I have a carport that I am going to enclose. I will pour a concrete slab, but there are two load-bearing posts supporting a glued laminated beam. These posts are located where the slab will be, so I see 3 options but don't know which is best:
1. Moisture-proof the post and cast it in
2. Place edge elements around the post and pour around it, so no direct contact between the post and concrete
3. Set up props and support the glued laminated beam. Cut the posts and pour the slab, then build up the wall.

Spontaneously, without knowing what your thought is, option 3 is the best. However, depending a bit on how it looks and what your plan is, it might be possible to cast only internally. That means you don't really need to concern yourself with the load-bearing pillars at all. But it's difficult for us to know without any info.
I agree with @C.Lundin. Make the plank narrower. That's the easiest. If that's not possible, option 3 is the way to go.
Thanks for the response,C C.Lundin said:
This carport is attached to the house and shares the "same roof" as the house, so I want to convert it into living space without it looking like an extension really. If I were to cast the slab narrower, what would the walls stand on then, do you think? The pillars currently stand exactly where I want my outer wall to be.
There is no advantage in mixing the foundation of the columns (I assume footings) with the slab. If you want to do that, you need to cast an edge-reinforced slab. The existing columns form the foundation for the outer wall.
