I'm designing a combined footing w/ a new 1'-0" wide X 2'-0" deep cast in place footing over an existing footing. As min. (0.0018) requires (2) #5 @ 1'-0" for transverse bars. This seems like overkill and I believe the cost will get too high for doweling in (2) bars every foot. Is there anything you can do to get around As min. if you are doweling into an existing footing? Does ACI have any guidelines for creating combined footings (new w/ old)?
