The ATCT is 332 feet high and is attached to a three story, approximately 20,000 square foot base building.

The ATCT consists of twenty levels. The facility is protected throughout by automatic sprinkler systems.

Most of the building is protected by wet pipe type systems with the exceptions of the TRACON computer rooms and tower cab, which are protected by four separate double interlock pre-action sprinkler systems.

Automatic wet pipe Class I standpipes are provided in each stair in the tower and base building for a total of four. The tower standpipes extend to the top of each stairwell, Level 19. An analog addressable fire alarm system protects the entire facility. The fire alarm system consists of complete smoke detection throughout the tower and detection in the base building common areas, electrical, mechanical and storage areas. Smoke detection is also provided in all double interlock pre-action system areas to actuate the release of the sprinkler valve.
