Make a provision to be able to have access with a well rig to be able to get above the well to pull it if ever need be. In addition make your roof above with an opening to get the cable from the well rig to the well head without having to tear a part of your roof off.

I wouldn't build around a well house. One day you will have to access that well and having a building around it will only make it more expensive to do so. Unless your shop is going to be 30' tall and include an overhead crane to pull the well pipe anyway.

Why don't you build the 40'x60' next to the well house? Building around it sounds like a horrible idea.

Lots of folks in our area do that because of the cold temperatures that can be experienced. We are -2 this am and have not been above 20 for a couple of days.
Many ranches here have their wells, pressure tanks, water softeners, etc built into a corner of their shops. When pouring the slabs they lower like a 10 x 10 or 12 x 12 part of the slab down about 3-4" and put a floor drain or a way for the water to get out in that part to prevent flooding of the rest of the shop in case of a catastrophic water leak.
This set up also allows the well and plumbing to easily be heated as to the rest of the shop and it's convenient for installing a bathroom as all the plumbing is right there as well.
When building the shops like this they design the roofs with a 4' x 4' framed opening with an easy provision for well trucks to service the well.
ETA: I will add that our house here has similar slab designs as both water heaters and our mud room/laundry room have 4" down-set in the slabs with large floor drains to prevent flooding of the rest of the house in case of catastrophic water events from the water heaters or washing machine.
