Shallowing pool and adding new tanning ledge and diving rock

We’re doing a major overhaul of our 1980s pool—converting spa to 8x7 tanning ledge, and extending the shallow portion, replacing the diving board with an overhanging jumping rock, and removing the ladder and installing a bench/ledge so kids can climb out. The finish will be a dark blue/grey pebble coat. And the deck will be porcelain pavers (EverBlue) that look like bluestone.

The plan is to shoot concrete later this week, but I wanted to make sure everything is being done the right way. Any suggestions based on the photos? We want to significantly increase the area people can stand but the steel in the mid area only extends about 3’. Should we go further? Plaster is still intact—are they supposed to remove or do anything else before gunite. We are new pool owners and want this pool reno to last 20 years.
 
I personally haven’t seen Shotcrete applied directly to plaster, only to existing Shotcrete that has been properly prepared.
The new rebar may be required to be epoxied to the existing Shotcrete, even if it’s not it would be in best practice to do so.
It’s not recommended to feather down to 0” , 1” minimum is typical, thicker is better.
I would suggest removing all the loose byproduct that is in the picture from the spa wall removal.
Insure that what ever base is being applied to that it is properly hydrated before Shotcrete application, then standard hydration requirements should be followed after application.
Now is the time to think about a umbrella sleeve location if you desire one.
