Prep Pole building for concrete slab

I need some advise.I have a 30x32 pole building that I,d like to geta concrete floor put in.There crush run in the building now.But I think I,ll need more.The question is ;there is a 6-12 inch gap below the botom pressure treated 2x8 boards that wrap around the bottom of the building.I was getting ready to grade the crush run.But I was wondering if I should add boards to close the gap?Or add more crush run to overspill to the outside until it closed the gap?Also the later may not be a bad ideal because the is alot of chunk rock and dirt from the holes we drilled for the poles.

If you don't mind seeing rock around the edges of your pole building, you could just let it spill under. Make sure you've got plenty on the outside so it doesn't wash away over time and undermine the slab. If it were mine though, I'd add the extra 2x8 and pour a thickened edge. It just looks cleaner. You'd use a considerable amount of extra concrete doing it though.
