Hi Kevin!
I dug out the last dirt last weekend and compact the sand with a machine. I was quite accurate making sure that it was leveled when I first went over it with the machine. Then I covered the whole area with 4" of gravels, I expect the gravel to shrink so I didn't put to much effort to get that 100% accurate. After winter will I level it with a laser so I'm sure to the right thickness of the cast.
I shall not be stubborn and questioning your experience when it comes to concrete and cracks but I have a few things I will do to not make them appear

It works at least in my mind. If you choose to put out all the rebar’s before placing the boards that decides where the controlling joints will be. If you do so it's good to place a hard tube on those rebar’s that goes under the controlling joints. That way you allow some movement there. Also, place the rebar that are highest on your carpet in the direction that arethe longest that way it take up more stretch in the cast.
A small thing I haven't seen in the average pool deck here on TFP despite 90% I’ve seen are poured concrete decks, is inspection panels in the deck where the joints are. All my plumping is made with a 2" PEM tube with 5mm gods which is freeze proof. And I have inspection panels everywhere where I have a joint, the same goes for the lamps junction boxes. I think that is a good idea that can save you head ache later on.
lids will be made out of dark hardwood that will be placed in the same level as the surrounding pool deck. I actually think that it can give the deck some character.
I did pour the foundation to the shower today! Great to have your own cement mixer

The surrounding pool deck will be 4" above the foundation and I fill that distance with white small stones that will surround the little hardwood "thing" that we will stand on while shower. the same hardwood that I will use as for all the inspection lids. I will place the foundation to the kitchen on the same level but I will not fill that gap with stones beacuse I will use it for draining the pool deck, hence the slope I will make to that direction.
I haven't yet cleaned out the pool and neither have I pout on the grout so I couldn’t stand take any pictures of it more than the shot of the stairs that I took from the outside. As you can see have I not finished the tileing around the skimmers.
After this long post ! Endless amount of pictures that not showing anything that you haven't already seen
Take care
Mats
