There are risks you take when you become the "general contractor" when you do an owner/builder pool. Some of the risks are people getting hurt on your property, mistakes that every sub-contractor passes on to the next one and god forbid the pool popping out of the ground during construction. If you are willing to take these risks you can save yourself some money. Make sure you have the time to meet every sub-contractor on the job. If you have any questions PM me, I've built over 4000 pools.
