Hi All,
So the big day is finally here!! Dig day is tmrw. So I've been doing a lot of reading here and other sites.
Quick question wjich is more important getting thicker rebar vs. 3/8" OR getting rebar 6" inch on centers vs. 12" inch thanks!

Rebar and Gunite
Concrete swimming pools are structures and, therefore, by code, require structural engineering. The exact rebar specifications should be designed by a structural engineer for a project.
Without getting into specifics, there is usually a range of specifications for things like rebar size, spacing of the rebar, concrete thickness, concrete strength, etc. At the lower end, the idea is to save money on construction. It is usually worthwhile to go above the minimum to help minimize long term problems.
It is best to inquire about the range of specifications, the cost differences, and the strength differences so that you can make an informed decision.
If you want to know what the specifications of the plans are, ask for a copy of the drawings and discuss them with the PB or the engineer. However if you disagree with the drawing, then you should probably be ready to scientifically / mathematically state your case about why you disagree and which building standard or municipal building code section your objection is covered under.
Try to refrain from requesting that x amount of rebar of your choosing be spaced at y distance. You will only alienate both the PB and Engineer with frivolous requests.
If the soil is an issue, you should get a geotechnical engineer to evaluate and advise. You may need piers if the soil is not considered stable.

It's always best to have an engineer design a plan for your specific project. Using "standard" designs only works for nominally standard projects.
