Still a code violation. But will it cause problems? No. Not unless an inspector gets in there and calls for it to be re done. Surprising to see that in a commercial installation.

Wanna see some ratty **** go to Key West along those docks and old buildings, stuff pulled apart everywhere, ragged cables. That aint right but there arnt any surprises or ambushes.
Contrary to some assumptions a lot of the worlds faulty work in done in commercial and done by guys with license. See a lot of beautiful DIY and some "pro" work not wired right. When I was a sprout my training lacked, my workmanship style good.

That was my point. Since there are accessible LB fittings on either side and the run is very short there wouldn't be any problems pulling wire, but a code violation is a code violation.
In addition, the rough hole through the concrete block wall should have been filled, but that's more of a poor workmanship issue.

Why didnt he just bend a 90 to go in there?

Isn't conduit galvanized? Welding zinc is something that you should avoid breathing

That would have left a lot of EMT unsupported and vulnerable to damage just hanging out in open space. A parking ramp is rough country. Kids swinging from it, etc.

Not a 90 down and through the wall. A 90 in place of the middle lb. The other lb's could have stayed. It actually looks like one of the pre bent factory 90's sold at the box stores would work if he didn't have a bender. If a standard 90 by chance won't fit, it's time to break out a hickey and make a short 90. Or change the other lb's to pulling c's. I HATE c's, but sometimes they are necessary

I think he means removing all lb's and making a 90 go straight down down one wall and through the other.

What I see is a waste of an LB

Yes, that’s what I interpreted it to mean.
Substituting a nice clean sweeping bend on the inside between the 2 lb’s would be WAY better.

Clamp it at each end of the 90.
If you're that worried about it do it in rigid pipe.

I'm talking about a 90 between top and bottom lb.

That is a common assumption, ranks with all China end wrenches slip on every bolt. I say that has at least an even chance of it being a guy in an electric truck.
parking garages don't want any exposed pipe that someone can hang off of, or tie something to. Everything is tight to the wall or ceiling. If there's a gap, it will get pulled off the wall. Two of the LBs could have been eliminated by rolling it around the corner (two 90 offsets, with a jog between them), but there are reasons that doesn't always work (like the 360 degree limit).

Shouldn't it also be on strut, and not right up on the concrete ?

huh?
who said anything about welding?
Post before mine about using conduit as exhaust pipe, but it really should have been its own post vs cluttering this thread.
Putting it on strut means it's not tight against the ceiling, and it will torn down from people hanging on it.

Yeah, Vandalism is always something to consider.
We would use IMC or rigid in areas where vandalism might be an issue. Also on strut to help with moisture and **** behind the conduit.

aww i missed that but they didnt say anything about welding and many exhaust system installs are done nowadays with clamps instead of welding...

Doubtful. It's in a parking ramp of a major hotel that I visit regularly, any construction or renovation work I've seen there has been done by legitimate contractors.

Back to the use of EMT for Exhaust pipe, IMHO, EMT is superior to what I have seen used in the past.

I use pieces of conduit for exhaust on occasion. Aftermarket does use a lot of clamps, welded too, weld is the best in some sense and used regular in repair.

How is a 90 up tight to wall and ceiling clamped at both l's any easier to hang on than that mess theres there now?
I've wired and been in plenty of parking garages over the years.
Between conduit and c.i drain lines and sprinkler lines theres plenty of stuff for people to hang on if they feel the need to.

He was thinking of turning an outside 90 and eliminating all the lb's. I don't think that thought would have occurred to me in a million years if I was doing the install. Although, if it's 12 feet off the floor and it would't put a guy over on his bends, it's not a bad idea.
Something like this:
I'm pretty sure it's the Benefield book.
It's a pretty common technique around here. Gets used for exposed runs from switches to lights pretty often, and in framing where you can't use a conduit fitting, because it'll be buried in the wall.
Was just hashing this out in the office this morning, that so many things people pay good money to 'professionals' for is just awful. Those professionals need to be beaten with a 1" gasoline hose filled with BBs. I've spent 30 years in two-way radio and am a ham, and the number of 'pro' installations that are absolute travesties is simply astounding, scary. And then there are all the comments about 'ham installs' Gimme a break before I break your lips, buddy.
Sure, every once in a while you're getting to the end & something has to be cobbled. But I've been behind lots of the same techs and see they make a career of doing 1/4-assed work.

That's where malleable 1-holes with back straps are nice... Gives you 1/4" gap. Enough to prevent debris from building up, but not enough to swing on.
Prisons are even more strict - all spaces between the GRC and the concrete surface must be caulked with a hardening epoxy. Prevents little gaps where contraband can be hidden.
