Rain last night! Water, the ultimate leveler, slab base looks ok.
The existing exterior wall at the far end will have the sheet metal removed, but there is insulation underneath so that needs to wait. But the new slab will come right to the bottom of the steel, so I need to remove the lower couple of inches to give the finishers room to work. You can see the top of the new form on the left, and can't see the concrete the slab will abut.
Here is the other end. New form on right, this last sheet was a little shorter. These sheets were reused several years ago when we closed in the north 20 ft of the west shed to make a planer room. You can see where the concrete came under the forms for that floor. The new slab will be just above the bottom of the old form.
This morning I marked out the elevation to cut the tin and sawed it off. Really nasty work in the wet and almost too close to the grade to cut. But, got it done!
You can see the old form line and new top of form almost line up. I would rather there was more overlap, but this will work.
Inside the shed the floor mismatch is worse. It's hard to get a picture of both elevations.
The existing floor is about three inches lower than the threshold on the white door. The new floor, on this side of the wall will be about the elevation of the bottom of the ragged concrete under the door.
The wildfire that burned my shop in '88 or so (I really don't remember), left me with a 24x60 floor. The shop I had built was 24x60 with two 20 ft sheds, making it 64x60. It was timber framed with 1x12 oak siding, built in '85/'86. After the fire I was working too much to rebuild, so I cleaned up and hired the current pole barn built on the existing slab. I had it built 30x60 with standard 15 ft pole barn sheds so the new poles would not match the old pole foundations. That left me a 3 ft gap on each side of the slab to the wall (old 24, new 30).
I poured the gap without rebar knowing it was at the edge of the slab and would not have any real load on it. The ragged edges you see are where the forms and soil under the edge of the new pole barn were filled in from the inside. The 3 ft pour has held up well.
Here's a view of the concrete strip inside that door, the new concrete (1990) is whiter than the old slab that burned.

I'll fix it right later, after I wipe it off
