92 today @ 53%
Not a bad idea, so you just cut them off when done? How to keep them from rusting?
Pouring steps down to the creek/swimming hole...nope, never done it before!

Concrete snap ties are made to keep forms from spreading during the pour. Once the concrete cures, they can be broken off and leave a hole to be filled later hiding the tie.

Order low slump concrete (2 or less)and pour slow.
I would add both external 2x6 and internal form ties. The internal form ties should have large washer against the wood forms to prevent the ties from pulling through the forms
concrete will be pushing around 150 pounds per cubic foot against forms

Yikes, internal form ties might be hard to find in time. I might have to resort to a 1/2" pvc pipe and all thread/washer.

We pour today. Finally got in touch with my neighbor who has been a concrete guy most of his life. He inspected the forms and made recommendations to beef them up, like those on this thread have already done. We were in the process of doing that when he arrived. He thought a 4" Slump mix would be about right for this pour. Since I know that means thicker than normal, I didn't know what it really meant. His description:
Picture filling a traffic cone with cement, then turn it over on the ground & remove the cone. A 4" slump means that the wet crete will bulge out of its cone shape by 4". A 0 slump would have the cone shape not bulge at all, while a 10 slump would result in a large puddle of mud.
He also cautioned the use of a vibrator for this type of pour, and thought that tapping on the forms lightly would be a safer bet in preventing blow outs. Since I don't care about minor void imperfections, I nixed the vibrator for today.
Hard to tell in the pic's but the staircase next to the pigs has a lot more volume, so it appears taller due to the terrain. He thought that filling to less than 50% of that form first, then moving to the other staircase might be wise. I think it's a good call, so wish us luck.

You have chosen a very challenging project, but with a little luck, and a good accomplice it may pull off very well for you. It sounds like you have listened to to a lot of peoples suggestions and come up with good solutions to your issues.
Good luck today!

The pour went...ok. The only problem was almost a fatal one....5 old bastages don't move fast enough and the 4" Slump started setting on us in the middle of pouring the second staircase. We also certainly could have used a vibrator, and I kick myself for not going and picking it up to at least have on hand.
We started on the higher volume staircase with the intent of pouring it half full, letting it set a bit, while pouring the lower volume one. It was immediately apparent that the mud was so dry that we knew the forms could handle the full pour, so we went for it.
We left a man on the 1st one and moved to the 2nd. A few steps up, we had the driver pause while we leveled things off. 10-12 min went by, and when he tried to send us more crete down the chute, it was stuck in the hopper. We took a shovel party to it and got it broken up, dumped that off to the side and continued filling. The driver said we had to hustle as he could feel the mud curing in the Mixer. So we went with no huddle and got the form full.
I was off by about a yard and a half, so we had left over to put across the top of the rip rap where the water current is strongest(in front of the short leg of the pig wall). As the mixer rotated, I could hear the load banging one time per revolution....but it came out and was spread ok.
It was then a mad dash to get the steps edged, which was a pain in the .....!*#(yes, champhering strips would have been way better)
All in all, I don't think we could have moved any faster. Pulling the forms off today, and loading pics now.
We started at noon 15 and quit at 2:30.

We put 50' of 1/2" in each form....could have used more since there was plenty of room.
