This month, I originally had intended to provide some guidelines
explaining the process by which FM Global engineers decide whether
submitted roof systems are "Approved" or "Accepted." However, it
appears FM doesn't want to provide that type of information to
those of us who submit new/replacement/re-cover projects for
review. The FM engineer who originally had volunteered to help with
this article suddenly had his responsibilities changed and his
"time" was so limited that participation in this type of article
became impossible. It might lead one to believe FM's "Approvals"
and "Acceptance" of roof systems are more subjective than FM would
like us to know.
So lacking a clear (or any) direction, we as an industry are
left to muddle through our dealings with FM as best we can.
