What is considered "approved" tolerance vertically on walls after a framework erection? The carpenters say it is not possible to get it better or exact; it can never be achieved with a wooden house. But as a technician, I want to know what is considered within the acceptable range. I feel it is outside what is acceptable today, and there are no tolerances drawn on the plans, so in my view, the plumb line applies.
I will tell you what the slope is after I get some responses to the question. Please state in degrees or mm per meter of height. Note that it is vertical straightness, i.e., leaning inward/outward.
Grateful for input :x

In the first post in the thread below, you'll find the tolerances for walls from Hus AMA

Now I'm a little worried!
I took out my 1200 mm Clas Ohlson level and checked the walls, both exterior and interior, in my 4-year-old house built on-site.
And they all look straight, the bubble is well within the lines on the vial.
So it's somewhere within 1.5 mm/m as I understand it.
Why can't they build straight? Don't they have levels and just rely on eyesight?
But maybe it's different when setting up a prefabricated catalog house.
Then perhaps the assemblers are bound by the precision of the wall elements.
Someone knowledgeable should tell what is stipulated in Bygg-AMA or wherever this is regulated.
Oops!
Mr_bygg had already pulled out relevant info.

During the framework construction, there were major issues aligning it according to the specified measurements. There were measurement errors on the gable blocks from the factory, while the slab executed by us was control measured to +-2 mm, well within the tolerance set by the house supplier.
The carpenters provided by the framework supplier were supposed to stay until it was weather-tight and they were responsible for the framework assembly along with 2 experienced carpenters hired by us from a local construction company.
Now, 2 weeks after the framework construction, we discover one problem after another; most can be solved, but slanting walls exceeding 1.5 cm over 2500 mm in some areas feel completely unacceptable.
I have a meeting with the supplier on Monday, so I want to be well-prepared. They aren't directly to blame for the problems since they use a factory in southern Sweden that also makes blocks/prefab for other manufacturers, but this feels like a Monday example, or they were in a rush for the Christmas holidays.
Problems besides this include missing electrical pre-wiring in the walls, not consistent but missing some outlets and exits, a pre-installed balcony door that is crooked, construction errors at one window, missing drawing documentation, and the framework being executed differently than agreed upon without informing us. We did not receive the K drawings or other construction drawings until 3 days before the framework started, despite needing them earlier. The list goes on.
It feels like we have a good dialogue with the supplier but I don't think they understand the extent of the problems. It's piling up and they must address this with the factory; in 3 months we will be without a home if we don't have a house to move into.
I will start by thoroughly documenting everything, even if I would rather spend the time on something more productive instead.
