由建筑师NBBJ设计的混合用途塔与结构工程师Magnasson Klemencic Associates（MKA）设计，是一个850-ft-tall “proof of concept” for a new high-rise framing systemexpected to take 40% less time to build than a reinforced concrete core surrounded by a steel perimeter frame. TEC predicts superstructure work will take about a year.
在租赁Crutcher Lewis建造的塔楼，具有复合钢框架，剪切壁芯包括由交叉钢板壁的模块化夹层系统，底座充满混凝土。钢板用作永久性模板，没有加强钢。
该项目被称为潜在的游戏更换者，在高层建筑竞技场密切关注，特别是MKA。该公司的办事处在32岁nd邻近的雷尼尔塔楼，a40-story building overlooking Rainier Square。
“Rainier Square brings together my insatiable search for ‘better,’ passion for research and development and intense collaboration with the entire design and construction team to create a breakthrough in how tall buildings are constructed,” says Ron Klemencic, MKA’s chairman and CEO, the 2018 ENR Award of Excellence winner and the mastermind behind the structural design of Rainier Square Tower.
