: Is hammering rivets into a bridge the equal of conceiving of, designing and organising the necessary material to make it an actuality? Would the Hoover Damn have existed without Frank Crowe and his 'six companies' contracting enterprise? Presumably he happened along mid construction and appropriated the project?
