That's where I am now. Dimensioning this mell-of-a-hess so that the subs can install it perfectly.....all the while the installers are arguing with the walls guy and the structural people because they forgot things....like, depressing the slab for the bathroom tile, and putting in the structural walls in the wrong location. This, on a job where fraction of inches means the WORLD on a core drill for a combination waste and vent sewer riser that CANNOT offset (going up 4 floors)
