'Nother concrete question

Maybe just pin some sonotubes to the ledge and run them up 8" above grade, then build a regular wooden floor frame. Use some of those steel standoffs so the rim joists aren't sitting right on top of the concrete piers. Dig out a few inches deep under the shed (before you build the floor platform!), put down a vapor barrier and cover it with gravel. This will keep the underside of the floor pretty dry. Run some chiken wire around the perimeter to keep the critters out. The entire diameter of the sonotubes should be located inside the sheathing.

This is one of those rustic camps, sits on a little fish pond in a little hollow, but for example this spring it rained all the time and it was strictly 4 wheel drive to get in or out. Sits about 3/4 mile back from the road. The challenge for the readymix truck is how narrow the field road is. It'd take me a month to cut enough trees to get the readymix truck in.

Good Luck,

Anything we build will either have to all float like a slab or be totally pinned to the ledge like with posts. We've got alot of moisture because everything's hung on the side of a hill and runoff is sometimes a problem. So anything we build needs to be overbuilt to withstand the area and periodic lack of maintenance. I don't want to be jacking on the shed every year...
