   In 1930, the 22-million-pound Indiana Bell building was rotated 90 degrees over a month at a rate of 15 inches per hour, while 600 employees worked inside. Despite the slow movement, there was no interruption to the building's services, and none of the employees felt it move. #ConstructionHistory #StructuralEngineering
