I saw a ZDF TV docu about Berlin Airport last year. Very low-ceilinged halls and rooms means the cannot integrate gas purge and fire safety pipes and equipment. It seems so serious that an international experts in the docu suggested to rebuild parts of the airport buildings. And it seems weird that the airport will be already too small for the passenger traffic in 2017. Given that it should replace the former largest airport in the world Berlin Tempelhof and two other airports near Berlin. Several politicans have already been replaced because of scandals and multi-year delays. Shop space was already leased in ~2011 and employees already waited to begin their new work. It seems really a lot has gone wrong with BER. It would probably be cheaper to blow up the already too small buildings and build completely new ones or reactivate Tempelhof.
