You're in FL and assuming the project is too, you don't have freezing issues here correct? If that is the case, why is there a dry standpipe system being specified? And what edition of NFPA 14 is adopted by the jurisdictional authority? And please clarify - you describe the construction of a hotel "at the marina", with a dock , "...located on the side of the hotel opposite the street." Is the hotel on the same parcel as the dock, or across a street from the dock and is this a public street if so? And is this 8-story building code-classified as a mid-rise or high-rise? You're providing a 1,000 gpm pump - is that because you've got an automatic water supply for the standpipe system?
Answers will be more specific pursuant to the above, but generally, the standard (14) is mute regarding shared systems between buildings and marinas. Within a structure, if there are rated separations (fire walls) that separate the shell into multiple buildings as defined by code, there are provisions in 14 for how to share a water supply and calculate the demand. Hotel/marina sharing for the AHJ to decide, but my first reaction is a hard no as you describe it. I have another idea that would be semi-shared, but I'm keeping that until I get the retainer.

From: John Irwin <[email protected]> Sent: Tuesday, July 30, 2024 12:07 PM To: [email protected] Subject: [Sprinklerforum] Dock System / Stand pipe I have a situation I have not come across before. New construction of an 8 story hotel at the marina. Plans also call for a manual dry dock hose system. This will require, one, maybe two hose valves. The dock is located on the side of the hotel opposite the street. Civil plans call for an underground run from the front of the hotel, all the way around the property, along the sea wall, to the dock. I have a stair well, with a stand pipe in it, about 20 ft from where the dock hose valves would need to be. Can I delete the manual dry hose and feed from the hotel stand pipe system? Or even directly from the fire pump would be preferable to all the underground work. Can I change the FDC sign on the front of the hotel to include the dock hose valves? "Hotel & Dock FDC" My pump is already 1000GPM. Would adding these hose valves effectively make them part of the stand pipe system? Is there any reason in NFPA 13 or 14 that I can't extend my stand pipe system out horizontally?
