Started preparing the yard for the pool. ThevPB also just submitted our permit request so excavation may be coming soon. We are excited to move forward with this project.
Are you OCD or comfortable handing it all to PB?
1st permanent change that cant be fixed later is the dig size.
Walking the actual shape of the pool is different from seeing pictures and design plans.
They should spray paint and talk with you in advance. If you want to be more proactive you can buy a cheap 100 feet of twine and stake it out yourself.
I added about more feet (original was not wide enough for me and bumped to 16 feet wide) and tweaked the shape of my pool after staking it (free form...so maybe not as critical for your rectangle)
