Pool builder put fiberglass shell in 1" too low. We were planning for a concrete deck with formed concrete coping at pool edge with 1/4" per foot slope away from pool. With the existing pool height we'd have 0 slope. He's saying we have to drain the full/balanced pool, jack it up 1" and re-do everything.

I think we either need a 5" thick precast coping or some coping form work that forms a 5" bullnose. I don't think either is something that is readily available. Have booked flights for people coming into town this weekend for Easter. Ideas? Here is the form that we ordered:
