Re: Building in AK
The absolute best and certainly most costly elevated yurt deck is gonna feature poured reinforced concrete piers set below frost line depth, with treated 4x4 wood posts, and supporting an engineered frame. A perfect example of this is under every deck in every home I have worked on in my 47 year carpentry career. The holes are frequent bored with a two man auger. I have done that a few times, and also with a one man auger as well. And spud bar-years ago.
Note: In a code enforced jurisdiction like the one I live in, that is what I'll deem 'standard engineering'. All bldg. depts want a stamped certified engineer plan for the deck, or you won't get a permit. They merely inspect what is on the plan. There is no pour unless they inspect/approve the forms.
They could >totally care less< what kind of financial hardship that places you in, and have zero interest in what kind of hassle it might be. It's stamped engineers plan or no permit. Period.
If you are not in a code enforced circumstance, or have a financial reason to build lighter, precast piers from Depot or Lowes should work. Add 4x4 posts atop those and frame the deck. If the deck is four risers or >30" in height, xbrace the snot out of the frame.
My deck platform sits on 12" concrete pads laying on top of the ground-not IN the ground- so I avoided a 'permanent structure-permit needed- so kiss my gov't @$$ restriction. I have 49-12" diameter x 3" to 4" inch thick pads supporting a treated 2x4 frame on 19.2" centers. No 2x4 spans more than 4' anywhere. Deck is one rise off the ground. Built in 2013, and bombproof in every way. No soil shift around here it is silty sand. This is for a 16' diameter platform, and it couldn't be any more solid.
Other decks I am not familiar with. Must be alot online with some research. If you want to see my deck, in google images search for: Bob Rowlands home made yurt. My yurt is the rustic one with green door and rafters either side. There are a couple deck details in the photos.
I don't know squat about screw piers so no comment.
Good luck.
