Pool construction involves some pretty specific trades: Plumbers (who know pools), Electricians (who know pools), excavation (probably needs to know pools), concrete forms / rebar (need to know pools), shotcrete / gunnite application (needs to know pools), plastering (needs to know pools). If you know subs with these skills and can get on thier schedules, you probably wouldn't be asking the question here.

Hire a reputable pool contractor - it is expensive but he(she)'ll know how to get it done.
