I was keying in on the loading part of your question, however, I think you are asking more of the framing part of it.

Okay, so it must be frame, either wood or metal framing.
The builder poured this slab and was planning to go full steam ahead with framing on it the next day. I doubt like hell that the compressive strength would have reached 2000 psi by then.
That part, for the framing, is where the ICC report Barry provided comes in - if they are using those Hilti fasteners.
Find out what fasteners are being used and then address through the manufacturer.
In the case of those Hilti fasteners, they require the concrete be cured to 2,000 psi minimum - so have the builder provide proof of that. Have him take a core sample and have it break tested, if it meets 2,000 psi, go for it, if not, wait until it does meet 2,000 psi at a break test.
Or.
Wait 7 days, then, regardless of what it has cured to (OMG ... but that what it says), then go for it.
