When we were working on my pool the PB told me about another customer that ran out of money right after they finished the Rebar. The pool sat at that stage for something like 9 months. Now after all the rain everything is ruined. All the trenches collapsed into the pool, all the rebar is rusted / bent and now the entire backyard is unstable. It is going to cost him 2x the amount to fix the damage.
Dig to Gunite on my pool was 11 days, it could have been done in 7 or less. We had 3 dead days in my schedule or it would have been like this:
Day1 Demo and Dig
Day4 Trenching and Plumbing
Day6 Inspections - Rebar, Plumbing, Etc
I live in SoCal and the weather was nice the whole time, so we never had to worry about rain.
If there is ANY chance of a big rainstorm during your construction get that gunite up.
There are a couple builds in progress right now that are having problems with the rain.
