Kinda depends. I've been involved in projects that have handled it different ways.
If all structure is noncombustible, and the owner agrees there will be no storage of any kind, and the AHJ trusts the owner to abide by that (now and potentially forever), and the AHJ is otherwise on-board, then the pendent sprinklers have been left in their original locations. As further TI is done, that section of the system is brought up to standard. But most of the projects like this that I've been involved with have required the entire system be brought up to standard before any occupancy occurs. If this is the case, look to see if the roof structure has steel beams or other deep obstructions that may require adding a line of sprinklers to one side or the other. Start by calling your AHJ.

I’m working with a General Contractor who removed the drop ceiling in an old Sears store. They are doing a T.I. for approx 1/3 of the space making it into a medical office, the remaining 2/3 will remain an empty shell. Now that the ceiling is gone the sprinklers are 6-8 ft below the roof deck. What is typical to protect an empty shell in this situation? Likely a ceiling will be reinstalled when the space gets reoccupied so it seems a little wasteful to relocate the sprinklers up to within 12” of the roof deck to protect an empty non combustible structure. _________________________________________________________ SprinklerForum mailing list: https://lists.firesprinkler.org/list/sprinklerforum.lists.firesprinkler.org To unsubscribe send an email to sprinklerforum-le...@lists.firesprinkler.org _________________________________________________________ SprinklerForum mailing list: https://lists.firesprinkler.org/list/sprinklerforum.lists.firesprinkler.org To unsubscribe send an email to sprinklerforum-le...@lists.firesprinkler.org
