“Fire protection system,” fire safety system. The most expensive failure at Berlin’s new airport, blamed for over a trillion euros in unplanned costs and delays of more than a year. It seems the Willy Brandt airport’s architects decided traditional smoke extraction systems, in the form of vents and fans hung under the airport’s ceilings, where smoke actually rises to, would put too many ugly ducts in view. They decided to run the smoke extraction system under the airport’s flooring, necessitating extra-powerful fans and kilometers of conduits for the extra cabling required. But apparently construction proceeded too rapidly while these design decisions were being taken, and communication with the construction side was poor, because the in-floor smoke extraction system was built without conduits for all its cables. The airport’s floors are now being torn up to create these. A new top manager has been brought in, with experience from large projects at Frankfurt/Main airport. He says things are going to work out fine.
A similar jaw-dropping story happened when the well-known Kassel-Wilhelmshöhe train station was built.
