Berlin Brandenburg Airport (BER)
Germany's flagship new airport became a byword for megaproject dysfunction. A fire-safety system that failed its tests, chronic mismanagement, and repeated delays pushed its opening about nine years late and its cost to roughly triple the plan.

Narrative
The story
The ambition
Berlin needed one modern airport to replace its ageing Cold War-era fields and match the capital's ambitions. Construction of Berlin Brandenburg Airport began in 2006, with a planned opening in 2011 and an early budget of around two billion euros.
The rise
For a while it looked like a straightforward, if large, build, a signature piece of German infrastructure engineering on a confident timeline.
The cracks
Then the plan unravelled. The airport's fire-safety and smoke-extraction system was not built to its permit and could not pass the mandatory tests needed to open, and the project was dogged by chronic planning, management, and oversight failures, changed plans, dismissed planners, and an insolvent general planner.
The collapse
The 2012 opening was called off at the last minute, beginning a humiliating run of postponements. The airport did not open until October 31, 2020, about nine years late, by which point costs had ballooned from roughly two billion euros to around seven billion, and a pandemic had gutted air travel.
The aftermath
BER now operates, but its name became international shorthand for megaproject dysfunction. The failure was one of delivery and governance, not of the finished airport itself.
The lessons
A large, complex project is a management problem before it is an engineering one. When oversight is weak and no one owns the whole system, small defects, a mis-designed safety system, mismatched wiring, cascade into years of delay, and the cost of getting it wrong compounds every month.

What Went Wrong
Root causes
A safety system that failed its tests. The airport's fire-safety and smoke-extraction system was not built to its permit and failed the mandatory acceptance tests required to open. [2]
Chronic mismanagement. The project suffered persistent planning, management, and oversight failures, including changed plans, dismissed planners, and an insolvent general planner. [3]
Immediate trigger
The opening is called off. The scheduled 2012 opening was abandoned when the fire-safety system could not pass its tests, starting years of postponements. [2] [4]
Visible symptoms
Opening postponed again and again. The airport's opening was pushed back repeatedly over nearly a decade. [4]
Warning signs
Planning and oversight failures mounting. Persistent planning and management problems signalled the project was out of control well before the failed opening. [3]
