Good points Skyler but it is worth mentioning that the decisions you mentions (13 vs 13r) etc. are subject to Geography and Jurisdiction. In Florida for instance, anything less than 50 sprinklers IS designed solely by the Sprinkler Contractor and we are responsible for answering that question. You can hire an engineer if you want too, but of course on smaller projects the additional cost can cost you the job.

It is not a fire sprinkler contractor's job to decide where sprinklers are required, and/or which standard is applicable (NFPA 13/13R). I know we all probably do this, but we really shouldn't. I would bet over half of contractors don't know half as much as they should about this subject (me included; and I think I know a lot about it). Long story: There are so many caveats to the Building Code, which trigger different requirements for this, which are different in each year of the codes/standards, and often different between jurisdictions. We don't know (and I find that it often isn't listed anywhere in the prints) if the Architect used a building code tradeoff (larger building area, lower fire ratings, longer egress distance, etc) that would automatically trigger the requirement of a NFPA 13 system throughout (not 13R, even though it may be less than 4 story residential). It could be that the building is close enough to another adjacent building that it requires a NFPA 13 system, or a rated exterior wall (which we wouldn't know the option they selected). There could be separated occupancies (with firewalls), mixed occupancies, or accessory occupancies, all of which may require a different approach/NFPA standard to be applied. The building mentioned may or may not be a "podium building" (IBC 510.2). Chapter 9 of the IBC may, or may not, have minimum requirements for sprinklers based solely on occupancy. This is just a few of the things that I can think of off the top of my head. I'm sure I'm missing some, and there are too many specific situations to list here: it would be a novel (like a building code). Long story short: don't take on the liability by quoting sprinklers in some areas, not in others, or with NFPA 13 in some areas and/or NFPA 13R in others/throughout, when you really don't know what you are doing. What I would do: call the Architect. Get it from them (in writing) where sprinklers are required and if it is required to be designed per NFPA 13 or NFPA 13R. It is best to do this early on in the bidding process, and try to get it sent in an addenda so that your competition bids it the same way you do. Of course, I have done this, and my competition beats me by still bidding it incorrectly and against the addenda, and no one realizes that the sprinkler system is installed incorrectly, except me, when I walk through the building a year later. That's life in this business. My $0.02, that no one asked for, Skyler Bilbo 1700 S.
