The challenge

Ц served as construction manager as part of the Mortenson | Ц | L. Keeley joint venture that built the new stadium and training complex for St Louis’s first Major League Soccer team, St Louis CITY SC. The new campus includes a 22,423-seat stadium, a 30,000 SF elite training center, three practice pitches, and a 10,000 SF retail pavilion.  The scope also required demolition of a highway overpass, rerouting and rebuilding a major road, creating a new highway exit, and building over the remains of the existing street to create a support-services, underground tunnel to the back of the stadium.

The entire site occupies 31-acres near historic Union Station and features year-round functionality with indoor and outdoor spaces and infrastructure for hosting community events. It shines as a successful example of urban infill, which inspired the St. Louis CITYSC team name. Its construction has fueled a resurgence of the Downtown West district, attracting development, generating civic pride, and heralding a new era for St. Louis

Challenge met

Sitework on CITYPARK Stadium began in March 2020, days before the COVID-19 pandemic forced workplace shutdowns around the world.  However, with careful planning and thoughtful communications, construction was able to continue, with the MAK JV and trade partners adhering to local health requirements by conducting daily check-ins, personal health audits, social distancing, masking, and additional cleaning. Safety measures helped our workforce avoid large-scale outbreaks. The project recorded more than 2.5 million craft labor work hours and the team’s performance on this project earned a feature in OSHA Success Stories. 

As the pandemic continued and design on the stadium progressed, supply chain disruptions affected material availability and created cost escalations.  As a solution to expedite as many long-lead items as possible, many materials were purchased early, prior to final design, including the structural steel. Ц’s steel fabrication division was able to place an early steel mill order, prior to the designs being 100% completed, so that it was protected against price fluctuations and shortages.  By doing so, the project saved more than $750,000. 

Ongoing communications and a comprehensive vendor surveillance process helped to ensure well-coordinated material deliveries and a schedule that allowed the team to play their inaugural match on Opening Day.
