What kind floor? Just curious.

We would saw cut and then chop. If it's metal Q-deck (vs. poured concrete) then torch the decking out after the concrete is removed.

Thanks!!! Could have rebar, right?

Exposed slab

You exclude all cutting, coring and patching and leave it to the GC.
You just mark out the hole and let them do it.

Rebar would not be the worst. Radiant heating or structural tension cables would both be really bad.

You could always have the floor x-rayed to be sure

If you are just bidding the job....do this.
Always exclude this type of work imo.
If you are the prime contractor responsible for the cutting....hire/get quote a concrete coring/sawing contractor.
Too much liability for you to do this

Ideally you fill the space with foam board before they pour, if not I agree with tkb and cdslotz.

If you are bidding this don't forget to include the curb that is required by 368.10(C)(2) if the busway penetrates more than one floor.
