The Rainier Square Tower in Seattle will be a striking building. What makes it truly remarkable, though, is that its erection will take an estimated 40% less time to complete than it would with a cast-in-place reinforced concrete core. The difference? A revolutionary core of concrete-filled composite steel plate shear wall (CF- CPSW), also known as “SpeedCore.”
The tower’s design and construction team estimates that erecting the tower with a traditional reinforced concrete core would have taken 489 days. Using SpeedCore, however, the 850-ft. building’s core is expected to be completed in just 377 days, saving millions of dollars
in construction costs and allowing the owner to start collecting rent almost four months sooner.
