Does anyone have any diagrams, photos or descriptions on how to run the rebar for the turndown on a monolitic slab? My steel building plans call for wire mesh in the upper 1/3 of my 4 inch slab, and 2 continuous rebar running the lenght of the bottom of the footer with a min of 1' overlap, but for the rebar in the turn down the plans states "rebar plans by others". I had planned on bending rebar to reinforce the turndown and had planned on overlapping the turned rebar by a foot with the wire mesh, but what spacing do I use between the turned rebar and how far down the 18" turndown does the rebar need to go. I remember seeing a photo or diagram of how to do this, but I cannot seem to find the photo or diagram. Any assistance would be appreciated. The footer is 16" wide and 18" turndown, which includes the 4" top of slab.
