Plans for a underground fire main for Building 1 that begins at the 6" backflow preventer (off of the 8" site main) and includes approximately 120' of 6" DR18 pipe, tying into a stainless steel riser sweep terminating 1'AFF. The FDC is a yard FDC tied into the underground main. The underground is included on a single set of plans with the site private mains and building 2 underground, so I have included the comments for the entire project under both building reviews.
New Comment: I attempted to contact the plan contact with questions Monday 10/18 but never heard back. PJW Wednesday, October 20, 2021
