Radiant Heat Part 2

I finished the radiant heat tubing install this evening. I am thinking about how I should install the basement walls etc. Thinking about shooting nails into the slab doesn't make for a good night's sleep. For now, I just need to watch how the framers install the stairs down to the basement. Maybe 2 inch nails and kick-ass glue will suffice. Any thoughts?

RD Davey scheduled the pour for tomorrow morning. Backfill should be done by Friday and framing is scheduled to start Monday, 10/2/06. Winter is comming . . . .
