering services for the Grizzly Discovery Deck glass floor panels.

These structural glass floor systems allow visitors to experience unique overhead views of the exhibit while safely supporting pedestrian traffic. Glass floor engineering requires specialized analysis for strength, serviceability, impact resistance, slip resistance, and long-term performance.

About the John Ball Zoo Grizzly Bear Exhibit

The Meijer Grizzly Bear Exhibit opened in 2013 as part of the John Ball Zoo’s Idema Forest Realm expansion and the broader Restore the Roar capital campaign.

Key features of the project include:

• Large-format animal viewing glass
• Immersive “nose-to-nose” visitor experiences
• Expanded naturalistic habitat environments
• Water features and enhanced enrichment areas
• Public animal care and training demonstration spaces
• Structural glass floor viewing opportunities

The exhibit transformed the visitor experience by replacing traditional viewing barriers with large glass walls that provide unobstructed views while maintaining animal safety and containment.
