The Friedrich Engelhorn high-rise (called E100 in the BASF building notation) was a 101.63 m high building in the main plant of BASF SE in Ludwigshafen am Rhein . It was completed in 1957 and named after the BASF founder Friedrich Engelhorn . From 2013 to the end of 2014 it was demolished. Since the building was a listed building, the authorities carried out a particularly thorough examination of the demolition application.
Until the completion of the Bayer skyscraper in 1963, the Friedrich Engelhorn skyscraper was the tallest building in Germany, and until it was demolished it was one of the 100 tallest buildings in Germany .
history
The design for the skyscraper was the result of a competition held by BASF in June 1953. Five architectural offices were invited, including the Düsseldorf office Hentrich & Heuser (continued as Hentrich & Petschnigg after Heuser's death in September 1953 ). The design by Hentrich & Petschnigg, which was awarded the first prize, was essentially the work of four just graduated architects Fritz Eller , Robert Walter , Richard Janeschitz and Ulrich Kölsch, who were freelance workers at Hentrich & Petschnigg.
The foundation stone was laid in December 1954. Documents , building plans , coins and a bottle of Palatinate wine are still in the foundation . On March 21, 1957, the 28-storey building (20 office floors, 4 tower floors, 1 top floor, 2 basement floors, 1 ground floor) and 102 meters high was inaugurated.
During the renovation of the high-rise in 1996, the mosaic stones were replaced by a curtain wall made of aluminum and glass. In 2004 the new BASF logo was attached to the tower floor. A complete renovation of the building over several years began in 2011. To this end, the entire workforce including the Management Board moved out in 2012. But then it was determined that the renovation would cost a three-digit million amount, also because the masonry was contaminated with the pollutants asbestos and PCB from the construction period . That is why BASF decided in October 2012 to apply for the demolition of the high-rise, which was approved in June 2013. The floor-by-floor demolition began on August 12, 2013 and was completed at the end of 2014.
construction
The construction was one of the first high-rise buildings with a modern concept, implemented by the architects Hentrich & Petschnigg. The reinforced concrete skeleton with glass mosaic curtain walls rested on pilots . Two consecutive, overlapping, rectangular panes contained the office space and were connected to one another by a glazed core. This arrangement reduced the traffic area to a minimum. The dissolved attic was closed by a flight roof. The glazed entrance hall, which had been demolished in the meantime and was formerly attached to the south side, had a roof that was curved in the style of the 1950s and supported by steel supports encased in mosaic.
