That is the way I had my wood shop done. No cracks after 10 years.

It's commonly done, especially with steel prefabs.
It is called a floating slab, I think.

I’ve done a couple small jobs where we had builder’s tubes in place for load bearing supports, that were poured at the same time as the slab. It does require some prepwork, works well though when done

I guess I never thought of a thickened edge as a footing.
I'm envisioning a footing higher then the slab.

Its very common down here,we call it a monolithic slab.

But i would have very big,wide and thick places under the building supports.
We have a very big need for that,we call it uplift.
Hurricanes are no joke.

In Fl a friend was building a steel building and code was for like a 6x6x6 foot footer under each post,with the bottom compacted to a certain spec.
They had an inspector on site testing each hole and the bottom of the footers.
I had never seen that before.

I watched a log home eing build and they had a big post in the middle of the great room,it was required to have a 4x4x4foot block of cement poured around the post,for uplift.

I did a 20x24’ addition, single level. The centre beam needed a post, and that called for a 30”x30” pad, 12” thick. I doubt there would be more than 500-1000 pounds of weight on that post under normal loading.

Here if it has a thickened outer edge for a ‘footing’, it’s generally referred to as an ‘engineered’ slab.
