I have questions about framing a basement. I want answers from someone who knows their stuff!?

The moisture barrier must be carried down to the floor and under the bottom plate. Seal the barrier join

with proper tape. I assume you will use drywall, so you can apply either 2X4's or 2 X 3's. Hopefully,his

moisture barrier is of the proper mil for your area code.

Here's the situation: I am framing a neighbors basement, starting with the perimeter wall. His perimeter wall is concrete, covered in a solid sheet of fiberglass insulation, (probably R-13) and a vapor barrier from the top, down to within about 6 inches from the floor. The height overall is about 8'. Also, the ceiling is already hung with drywall.

1. Should I use 2x4 lumber, or can I go with 2x3 lumber for added room around the perimeter?

2. Do I need a moisture barrier for the bottom plate? Should I use treated lumber, or a foam barrier?

And do I need to worry about a moisture barrier for the last few inches of wall and floor below the existing fiberglass and moisture barrier?

3. Should I shoot the bottom plate with pins, or should I drill and use Zamacs or Tapcons? Does it matter?

4. Is it better to fabricate panels, then shim the tops when I nail them into place, or should I just stick-build it?

I have lots of experience in commercial and metal framing, so I have the basic know-how of building, but I'm not experienced in wood or residential and I want to get it right. Your answers and added info are greatly appreciated!

Ask your parents if its okay to find a roommate off Craigslist or something.
