Helping with a log cabin build

I thought the entire Pacific rim was a seismic zone? Perhaps I should quit thinking.

No, you're right, but where SK's friend is building is considered pretty low risk for quakes. I mean...that region was formed by volcanoes once upon a time...and much of it was...modified by the ice sheets and subsequent great Missoula flood...but neither of those are considered a threat at the moment either.

A couple hundred thousand years and shit could get real.

All of this comes back around to years of engineers beating earthquake concerns into my head. Everything has to be tied down, locked together, stiffened, backed, and braced. The last addition/remodel I did had 23 hold downs in roughly 1100 square feet of space. The perimeter strap had roughly a 1000 ten penny shorts in it.

Yep…and because western WA has a high earthquake probability, that tends to bleed over into other parts of the state in building codes.

How long/tall is that post anyways? I was just taking a wild guess at 10'.

 

[skyking]

118.5" and that matches with the subfloor.
The rest of the log goes on top of that, an additional 27'.
I'll have to put him up on top of that with a man lift for the picture

Missed it by THAT much Chief!

(How the heck did I get within an inch and a half?)

Not keen on the idea of a 27 foot toothpick balanced on top of a 10 foot toothpick though.

That will be a fun day. Today I will make sure I have enough forklift to loft that thing, with rigging. I suspect not.
He'll have to get a crane for that day, and a boom lift. That is the safe way to do it.
We'll have the walls stacked to loft floor level, a load bearing wall like the basement one built, and mortises cut for a big glu lam from the back, log floor beam from one side, and also a locating brace from the other.
We will fix it in place with those mortices and braces.

We had to shim the rim due to variances in the concrete and mud sill. I ripped and planed all that, and cut and fed rim and joists. We got about half the joists in.

Trying to understand this pic. Terrific view!
In this view are 2 or 3 sides ICF?
Do the ICF walls get backfill placed against them or are there just no windows on those sides?
Is the rock under the foundation required for stabilization, plain fill or drainage?
Construction is different here in FL as you can imagine.

3 sides. The prow front wall is 2x8 framed. The icfs do get backfilled against, there are two windows 4x4s out towards the end of them. So the backfill will taper down and expose those two windows with the minimum of 6 in.
Rock is footing drain. Footings sit on undisturbed native soil.
