Thank you for your reply. I am in Casper (my home town is Gillette) Both of the replies have been very helpful. The other item I am wondering about is: do I need to put cold joint material in a slab this thick and if so what The joints will be doweled together (two mats of rebar top and bottom).

Cold joints between pours should be dowelled together. Construction Joints are likely spaced 20 to 30 times the slab thickness. However, only having like 3 joints one way and two the other isn't all that great. In a 16 inch slab, I have joints between 20 and 32 feet O.C. That being said, with your slab, maybe put the joints at 25' O.C. along the 75' length and 21.5' O.C. along the 86' length. Is this what you're looking for???
