What do you recommend as the best route when routing fire sprinkler branch pipe for projects with open-web joists?
Advantages (to me) to routing within joists can be higher ceiling elevations, potentially avoiding conflicts with ducts or other systems, and potentially allowing higher clearances below the pipe for vehicles or moving equipment.
Disadvantages (to me) seem to include the difficulty of getting the pipe up and into the joist (depending upon the length of the pipe and the opening size in joists), potentially mis-aligning joists that can't allow a straight run, and potentially running into solid girders if all of the structure isn't open-webbed.
