Tools To Find A Great Pool Contractor: New Pool Fairfax Va. Alpine Pools

Hi Everyone. New to the forums.

We have a proposal for a new pool from Alpine Pools. We're going thru a landscape design company and they say they've done a lot of pools with them. Anyone have any experience with this builder here in northern Virginia?

Here are parts of the proposal and equipment lists. We know nothing about any of this. Please let us know if this is a good build or any recommendations for changes!
