Since its construction in 1970, Arrowhead Stadium has been regarded as one of the NFL’s best and loudest stadiums. In 2008, the owner, Jackson County Sports Authority, decided to upgrade rather than replace the aging stadium, a significant departure from the trend with older NFL venues. As a result, the stadium underwent an extensive renovation and expansion to provide a roomier, more fan-friendly experience. The iconic seating bowl and concrete skeleton were restored while additional amenities such as restrooms, concessions, bars, club lounge spaces and art video board displays were added.
As the structural and diagnostics engineer, we rapidly implemented a plan to assess the aging structure, identifying the type and extent of deterioration throughout the structure. We then implemented repair solutions to extend the stadium life for another 30 years. In parallel, we designed a major structural expansion, creatively minimizing the number of expansion joints in the expanded portion while respecting the joints in the existing structure.
To minimize Game Day disruption, the construction was phased, fast-tracked, and sequenced around football games.
