Editor's note: Following are the author's opinions. Views expressed are not necessarily those of NRCA.
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.
