HNTB Embeds Air-Traffic Control Tower in San Francisco International Airport Terminal
Air-traffic control towers are usually glimpsed from a distance. Unless your destination is San Francisco International Airport. To establish a gateway to one of the most design-centric cities in the U.S., HNTB planted the base of the tower directly inside a terminal, where the glass roof affords vertical views of the 221-foot-tall structure’s shimmering aluminum skin and cascade of glass. Not visible but even more important, posttensioned construction assures that everything will remain upright and functional during earthquakes.
