Its not codified. You might explain to the architect that if you run lines parallel to primary and secondary structure that you're left with having to connect either to the deck or substructure, or else trapezing most of your line hangers. Suggest to him or her that a meeting be held with the structural engineer to sort out the potential impacts of doing it the way that they have requested. If this is a design-build submittal, then unless it was specified that way you are entitled to the most efficient means and methods available t perform the work so long as it is per applicable codes. If, after all is said and done they still want the lines running parallel to structure, then hit them with an appropriate additional services change request and work it out with the structural engineer.
