The poles sit over the poured pier supporting post. Instead pouring 6 inches of concrete they pour the pier just where the weight of the post will sit

In order to give sound advice there are a few factors to be considered to name a few , type of soil, weather in the area, elevation of the building with regards to surrounding area . Also the type of building open pole barn or framed and sheeted in.

Here in western Oregon where we get a lot of rain, pole barns are the norm. I have personally been involved with building at least 10 over the last 40 years. To date none have had any rotting posts that I know of. Most of the time, we have drilled 24" diameter holes and once the 6X6 PT posts are set, we fill with concrete. I think it's a solid way to build farm structures.
