A couple of FM Global questions:
Does FM Global have any requirements for overhead doors? (such as NFPA 13: 8.4.2(3) (2013-2016), 10.3.2(3) (2019)) Does FM Global have any restrictions for private fire service mains under buildings? (such as NFPA 13: 10.4.3 (2013-2016), 6.4.3 (2019)) Can't seem to find relevant material there. Thanks in advance! Sent in anonymously for discussion.

In these cases, definitely cover your bases and make sure the AHJs for the project will accept these design approaches. NFPA 13 states the below:
