SpeedCore leads the way in the American Institute of Steel Construction's Need for Speed campaign, which also includes SpeedFloor, SpeedConnection and speedier simple bridges.

Thanks to its modular heart of steel, the structure of Seattle’s 850-ft-tall skyscraper rose twice as fast as a steel frame with a leading concrete core

Cheerleaders for steel buildings with modular composite plate-steel cores have found ways to simplify the novel system for high-rises.

As predicted, the Erection Co. topped out Seattle’s 850-ft-tall Rainier Square Tower, with its radical composite steel frame dubbed “speed core,” in only 10 months.

With floors 10 and 11 of Seattle’s 58-story Rainier Square Tower under construction concurrently, crews from the Erection Co. are meeting or exceeding speed predictions for the radical composite steel frame’s steel erection, core welding and core concrete casting.

The team setting the stage in seismic Seattle for a 58-story composite steel frame calls the project “a game-changer”
