A plumbing vent pipe was installed too close to a form board before pouring the stem wall. The pipe was visible at the exterior of the stem wall after the form board was removed. This is a post tension slab. A metal plate was installed on the exterior frame wall over the pipe, I presume to prevent nail damage. The entire exterior/perimeter of the stem wall was coated with some type of concrete patch, which is done on all homes in this area for a more finished look. Note these photos are from a friend of mine in Phoenix. Where I live they do not coat the exterior of the stem walls, so you can see where all the tendons were patched. His question is whether this is a structural concern. When he described it to me I thought probably not. Looking at the photos the concern is another vent pipe and a corner nearby. I don't know what the builder could (or would) do about it now anyway.
