I am planning on building a 40' x 48' Monitor Style Pole, 16' x 48' (10' high) aisle, with (4) 12' x 12' stalls on each side with a 16' x 48' loft above the aisle.
Does anyone know where I can find information on what size post and spacing I would need to support the loft/aisle area? I wanted to use 8" x 8" x 16' PT post burried 4' deep space every 12' on center. When I priced these post they run between $95 - $120 a piece. Then I looked at using 6"x6" posts. They are about $35 a piece. Could I use 6"x6" posts instead of 8"x8"?
Thanks,

pole barn
Well I might go this route. I am getting a qote to have a builder put up a 40 x 60 pole barn - then I will add a apartment. Cheap and fast method of building. I might be in Wyoming sooner than later
strength of posts
posts take two types of loads, compression and bending, the ratio of the compression strength is the ratio of the areas. Assuming rough cuts (6x6 is actually 6 inches square), the 6" posts only can take 56% of the load. the bending allowable goes as the dimention cubed. Thus the bending is only 42% These are significant knockdowns, and I would be leary of using them (especially if I did not do the engineering). They may be safe, but they also may not be.
You can get a 12" diameter log for ~$2/ft. these will be stronger than either post. You might consider that.

Where can you find 12" diameter logs for that price?
logs
look around. I have a logger providing my houselogs. You'll have to pay for shipping too. Then you'll have to peel. it might be worth it.

pt poles
I don't know about pole buildings or requirements, but I think you could put the poles on PT pads, similar to the way we put PT on cement piers. Oh, I forgot, you can just mill off the bark to be a single cant post.
