I've got an inflateable aboveground pool we set up for my kids in the summer. Does NEC *really* require an equipotential grid be laid down before setting it up, and a ground electrode draped over the side? I mean, it seems absurd, but it sure looks like it; they even go out of their way to say this chapter applies to storeable pools as well as permanant.
To answer your question; pretty sure the pool guy will install the ladder, and possibly the bond as it SHOULD come designed for code-compliant bonding. If he doesn't supply the bond, you would have to. The customer will pay for it all.
