Not sure how to respond since I am not an expert by far, however, I respect your comments.
I believe that the steel tex and rebar become "encased" in the gunite as you said, on both sides.. As for how they are tied, yes I believe they are tied at 12" (1 ft). It is getting inspected either today or tomorrow. It must meet code or won't pass. From the reputation of the co, I know they do code work. Whether they EXCEED code is another question. Perhaps what you are explaining is work that exceeds code. I'm not saying we skimped, but we did opt for their very basic pool. I know if you "upgrade", there is perhaps heavier rebar, etc. but as for code, I am confident they are building to code.
Honestly, I could not see your picture closely enough to see anything different, except perhaps around the perimeter. Your pool is quite large - wow.
This pool is 14x28, a large bathtub. Im sure this doesn't have any bearing, but I will mention this to our guy when I see him.
Thanks for your input.
