suspended slab replacing wood deck
i would appreciate any comments or suggestions with regard to replacing an existing wood deck with a suspended slab.  the largest area is approximately 20' x 20'.  my particular concerns are:
1)supporting the form deck on wood girders; attachment
2)supporting the form deck / slab at the existing house band / foundation.
thank you,

it would be best if you contacted a local structural engineer to do the checking for you as a lot will depend upon the existing structure (ie its condition).
this forum could give various solutions but we would all be making a multitude of assumptions that should eb verified on site.
good luck,

codes usually don't allow concrete structures to be supported by wood.
