Place concrete tubing forms in the holes and level the footings about 1 inch above ground level. And that usually means lots of deck footings.

There is no frost line since this is a freestanding deck. This type of footer requires a good deal of work as you have to dig below the frost line which can be over 70 deep in some parts of the country. Up from the bottom of the footing.
