One of the things I like the most about these photos is the fact that the workers who cut & drilled the walls to install the "new" cables/conduit actually made an effort to not destroy the old clippings on the wall. Sure, there's a place where it's clear they had to seam or otherwise plaster over one section, but for he most part it looks as if they kept it as-is.

This makes me happy. I've seen so many other cases where people doing their jobs totally ignore their surrounds and paint over, cut through, or destroy the things around them with nary more than a shrug and a "just doing my job".
