Claimed as the world’s largest seismicly isolated building, Istanbul, Turkey’s new 200,000-sq-meter Sabiha Gökçen International Airport terminal opened at the end of October. Designed for a 7.5 to 8.0 moment magnitude quake and built in just 18 months, the roughly $600-million terminal sits on 300 isolators, according to lead designer Arup Group Ltd. Construction was by the locally based LIMAK–GMR Joint Venture.
