    that triangle is a planned mechanical chase.

    A shower in a 2nd bathroom in a Type B unit.

    FYI, from my AHJ... In Type B, Option A units all restroom fixtures are required to comply with the requirements for Option A per ANSI A117.1 (2009) Section 1004.11.3.1 to the extent described in the subsections. The shower in the smaller restroom would be required to be 36”x36” clear as it is...

    A shower in a 2nd bathroom in a Type B unit.

    The layout illustrated below is a Type B unit. The master bathroom is an 'Option A' bathroom. The smaller bathroom, as I understand it, also has to be an 'Option A' bathroom. Is that truncated shower in the smaller bathroom, allowed? Or does that need a 36"x36" clear per 1004.11.3.1.3.3, as...

    Creating a 1-hr floor from an exiting floor without adding a layer above the joists.

    Creating a 1-hr floor from an exiting floor without adding a layer above the joists.

    I think http://productspec.ul.com/document.php?id=BXUV.M537 is the ticket. I think we can achieve a 50 STC based on the following NRC report: http://www.primaryacoustics.com/images/ir766.pdf Thanks.

    Creating a 1-hr floor from an exiting floor without adding a layer above the joists.

    I need to create a 1hr floor between a new dwelling unit and an existing unit. The existing floor is.. tile/carpet 1/2 plywood sub floor 2x10 and 2x12 wood joists. Want to do something like the following... http://productspec.ul.com/document.php?id=BXUV.L201...

    Exposed joists in a 1/2hr rated corridor.

    @RLGA , can you tell me where this concept is called out specifically in the code? Would like to educate myself. Thanks, Ryan

    What load factor do you use for Restrooms?

    lord have mercy on our souls. :)

    What load factor do you use for Restrooms?

    Let's say the main occupancy of the building is a (Airport terminal - Baggage claim) which is at (20 gross/occupant). Do I then need to use a (20 gross/occupant) for the restroom areas that serve that Baggage claim? Seems high.

    What load factor do you use for Restrooms?

    What load factor do you use for Restrooms? I have in the past, used a zero load factor for these--categorizing them as circulation. My AHJ hasn't seem to have a problem with that.

    Exposed joists in a 1/2hr rated corridor.

    For those curious, with the help of XC engineering, on p24-34 are the calcs to determine the fire rating of exposed wood joists and plywood. Sheet A800, has the following detail. Revit files here. All open source. Cheers. about OpeningDesign: http://openingdesign.com/about/

    Stair structure at VB and 1B

    Thanks Guys. In some AHJs it looks like the stairs themselves can be wood. https://www.woodworks.org/experttip/construction-material-requirements-framing-stairs-landings-wood-frame-structures-fire-resistance-rated-assembly-required/

    Stair structure at VB and 1B

    We have a Type VB (R-2) over a Type 1B (S-2) basement. We're looking to do the stairs towers with studs. I would imagine on the VB levels we can do wood studs. I assume we have to use metal studs at the S-2 level, correct? Or could we use wood studs here, as well? Thanks, Ryan

    What constitutes "floor area being ventilated" in a typical multifamily unit ?

    For the following excerpt, what constitutes "floor area being ventilated" in a typical multi-family unit? 402.2 Ventilation Area Required The minimum openable area to the outdoors shall be 4 percent of the floor area being ventilated. Would all the rooms in the unit be considered the 'floor...

    Is an 'opening' that has the same rating as the wall, really an 'opening'?

    Is it possible to have 'openings' in a double fire wall right at the property line, if the fire doors in the walls have the same rating as the wall itself? I guess I understood if the 'opening' has the same rating as the wall itself, its not really considered an opening as defined per 705.8...

    A fire area that cross multiple property boundaries?

    Is there any means in the code to have (1) fire area cross multiple property boundaries? Or do you need a firewall at each property boundary? And if a firewall is required, possible to have fire rated doors in the firewall if 706.2 Structural Stability is addressed. --- Specific question...

    Thank you kindly for the explanation. I'm using 510.4 Parking Beneath Group R to realize a 2hr between the VB and the 1B

    Combustible foam on exterior wall/roof near property line

    In the scenario below, possible to use EPS or Polyiso on the roof? I assume it is if it meets 2603.6 Roofing Possible to use EIFS on that 1st floor wall? I assume it is because of 2603.4 Thermal Barrier. That is, the concrete acts as the the 'thermal barrier'.

    Noncombustible wall behind cookline

    I have worked on Type VB restaurants with full sprinklers. I've heard a number of times, through various sources, that the wall behind the cookline needs to be non-combustible. It makes sense, but can anyone point me to the code that calls this out specifically. I'd just like to educated...

    Exposed joists in a 1/2hr rated corridor.

    Per TABLE 722.6.2(1) TIME ASSIGNED TO WALLBOARD MEMBRANES, it looks like we can go with (2) layers of 19/32-inch wood structural panel bonded with exterior glue as well, to achieve that 30 minute. That is, assuming exposed heavy timber will work for the AHJ.
