National Award - $75 million to $200 million

Built in 1949 and retired in 2014 due its outdated security features and minor damage sustained during a 2001 earthquake, this historic landmark now reaches for the sky with seven brand-new floors, a new seismic system, and new steel framing that accommodates the fact that the building has moved during its 70-year lifetime.

Judge comment: “The ability to connect a new structure over an existing building, and integrating seismic and lateral bracing throughout the existing building, showcases where steel has a truly unique ability to be connected and modified into an adaptive reuse of a building that otherwise could not be brought up to current codes.” -David Horowitz, executive vice president, AECOM Tishman
