Stop in for a cup of coffee

I put in a lot of rebar, drilled and pinned to footing. There is fiber they add to the concrete Now in place of rebar.i should have asked to have it added. Should have gone 6” or better. We get a lot of frost, and the “clay” is more like silt. It had a good gravel base too.
My foot plates on hoist are 12” square,they do spread the load pretty well. I dont think the hoist caused the cracks.concrete was in trucks 45 minutes,from what i understand thats a little too long for the mix they supplied.
