Stamped concrete patio after lot grade

I just moved into a new construction house. I am looking to get a stamped concrete patio put in this summer. Grading of the lot hasn't been completed but projected completion by end of may.

I am getting quotes from contractors this weekend, what questions should I be asking to make sure the correct measures are being taken to prevent cracking or prevent much ground settling under the patio to cause cracking or sinking.

Thanks!

Going to get better reply's if you add your location to your profile.
You want to make sure it's graded away from the home.
It needs to be a couple of inches above finished grade so the grass does not over grow the slab, and at least 2" below any door opening, more if you in a snow area.

Thanks Joe.

This is in illinois in the southwest suburbs of Chicago.

The patio will be in front of a small deck used to walk out from the kitchen about 6ft up.

What's a reasonable price for sqft of stamped concrete, one color and one design?

One key will be the condition of the soil where you will have the patio installed. If it is fill (meaning no hard, virgin soil), which is likely close to the house, it is likely to settle. You can ask how the contractor plans to deal with pouring a slab on recently back filled earth.

Only way to get a price that's going to do you any good is to get some local quotes.
Any local concrete company should be able to give you some referrals.

Okay, is it better to pour the patio before the rest of the grading is done and grade around it? I think the yard still needs another 6 inches or so of fill.

The final grading is best done after the concrete work is done, that way you don't have to worry about equipment messing up the finish grade. You would need to account for the change in elevation so the slab doesn't end up being lower than the yard. Ideally you'd form the perimeter of the slab thicker and then fill the rest in with gravel so it doesn't take as much concrete.
