New arteries for the Berlin Olympic Stadium

The Olympic Stadium in Berlin was constructed between 1934 and 1936 to the plans of the architect Ernst March. The complex includes a number of sports facilities, ranging from the Swimming Stadium to the well-known “Waldbühne”. Following the turn of the millennium, comprehensive reconstruction and renovation work began in order to update the complex to a modern sporting venue.
 
During the work, which amongst other things included the complete roofing over of the Stadium and its equipment with a new pipework system for fresh water, professional league football matches continued to be held at the Stadium – a thorny problem, which was however overcome with hardly any problems thanks to the perfect co-operation between all works and the excellent organisation.
 
Rich in tradition, the Stadium was finally handed back to the public at a ceremonial opening event in June 2004.
 
In accordance with the specifications of the Berlin water company, ductile cast iron pipes from Buderus were used for the fresh water pipework system, which also covers the fire-fighting requirements – a sound decision, which confirms the importance placed in Berlin on safety and durability. The cement mortar-lined cast iron pipes with TYTON^® connections withstand fluctuating internal pressures and also subsequent construction above them.
 
The planners had come up with something special for the Maifeld construction phase: since the old fresh water pipe had to be capped, a ring closure was required. A cost-effective and reliable emergency supply was provided by means of above-ground DN 250 ductile cast iron pipes with the BLS^® longitudinal positive-locking system. On completion of the work at the Olympic Stadium in the year 2004, the pipes were dismantled again without any problems before being used again for the permanent water supply of the whole complex.
