bracing. i asked for bracing at endsand elbows of mains in the 12,000 sq. ft. design area. The bracing was only to be lateral bracing within 6 ft of these mentioned points. If this request is unreasonable and not-standard practice for a head replacement, then I will CHANGE my mind and the request.
I don't know if the sprinklers are different, but I bet they are. Outgoing sprinklers are from 1993 or so. That was another of my requests: that they provide the SIN for the sprinkler. The sprinkler contractor is a well known name. so they know how they want to play this game. Design includes minor density changes-- in some places up, in some places down, mostly the same. I am sure the area of coverage has changed, unless military did 3,000 square ft design areas back in the early 90's. they apparently were not E/Q bracing then. scot deal excelsior fire On Fri, May 8, 2009 at 9:53 PM, Scott A.
