You can work the estimates, but every PT slab I have done has been over dug. Another poster hit it on the head, but reading further it needs to be said again. What works on paper, generally 12" wide footings for PT, rarely happens in real life. The footing will be 14"-16". Surface cracking in res. construction is part of life. The cost of keeping cracks to a minimum is too high. That said I would still do PT if the clay was very fat and expansive.

If you want the slab dug to the proper size then you have to be there bitching and measuring.
Also, good luck getting the concrete to achieve the correct slump. Most residential crews will not work with a low slump mix.
