A pole building relies upon the pole for several different things.
It needs to carry the roof and everything on the roof. A lot of weight. If you are on 12 foot spacing you must be in the south, up here in snow load they go with 6, 8, or 9 foot spacings.
It needs to take the side load a strong wind puts on the pole. So it depends on your winds, but who doesn't get a 70mph downburst every 50 years or so, so we all need good wind ratings.
It also needs to take the upward pressures of the wind in your area. I have seen several buildings that were pulled out of the ground in a tornado or microburst, as the wind got in a door and lifted it up like a balloon. The machinery all sat there, with the building crumpled 100s of feet away.
So for such a wide spacing, 12 feet, the wind rating becomes interesting. You won't have many poles to take that side pressure.
Now you want to put the pole on a pier. That puts a joint there on the bottom. That really really weakens your pole. So to keep your wind rating, you need a really strong connection between the pole and the pier. This will be the critical thing. It needs to take the sideways and upward ratings your building will get. And the taller you make the building, the more stress this joint will have.
A stick built building with a full foundation has many attachments, every 16-24 inches, to the foundation so it is easier to make that joint nice and strong. Your pole building, especially with a 12 foot span, is going to really stress that joint. Your old building with the poles in the ground, has a flex and grain through that joint area. Your new building with the pier is going to want to bend and stress right at the joint.
Just what you need to focus on, the weak point of your design.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
