The Chicago based Council on Tall Buildings and Urban Habitat (CTBUH) Organization is recognized internationally as the authority on hi-rise buildings, not only for statistics, but for design and construction techniques. There are 12 working groups and committees within CTBUH comprised of international professionals that study technical aspects of hi-rise buildings and produce technical guides and professional publications. The current work group subjects include façade access, fire and safety, outrigger building frames, performance based seismic design, sustainability and several other advanced technical subjects.
Mark Garland has been active in the CTBUH for ten years and was recently selected as a Toronto City Representative along with Richard Witt of Quadrangle Architects, Agha Hasan of Yolles, and Abdel Fattah-Toukan of BKCN Engineering to launch a Canadian Chapter of the CTBUH. Executive Director of CTBUH, Antony Wood, was the keynote speaker at the inaugural breakfast event, which occurred on May 2, 2013.
In related news, the CTBUH has declared the Trump International Hotel + Tower to be the second tallest building in Canada, just behind First Canadian Place, of all buildings complete or under construction through the end of 2015. Trump stands 277 meters tall to the tip of the spire. One Bloor East, the Aura and Scotia Plaza range from 238 meters to 275 meters tall. Trump has far fewer storeys than the other buildings because the five star ceiling heights are so generous.
