Many years ago, large parts of a load-bearing wall in our new house were torn down. To compensate, there are two supports in the garage. Above is the bathroom, which is now going to be renovated, and before that, we want to arrange the garage. We have been advised to remove the drywall on the ceiling so that we can see that what we install will make direct contact. Two pillars along the wall and a laminated beam across the ceiling that is in contact with the load-bearing wall above. What should we choose and what dimension? Grateful for answers!
As mentioned, you need to bring in a structural engineer to calculate the dimensions required. It is also often a question of whether the foundation where the pillars will stand can support the load.
Since it is a garage, there are likely (not sure) requirements for fire protection. A garage is considered its own fire compartment. That means the glued laminated beam must be dimensioned to withstand burning for a while. Glulam is actually better than one might think in terms of fire resistance; it forms a layer of char on the surface that insulates so that the beam's core does not burn.
What you describe is also an action for which you must submit a construction notification. You must be able to present load-bearing calculations to get approval.
It is probably a smart move to fix this before you renovate the bathroom, as there is always a risk of some millimeter settlement when doing such support work. It would be unfortunate if the new tile floor cracked unnecessarily.
