Thats crazy Louder. I always have to make my own overlays/mark up every unit drawing with whats missing. Check out all the missing dimensions from this architect on the unit plans.. anything color is by me. I didnt put the HVAC/ventilation openings on my drawings bc every unit is the same ROs thankfully. Every single unit type is like this...also note that this jackleg drew 2x4 wet walls everywhere. No excuse for that. 3in drain does not fit in 3.5in walls. For a couple reasons, but you know that. We didnt do the wet walls in the bathroom like the plans show either.. i get that changed now on every job. Just make that section of the partywall 2x6...eliminates prerock, pregyp,preinsulation and having to stagger studs. Also saves lumber.
The only overlays we ever get laid into a drawing is sometimes the HVAC is overlayed in our truss drawings, or sometimes drains are overlayed in truss drawings but never both... and only the best companies do that (Trussway/PBS) I think now they are all just Professional Builders Supply, they bought out Trussways plants. They are by far the best truss company IMO. I have never, ever seen "same sheet" overlays except made after the fact by the GC or subs like me usually in BlueBeam.
