wet setting rebar
(OP)
This thread, thread507-244716: Wet sticking foundation dowels has some very strong language against wet-setting rebar. Can anyone explain why this is such a bad idea? This thread talks mainly about rebar in retaining walls and foundations. What about dowels from the foundation wall into an 8" CMU wall? Is it ok to wet set these dowels?

There's no good reason to do it and many reasons not to.

Maybe most importantly, and someone I think mentioned this, is you lose control over the exact positioning of the vertical rebar in the CMU wall. By design you need these at very specific spacings and in the center of your wall (or whatever your design calls for).
I'm piling on here with the others, don't do it, you could have a big headache down the road with RFI's, field fixes, etc, etc. I actually had a nightmare of a job with misplaced rebar that I had almost shut out of my memory!
Is the GC pressuring you on this? I would be really careful with them if that is the case, this is sloppy practice at best...

ACI 318 7.5.1 - Reinforcement including tendons, and post-tensioning ducts shall be accurately placed and adequately supported before concrete is placed, and shall be secured against displacement within tolerances permitted in 7.5.2.
And,
IBC 2006 1907.5 (in part) Reinforcement shall be accurately placed and adequately supported before concrete is placed.
ACI 530/TMS 402 does not cover this application (since it is the CIP concrete part of the job.)

I am not so concern about wet sticking dowels if they are only required to transfer shear force.
