These drawings complement Section 07840 Firestopping Master Specification. These are the joint drawings, webpage 2 of 3. Please follow the links in the boxes above or below to get from one to the next. These drawings are intended to show where firestopping is required. The areas to be firestopped are shown cross-hatched. The idea is that the specification text shall govern what materials and certification listings are to be installed - where. The drawings also complement one another as well as the accompanying text, beneath each drawing. Another significant concept embodied in this information is that the entire use of it in a project manual is intended to ensure, or at least increase the likelihood of equality in bidding.

07840 Drawing 10

07840 Drawing 10 - Head-of-Wall Joint, 1 Hour Drywall against Q Deck, along the Flute

07840 Drawing 10: Again, heed the comments in the Master Specification Section. This firestoppping must precede the spray fireproofing, if there is to be spray fireproofing on the Q deck. Figure out how much motion there will be. Civil engineers are often overly cautious in answering such questions, to the point of physical impossibilities, which, when allowed for in construction, can add considerable and unnecessary costs. You're best off to pick and specify the exact UL or ULC listings, which fit the bill, both in terms of motion compensation and hourly fire-resistance duration. These things change all the time, as new listings continue to be added by assorted firestop manufacturers. There are innovative methods available now, which deal with the head-of-wall joint treatment. Some use proprietary tracks, which must be installed by the drywaller. Others simply rely on packing and caulking after the fact. The choice of systems must be based on your determination and quantification of the desired motion compensation as well as the hourly fire-resistance rating. Avoid the Cheech & Chong method: letting the drywall contractor do this, or letting the drywaller do part of it, like stuffing in the wool inside the flutes. Bounding must be a single responsibility for one sub trade, the firestopper, if the result is intended to meet code, rather than just to trade dollars against safety. So, pick your system, and place responsibility in Section 07840, along with all the required documentation, which makes it economically and practically unfeasible to bust up the workscope. Whatever you do use, should also be substantially identical to a penetration seal design because there are always conduits, beams and assorted other penetrants hugging the bottom of the slab above, which then penetrate the firestopped building joint. An absolute No-No should thus be to use urethane based caulking in head-of-wall joints. Urethane based caulking can survive firestop testing only in unpenetrated joints. The instant you run a cable or conduit or other thermal bridge through that joint firestop (which ALWAYS happens), enough heat can get conducted through to the other side to ignite such caulking, however seductively priced it might be. Apart from that, your bounding is thus out the window, and your liability taxed to an an undesirable extent. Hence, stick to silicone and latex based systems, that have good penetration seal coverage apart from HOW joint firestop listing coverage.

07840 Drawing 11 - Head-of-Wall Joint Firestop, 1 Hour Drywall Assembly against Q Deck, as seen against the Flute

07840 Drawing 11: This is simply a side view of Drawing 10 above. Please refer to the above comments.

07840 Drawing 12

07840 Drawing 12 - Head-of-Wall Joint Firestop, 2 Hour Drywall against Q Deck, along the Flute

 

07840 Drawing 12: Please refer to comments shown under 07840 Drawing 10 above. The only difference here is the number of layers of drywall and the resulting doubling of the hourly fire-resistance rating, from 1 to 2 hours respectively.

07840 Drawing 13

07840 Drawing 13 - Head-pf-Wall Joint Firestop, 2 Hour Drywall against Q Deck, as seen against the Flute

07840 Drawing 13: Please refer to comments shown under 07840 Drawing 12 above. The only difference here is that this is a side view of the drawing above.

07840 Drawing 14

07840 Drawing 14 - Head-of-Wall Joint Firestop - 1 Hour Drywall against Concrete Slab above

07840 Drawing 14: Please refer to comments shown under 07840 Drawing 10 above. The only difference here is that the head-of-wall joint abuts a straight concrete slab, as opposed to Q deck.

07840 Drawing 15

07840 Drawing 15 - Head-of-Wall Joint Firestop, 2 Hour Drywall against Concrete Slab above

07840 Drawing 15: Please refer to comments shown under 07840 Drawing 14 above. The only difference here is the number of layers of drywall and the resulting doubling of the hourly fire-resistance rating, from 1 to 2 hours respectively.
