This was an interesting read for us at Buck Robertson Contracting. We are always trying to build our framing members 24″ O.C (“on center spacing”) unless we run into Brace Walls (earthquake protection), which need to be 16 O.C. or specified by the engineer. In doing so more planning is needed to be put in up front to determine desired points of where to start your framing members layout. Truss system and floor plan design need to be taken into account as well, but with doing so makes all ducting, plumbing and electrical work easier for sub-trades by keeping runs clear of obstetrical and reducing the chance of bulk heads. If contractor is brought in at very early stages of design these things can be looked at and addressed.
