ASU Sun Devil Stadium Expansion

  • Location: Tempe, AZ
  • Architect: Gould Evans and HNTB Architecture
  • Client: Arizona State University

Project Highlights

  • New 6,500 seat south end zone
  • Cast-in-place concrete stadia on grade
  • 3-story, 85,000 SF training and performance enhancement facility
  • Significant structural adjacencies to existing structures


In 2014, MBJ conducted a condition assessment of the entire Sun Devil stadium, followed by the design of a new 6,500-seat south end zone with associated concourses and amenities. MBJ also provided construction administration for this first phase, which saw the installation of over 500 tons of steel and 3,000 cubic yards of concrete between the 2014 and 2015 football season.

With construction of the south end zone proceeding in 2015, MBJ continued with the design of a 3-story, 85,000 square foot student athletic facility for performance enhancement and training, tucked into and expanding out from the new north end zone. Features include a second floor team auditorium, multiple “breakout” classrooms with auditorium seating, a cardio deck overlooking the expansive weight room, and a roof that also acts as the main concourse for the stadium. Significant structural hurdles included the roof, which needed to support masonry restroom buildings and passenger vehicles, a mechanical room adjacent to the head coach’s office, and a functional program that differed significantly at each level. (Phase 2 also includes a complete renovation of the west sideline and concourse with replacement of the lower bowl seating, a new club level, and new amenities, with structural design led by HNTB.)

Continuing through 2017, Phase 3 overhauls the east sideline seating and concourse area, with HNTB leading structural design and MBJ as local assist. Construction of this phase will occur during the 2017 off season, completing the project.
