“Located in Indianapolis, the Indiana Bell Telephone Company headquarters was moved 15 inches an hour, all while 600 employees still worked inside. There was no interruption to gas, heat, electricity, water, sewage, and most importantly, the essential telephone service they were providing to the city. A movable wooden sidewalk allowed employees and the public to freely enter and exit the building. The whole move took about a month to complete, lasting from October 12th to November 14th.”
