    Firewalls

    Unless I am mistaken, I don't believe the IBC dictates separate systems and I know that NFPA does not. The IBC directs you to which type of system is required dependent on occupancy, size and construction type. That is it. Penetrations through fire walls would just require proper materials and...

    Sprinkler Systems not compliant with Building Code

    Travis, I guess I shouldn't have said dental office but "dental complex" with multiple tenants . But yes it exceeds the sf stated. I guess the reason why I ask the question is because in the event of a personal injury lawsuit. They do not care whether the AHJ told you to do something or not...

    Sprinkler Systems not compliant with Building Code

    What do you typically do when you have an AHJ asking for a sprinkler system in a building that is not compliant with the code? We have a two level dental office that is VB construction that has a frontage increase. According to the IBC this building requires a NFPA 13 system. The AHJ is saying...

    Attic System Design

    No, I am still using Attic heads. I have BB heads at the peaks, SD heads at the outside HIPs and AP head covering the interior of the hips. Each area oh AP heads is less than 3000 sf and separated from another area of AP heads by at least 15 feet. I also have AP heads in the dormers as well.

    Attic System Design

    NewtonFP, I changed my design completely and now have no HIP sprinklers at all in this project. I also have made sure that everything slopes back to the riser on one end and 2 drum drip drains located in the center and remote wing of the building. I typically like to get my calculations and...

    Attic System Design

    Thank you for all of the replies. I had a long talk with the TYCO technical department to make sure I am designing the system within spec and just as Travis stated, I was incorrectly using the AP heads and I had to scrap my design (for the 3rd time.) The good news is that I redesigned the system...

    Attic System Design

    Please see attached PDF for reference. I am having a heck of a time getting this system to work and I have ran out of ideas so I figured I would come here and see if any of you can see an option that I may be missing. This is an assisted living center with a NFPA 13 system. It is fed from a...

    Flexible couplings on CPVC passing through fire walls

    It is a seismic design Category D. Seismic does apply. I am just not aware of a place even in 9.3 that requires flexible couplings on either side of a fire rated wall in type V-A construction. It has a requirement for concrete or masonry walls. I feel like this is just something the AHJ is...

    Flexible couplings on CPVC passing through fire walls

    I have an AHJ that has stated the following in his review letter: "Since fire stopping is required when the pipe passes through the fire rated wall assembly. The piping passing through a fire rated assembly shall be provided with flexible couplings within 1 ft of each side of the wall." I asked...

    Design ideas for a NFPA 13 Residential Occupancy

    stookfpe you would be correct. there are two levels of parking that are Group S-2, I-A Construction with one below grade. Then there are 4 levels of apartments on top of it that are group R-2, V-A Construction. Due to the building being in an urban location, adjacent buildings are too close for...

    Design ideas for a NFPA 13 Residential Occupancy

    None of them even get close. I think the largest one has 500 sq ft. and because of the architectural design there are 4-5 heads in those areas. I actually went through and ran a bunch of calcs and it seems I am able to get them all to work. More 1 1/2" on branch lines than we usually like on...

    Design ideas for a NFPA 13 Residential Occupancy

    Travis, thanks for the tips on that. I didn't even think to use a small room approach for the area of coverage since my mind is focused on the .15 density. I will try that approach this morning as I try a new round of calcs. If that doesn't work I may be forced to run a loop on each floor...

    Design ideas for a NFPA 13 Residential Occupancy

    I am running into some issues on a somewhat unique design for an apartment complex in SLC. Due to the close proximity of adjacent buildings in the area. The builder cannot provide FD access within 150' of all portions of the structure per the IFC. The AHJ has requested, as an alternate means of...

    Advice on locations of drum drip for a dry-loop system

    In a dry system you have to slope the mains and branch lines to a point where it can be drained. Really, your drum drips could be anywhere on that plan as long as the pipes are sloped to those areas.

    Combined System Calculation Basics

    Correct, you do not have to add the sprinkler system demand to the standpipe demand. The only caveat being that if the flow demand for your sprinkler system is higher than that of your standpipe you must use the sprinkler demand value in your calculations instead. For your second question...

    Design Areas for a Hotel

    Most demanding is what I was referring to when I mentioned my remote area. I was just confused on whether I needed to calc. the different hazard classifications separately. I will just do one calc. there instead. Also yes, I plan on using the QR reduction with 12'-6" ceilings down to 1023.75 Sq. ft.

    Design Areas for a Hotel

    I'm designing a NFPA 13 system in a 6 story hotel. Level one contains the lobby, kitchen, offices, exercise rooms, mechanical rooms, etc.. On the East end of the building will be shell coverage for future restaurants/fast food joints. Levels 2-6 will be guestrooms. I will be performing the...

    Tenting CPVC Pipe

    Does anybody have a .dwg of a detail for tenting CPVC pipe or even a .pdf I could mimic myself?

    NICET Tests for Certification

    Can anyone recommend me a website or company that gives thorough instruction for all levels of NICET Certification For Water based Systems layout. I've been in the industry for almost 5 years now and I'm wanting to do Levels 1-3 over the next 6 months to a year.

    Properties of Glycerine

    Thanks, So can someone let me know if the number that I use in the calc program for the fluid viscosity & density should be the number at the lowest temperature the solution is rated for?
