In 1930 the Indiana Bell building was rotated 90°. Over a month, the structure was moved 15 inch/hr, all while 600 employees still worked there. There was no interruption to gas, heat, electricity, water, sewage, or the telephone service they provided. No one inside felt it move. pic.twitter.com/07lf2hsgGT
