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

The 1930 move of the Indiana Bell building stands as one of the most remarkable engineering feats in history.

In 1929, the Indiana Bell Telephone Company purchased the Central Union Telephone Company Building and had plans to demolish and build a much larger headquarters on the site. Architect Kurt Vonnegut Sr. had other plans. He suggested the building could be moved to make room for expansion.
@Miriamm How did they do sewage?
@newstik @Miriamm maybe a vertical segment at the pivot point, two or three if it needed to articulate, or they would need to have some flex in the pipes and reconnect every few days.
@newstik @Miriamm or even the power lines?!

@VincentWandersAimlessly @newstik @Miriamm

You can see cables and tubes hanging between the steel structure of the slider.

@Miriamm @hitsuyonai finally Wikipediaed that one to read a bit more. The architect who planned its movement was Kurt Vonnegut Senior.

Yes. That Senior to the more famous Junior. Wild.

@mxtthxw @Miriamm I guess if paid vacations were offered the building would have been moved empty. I wonder if anyone requested a 1 month unpaid vacation before the movement.
interesting, @Miriamm, were 9-story buildings today to cost £22M to build today I guess they’d do the same
@Miriamm Suddenly the Thunderbirds episode “Terror in New York City” looks less ridiculous.
@Miriamm They obviously stole this idea from "Dark City" 🎞️
@Miriamm This reminds me of that time Chicago decided to raise the whole city by fourteen feet.
@Miriamm Neat. I wonder why that was done.
@Miriamm so by 2030 we can move any building like that because humanity understood the buildings MUST be modular to be able to easily constructed/moved. Opps! We're another century away from that technology!
@Miriamm
Something similar was done in Stuttgart last year as part of building the new railway station.

@Miriamm and today they can't update anything without interruption.
@Miriamm and what was the reason?
@Miriamm This is one of the most beautiful things I have seen today.
@johnelalamo @Miriamm So that they could maintain telephone operations while the building was being moved to make way for other construction
