Maybe if the pipe is rehung/replaced do those heads. Not sure what the issues would be if under a section that didn't fall. Yeah motion I'm sure was sent through the entire building during the collapse. No worse I'd think than an earthquake which can last minutes. Best I know they don't replace heads after an earthquake.
Or like Matt suggested test a couple in the adjacent part and replace all that fell. Perhaps FM might be a resource? Seems to me they'd have some experience with partial collapsed sprinklered buildings.

The collapse affected parts of 2 systems but there are 16 systems in this building. Would you make an argument that the adjoining sprinkler systems were also affected? Should it be based on the distance from the collapsed section or the sprinkler piping layout? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Chris Cahill Sent: Tuesday, June 22, 2010 4:40 PM To: [email protected] Subject: RE: Rebuilidng a sprinkler system after a partial roof collapse With the cost of heads being relatively cheap it's not even a question in my mind - replace them.

I am concerned that the operating elements on the remaining sprinkler heads have been weakened by the pipe movement during the collapse and would fail once we do the hydrostatic test on the system, causing water damage to the stock. Are there any guidelines for determining whether the remaining heads need to be replaced? (A visual inspection revealed no apparent damage to these heads.) Thanks, David Bitton, Eng.
