I am about to start on a project that has a somewhat similar situation that I would appreciate some feedback on. This is an existing facility and the company manufactures medical devices. There is an existing sprinkler system at the ceiling level, approximately 25 ft off the floor. The majority of the space has ceilings at around 8 ft, some hard tile, some melt-away. The sprinkler system modifications (heads below ceilings, etc) were done in house and not correctly. My charge is to come up with a design that meets Code. All of the melt-away tiles are to be replaced and rated tiles to be installed in their place. Consequently, sprinklers will be needed below the ceilings. The problem is that one large area has a ceiling which partly covers the space and the rest is open to the roof. There is no wall between the low ceiling and the deck, so it is a wide open space. My question is on the hydraulics; am I going to have to include sprinklers both at the roof and below the ceiling in my remote area? I think I am since it does somewhat mirror a cloud situation, but would appreciate some feed back. Todd G.
