The new Airport Traffic Control Tower at San Francisco International Airport (SFO) was recognized as the top engineering project in the United States. In an awards ceremony held in Washington D.C. on April 19th, the American Council of Engineering Companies (ACEC) named the tower facility as the 2016 “Grand Conceptor Award Winner” for employing a cutting-edge vertical post-tensioned system, enabling the tower to remain upright and fully operational after a major earthquake.
“The new Airport Traffic Control Tower at SFO is the physical manifestation of our Partnering approach to construction projects, delivering innovative engineering solutions in an iconic design,” said Airport Director John L. Martin. “I congratulate the entire team for their achievement, and I thank the American Council of Engineering Companies for bestowing their highest national award to this project.”
Walter P. Moore, a civil engineering firm based in San Francisco, was presented with the award for employing the vertical post-tensioning solution to meet the unique structural needs. The tower is the tallest structure in the United States to employ the post-tensioning concept.
The conceptual design was created by airport master architecture firm HNTB, with the detailed design work accomplished by Fentress Architects, the design partner with Hensel Phelps on the design-build team. The resulting 221-foot-tall torch-shaped tower and offset control “cab” creates a distinctive form that sets a new design standard while being seismically sound and meeting the FAA’s strict requirements.
The facility includes office space for Federal Aviation Administration (FAA) personnel as well as passenger walkways connecting Terminals 1 and 2 both pre- and post-security. Designed to achieve LEED “Gold” status from the U.S. Green Building Council, the facility features include photovoltaic panels, natural daylight in offices and the public lobby, a roof garden, low-flow plumbing fixtures, energy-efficient heating, ventilation and cooling (HVAC) systems, programmable light-emitting diode (LED) lighting; electric vehicle charging stations, and sustainably-produced interior finish materials.
