Buildings on topography

Hi, I have a model with lots of buildings and a hill, created with contour lines that I “patched”. I would like to move all the concerned buildings on the hill, but I want them to remain vertical, which is why the command “FlowAlongSurface” does not suit me. What command or trick should I use to do that ? Thank you for your help.
