The rebar, I was told wasn't even needed for this application. It was free and was installed by the prior construction worker. The company that came second to finish the pit took over the plans and got it done to what the machine pit dimensions required. Was told to leave the extra rebar in since it didn't hurt anything. I'm sure it's 6 here half a dozen to the other and everyone would do something different but it's in, it's anchored, and it's not coming out.
