Frankly, ArchiCAD does not need SketchUp. While the modeling abilities in SketchUp are nice, they don't apply well in the BIM model from ArchiCAD. I would recreate the building with native ArchiCAD elements rather than by importing them from a SketchUp model.
I agree with Stefan as far as importing buildings. Model them over in AC to get a proper model.
But, SketchUp is really useful for creating entourage visually (e.g., furniture, model embelishments, etc) - in which case save as 3DS (from SketchUp Pro) and use ArchiCAD's 3DS-In plugin (downloadable from Goodies) to bring the model in as a GDL object.
Also, the SketchUp-Google Earth connection is incredibly useful for anyone trying to place their model in a site context involving mountains in order to get proper sun shadows / sun studies.
I've lived in ski communities for the last 20 years. In each case, if we omit the mountains, then there is no way to get proper shadows. (Missing the trees matters too, of course.) Modeling the site terrain for the building site isn't enough.
The Google Earth - SketchUp connection lets you grab Google Earth 3D terrain, with image mapped onto it automatically...pan Google Earth, capture again, repeat...until you have as much surrounding terrain as you need. Low polygon count, but elevations are good enough to create reasonably accurate shadows on your building and site ... and decent approximations of views from windows, etc.
But buildings? Nope - model them in AC as Stefan says (unless they are simply the context of your model - that is neighboring building masses).
