I do feel bad about not getting a second post for January. I had a slight delay due to the birth of my first child. My little girl weighed in at 6lb 11oz and made it into this world 13 days before her due date, which coincidentally was today. I will try to make up for the lapse in posting with two pictures in one post. (Yes I know, it is cheating when it shows the same thing.)
As the title hints, the corner of this wall is not actually bearing on the slab. Since this corner is at a shearwall (hopefully the hold down anchor was installed after this visit), at some point during its life this stud pack will see a compression load. Will this cause the building to fail? Most likely not. It will cause the interior gypsum board to buckle. That would sure be a mess to clean up.
A second picture below better indicates the true gap between the sill plate and the slab. You can also see separation between some studs and the sill plate. If someone were to tighten the anchor bolts to cinch the sill plate to the slab, more separation could occur, which does not correct the problem. You could fill the gap with an epoxy grout. This building uses prefabricated walls which should be fabricated to the correct height. If you fill the gap, what happens at the top of the wall?
