Conco Takes Home International Recognition at the ACI Excellence in Concrete Construction Awards!
We’re proud to share that The Ayer in Seattle, WA, a 45-story mixed-use and residential tower earned 2nd Place in the Highrise Category at the 2025 American Concrete Institute’s Excellence in Concrete Construction Awards Gala. This award is particularly special. It’s an international competition, featuring 14 outstanding projects from 6 countries, celebrating the best concrete work around the world. The Ayer represents the innovation, precision, and collaboration that define The Conco Companies. Despite the challenges of a tight downtown site, COVID-era impacts, and a months-long regional concrete strike, our team delivered a structure that now stands as a striking addition to the Seattle skyline.
