I have a bit complicated architectural design for a main lobby of a building.. i just want to know if a sprinkler system can be omitted in this area? see the picture..
Check your building code and NFPA 13 to see if it can be. My guess is no. There is nothing in NFPA 13 that says you can omit sprinklers when the technician feels it is too complicated to draw. This is where a good 3d design program can make all of the difference in the world.
