They don't. Op fabricated the story, as pretty much anyone in the Navy would confirm for you.

Source: several relatives in the navy working on ships, also have dealt with the contractors in question that run cable. Contractors absolutely do not get to determine the route cabling takes. There are endless reasons that would be insanity starting with basic security of the ship. Do you think random contractor X gets to loop cable through the reactor room because it'll make him a bit more money?

Yeah… I’ve heard a lot of stories about shipyard dysfunction from friends and relatives, but it’s nothing so exciting. It’s mostly poor planning that results in expensive waste and slowdowns.
