    Is a synchronized double-leaf accessible?

    I'd be good with this. Verify that the opening force required is less than 15lbs per A117.1-17 Sec. 404.2.6.

    Riser room Knox box ?

    Have you called said FM and explained that there is no locking mechanism on the door? IMHO, this is what happens when someone uses a checklist. A lapse in common sense.

    Changing Table Millwork

    I agree with Ron. A117.1 Sec. 902.2 requires that the clear floor space for a work surface be by forward approach. Thus, you need to lower to 34-inches (Sec. 902.4) and remove the built-in lower cabinets.

    CondoHotels R1 or R2

    Agreed. May be impacted by zoning/planning codes, but not building codes. Condos are not limited to residential uses either - I've had a warehouse building split into condos. Allowed for contractors, small businesses, etc. to have a small office/storefront and warehouse space. Worked quite...

    CondoHotels R1 or R2

    Condo's do not exist as it relates to the IBC. Condominium is a term that relates to the ownership of a building. If it is short term, transient guests, then it is a Group R-1.

    CondoHotels R1 or R2

    What exactly are you referring to? Are you referring to timeshares and short-term rentals that are structured as condominiums for ownership purposes?

    Central Vacuum Systems in SFR/Dwelling Units

    For new construction, I think that comes down to the timing of the framing inspection. We communicate that the framing inspection is immediately prior to insulation, once all electrical, including low voltage (speakers, data, etc.), and other trades are done. In the case indicated, the central...

    After a building structure fire, what's the process?

    Do you have a Fire Marshal, or is the BO and FM one person? BO should not make the call regarding demolition unless there is an immediate hazard, with the structure being an unsafe condition under IBC 116.1. The BO can order demolition under Sec. 116, but would typically order the building...

    Plywood over metal decking?

    I'm not sure why they are required to be rated per the OP. Perhaps incidental use (Sec. 509).

    Plywood over metal decking?

    Sounds like you need to work with both your architect and structural engineer to get the design completed.

    Plywood over metal decking?

    Likely a gypsum ceiling.

    Plywood over metal decking?

    Correct, not a roof.

    Plywood over metal decking?

    There are thousands of options. What is supporting the metal decking? Joists?

    Plywood over metal decking?

    Plywood is not permitted in Type II-B. Does not meet an exception in Sec. 603.1. 2021 IBC 602.2 Types I and II Types I and II construction are those types of construction in which the building elements specified in Table 601 are of noncombustible materials, except as permitted in Section 603...

    Plywood over metal decking?

    Also, metal decking generally has no fire-resistance rating. You'll need to pick an assembly - likely something with gypsum board, concrete, etc.

    Plywood over metal decking?

    What type of construction is this? Type I or II would not allow for the use of plywood per Sec. 603.

    2024 IECC

    Just sat through the three days of appeal hearings. Thankfully they all took less than the full day. Appellants presented well, but we will see how the Appeals Board makes their recommendation, and ultimately how the Board of Directors decides to proceed.

    R408.6 Clarification

    Having started my career in the geotechnical and SI world and progressed onto being a BO, I am in agreement. Geotech reports are structured as recommendations because they are often pre-design investigations. Unfortunately, I will acknowledge that many projects I've seen have had the geo...

    Introduction and quick question

    Plus, these thin-film intumescent products must be maintained (i.e. damage such as scratches, dings, etc. are a problem) and often cannot be exposed to moisture/humidity, UV light, or other degrading elements. This can be further complicated if the manufacturer does not permit further coatings...

    Fire rated interior walls at roof

    Following Exception #4, you can just go with any 5/8" Type X. I would presume that you'd use the same gyp as that used on the walls just for simplicity. "...the roof is protected with 5/8-inch (15.9 mm) Type X gypsum board directly beneath the underside of the roof sheathing or deck, supported...

    Fire rated interior walls at roof

    Which Exception to 706.6 are you considering? Read exceptions #2-4, they tell you exactly what to do. 2. Two-hour fire-resistance-rated walls shall be permitted to terminate at the underside of the roof sheathing, deck or slab, provided that: 2.1 The lower roof assembly within 4 feet (1220 mm)...

    Introduction and quick question

    UL / UL(C) is not required. UL is just one of the many testing/accreditation agencies. While I do not have the utmost confidence in a number of ICC-ES reports I have seen, the code requires testing per ASTM E119 or UL 263. It is up to the code official if the testing/accreditation agency (UL...

    Introduction and quick question

    Correct. And being both certified to and having done SI on thin-film intumescent materials, I am confounded on how the testing would be done. Following AWCI Tech Manual 12-B, the testing apparatus only work with ferrous substrate. I am positive that there are other means and methods for testing...
