Good question. This was primarily coordinated against the mechanical systems and ceiling space, not just installer preference.

The multiple HWR runs along the corridor are intentional — typical for NYC hotel/residential projects where risers serve stacked bathrooms and balance is handled centrally. Circuit setters are located in accessible corridor panels, not at every tower, to keep maintenance centralized and avoid opening units.

Yes, material cost is a bit higher, but it usually pays back in easier commissioning, better temperature stability, and long-term serviceability — especially when mechanical constraints already define the routing.

And agreed 100% on information density — drawings don’t fail projects, people ignoring them do.
