The San Francisco International Airports new $102 million control tower was honored as the top engineering project in the state of California for 2015. The construction project won the Golden State Award, issued by the American Council of Engineering Companies. The council stated that the award recognizes the towers innovative and collaborative design and construction. The new tower is the tallest structure in the US employing a vertical post tension system, allowing the tower to remain standing and operational in the event of a major earthquake. The towers conception and design was created by the architecture firm of HNTB. The 221 foot tall tower creates a distinctive form that sets new design standards and seismically sound requirements. The facility includes office space and passenger walkways connecting Terminals 1 and 2.
