The eighth annual American Concrete Institute Excellence in Concrete Construction Awards recognized one Canadian and four U.S. projects, among a field of 14 in seven categories.
The program was created to honor the visions of the most creative projects in the concrete industry, while providing a platform to recognize concrete innovation, technology and excellence across the globe. To be eligible for participation, projects need to be nominated by an ACI Chapter, International Partner, or selected through self-nomination.
Entries for the 2023 ACI Excellence in Concrete Construction Awards are being accepted now through April 30, 2023.
100 Above the Park in St. Louis, Mo. took first place in High-rise Structures for its unique geometry and sloping curtain wall façade. The visionary design was achieved using a post‐tensioned concrete frame and central core to support the cantilevered floors of each tier. Kienstra Co. supplied concrete for the thirty‐six story, 316‐unit residential tower.
Second place in Flatwork went to SoFi Stadium in Inglewood, Calif., which comprises over 720,000 ft.² of decorative paving. Everything on the project was on a whole other scale, stretching decorative concrete flatwork placements to 300 yd.³ a day back-to-back while maintaining consistent surface-retarder finishes. Catalina Pacific was the concrete supplier for the project. 
The Hollywood Park NFL Media Building in Inglewood, Calif. took second place in Decorative Concrete. The building’s white glass fiber- reinforced concrete envelope with repetitive openings provide uniform views and optimal sunlight. A dark gray cast‐in‐place shotcrete base wraps the entire façade to serve as a plinth upon which the white mass above lightly sits. A&A Ready Mixed Concrete was the project’s concrete supplier. 
The Denver Water Operations Complex – Administration Building, which is constructed of post‐tensioned structural concrete, won second place in Mid-rise Structures. The exposed concrete slabs serve as the main heating and cooling element by radiating chilled water in the summer and hot water in the winter. Martin Marietta supplied 10,616 yd.³ of concrete for the project. 
Second place in Low-rise Structures went to the Brossard Aquatic Complex in Brossard, Quebec, which features cast-in-place concrete pools. A concrete story includes cast-in-place concrete stands cantilevered with respect to the main structure to give the impression that they are floating. The project was completed using close to 5,000 m³ of concrete from Lafarge Canada.
