Well, we've officially started our first shotcrete pool. We are mainly a vinyl liner company, but a hot tub customer of ours owns a concrete company and decided to build himself a shotcrete pool. Noone within a few hundred miles builds shotcrete or gunite pools, so we're on our own.
The pool is 20' X 40' freeform with a bench and steps, 2 skimmers on 2" lines, 4 looped returns on 2" lines and 2 main drains sharing a 2" line. The pump is a Jandy Stealth 1 HP, Jandy CL580 Cartridge Filter, Jandy AE3000T Heat Pump, Jandy AquaPure SWG w/ PDA, 600 sq. ft. flagstone decking, diving rock, and built in bbq.
We've got the excavation, steel (#5 rebar installed on 8" centers, with a 20" deep beam with 6 #5 bars all around the pool) and initial plumbing done. They are shooting the shell tomorrow. Being a vinyl installer there are a couple things that I do not know, and I am hoping someone here can help me. When laying the flagstone decking, is it mortared onto the top of the pool. The flagstone is 2" thick and will be dry-set on tamped crushed gravel. Also, should there be any kind of expansion joint between the 6" tiles and the flagstone coping.

Thanks for the help.
