The "Alte Messe", Leipzig

The “Neue Messe” Leipzig has been completed, and has already passed its initial tests. The 235-acre site of the “Alte Messe” Leipzig is to be converted into a new city district. This required comprehensive conversion and new construction to the pipework system.
 
The first section of 250 m with two parallel DN 800 fresh water pipes had to be planned, put out to tender and completed within only 4 months. Although the course of the pipes necessitated a special solution, and although the pipes would have to be installed at temperatures down to -15 °C, the pipes were completed on schedule, thanks to the robustness of the ductile cast iron pipes.
 
The second section is characterised by two bridges. In one of these bridges, heat-insulated compensating cast iron pipes were used for the pipes. The pipes were installed using a special technique, so that the pipes and bridge can move independently of each other.
