MKA is proud to announce that Rainier Square celebrated its topping-out on August 15, 2019!

This project is the first high-rise to use "SpeedCore," the Concrete-Filled Composite Plate Shear Wall (CF-CPSW) system developed as a research initiative over the last 15 years by MKA along with the Charles Pankow Foundation, AISC, Supreme Group, Purdue University, and the University at Buffalo.
The core construction consisted of 67 levels—7 below grade and 60 above. Rainier Square, towering 850 feet, has taken its place as the second tallest high-rise on Seattle's skyline.
Exceeding Expectations
A building of this size with a traditional concrete core would take a predicted 21 months to top out. The estimate for Rainier Square's topping out with the SpeedCore system was 12 months. Exceeding all expectations, the tower reached its maximum height in just 10 months thanks to the efficiency of the SpeedCore, the amazing steel fabricators, and the erection crew.
Thank you to our colleagues whose contributions and intense collaboration have taken this structural system from concept to reality!
