This was a very interesting subject. Please correct me if I am wrong, if the soil report said allowable soil bearing is 1,500 psf (assuming it is the maximum allowable value. unclear that if any special foundation preparations are needed) for footing founded between 0-10 feet deep and structural demand is indeed less than 1,500 psf, then the "mud slab" may not be such a bad approach. The footings will gain the bearing support as recommended by the soil report and the mud slab will also serve as a working table over the "soft" soils.
However, if the pressure from structure needs more than 1,500 psf, the footing needs to be sized up accordingly, but the mud slab in this case shall not be considered to provide structural value.
