Cantilevered concrete coping build question

[puppycrack]

I am about to pull the trigger on an IG vinyl 18x36 pool w/ cantilevered concrete coping in Rochester, NY. I am planning on a broom finish concrete deck, with #57 stone or similar as backfill. The pool will be dug and backfilled in the fall, and finished in the spring, to give a good amount of time for everything to settle prior to the concrete going in. I spoke with the PB, and they said that with cantilevered concrete coping, the masons they use prefer to put it in before the liner, else it gets "tricky". When asked how they would achieve that with the split build phases, they said they would:

1) Dig, install pool walls
2) Do the concrete bottom
3) Backfill
4) Put in some sort of temporary liner (or something?), so they could partially fill the pool
5) Put up temp fencing (but no cover to the pool)

WAIT TIL SPRING

6) Pump water out of pool
7) Pour concrete deck, including cantilevered coping
8) Install liner and fill pool

Is this a standard industry build practice? Are there any red flags w/ this process? It doesn't *feel* right to me, but again, I am certainly no pool construction expert.

Thanks for any and all insights! And Happy 4th of July!

That's strange, but I'm no PB either. Everyone I met with and finally decided on told me the pool was free standing. This is metal Wall with vinyl liner. Just FYI.

Not tricky at all with the right mason. I will post some pictures tomorrow of the forms they used. Did an excellent job. After almost 3.5 years since the concrete was poured, I only see a small hairline (very very fine), and not even a crack in the coping. The deck is stable. I did although put down crushed stone prior to pouring. Will attach some pictures.

The liner should go in first and there was no mess at all. Only the powder from the stamped concrete.

I'd love to see your pictures!

The coping form was a Styrofoam type of material and the anchors are also shown in the picture. Do not remember exactly how they supported with the anchors, but the forms were removed the following day.

I put crushed stone for drainage and the part where the dirt is was done at last minute. Moved out a little bit. The mason came a few weeks before hand and placed the forms for the pattern so I can use the crushed rock. So far, so good as there are no cracks in the cement after 3.5 years.
