Editing Mountain America Stadium (section)

==Construction and upgrades==
Built in 1958, the stadium's original capacity was 30,000. The first major renovation, in 1976, substantially raised the capacity to 57,722. Seating was added to the south end zone, along with press and sky boxes. A year later, in 1977, the upper tier was completed to bring seating to 70,311. In 1988, 1,700 more seats were added. During that time the Carson Student Athlete Center was added to the south end. The building is the home of the [[Arizona State University Athletics|ASU Athletic Department]].

In 2007, engineers realized the stadium's concrete base was buckling due to rusting of structural steel supporting the foundation. Stadium designers had failed to account for the need to [[waterproofing|waterproof]] the structure when it was built, assuming that a stadium in the desert would not need [[hydrophobic concrete]]. However, they did not take into account that cleaning/maintenance crews for ASU (and later, the Cardinals) would use [[Pressure washing|pressure washers]] with chemicals, to clean the seats and rows of the stadium after every game and event. The 1958 designers had also not foreseen the stadium, designed for limited Saturdays and college events per year in what was then a small market, would become the home of an NFL team, a major college bowl game and multiple concerts by the early 2000s as [[Phoenix metropolitan area|the Valley]]'s growth exploded over the ensuing 50 years. This exposed the stadium to more water and overall structural wear than the designers had envisioned. Engineers estimated $45 million in repairs would be needed to maintain the stadium beyond 2010.<ref>{{cite news |title=Sun Devil Stadium Repairs Planned|url=http://www.azcentral.com/sports/asu/articles/0624sundevil-ON.html|newspaper=[[The Arizona Republic]]|location=Phoenix|date=June 24, 2007|access-date=December 30, 2007}}</ref>

Legislation allowed the Arizona Board of Regents to set up a district on ASU property to collect revenue from local businesses. Money from the fee would fund renovation of ASU's athletic facilities, including the stadium. It was estimated the fund would accumulate enough money to begin planning renovations within 2–5 years (2012–2015).<ref>{{cite news |title=Business Fee to Fund Sun Devil Stadium Renovation|first=Cale|last=Ottens|url=http://www.statepress.com/2010/09/26/business-fee-to-fund-sun-devil-stadium-renovation/|newspaper=[[State Press]]|location=Arizona State University|date=September 26, 2010|access-date=December 1, 2010}}</ref>

In April 2012, Sun Devil Athletics unveiled an estimated $300-million plan to renovate Sun Devil Stadium that reduced stadium capacity to the 55,000–60,000 seat range, as well as adding field turf and fabric roof shading.<ref>{{cite news|title=ASU Unveils Plans for Renovated Sun Devil Stadium|first=William|last=Boor|url=http://www.statepress.com/2012/04/04/asu-unveils-plans-for-renovated-sun-devil-stadium/|newspaper=[[State Press]]|location=Arizona State University|date=April 4, 2012|access-date=November 8, 2013|archive-date=October 5, 2013|archive-url=https://web.archive.org/web/20131005004340/http://www.statepress.com/2012/04/04/asu-unveils-plans-for-renovated-sun-devil-stadium/|url-status=dead}}</ref> An initial plan to add a roof was later scrapped to control costs. In October 2013, Sun Devil Athletics announced the removal of approximately 5,700 north endzone upper-deck seats to reduce the stadium capacity to 65,870 for the 2014 season.<ref>{{cite news |title=ASU to Demolish Upper-Deck Seating in North End Zone at Sun Devil Stadium in January|first=Jeff|last=Metcalfe|url=http://www.azcentral.com/sports/asu/articles/20131003asu-sun-devil-stadium-north-end-zone-demolition-january-2014.html|newspaper=[[The Arizona Republic]]|location=Phoenix|date=October 3, 2013|access-date=November 6, 2013}}</ref> The Cactus Bowl, which had been played in Sun Devil Stadium, was moved to nearby [[Chase Field]] in 2016 so the renovations could take place.

The renovations were originally intended to consist of three phases that would take place between football seasons, thus removing the need for the team to play one or more years at a temporary home venue. Initial plans called for the entire project to be completed in time for the 2017 season, but modifications to the renovation schedule postponed the completion date to 2019.<ref name=":0" /><ref name=":1" /><ref name="finaltouches"/> Designers for the renovation were [[HNTB|HNTB Corp.]] and Gould Evans. The construction work was handled jointley by [[Hunt Construction Group]] and Sundt Construction, Inc.<ref>{{Cite web |last=Metcalfe |first=Jeff |title=ASU completes five-year Sun Devil Stadium renovation |url=https://www.azcentral.com/story/sports/college/asu/2019/08/08/asu-completes-five-year-sun-devil-stadium-renovation/1956917001/ |access-date=2024-01-29 |website=The Arizona Republic |language=en-US}}</ref>
* Phase 1 (2015): Sections of the upper deck were removed. The bleachers behind the south end zone were replaced with a steel and concrete structure.
* Phase 2 (2016): The west side of the lower bowl and loge level was demolished and rebuilt. Construction began on an athletic facility at the north end of the stadium.
* Phase 3 (2017): Completion of the athletic facility and installation of a new video board above the north end zone.
* Phase 4 (2018): The east side of the lower bowl was rebuilt.<ref name="finaltouches">{{cite news |title=Here's What You Need to Know About Sun Devil Stadium's $307M Renovation Before Game Day|first=Rachel|last=Leingang|url=https://www.azcentral.com/story/sports/ncaaf/asu/2018/08/31/asu-sun-devil-stadium-renovation-whats-new-2018/1114168002/|newspaper=[[The Arizona Republic]]|location=Phoenix|date=August 31, 2018|access-date=September 3, 2018}}</ref>
