More than a decade and a half of research and development paid a huge dividend: a 58-story, 850 ft tall tower in downtown Seattle that was erected 43% faster than traditional techniques would have allowed. The Rainier Square Redevelopment was a trailblazer, employing the first use of SpeedCore - a prefabricated, modular, composite core wall system - as the tower's primary bracing system. The highly expedited construction schedule - 10 months to erect 65 levels, including seven below grade - reduced field labor, enhanced site safety, and provided a more resilient design. For these reasons and more, the project took top honors in ASCE's 2022 Outstanding Civil Engineering Achievement awards. In the bigger picture, the construction method used for the 1.4 million sq ft tower, which shares a prime location with the iconic Rainier Tower, is poised to transform high-rise construction.
