I just checked a job estimate for some demolition items.
It's $50k to take out (4)300kVA transformers, (2)750kVA transformers, (5) Switchgear lineups and a whole lot of other stuff.
It's a separate $4,500 just to get rid of the (1)750kVA PCB transformer.
Even I didn't realize how nutty the PCB costs have gotten.
