As a GC, which materials do you let the subs purchase?
I'm going to build a house. When I worked as a construction manager for a homebuilder several years ago, we ordered the lumber, windows, doors, stairs/railings, garage doors, trim, cabinets, lighting, appliances, vanities, floors, paint, and other finishes. We let the mechanicals (elec, plumbing, HVAC) provide the wires, tubes, duct, etc. for the rough-in stuff. Any other material-management approaches anyone's taken that works well?
