Level floor structure with shims?

[JohnMW]

The choice of wedges here indicates that the thought process hasn't been entirely correct. These wood chip wedges will dissolve due to changing humidity within a few years. If it had been packing shims intended for both long-term load, you could suppose there was a thought behind this, but the execution combined with material choice is collectively a wrong approach.

The wall will obviously settle if it hangs in the air over long distances, which is completely incorrect. This will naturally increase with the weight of the construction. The notches in the floor joists must also be checked with a construction engineer. If the height only permits such a sunken placement, notching might be unavoidable, but then the attachment should be adapted accordingly with, for example, a joist hanger against the foundation wall or equivalent.

Getting a construction engineer on site is a strong recommendation!

Very grateful for all the answers! What is the purpose of the bottom sill if the edge beam and floor joists have support on the wall with sill plate in between? Regards, John

To distribute the weight over a broader area, and to raise the bearing joists from the masonry.

Who made the decision to construct the floor structure as it is now?

Constructor omits the sill?
This isn't even difficult!
The rest of the house and all the hundreds of thousands in costs will rest on loose ground, it's throwing money down the drain.
Start over and do it right.
Take down the walls, or perhaps start everything from scratch is the best, cheapest, and most serious suggestion so far.
Knock down some of the foundation and shape the inside or whatever is best in this case, and make a proper foundation to place the extension on.
Yes, it's tough to stand your ground now, but it will pay off in the long run.

Good luck.

Now I haven't seen the whole picture, but demolishing the whole thing might not be necessary: If it's just a frame, you could probably lift it with jacks and build up underneath...it doesn't even seem like there are roof trusses yet?

Now, I haven't seen the whole situation, but tearing down everything might not be necessary: If it's just a framework, you might be able to lift it with jacks and build up underneath... it doesn't even seem like there are any roof trusses yet?

Hi! The next step is the roof trusses, but I've halted it. The owner is coming out tomorrow to present a plan of action. Since it included adjusting the wall if needed, I find it hard to see any other solution...

Sounds reasonable.. please update as you make progress😉

Will do 👍

Unrelated to the issue but damn that's filthy. Lumber should be dry and clean throughout the construction and especially when it's being built in.

On my screen, the images are displayed upside down. The wedges seem to be pieces of spånskiva. Sawing notches in the floor joists that way must mean that they are significantly weakened. Screwing an extra support beam to the wall under the floor joists is probably the simplest solution.

Yes, but there's a sill, and sill paper is between the wedges and the stone. How it looks under the sill cannot be seen.

The sill is not under the entire standing stud, whether that's okay I don't know, someone needs to calculate that.

I take back what I wrote before. The images were upside down on my screen. Now that I see them correctly, I see how crazy it is…

Just need to redo it, I think...

 

[Nissens]

If I interpret the images correctly, it is directed horizontally, not vertically.

The wedges do not appear to be secured in any way.

If you secure the wedges (preferably drive them in from opposite directions as well), then I think it's okay.

I take this back because I saw the images upside down and misinterpreted them. It's fundamentally wrong and needs to be redone. It's doubtful that it's okay to notch the beams either...

I'm starting to feel like a parrot.....
Redo, do it right.
The more I look at the pictures and read, the more convinced I become.
Stop the work, good!
Tear it all down, just as well.
Redo, repair, adapt the foundation to the upcoming construction.
It is super important to do this as the next step.
Then I wonder what the contract looks like, maybe just follow it, and it will be fine, or it has to be rewritten entirely.

Is there any common thread here as to why it has gone so badly?

It seems like the height was a problem...

If you secure the wedges (preferably drive them in from each side as well) then I think it is ok.

The wedges seem to be made of particle board???NOT GOOD

No, totally crazy!

What is the span of the floor joists considering the weak dimension of the attachment?
