The 3K option is not viable because of the water. I know the space has to be protected if they don't use FR lumber. I was looking for hints in case anyone has done this in the past and srtumbled upon a design that has worked well. The clear space from the concrete floor to the bottom of joists is about 1'-9". I assume CC sprinklers will be required
