For section 680.26(B)(2).. Perimeter Surfaces; using 'alternate means' instead of 'structural reinforcing steel'... how should the conductors be installed on the perimeter of the pool? do you loop the conductors around the pool, or do you make a wire mesh with the conductors? Is either way allowed? if you make a wire mesh, what should the dimensions be?
 
The single #8 around the perimeter is the alternate method. You would encircle the pool with the #8, following the contour, and keeping 18" to 24" from the inside walls of the pool and 4" to 6" deep. You would then run a #8 jumper to any pool equipment, such as the pump motor, salt generator, etc. Also, any metal surrounding the pool, or on the pool and any that is in contact with the water such as ladders and handrails. It isn't required to run back to the panel serving the pool, or the main panel. You also need to bond the water and that bond would connect to the #8 around the pool.
You can find all this in 680.26.

Thank you! So a wire mesh would be overkill.

When the perimeter bonding was first in effect, we had to lay down down a 2' wide copper mesh behind the pool wall where the patio would go, connected to the 4 tails. This was for concrete pools. Vinyl pools required a 3' mesh.

It was changed to a single #8 wire set 18"-24" that connected to the 4 tails. We run a separate unbroken wire from at least 2 points on the rebar back to the pool equipment.

I don't even know if the copper wire mesh is still available. Is it overkill? I don't know.
I have heard some towns still wanted the copper wire mesh. Very expensive and a PIA to lay out especially on a free form shaped pool.

Find out what the inspector wants.
 
In Massachusetts the copper grid (mesh) is required for inground pools...for the perimeter surface with pavers, etc. If a concrete deck is poured with reinforcing steel, then no mesh is required.

Dimensions for a copper grid is 12" x 12" intersecting squares...so as you can imagine that would be alot of burndies and labor. Better off buying the pre-made grid at the supply house. Cost up to $1000 for 100' roll 3-feet wide.

We did a commercial pool about 12 years ago. We ran the copper wire around the perimeter. My mason set steel mesh for the concrete and we bonded to that. Inspector said the perimeter copper wire was not necessary and that the steel mesh would suffice. I however felt more comfortable with copper wire also in place.

12x12 mesh copper last time I checked years ago was about half what you said!! And if you needed more than 100', oh well. Customer had to for a second roll.
