In 2013, the world’s largest tunnel boring machine, Bertha, was compromised while digging a road tunnel under the city of Seattle. Mammoet came to the rescue. Working on a constricted site, over a extraction pit, the 2000-ton cutter head was lifted out, repaired and replaced using a unique ‘self-balancing’ tower gantry.
