PVC conduit under drive thru?
Use PVC; that part should be in the drawings.
Also, I’m curious where you’re working at? We build a ton of these across the southeast.
FYI; do not set your 2” & 1-1/2” conduits to land on the face of the block at the cash booth; they use 1-1/2” hack channel on that wall and those conduits will not fit within the wall space. You’ll have to set them into the block an inch and the masons will need to cut around them. The “pull box” will just be a 12”x12” stainless cover on the wall with a grommet in the center.
The newer ODMB specs call for 1/2” steel power conduit to the COD, but I’ve done literally 100 of these with 3/4” PVC for power. Idk why they changed that spec to steel, but I haven’t seen it actually included in the bid drawings; it’s a separate sheet corporate EE sent out awhile back, but it’s labeled as a “vendor spec”.
If this is a remodel, we take those conduits on the surface of the building and bring them in above the ceiling grid; GC will paint to match; and again if it’s a remodel of an old mansard style roof, get your conduits in before they start the EIFS. Then let the POS guys fish their cables down the wall at the cash booth.
Also you don’t need 1-1/2” for the loop detector; 3/4” is fine. And if a remodel, you’re going to need a 3’ SDS masonry bit to get through the footer.
Your best bet is to set a handhole box in each lane and branch out to each base for data and power. It’s much easier to pull that way; you don’t want to be fighting that much cable in the base of those signs. There’s a drawing somewhere that shows that; I don’t think it’s in the bid set, but another EE addendum that was sent out that applies to all.
One more thing to add because I get this question all the time; on the IDMB, it shows two 4x4x4 JB’s and a 4” conduit sleeve on the SAM wall. That is option A & option B; whereas you either do the two JB’s, OR the 4” conduit sleeve; not both. But you do need to give them a JB or a 2gg plaster ring on the back of that wall above the two quad IG’s to bring the CAT6 in for the media players.
On the exterior D/T equipment, in all the regions I work in, they ship the CAT6 to the job site and the EC has to pull it; I assume it’s that way in all regions but you prob want to verify that. I say all of this because I’m guessing you’re new to it, and there’s a lot to know that just isn’t in the bid set. They regularly send out changes for all of the exterior and interior menu board stuff, as well as the front service counter, and they just expect that you’ve been given this information and apply it to your bid.
