Hamburg’s concert hall on the Elbe was first planned to be finished in 2010. The city’s share of the cost was first calculated at 77 million euros. In the end, construction cost about 866 million euros, and the first concerts took place on 11 January 2017. A committee of inquiry of the Hamburg parliament examined what had gone wrong. It found that when the work was put out to tender in 2006 and the contract was signed in 2007, the planning noch nicht weit genug fortgeschritten gewesen, had not yet advanced far enough.
