Rainier Square Tower is a mixed-use skyscraper currently under construction in the Metropolitan Tract of downtown Seattle, Washington. The 850-foot (260 m) tall, 58-story tower is located at Union Street between 4th and 5th Avenues adjacent to the existing Rainier Tower; it will be the second-tallest building in Seattle upon completion. The $600 million project is scheduled to be completed by 2020, and will be the tallest building constructed in the city since 1985
The tower, designed by NBBJ, features nearly 200 luxury apartment units, 750,000 square feet (70,000 m2) of office space, and 30,000 square feet (2,800 m2) of retail space. Six levels of below-grade parking can accommodate up to 1,000 vehicles. The tower has a "sloping" appearance, starting with a wide base and gradually becoming slimmer at higher floors. Early designs had the taper beginning at a higher floor, but it was lowered so as not to obscure views of the unique "pedestal" base of Minoru Yamasaki's adjacent Rainier Tower.
The tower uses a "radical" shear wall core system that used steel plates in lieu of traditional rebar and formwork between concrete elements. This method reduced the amount of time needed to erect the floors of the tower.
