Here, in Central Mn the town that I live in a commercial building must have a sprinkler system installed if you are over 5000 square ft.   You are well over the sq. ft., your building might have heavier specs on the engineering for the poles and footings.  Most commercial buildings will have frost footings around the stoops and all exterior doors so they operate in all weather conditions without doors heaving up from frost.  If the building is going to be heated you likely have a insulated styrofoam frost barrier around the perimeter too.

Trust me I have witnessed first hand the extra costs of pricing a commercial building.
