I'm having an addition put on my house with a full basement. The contractor poured the footer and is getting ready to do the foundation walls. He marked the lines for the walls, and I couldn't help but notice that one corner is cutting it very close where the block actually overhangs part of the footer (see pics below). Also note, they didn't use a form for the footer and just poured it into a trench in the dirt, so the edge is rough and some of the concrete supporting the block is just over-pour and not solid footer. It looks like only about 7" of the 12" block will be fully supported by the footer!
Is this footer going to work? Is it to code? If not, what needs to be done to fix it? Can they just dig out more to the side to add to it? Does the part of the footer, or even the whole thing, need to be replaced?
Edit More details about the addition: The addition is 15'x30', with 2 15' walls and a 30' between them. (The other 30' side ties into the existing structure.) The corner shown is the end of one of the 15' sides. About 2/3 of it will be 2 stories, including the space above the corner in question. Wood framing with 2x6 external walls will sit on top of the foundation. Greater Philadelphia, PA area.
Update Spoke to my GC, and he confirmed that his concrete subcontractor screwed up by about 6-8 inches. They will be digging the difference out today and pouring additional concrete. But the question still stands: Is this a good, code-compliant solution that won't give me trouble 10-20 years down the road?
