Looks good to me and I have built hundreds of them. That is a pretty fair representation of what you have to do to install an in ground pool except you didn't show any pics of a shovel. Befote my son took over it was just the 2 of us and we dug the pools with a 863 Bobcat. We would dig the first day, shape , set walls and pour footings the second. Trowel the botton and install liner and plumbing and start filling the third. We would generally take the forth day and go install a couple of above ground pools while the pool was filling from the owners water hoses. It would cost the homeowner 30-40 bucks for county water, while having it trucked in was more like 800.00. We would come back on the fifth day and backfill. Now he does them every other day by having the water trucked in. It cost the homeowner more but he feels that he can make more money per pool by doing it that way. I'm from the old school and tried to save the homeowner every dollar I could, but he makes more money than I ever did and works less, so I guess I'm the one who had it wrong. Later, Nat
