Mechanical base building upgrades of the iconic Centennial Planetarium originally built in 1967 for the Canadian Centennial. With the construction of the Telus Spark, the science centre moved homes in 2011 leaving this architectural building empty for several years. The base building upgrades were completed in order to give new life to the building, and a new tenant – Contemporary Calgary, opening the building back up as an Art Gallery showcasing modern and contemporary art for Calgarians. The mechanical installations included a complete overhaul of the mechanical room, including demolition of the massive existing steam boilers, and replacement with 2 Aerco Condensing Boilers and AO Smith Hot Water Tanks. The existing Ventilation Unit was completely repaired and refurbished with new Heating and Cooling Coils, Supply and Return Fans with VFD Controllers, and new Dual Duct Boxes and distribution ductwork throughout the building. All plumbing finishes and fixtures were updated to give the building all of the modern amenities to complement the existing architecture.
