Looking good! A few thoughts... I went through a similar process when I built a 28x36 shop two years ago. Two things I did that have really paid off: 1. after initial grading (dirt), I had a guy come in with his bobcat and front attached vibratory roller to compact everything. 2. I then covered pad with 6" of #57 washed stone, plastic barrier, and then pored 5" of 5000 psi concrete with fiber. It has held up very well with no settling or cracking. I guess my main message is compact well, and go with more than 4" of concrete rated at least at 5000 psi. Be sure to add fiber to the conrete as well as rebar or wire as needed.
