And I think that nails the biggest problem in this thread -- not enough  
information provided by the OP.

I haven't read all of the postings to this thread but in what I did read,  
I didn't see anything about specifically what it is about the slab that  
(in the OP's opinion ) justifies it being demolished and replaced at the  
contractor (or sub-contractor's ?) expense.

It's entirely possible that the shortcomings (the nature of which is an  
unknown at this point (to me anyway) are due to poor (or just plain bad)  
design/specifications.

In order to make any sort of reasonable assessment of the situation (short  
of a site visit) I think that one would need:

(1) cross section of the floor (ie including everything in the supporting  
substrate .... if wood framed, that would mean joist size/spacing/span,  
sub-floor material/thickness, separation membrane, concrete mix used,  
primary & secondary reinforcement details, some idea of concrete  
placing/finishing/curing process followed, control joint spacing

... blah,blah blah.

Without that info, we're just taking pot shots in the dark.
