On Shaky Ground: Engineering Safer Skies Through Performance-Based Seismic Design

San Francisco International Airport’s (SFO) new air traffic control tower (ATCT) has been engineered to withstand extreme weather and seismic activity. Read the full article by Walter P Moore’s Rafael Sabelli and Blair Hanuschak in the 2016 Annual Showcase issue of Passenger 
Terminal World.

Distinctions of the new SFO ATCT

Tallest vertical post-tensioned self-righting seismic structure in the U.S.

First U.S. use of tuned mass dampers in a seismically controlled structure

First ATCT to employ a performance-based seismic design with vertical post-tensioning

First ATCT delivered in partnership with the local airport using a design-build delivery method

Only ATCT with a 235º unobstructed, column-free view for controllers in the cab
