Thank you so much for the quick response. Those measurements would much better, whew. I was thinking from the ground level plus a couple of inches for decking, then minus 6-9 inches for shotcrete.The top of the wood framing is the top of the bond beam (gunite shell) which is also the top of the waterline tile. So for waterline you need to go down 3" from that since your water will be 1/2 way down the tile. The floor will about 9" thick. So measure from 9" above the dirt to 3" below the top of the wood frame.
The deep end is definitely good, actually deeper than we thought Which is good because they told us they could only go 7 feet or it would cost more and the slope would be too great. The shallow end seemed a little shallow, but I think we were measuring it wrong.But regardless, CALL YOUR PB ASAP if you are not satisfied or have questions with the depth.
