You would need to tunnel under to install under the garage. You can jack hammer a hole in a post tension between cables without any trouble, for the door

Need to find someone to do the underground, in the garage option.

Texas storm shelter guy in Sherman did mine. I got an 8 person above ground Tornado safe shelter in my garage. He bolted it to my slab. Its supposed to with stand an f5. Makes my house hold so much more comfortable for the kids around storm season. 4800 out the door. I don't have post tension slab though.

just check the National Storm Shelter Assn. (NSSA) Website for reputable dealers in your area. Lots of full below ground shelters available. The most popular style looks like a giant concrete cube with one edge shaved off. It is installed 2/3 in the ground and one third above ground. Sink it in the ground just off your back porch. Live with peace of mind.

I know a couple of folk (family) who used those black plastic water tanks set in the ground attached to horizontal anchor points with air vents and a hatch exposed above ground. They both keep a battery sawz-all and drill in there for cutting their way out if need be. Its about 10 feet behind the back door.
It was fairly low cost for even the backhoe and concrete work.
I personally believe it would withstand.

Any of those undergrounds have a drainage system or sump pump?
Sure would hate to be in one that filled up with water and you not be able to get out. Ventilation?
Our old timey storm cellar out on the farm had a curb under the overlapping steel door to keep water and snakes from getting in. The cellar itself was lined top, bottom and sides with big Bois d Arc logs and had shelves for canned food and about 2 feet of dirt piled over the top. It was always nice and cool down there. Had a small stove pipe out the top for ventilation. We could get the whole fam damily in there and a few neighbors too. Probably 15 or so people.
