Berlin's Most Notorious Construction Sites (...besides the BER,that is!)

... notorious,because they were all due to be completed years ago, and yet none of them are!

Pergamon Museum (estimated completion date: 2021;architect: David Chipperfield)

State Opera (estimated completion date: 2017/ 18)

National Library (estimated completion date: 2016/ 17)

Barenboim-Said Academy (estimated completion date:  2016/ 17; architect/ interior: Frank Gehry)

James Simon Gallery (estimated completion date: 2017; architect: David Chipperfield)

What's interesting here is, that every single construction site is undertaken by the City of Berlin or the Federal Republic of Germany or jointly by both. For some time now, I've been observing the progress on private construction sites as well as public ones (such as the ones above) and guess what - those that are privately funded are usually completed on time while the public ones tend to be delayed by years. As to why is anyone's guess ...  ...
