I'm trying to keep the updates pool-centric but since the pool is integrated so tightly with the building I thought I'd still update with these...
The slab surrounding the pool is 2700sf. Here you can see more formwork going up over the last couple days so that steel can be laid on it. It is at this level what would normally be a bond beam on an inground pool is being integrated with the building shell -- a 24 x 16 beam. The beam actually runs all the way into the hillside into soil anchors that are then backfilled. Supposedly this is to minimise any downhill movement of the structure. the entire slab, beams and vertical pool walls will be poured monolithically.
As for the bonding, solid copper is not available here so stranded copper is sanctioned. Split bolts were used to attach to the rebar and at the corners, pigtails were left to tie onto the rebar in the slab. For 5/8" rebar and 2 copper pieces, the 350MCM size worked well.
No ladder, railing (wanted to keep it minimal looking) or metal niche is being used on the pool . So for the bonding of the water itself, I decided on placing a skimmer, although normally I find this redundant on an edge pool. I'd seen some youtube talk about the requirement being that the bond be made with water
always in contact and the pipe insert with the lug had me wondering. So I went for the
skimmer mounted bond kit instead . Maybe someone can suggest additional means of ensuring that water doesn't leak through the rubber o ring and the drilled hole....or am I just paranoid?
Can you tell we're big on safety down here?!
I've also started putting 'pen to paper' as to the trough details trying to finalise it all -- sight lines, volumes, etc... I've enjoyed reading may posts on TFP about sizing and so on. Some great resources on this site.
