a cantilevered roof and windows to give
controllers an unobstructed view of the
airfield below. The tower façade consists
of curved metal panels and a vertical
glass band that is illuminated to colorfully glow at night.
The base of the new SFO tower includes a corridor and a secure connector
between Terminals 1 and 2, FAA office
space, and improvements to the Terminal 1 Boarding Area C entrance. The
corridor offers a glass skyligh that provides visitors with views directly up the
full height of the tower. The secure connector bridge also offers unobstructed
views of the runways, a rest area with
seating, and an adjoining yoga room.
Construction began in summer
2012, was ready for FAA equipment installation in summer 2015, and opened
in autumn 2016. Construction manager
T2 Partners, New York, selected Architectural Glass & Aluminum (AGA), Livermore, CA, as the glazing contractor.
AGA relied on Wausau's systems to
meet the aesthetic, acoustic, blast-hazard-mitigation (BHM), seismic, thermal, and other performance specifications of SFO's unique facility.
AGA technicians installed more
than 4,000 sq. ft. of Wausau's four-sided, silicone-glazed curtainwall products, including SuperWall 8250 series
