Top Construction Projects to be Honored November 6
By AMANDA RODGERS
ST. LOUIS, Mo. – From improving infrastructure and advancing manufacturing to creating state-of-the-art healthcare and research facilities, the general and specialty contractor finalists for the 2025 Keystone Awards are building the foundation for Missouri’s future.
The award-worthy projects span highways and bridges, airport terminals, commercial campuses, medical centers, entertainment venues, industrial plants, and critical utility systems—representing the best in construction excellence across the region.
The Construction Keystone Awards are presented annually by the Associated General Contractors of Missouri (AGCMO) to recognize outstanding achievement in construction. A panel of five expert judges selected this year’s finalists based on rigorous criteria including complexity, project management, innovation, and overall quality. Finalists will now undergo a final review phase to determine the winner in each category.
Submissions represent projects completed by AGCMO’s general contractor and specialty contractor members across 11 distinct categories. The entries compete in the Mid-America Class, which includes projects built in Missouri and eight surrounding states. All entries were submitted by AGCMO member companies based in Missouri.
Winners of the 26th Annual Keystone Awards will be announced during AGCMO’s Construction Awards Gala, scheduled for Thursday, Nov. 6 at the River City Casino & Hotel in St. Louis. The event will also spotlight achievements by specialty contractors in several categories, including the announcement of the Specialty Contractor of the Year.
“This year’s finalists showcase an incredible range of projects that are transforming how we live, work, and connect across Missouri and beyond,” said Leonard Toenjes, CAE, president of AGCMO. “From long-overdue investments in infrastructure to groundbreaking healthcare and industrial facilities, these projects are powerful indicators of a growing economy and a vibrant construction industry.”
Toenjes continued:
“Our contractors are leveraging advanced technologies, new construction methods, and collaborative teamwork to overcome challenges—whether related to workforce shortages, material sourcing, or site complexities. These finalists represent the highest levels of innovation, adaptability, and execution. They bring in high-stakes projects on time and within budget while prioritizing safety, quality, and community impact.”
“It’s also exciting to see a new generation entering our industry,” he added. “From apprentices to project engineers, young professionals are seeing the opportunity to build meaningful careers while making a lasting contribution to their communities. The talent, pride, and resilience of our workforce are truly unmatched.”
