Yikes. I made a pretty large amount of money in the mid 2000’s at a military base cleaning up messes like that. They were getting ready to destroy some munitions that contained a nerve agent. There was a huge build up and staffing on the base which had been largely shuttered for years. I was called out by what turned out to be one of the main logistical offices there. This was mostly non military contractors. There were dozens of offices spread throughout the base. Each one was a sub contractor. They sent me a fifty page pdf on what they wanted done but when I got there that pdf turned out to be a fantasy. That closet was a rats nest of over lapping cables and dead equipment. There was even a still functioning(sorta) token ring network in there. I spent nearly a week redoing that closet cleaning up and throwing away dead equipment. I also spent quite a bit of time redoing the documentation and taking photos for the people at their main office. When I got done I sent in a bill and one of the people at that office brought me a book with the federal pay scales in it. I resubmitted my low four figure bill as a low five figure bill and I was off to the races. They liked the job I did and I ended up cleaning up a large amount of those offices network closets. Its amazing how many orgs out there that have garbage like that in their back office. It was good money and from it I learned that a lot of government type work isn’t done at by the lowest bidder.
