Pole buildings are put up first then they use a pressure treated 2x8 along the bottom as a form to pour the concrete floor once the prep has been completed. You can see in the last photo daylight under the edge of the building. They do this so you can bring in the 4 or so inches of crushed gravel, compact it then lay down the vapor barrier, re-bar or fiber mesh then pour the pad.
