David Scott, foreman and owner of Bay State Piping Co., Inc., explained to me that they would be blasting out a channel (hydraulically, I believe - kind of like pumping for clams with Cy Norton) some thirty feet beneath the bed of the harbor.
Being a techno/gadget/gizmo geek, I found the equipment, as well as the whole prospect of drilling beneath the harbor, quite fascinating. I mean, who on earth invented these machines and devised the method for this kind of project?
So, plan on lower Dock Street and Memorial Wharf being in a mess for a while.
The drill's entry point.
