Robust Robbins EPB for Seattle

12/12/2014

On 17.11.2014 the 6.65 m-diameter Robbins TBM EPB began its journey south into the city of Seattle, Washington, USA. The machine, for contractor JCM North Link LLC (a JV of Jay Dee, Coluccio, and Michels) is excavating for the North Link Project, which is an extension of Seattle’s light rail system. The project required twin 5.8 km tunnels through glacial till and sand. JCM utilized a refurbished Hitachi Zosen machine in its fleet for the first tunnel, which launched in summer 2014, and the Robbins EPB for the second. This isn’t the Robbins machine’s first project; prior to North Link, it bored mixed ground tunnels for Singapore’s Downtown Line. Read the press release and us/42 for tunnelbuilder archive.
