At the GSI Helmholtz Center for Heavy Ion Research in Darmstadt, one of the largest facilities for top international research is being built on an area of about 150,000m2 - the particle accelerator facility FAIR (Facility for Antiproton and Ion Research). In an underground accelerator ring tunnel with a circumference of 1,100 meters, scientists from all over the world will be given the opportunity to investigate findings about the structure of the universe with extraordinary experiments. Approximately 25 buildings will be erected on the site for the operation of the particle accelerator. For this international mega construction project, a construction schedule had to be developed in which structural engineering, civil engineering, accelerator development and construction as well as the scientific experiments are closely interlinked.
The entire fire protection, from planning to implementation, comes from MULTIMON. A fire protection system with high-pressure water mist technology will be installed in the beam tunnel and in the supply tunnel with intermediate floor. Following the physical test setup, only water supply lines are provided in the radiation tunnel, but no independent water supply. In the buildings with laboratories for application research, a modern gas extinguishing system will be installed to ensure safety for people and objects without affecting the elaborate experimental arrangements. The total installation time is scheduled for six years in coordination with the trades to be installed at the same time.
The multidisciplinary team of the FAIR project executing agency sets standards in terms of site organization, occupational safety and environmental protection.
Selected technical specifications:
Total fire protection High-pressure water mist system (HDWN) Approx. 4000 sprinklers Approx. 20 extinguishing control panel Six-year construction period.
