Wowereit said.

The investigation into the massive delays in opening Berlin’s new BER international airport have begun. Managers have been fired and architects have been sued — but what about the capital’s mayor, who has led the prestige project since 2001?

…Hochtief executives quickly learned that the project had changed since Wowereit had been put in charge. Now the walls were to be covered with expensive walnut veneer paneling. The roof was to be built in a futuristic, free-floating design. And the granite used for the floors at other major airports, like Hamburg and Düsseldorf, was no longer good enough. Berlin’s new terminal had to have expensive Jura limestone floors instead.

…Wowereit, a member of the center-left Social Democratic Party (SPD), also recognized early on that the one person who doesn’t hold any share of the blame is Wowereit himself.

“I don’t see what concrete accusations should be leveled against the supervisory board,” says Wowereit.
