Title: RE: Footing Steps

I have done it both ways: stepped the footing and had it connect into another wall foundation.  If I do the latter I always dowel into the other footing.  I will generally only do the later if it is not carrying much load.  If it is a major load carrying foundation, then I will step it.

Hope this helps,

Scott

I am curious as to what others' philosphy is regarding stepping of
foundations down to a lower level. I typically try to step them,
however, there may be instances where the steps would be too many or too
steep to properly be accomodated. I have seen others' drawings where
they simply run the upper level footing into the side of the foundation
wall of the lower footing. This seems OK if the soil is compacted well
beneath the upper footing or the wall is reinforced to span across this
weak zone of backfill. I always require that the concrete walls be
doweled together.

What do others do in this circumstance?
