Bottrop landmark inspected by ZPP
The Prosper pit’s former waste dump is the location of probably the most uncommon pyramid in all the Ruhr area and the City of Bottrop’s landmark – the tetrahedron.
The impressive structure dating back to the year of 1995 is sporting a height of 50 metres while being built atop of 8 metre high concrete pillars. The 210 ton construction comprising steel and pipes has the shape of a four-surface pyramid, with a look that’s comparable to the mathematic Sierpinski pyramid. On the tetrahedron’s inside, there are three viewing platforms which are connected through stairways. Both the platforms and the stars were hanged down from the primary construction’s pipe structure via steel cables.
In order to make sure that this popular destination, which is located right at the Route der Industriekultur, can be safely visited in the future, ZPP Ingenieure has processed the main inspection following DIN 1076 as well as the cable inspections, as commissioned by Regionalverband Ruhr.
The result: nothing short of the most spectacular view over the Ruhr area is ensured!
