You can export IFC from SketchUp. Not perfect (as many things don't come through well), but a wall will be a wall, if you classify it as such in SketchUp. For that, it needs to be a Component, though.
As an alternative, ARCHICAD can import SKP files. For some strange reason, some of my students modelled objects in SketchUp and imported those in their ARCHICAD model as (static) elements.
