Ground Vibration Control from Explosives Demolition of the Kosciuszko Bridge

The project involved designing and building the new eastbound structures of Interstate 278 over the Newtown Creek from Brooklyn to Queens, New York City, and the subsequent explosives felling of the existing Kosciuszko Bridge. The explosive demolition of the old Kosciuszko Bridge included 10 steel trusses on the Brooklyn approach and 10 steel trusses on the Queens approach. This presentation discusses the methods and procedures that were developed to protect third-party buildings, buried gas transmission pipelines, the Long Island Railroad, the Historical Old Calvary Cemetery and the new K-Bridges. During the explosive demolition on October 1, 2017, SSI used 52 seismographs at adjacent structures to monitor vibrations. The conclusion of the presentation will include a video compilation of Controlled Demolition, Inc. (CDI) successful explosives felling of the 3,104’ long, 20-span, structural steel, iconic Kosciuszko Bridge.
