Bustanoj, this should be a very nice project when it's completed. The only things that caught my eye were:
- I see on the spec list there are 4 returns and two main drains. I could not tell however on the diagram where those return jets were positioned, although I just had my eyes dilated.

Not reading too well. So I was concerned about sufficient water flow to the skimmer(s).
- I also noticed the in-floor cleaning. I'm personally not a fan, but don't let that sway you just yet. I don't personally have one, so that should tell you something.

But I do see a fair amount of people who have had problems later. I'm sure the warranty will protect you for some time. Just consider whether it's worth the investment as opposed to a top of the line automated cleaner (i.e. Robot, Dolphin, etc). Speaking of which, did your builder include a pressure or suction side cleaner port? I didn't notice it. That might be a good option as well whether or not you keep the in-floor cleaning. Also, did they include an overfill relief port?
I guess my main concern for you (if this was my project) would be to speak to your builder about the necessity to have 2 main drains and only one skimmer and only 4 returns. I have 6 returns in my 16x40 pool. We typically find that strategically placed return jets are more critical for adequate water flow around the pool and to the skimmer(s) which help cut-down on dead spots and assists with overall cleaning. A drain can have its advantages at times as long as it's working properly which is another discussion altogether. You might also take into account the position of your house and the Vegas valley prevailing winds as they will either drive surface debris to your skimmer or away from it.
If you don't have a light around the location of the equipment pad, you might consider that as well; or at least an electrical stub-out for later (DIY).
Again, a very nice project with some good equipment and overall aesthetics. But if money becomes a factor and you have to pick & chose, I would think carefully about the amount of return jets, skimmers, suction/pressure cleaning line, as opposed to two MDs and in-floor cleaning. Hope my writing makes sense as I'm squinting with my messed-up eyes right now. ha. I'm sure others will reply as well Ask lots of questions and keep us posted.
