yes. Or plumb first, pour concrete and then frame.What if the the plumbing runs across the framing. Can i just frame across the broken up concrete (assuming it was running across and not parallel to broken concrete) and have the plumber come in and run under framing and just back fill?
We try and mark out with the plumber and then do the demo. Catch each others mistakes and everyone stays happy.That is preferred, but if schedules don't quite synch, the framers can get in there after the concrete is cut. A lot of the time, if the plumber marks it, we will even do the concrete demo for him.
