As a recovering architect, I’d take issue with the first reply. In the 12 years I was in the business we never specified where the disconnects (or units for that matter) were to be placed. Normally, the PM&E sheets are drawn up and sealed by the engineers. These are typically schematic in nature and it is left up to the trades as to actual location. [FONT=Arial]The closest I ever got to placing PM&E stuff was when I would lay out ACT grids and lights. You are right however, Most architects do not give enough attention (or space) to mechanical rooms, service areas, etc.[/FONT]
