If you use sound attenuation below your tile and hardwood.I've seen them used a lot in commercial buildings, especially hotels, but never in a residential setting. They certainly would make a good solid floor for residential and would greatly reduce noise transmission from floor to floor.
If you look closely you can see a bit of a rounded recess in the edge of the precast. They probably set them in place, caulk the bottom of the joint, and fill the gap with high strength grout. If there was a traditional t&g on the edges, the installers would have to be sure not to get two T’s or two G’s together ... this way the precast is omnidirectional.They don't appear to have a T&G connection?

I do not see where the IRC provides for this type of construction which suggests that the IBC governs.
Looking at the picture, i only see a strand at the bottom of the webs. So if you located the hollows and drilled there it shouldnt be a problem.I'm guessing there were a couple extra strands because we didn't notice any structural distress afterwards.
Sorry ... don’t know how to edit a reply after it is posted.I'm guessing there were a couple extra strands because we didn't notice any structural distress afterwards.
These are pre-stressed. They are cast with a bow in the center to allow them to settle level, the space between the panels is stuffed with a backing material and a top coat of concrete applied over top, because the people who can afford this type of thing in their garage/house will not accept having those beveled edges. If there is coring or drilling, they should be factory installed (precast). site modification of the panel is a huge no-no. An engineer is required on each project not just for the panel, but the wall supporting it as well.
So what are the supporting walls?
We get stamped plans and the factory turning these out sends a crew to do the installation. Our subdivision inspector actually used to do this. He is an invaluable source of information on these.Now we're cooking, so there's an engineer involved, I thought so.
So there should be an arrow saying this side up ^. Probably some paperwork for Jar to read...I would think..
Don’t understand 15M.Typical reinforcement is 2 rebar mats 15M at 12" vertical and horizontal.
Metric rebar size.Don’t understand 15M.
Metric rebar size.
Apparently this is somewhere between a #4 and #5 for you folks.
I got a shocker for you. There is also European sizes that is different than both of ours.Right ... 15 mm = 0.59” ... #5.5 rebar. So how does that work? The rebar i see has the size molded in with the ribs ... whole numbers ... surely there isn't a separate rebar mill for metric sizes.
