This zoo houses one of the largest primate collections in North America, including the Western Lowland Gorilla. The zoo recently announced the addition of new gorillas into its exhibit. In an effort to renovate the Gorilla Exhibit for additional space, the zoo approached Advantic, LLC, regarding best practice modifications to its existing structure. The zoo requested that an interconnected chute be fabricated to provide additional space for movement and observation for these territorial creatures. With over one million visitors annually, the zoo also wanted to create the least amount of disruption to both primates and other neighboring habitats.

Advantic, LLC, recommended an elevated tunnel design outfitted with FRP (fiber reinforced polymers) which provided the gorillas with a 360-degree view of their habitat. The elevated tunnel was constructed with wide flange beams, angles, plate, I-beams, and channels. 1.5" HD-7000 was also used as the chute’s flooring, which can easily support the 450-lb. weight of a typical male Western Lowland Gorilla. 

Initially designed out of stainless steel, Advantic’s value engineered FRP design met all structural requirements and reduced the need for costly and restrictive rigging, lifts, and cranes required to move and install heavy steel components. All FRP beams were hand carried into the exhibit through the only available access point - a single personnel door. The FRP structure was installed with four craft workers in seven days, 50% faster than the steel estimate. This reduced interruptions, loud noises, welding hazards and intrusive movement to the gorillas, zookeepers, and the public.
