Stuttgart 21 has become notorious for delays and budget overruns, placing it on an infamous list alongside Berlin’s airport and Hamburg’s Elbe Philharmonic Hall.
The initial €2.5bn price tag has ballooned to €8.2bn. In 2016, Germany’s Bundesrechnungshof, the country’s highest government audit authority, warned costs may rise to €10bn and chided Merkel’s government for “serious shortcomings” in its oversight.
The FT can now reveal that in 2016 Deutsche Bahn’s compliance department received repeated warnings from inside the company that a significant part of the cost inflation was caused by glaring mismanagement and suspected corruption.
From the issues of the last years with Company governance, the famous Berlin airport issues to the old manual processes at the Rathaus, never seen it... Maybe in the Swiss-German cantons or Austria?
The original plan looked very different from what was later realized. Which was a significant driver of the cost.
Just for fun, lets compare it to the Sydney opera house:
Elbphilharmonie, original projected cost: 186 Mio EUR
Elbphilharmonie, final cost: 866 Mio EUR
So in the end, 4.65x the projected cost and 7 years late.
Sydney Opera house, original projected cost (inflation adjusted cost in parens): 7 Mio AUD (70 Mio EUR)
Sydney Opera house, final cost: 102 Mio AUD (632 Mio EUR)
So in the end: 9-14x the projected cost and 10 years late (depending on if you compare based on the inflation adjusted costs).
Therefore, in comparison, not that dissimilar.
After ousting Jorn Utzon they tried to finish it on the cheap and running roughshod over the original plans they wound up with a totally iconic building (from the outside) and a terrible theatre and concert venue on the inside.
I haven't seen the Elb Philharmonie. But from what I heard it must be a fantastic venue in every respect.
