Stay away from this. It will come back to bite you.
I'll bet he does! Who wouldn't want someone else to
take responsibility for his mistake? So you've got a slab with around
half the bending strength specified, one that's much more likely to crack
and settle, one that no one is going to be very happy with down the road
IMHO. Why should you be the fall guy? It isn't a structural
safety issue, is it? Is there any code requirement that would demand
that it be replaced--probably not. Doesn't it boil down to 1) who pays
to correct it if it is corrected, and 2) who benefits if it is or isn't
repaired? Sounds like something for the owner and the contractor to
discuss between themselves, with you staying as far away as possible!
Now, if it were a main beam that was built 25% too shallow that would be
quite another issue.

I am looking for some suggestions in how to handle the
following situation. I received a fax from the architect stating that the
owner's representative observed the slab on grade for a pharmacy was 3"
thick in some locations. The structural drawings called for a 4" thick
slab with WWF reinforcement on compacted structural fill in accordance
with the geotechnical report. The slab was formed some time ago (they are
beginning interior finish work on the store) and now I find out about
this. The general contractor now wants me to sign off on it. My question
is "Is there some way to determine whether the 3" slab is acceptable
without ripping it out ?
Thanks for any help in trying to resolve this
