It sounds like they're doing a re-hab of a 100 year old apartment building. Best way to approach it would be to completely gut the building right down to bare studs and start over from there. The mechanicals like plumbing,electrical, & heating would be ancient. Building codes in almost any major city would require that all the old stuff be removed & everything updated to meet current code.
Phew ... i hear you about retrofitting with copper on the drain lines. I had to pipe up an upstairs bathroom with cast iron drain line back in the mid-90's. That stuff is uncommonly difficult to work with !
I can see why it evolved from steel & iron pipes to copper. By the late 90's they had transitioned from copper to everything plastic in this area. Plastic is much faster to install and works better than everything that came before it.
@ Burly .... If it was an old steam boiler they might have still been using the old cast iron radiators in the building. I don't know if it still holds true, but at one time there they were in demand just like the old clawfoot tubs were. It's a maybe .....
