Wilson Electric was part of the Design Assist team, approximately 60 contractors and subcontractors. Construction began in 1995 and was completed for opening day March 31, 1998. The 1.3 million square foot stadium is six levels with 49,000 seats, 69 luxury suites, six party boxes and a swimming pool on 26 acres in downtown Phoenix. The 5.25 acre retractable roof is made of 9 million pounds of structural steel, and opens using two 200-horsepowered motors and four miles of cable on a pulley system. NETSIAN Technologies Group integrated all special systems including closed circuit television, access control and fire alarm. Energy-efficient controls for the retractable roof and HVAC DDC temperature controls were installed, as well as Avaya structured cabling infrastructure and ProSound Audio-Visual System. Wilson Electric's Service Division has provided preventative maintenance for the facility ever since.
