The GC actually showed up with all 3 of his workers on Friday, and he stayed, going through the punch list with me. Shoddy work, done in his absence, was addressed. While he did have one worker "buff out" the scratches in my marble, I told him that it wasn't enough, I have barely used the sink/counter and certainly not the shower yet (custom door is to be installed this week). I asked him to call a marble store/specialist, which he did, and someone came out and took care of it. It looks a LOT better, but if one knows to look closely, one can see the scratches.
