If no photos for One Chicago, you can probably dig up photos from Block 37 or River East Center, both of them used the top-down technique.
It's a slow process, because everything has to be dug up with small equipment (bobcats and mini backhoes) and then hauled to the surface one bucket at a time through holes in the floorplates above.
