Demolition of Part of Load-Bearing Wall, how?
Hello
We want to tear down part of a load-bearing wall on the ground floor of the house to open up between the kitchen and living room. I'm wondering how to proceed? I assume that first you need to have a professional come and calculate how thick the load-bearing beam needs to be installed? What type of company do you contact for the calculations and the demolition?
Note, if this post should be in "hantverkare" please feel free to move it there.

Contact your lumberyard. They should be able to handle that. Otherwise, you might need to get help from a structural engineer. A bit over the top for a rather simple thing that there are computer programs for. Not everyone is expected to have it, but a good lumberyard should.
By the way, I can figure it out for you.
Need some measurements:
If you stand in the middle of the intended opening, how far is it to the wall in front of your stomach? =B1
How far is it to the wall behind your back? =B2
How wide did you intend to make the opening? =L
Assuming all these measurements are 3 meters each, it will be a glulam beam that is 56x270 with a support length of 66mm max deflection will be 8mm
The beam weighs 21 kg
17.5KN is the load you need to design a potential post for if you don't have a wall to lay the beam on.
Alternatively, a Kerto beam if you want a slightly smaller and lighter beam. Then it will be 45x260mm and weighs 16Kg
Incredibly ugly, though, must be built in.

A company will come now to calculate it and provide a quote...we will see what it comes to.
