Do you have any details for advice regarding cooler floors? We did one building (about 160’ wide x 250’ long x 80’ tall) with insulation under the slab and are being asked to design another without insulation under the entire slab… there will be insulation in the roof walls and extend under the slab only 2’-0” at the perimeter of the building. The temp inside the building is to be 33 degrees Fahrenheit and we are concerned about fluctuations in temp causing the subgrade to freeze. Are we just being overly cautious? The slab is a 2’-0” thick mat foundation due to the loading and poor soil properties.
You will need to provide a 3-inch mudslab (which serves to both contain the underslab heating and provide a substrate for the underfloor insulation), a layer of underfloor insulation (6-inch minimum I would guess for 0 to 10 degrees) and an unreinforced wearslab for support of the pallets and racks.
I have some standard details I can send you if you would like.

Can anyone provide or point me in the right direction to find some standard practice and or details with regard to the various options for freezer slabs on grade?
Continuous service exposure of 0-10 degrees F.
Any help would be appreciated.
