Anything is possible in that liberal sewer/cesspool known as Seattle. Maybe somebody moved that huge commie statue of Lenin from the Fremont District to out in front of Bertha.......
Speaking as the person who built the channel tunnel TBs as well as many others. There is something fundementaly wrong with that machine, and its operators. Not sure what kind of cutters they are using. Disc cutters should have been able to handle expected pipe & concrete.
