The capital’s airport, BER, has damaged Germany’s image as a land of engineers, medium-sized functioning craft companies and a trustworthy administration in the public perception. How did this come about?
An honest consideration also includes looking at the history of the various change requests that planners had to deal with over and over again in the 14-year construction phase: in addition to the political tug of war, over the location and equipment of the airport, about their role in the competition. With the other large airports in the republic, even before construction began, the dispute over whether the capacities would be sufficient to cope with the growing demand from tourists and businessmen.
Planners were constantly faced with new ideas from politicians, who were dealing with additional check-in rooms, docks and docks. Obviously, the fact that each expansion involves a lot of additional changes to the plan was ignored.
April 2007 – building permit Authorities review the construction application for nine months before granting the permit in April 2007. Originally only the central terminal and main pier are planned. The airport is scheduled to open at the end of October 2011.
The change requests were also not about aesthetic details, it was more than the very large in the literal sense: according to the original plans of the architect Meinhard von Gerkan from 1998, the terminal should have an area of 220,000 square meters. Fourteen years later, the usable space with a new dock in the south and one in the north, with additional mezzanines and commercial premises, totals more than 340,000 square meters.
July 2007 – Reorganization of the commercial area Subsequent building application for the reorganization of the commercial area. Additional commercial space with high fire protection requirements will be planned after security checks. The main pier will be extended to the north and a door for large-capacity aircraft such as the A380 is planned in the central pier area.
“By making changes, adding additional buildings, like these piers, the TGA became of course [technische Gebäudeausstattung] – among other things – with extensions, and that always had to be adjusted, ”said Manfred Körtgen, responsible at the time, describing the situation in 2016. Last but not least, Körtgen was referring to the fume extraction system, which is crucial for fire safety, whose capacity was no longer sufficient for the expanded area.
December 2007 – North Pier Planning Shortly before construction begins, the north pier will be planned and the main pier will be extended to the south. The extension will be approved in April 2008.
The desire of the chairman of the supervisory board, Klaus Wowereit, to create boarding bridges for the A380 had a particularly serious effect. That meant a huge additional structural reprogramming, but it should also bring additional exclusive sales locations near these doors. Several months later, when the relevant rental contracts were concluded, the entrance to the A-380 was suddenly built elsewhere, and the architects were forced to completely redraw the plans for the shops, vents, the electricity and water lines.
October 2008 – South Pier Planning Now the south pier will also be built in the course of ongoing construction work. The construction application is submitted in March 2009 and approved in August.
In hindsight, the effort seems downright ridiculous, but even then there was great skepticism that an A380 door would make sense. “My statement at the time was very clear: you can build there, but it will not be used for the next 15 years because the A380 will not arrive in Berlin forever,” recalled Thomas Weyer, head of technology at the time, in front of the investigation committee. of the House of Representatives. .
2009 – Layer change When Air Berlin announced that it would use the Berlin A380, the gate would be moved to the south side of the main pier, with far-reaching consequences for the entire planning of the building.
As of January 2010, new requests for changes were strictly prohibited. However, according to many participants, the airport management continued to order new things: spaces, rooms, lounges or commercial premises. Many wishes were even justified, after all, the airport’s business model fundamentally changed over the course of BER’s development period. But there was no thought about how the new requirements would be technically implemented, and how much time and money it would cost.
Level change Starting in 2008, the non-Schengen area will span the entire width of the second level of the main terminal. Passenger flows on the main pier must be reorganized, combined with considerable structural changes and effects on fire protection and escape route planning. At the same time, the passenger boarding bridges will rise to two floors. Now, the various planning stages, such as the draft, approval, and warehouse planning, overlap. Shell work is temporarily interrupted.
The myriad of plan changes barely matched the frantic pace of the supposed final outbreak. This meant that multiple construction plans were in circulation at the same time and craftsmen often placed orders that were out of date. Horst Amann tried to control the consequences of this systematic chaos caused by the management, the politicians, but also the urban planners and the construction companies, and after the spectacular failure of the opening in May 2012, he assumed the technical direction. Its inventory lists 120,000 defects, of which 4,000 are “approval relevant.” Overall, the Brandenburg State Audit Office found in hindsight that BER 2012 was only 56 percent operational.
2010 – Addition of pavilions The EU requires scanners to detect liquids in hand luggage. For this, two pavilions will be built. The opening of the airport was postponed until June 3, 2012.
Eliminating defects turned out to be extremely difficult. The smoke extraction system, for example, went down in BER history as a “monster” and had to be divided into several individual systems. The cable ducts had to be resized to be able to put the building’s electrical system into operation and also to meet fire protection requirements. Great effort was also required for the expansion of the piping system for the sprinkler system. Because suddenly a much higher water pressure was necessary to be able to supply the most distant places. Initially, however, the larger distribution pipes could not withstand such pressure. Similarly, each serious deficiency triggers a chain of later problems.
2018 – Start of construction of Terminal 2 As a lesson from the construction disaster with the main terminal, the airport company leaves the construction of the second terminal to a general contractor. Completion as planned in September 2019.
The current airport manager, Engelbert Lütke-Daldrup, had no ear for special requests under such conditions. Apart from the renovation work in 2018, it only commissioned Terminal 2 in order to cushion foreseeable capacity bottlenecks. As it stands, in this case at least, those involved have learned their lesson. They awarded the contract for the “turnkey” construction to the Zechbau company as general contractor. In fact, it was delivered on time.
