Crosier Kilgour has been involved as the structural engineers for the Club Regent facility since the original 4500 m² building was constructed in 1992. Since that time the facility has had office space additions, a stage addition and an 11500 m² expansion completed in time for the Pan American Games in 1999.
The steel frame building features many long, clear spans to provide the feeling of wide open spaces, a requirement of the jungle theme within the building. In addition, a large section of main floor was left open to facilitate a 60 foot waterfall into the basement. This necessitated special provisions to laterally support the 20 foot high basement walls.
The 1999 expansion project included modifications to the roof of the original building to support an additional built-up snow load as well as modifications to the main floor to support a new walk-through aquarium.
