NYC DOB Approves Revolutionary SpeedCore System

Since Seattle’s Rainier Tower began rising in late 2017, the construction industry has been talking about the cutting-edge project by Magnusson Klemencic Associates. Thanks to a new composite shear wall system developed by MKA, the 850-foot-tall tower rose in only 10 months—40 percent faster than a traditional concrete-cored tower. The Steel Institute of New York participated as a sponsor of the system’s research and testing to determine its stability under fire conditions.

Now, New York’s Department of Buildings has approved use of the SpeedCore system in city projects. View the letter of acceptance below:
