Best to use pros for design and installation. Cons usually don't have much opportunity to learn concrete during their prison stays.

God help you for asking an architect a structural engineering question.

Opinion: Both will work equally well. Rebar is easier to install and requires less attention. Better chance of getting a proper installation. Pay extra and get a good rebar slab.

Soil conditions also play a part in the decision of rebar vs post-tension. The post-tension slabs tend to hold up in North Texas a little better especially where clay is present due to shifting.

1. Where are you? (what soils)
2. How competent is the builder?

realize with the joke for concrete crap they use for most devellopers foundations, it isn't going to matter.

Oversize the slab and beam depth. Paying a little extra for concrete will save a lot of headache in the future.

Rebar is king. Too many variables for post tension. Crappy contractors who build homes/developments don't really give a crap. Don't use fly ash in the mix either. It's cheaper, but not as good as regular ol cement.

If this were 1992 rebar would be a cassette tape and post-tension the CD. Go with PT.
