Listen to Ascew! She knows what she's doing and is a pro. If you're shy, get the conversation started with taking them drinks or cookies, etc. A man's heart is through...... The crews down here look forward to treats and really appreciate it. Our gunite crew came at 6 in the morning so I ran out and bought jalapeno kolaches and donuts. Man, you would have thought I had baked them myself. They thanked me over and over. I guess that time of the morning they don't take time to have breakfast. But it's also a great conversation starter.
I learned AFTER my dig what to look for. People have mentioned to measure the lengths, widths, and depths to check against your plan specs. Also check to make sure they haven't forgotten any features you want - sunshelf (check depth and size), rock wall, raised wall/beam, benches, spa (for sure check the dimensions here), etc. In my case, I wanted a walking ledge in the deep end, and I totally forgot. And check the slope from shallow to deep if this applies to your pool. I had no idea to think about that.....
And then enjoy the excitement that your build has truly begun!!!! Wooooo Hoooooo! Were are those pictures??????
