I fully expect them to remove the grass, level the area, place a compacted gravel base and pour in two sections using rebar or reinforcing wire of some sort. It’s got a slight, maybe 5-10 degree slope towards the property line, so they’ll need to take that into consideration when they order the mix, too.
I had a buddy at work get a Craigslist slab a couple of weeks ago in his back yard to park his boat on. His kids sent him a picture of the guy pouring the slab, and it was directly over the grass. Needless to say he was freaking out, but - too late! You get what you pay for….
