I think my framing question is solved by using cement blocks! Sorry for the errant post.
I watched a video of a large addition where the excavation was flush with the existing foundation along the back wall, so if you don't mind educating me, why does the footing need to be wider than the perimeter. (I actually though it WAS the perimeter.)You still need room to lay the footing, usually the hole for a new house has 4 to 5 ft all the way around the outside.

If the wall below grade is concrete block, the excavation on the outside does not have to be that wide unless drain tile need to be installed.
Block can be laid from the inside of the wall (and still tooled joints). It is commonly referred to as "over the wall" construction. - This method can radically reduce the problems, especially when a wider excavation can accumulate much more uncontrolled water after an overnight rain.

The depth of the hole was not discussed, as there is no way to shore up the side of the hole, I'm not getting down to nail a footing frame together against a 6 or 8 ft dirt wall with a loose dirt pile beyond that.
We have had a bank come down overnight and take out twenty ft of forms and that was with a 5 ft walkway. Glad I didn't have people in there when it happened.
