Construction/Engineering question?

I'm planning on building a shotcrete pool almost entirely above ground. It's a basic rectangle 16' x 36' with a 3' shallow end and 6' deep end. The shallow end would have a tanning ledge with some stairs on the side. Since I want the top of the pool to be about 5' above grade, the deep end will need to be dug out about a 1' but the shallow end would need MORE dirt. That shallow end has me scratching my head on how exactly to form it up for the shotcrete. I'd love to upload a sketch but for some reason I can't.
