Not sure what you mean?? If your talking about the post yes. It is one piece of 4x6 from under the gound up to the truss carrier(header). I used sinkers to attach the header to the post.

Jim,
The wood was NOT PT, it's all natural rough sawn pine. Posts are true 6x6. I've been here 3 years (previous owner built the pole barn) and I can see the posts deteriorate before my eyes. My soil is a typical VT mix of clay, glacial till and good ol' farm dirt - all of which is great for holding water and drying veeery slowly.
When I repair it I will use the 'bigfoot' & sono tubes below frost line. I'll also encapsulate the bottom end of the posts with a self stick/seal rubber membrane that roofers use, and, tie it to the concrete pier with Simpson metal ties. I did 12" sono tubes x 4ft deep for a deck this summer, each tube held (5) 80lb bags of concrete & I could do 4 tubes in a day (dig thru pour, of course my BH doing all the digging & an electric mixer that held 1.5 bags of mix).
I hope to fully enclose the pole barn some day - the barn is 40ft wide x 80ft long - just think, 14 bays, 10ft high x 12 ft wide x 20 ft deep - and since I'm on an open field I'm concerned about wind and it having a nice big area to catch - I want this thing anchored.

Yeah, that's what I meant. I asked because I've heard of guys going .6 on the bottom and building out the top in standard lumber. Apparently you found some .6 lumber in 4x6 format, which is sweet.

I agree....you want it anchored. With the loader on a BX I could easily lift a large sonotube deck and pull the posts and concrete right out of the ground.

Jim are you unable to get .60 in a 4x6 or 6x6. Here I can get either up to I think 16ft long? I know mortan builds there pole barns that way. They use post frame construction up to two feet out of the ground then use conventional framing. I believe there reason behind this method is it’s much easier to insulate the structure. I have a friend who had a mortan barn built. Very nice but it wasn’t cheap.

Can't get any marine lumber......All has to be special ordered and along with the special order is the "special" price /forums/images/graemlins/grin.gif

Eric,
Pretty much everything around these parts is considered "ground contact" PT which is .4 The more serious treated wood is .6 and that's hard to find. The marine grade stuff is a lot higher something like 2.0, made for salt water. That's the stuff to get for long term survival. They use it for building permanent docks and bulkheads.

Cedar and redwood stakes lasted an average of 4-5 years before they were destroyed while untreated southern pine sapwood lasted only two years. Wolmanized pressure-treated southern yellow pine, however, is still in good condition after 20+ years of exposure. Predicted service lives for the various species and CCA retentions of treatment are listed in the following table.

W.R. Cedar Sapwood Untreated 3.5 years
W.R. Cedar Light Heartwood Untreated 2.3 years

Yeah, the .6 is awesome stuff. I just can't find it locally. When I build my barn, I'll have to special order the .6 or go for the gold with the marine grade @ 2.0 + /forums/images/graemlins/grin.gif
