I have a proposal to pour a stem wall footing ontop of an existing footing.
The prior contractors who did the footing poured the foundation out of
square and height.....some of it by 3" I was told.....
Do not know yet.
They put cinder block ontop and did not fill the cells yet, and got kicked
off the job.
My task is to come in and pour a new concrete stem wall ontop of the old
grade level footing.
It is wider that the building line thus I cannot put stakes in the gound
either.
I could drill holes in the footing and put steel stakes in but what a pain
in the @$&*()%^%
I could put wood stakes outside the footing and then somehow hang forms....
I am not sure which way to go............
All I know is that it is a mess.

I don't know what you are using for forms which will make a huge
difference. 2x4 backed forms are typical. You want the footing
to be able to pin the forms. I don't understand your comment
about not being able to drive stakes. Footings by definition
are wider than the stem walls. If you use snap ties, they will
pretty much self balance. Ellis makes another system that nails a
steel strap to the footing that holds 3/4 sheets with no backers.

type forms.

We usually use 2x6 form boards and re-use in subfloor. I can use py, and
snap ties although the footing is a rough mess......not even at all. It was
roughly poured to handle 8" blocks. I suppose a person could attach a 2x4
to the rough footing and then go from there....
Either way it is a tough situation.
