An expert excavator is important for the construction of a concrete swimming pool. Seemingly little things make a huge difference.
When setting the form, we use 2x6 boards so that the top of the bond beam is thick enough to be protected against damage from freezing temperatures.
I have heard people over the years express frustration that their pool builder did not build a pool as deep as they had planned. The most common reason is that the builder plans the pool depth from the top of their forms, which approximates the top of the tile. The waterline is normally 3" below the top of the tile, so 3" needs to be added to the excavation to ensure it finishes at the planned water depth. I realize that some will consider this a small difference, but to some people it matters.
Other things to consider when planning excavation depths include the amount of fall (or slope) from an existing patio, the thickness of the deck material, and the thickness of the swimming pool floor.
