I do not work with Sketchup much, but the general idea (probably for any 3D editor) is to keep the origin/pivot/root of the model at the center (0,0,0).
Then at export/import it wold fall in place at the destination app at the correct location.
I just quickly looked it up. Try setting the Axis of the exported models to the center (right mouse click on the component).
There might be some other ways to do global change for all components though.
