It's already done everywhere in Europe. Here is a typical example. http://www.scotframe.co.uk/MainlandUK/Val-U-Therm/Val-U-Therm-Buildability-Benefits.aspx http://www.scotframe.co.uk/MainlandUK/Val-U-Therm/Val-U-Ther.... No-one is willing to pay architects/engineers to design houses like airliners which have all the cables and pipes routed in CAD before hand, the margins in the industry are too low to take the time to do this. Sometimes if there is a tricky area where I am concerned that the parts won't fit I will do a reference design to be sure that I have enough space, but contractors almost never build it the way we have drawn it anyway because we haven't specified the systems which they prefer because of the kickbacks from existing relationships with their suppliers. There is nothing more annoying than doing a load of work for free which you know is pointless. I have worked on everything from individual houses to airports and even with large buildings the contractor's engineers often completely redesign the systems that have been designed by the client's engineers.
