Phoenix-Mesa Gateway Airport has experienced increased air traffic in recent years, and with plans to expand the airfield, it was necessary to build a taller, state-of-the-art air traffic control tower (ATCT). The new structure meets all current Federal Aviation Administration (FAA) criteria and replaces the original tower constructed in 1968 when the site was an Air Force base. The 194-ft-tall ATCT includes a 500 ft~2 control cab with room for eight controller positions. The lower tower shaft is unoccupied, accommodating vertical circulation (stair and elevator tower) and various mechanical, electrical, communications, fire protection, and navigational aids utility risers. The ground floor level houses FAA electronic equipment and storage rooms, the main mechanical and electrical service entrances, the entry vestibule, and the elevator lobby. The tower's seismically resistant, 12-sided precast concrete shaft is composed of precast concrete panels with integral color and a medium sand-blasted finish. |
