As others have mentioned call your local building inspector about those support posts or check your blueprints. They should show the elevation above grade the supports should be. As this addition is attached to the house I'm assuming you had blueprints drawn up by a architect?

If left as they are they will rot and that section of house will sag down the road.

I'm in the process of lifting my neibours center beam in her house 5" because someone thought would be a good idea to encase the bottom of 10 X 10's uprights in concrete. The bottom edge rotted. It took several years for this to happen but left without correcting the main beam (and first floor) will fall into the basement.

Oh.....and that pad is wrong.
