Our new pole barn is up and the wiring almost done. The flooring won't be poured until next spring. We're bulding a loft and are wondering if the supports could be put in before the floor is poured. Of course we would pour piers below the frost line and then set the supports, but is it ok to do this now and then pour the concrete around the supports? Or is it better to wait until the floor is poured and set the supports on top?
