Todd, I am guessing that the other model building codes are pretty similar to the IBC with respect that depending on the type of construction, the intended classification/use group (as you pointed out), and the size of the project (area and height) all play into whether 13R is a viable option. In recalling the thread that I mentioned in earlier post, I believe the subject line was 13 vs. 13R for that previous thread. If I remember correctly someone had asked about a parking garage, but then some else brought up a retail space and everything went to hell in a hand basket. One of my favorites. Sure it's not "PE vs. Layout/Design but not Engineer Technician Designer Person" quality, but up there with the greats. I may take a nostalgic look back for kicks this evening, but for now I just want get out of the office before George gets back and thinks of something for me to do. In that post, I think someone mentioned that in order to have the horizontal separation needed, a 3 or 4 hour barrier would be needed. Yikes!!!! I am thinking that if someone were to go to that length and spend that amount of money that a full 13 systems would be small taters. And that person should also be able to collect bling from the general public. I agree that it is a little unusual, but also keep in mind that the IBC (and I am sure other model codes) limit the footprint (depending on the construction type)of the structure so that this doesn't get out of hand. We (or maybe I) are speaking in terms of a residential building with parking below for the tenants to use (and maybe Aunt Ethel and Uncle Charley when they comes to visit). What is wrong with maintaining a life safety level of protection in this instance? Nuttin says I.... I don't know why if you take the same parking garage and put it beside the Residential building and put a separation between them that a full 13 system would be called for. Dat don't make sense to me unless to compensate for not needing as high a fire rating to form the separation (1 or 2 hour instead of 3 or 4 hour). Then it would make sense. Right? But I think that by the time you get to that point, your square footage might possibly put you over the limit of what the model codes says you can have for a particular construction type and still use 13R. If you get to that point then little section in 13R makes no nevermind. I don't want to even ponder mixed use at this point. Cuz I am too tired. "13 Light" - I like that. Here's to you Mr Stonington Connecticut PE sprinkler guy!!! Have a good evening.... I'm outta here.
