Poured concrete last weekend.
I did the prep myself, which included the removal of an old, home-made car port, relocating and releveling a 12 x 24 shed, removing 4 trees, and adding about 10 yards of dirt to get everything level. I have pics of most of that work, but they aren't with me at the moment. To this point, the only thing I haven't done is actually pour the concrete.
Then, on Sunday, I redid the wiring to the back side of the shed and added an external outlet box so that power would be available when I start framing.
I'm hoping to be framing this weekend or next.
