Look at the bright side - I bet after you get the other 90% ripped out, you can get a pretty good price for the scrap copper. Then again, I don't know if they give less for it being insulated.
And as far as the power pole in the ceiling, I think I figured that one out. Did a bit of googling, and found a pic of the original owners of the building:
