MPC Enterprises produced over 825 pieces of precast concrete for use in the new St. Louis CITY major league soccer stadium. Construction broke ground on the 22,500-seat open air stadium in February of 2022 and the facility opened November 16, 2022.
The precast concrete, which included wall panels, stairs, risers, spandrels, beams, and flat slabs, took eight months to produce and five months to erect. The wall panels and spandrels received a trowel finish that left the precast ready for paint. The stairs had a light sandblast finish and the risers had a broom finish making both slip-resistant. Custom Helser Riser Forms were used to accommodate the many different rises and runs of the stadium.
During the erection phase, precast concrete loads had to be shuttled through an underground access tunnel with only one way traffic. That same tunnel was used by all trades. Three crawler cranes were in the stadium bowl during the erection process. One of the cranes was used to erect the supporting steel for the precast and main structure. A second crane was used to erect the precast concrete. The final crane was used to erect the canopy.
Erection of the precast concrete also included lifter patching, grouting, joint caulking, and patching of connections. |
