Grace Ford Salvatori Building 

Side facing the track & field is the only door with the automatic door opener, and the button is on the inside of a column. You have to press it a few times to get it to work and only one door opens (door is kinda small). There is a button inside the building to open the track-facing door as well. There is another door with buttons on the same side of the building, towards SGM. There are many ramps. On the back side of the building (facing Viterbi), there is a ramp, but no buttons to open back doors.
