Residential Monolithic Footing Exposed Rebar

Recently ran into a foundation contractor who pours his footing + stem walls monolithically and uses horizontal rebar set directly ontop of his footing forms to hold up the stem wall forms. After the pour he has essentially #4 bar that will forever stick out of the stem wall and beyond footing face by 1"(after forms are removed). I have never seen anything like this however he claims he has done it this way for 30+ years and no inspector or engineer every questioned. Per builder the bar is not used as reinforcement and doesn't make contact with structural bars inside wall to avoid corrosion. Thoughts?

The metals don’t need to make physical contact. Contact via an electrolyte is sufficient. A moist concrete matrix provides for a good electrolyte.

Further, the surface around the protruding bars provides a locus for freeze-thaw damage and the penetration of chlorides and sulfates.

As always, the application matters. I wouldn’t blink if I saw this on a house. You’re lucky there’s steel in the foundation, at all. The “structural bars” are probably sitting on the dirt and corroding away, anyway.
