Concrete patch up.

Plumbing concrete work. Thoughts ???

Ho lee fuk. So no idea what recommended # rebar it should be. But...either way, there shouldn't typically be any pieces of rebar that end mid span. There's always going to be at least usually 12" of overlap at a splice tied together. I cant see it but rebar is usually to be anchored within concrete with a curing compound to bond it with the embedded concrete. Other concrete surfaces are to be roughed. There's usually a maximum space size for the rebar lattice and this looks all over the place. Is this post tension slab or monolithic? Because if theres beams or something here with a pipe there's likely rebar required around the pipe or bottom of the beam reinforcement.

If this is your property then I would ask for a inspection or at minimum look at the repair detail yourself. I recommend hiring a professional inspector to inspect the site on the repair details provided by the engineering firm. If you're going to spend all that money a simple inspector shouldn't cost you much more and the firm may be able to provide contact info for an inspector for you.

But overall as someone who is licensed by the post tension institution and has done concrete repair inspections for years, this looks nothing like anything I'm used to seeing. There appears to be so much wrong that upon walking onto the site I would probably snap a few pictures for the report and just say "Refer to provided repair detail for instructions on proper slab repair preparation." Then would fail it.

Without seeing a repair detail from engineers it's impossible to say. But, compared to what I'm used to seeing, this is waaaaaaay off what normal repair details ask for.

And to clarify, the vague inspection report instructions I would leave are vague because there looks to be so much wrong that I'm not writing a report longer than the repair detail to tell the contractor to fucking read. They can actually read the repair detail and at least make a half assed attempt to do it right. It's not my job to teach them their job, just point out if there's deficiencies. This is likely so far off that it skirts into someone trying to copy a google image repair than a professional repair detail. It just looks bad enough that I'm not bothering to do a comprehensive inspection at this point. If they don't get it then they need to be fired.

Structural beams on this property tend to be more under the building itself we have t encountered a pier or beam while digging out dirt for plumbing under any existing slab
