Hi all. New to the forum and think I’ll be using it a fair bit. I recently bought an acreage that my grandad used to own and on it are a few old cabins he hauled out of the mountains and set up on skids. The skids are just big ass logs that they notched out for 4x4’s that they just dragged into place. It’s been standing my whole life (42 years) and who knows how old it is but those logs are starting to rot out so I need to fix the issue. I’ve got it lifted on some temp cribbing and trying to figure out best solution. I was thinking some 24x24 pads with some blocks on top (just read concrete > cinder and not really sure what I have up here already) topped with some PT spacers and run two new 8x8 beams. Cabin is approx 10’ x 30’ and I was thinking 4 piers along each side. One problem is I can’t get the old logs out as they built the floor directly onto them, so the new beams would go on either side and be pretty much on the edge of the frame. Worried about possible sag.
Interested in opinions on best way to handle. I looked into a professional as i haven’t done this kind of construction before, but quoted out at prices where it would be the same as just building from scratch. Wanna save it due to the sentimentality.
Pics of one end of the cabin and then to see the notched out space for 4x4 joists.
Cheers

I would take a chain saw and remove the pieces between the joists first. Then knock out the remaining pieces with a sludge hammer.

Do just like you said. Put new skid next to the old one..shim each floor joists as needed. It looks like those old skids rotted because they wernt under the wall. Dont leave the new ones long like that.
Also a 8"x8" beam sounds strong and looks strong but you get strength by beam height not width. I havent done the calculations but 3 2x12 may be the same strength and a whole hell of alot easier to deal with under the cabin.

Thanks.. looked up some charts and while I’m no expert, thinking 3 laminated 2x10s might be sufficient. Good call on way easier to handle as well. And as I’m still close to the ground figured I’d just use PT for the whole beams rather than just a PT spacer.

I thought about that actually but super tough to get at safely with the saw. I might just cut off the ends so they aren’t protruding and inspect closer to see how bad the rot is. Worst of it is definitely on the exposed ends and at just one corner of the cabin that started to sink
