I do see a few things in your pictures that concern me aside from the level. I hope it is just that he has not finished this stage yet.
Oh, sheesh, please do tell! LOL! If you're talking about the missing buttress, it is off to the side and needs to be reattached. When they took down the pool, they left the pressure plates connected to the buttresses to avoid some labor. That one must not have stayed attached for some reason. I know he said some of the screws were stripped and rusted out and would have to be replaced so maybe that is the case. I noticed that buttress missing so I went out to look and it's sitting off to the side. What else did you notice? Thanks for all of the info everyone! I'll keep you posted as things develop.
