Only alternative 2 will work and you will need deep piers and void formers under the slab anything else will fail.

slab photos for your comments please

No the engineer should engage a concrete testing firm to core and test the concrete.The engineer can also perform a schmidt hammer test.

Looks like the concrete hasn't been vibrated during the pour.I would get it tested for strength.
