We have just started framing on our home and the framer indicates the
slab is not square on the corners. Not too bad, but still 1.5" out of
square in 2 places. The framer has the bottom plate (2x4) hanging off
the slab in a few places. He doesn't seem too worried .... should I be?

Is this common or just shoddy work on the concrete crew? Any
recommendations on what to do ... or let me know if this is normal
course and I should do nothing.

Thanks.

It is certainly common for masons to make things out of square.
Somewhat shoddy, but it happens all the time. Sometimes I think
masons should frame a house every few years just to get a taste of
what it's like to build on an out of square foundation.

Hanging plates is a common way to deal with out of squareness. That
can influence how the exterior finishes, but if it's a slab, it's not
too big a deal. I recommend you do nothing.

Thanks for the quick response - I agree, have the mason's frame a house
just to get a taste :) I appreciate the response.

I agree. It's not that big of a deal. when you say out of square 1.5", I
assume you mean one diagonal is 3" longer than the other? if it's 1.5" then
it's really only 3/4" out which is pretty damn good.

Actually - what I meant by 1.5" is that the bottom plate (2x4 lumber) is
hanging off the concrete by ~1.5". i.e, on one exterior wall, at one
corner the bottom plate is flush with the concrete slab .... but at the
Other end the bottom plate hangs off the outside roughly 1/5". Granted
this wall is long - say about 25' ... but this seems shoddy and I am not
happy with the concrete crew. Just don't know what if anything needs to
be done?!

I am thinking nothing, but will talk to the concrete guy and express my
dissatisfaction - he works on referrals only and my word of mouth isn't
going to be that great. Other than this item - the garage floor has
about a 2' circular area that is low - so water stands in that spot
about 1" deep - its right by the garage door - so wondering if they can
sand down the area so that spot will drain outside??
