PARALLEL SESSION C
C3 Complex buildings, construction and its safety related systems
Thu 3rd Oct 11h15 - 13h00
Hall 27 - Illy
Big Science constructions are examples of complex civil engineering, safety-important buildings typically characterized by high safety requirements to protect personnel, users, equipment, and surroundings against radiation, fire, gas, cryogenics, chemicals, heavy loads, and other hazardous items or situations. Many complex civil engineering techniques, safety regulations and practices have some commonalities in the Big Science organisations. They are typically subjected to the regulatory requirements of the country they are based in. The technical areas of particular interest are for example: complex civil engineering, health and safety activities and legislation, radiation protection and shielding, nuclear and non-nuclear hazards, waste management and disposal, radiological and environmental monitoring, licensing regulations, access control.

Agenda
Since beginning operations in 2008, the Large Hadron Collider at CERN has necessitated a revised lifecycle management approach for the CERN accelerator complex, driven by the long-time constants of its globally largest cryogenic system. CERN has implemented a schedule of long shutdowns typically every six years, lasting 2-3 years. I will outline the methodology for coordinating these planned stops and highlight key upgrades and interventions for the upcoming Long Shutdown 3, illustrating typical industrial activities involved.
The Tokamak Building Services Project is a Complex Engineering Project grouping several disciplines as piping, ventilation, fire detection, protection, instrumentation, and control. Design has been developed for 10 years with nuclear and environmental conditions specific to the ITER project. For the next 6 years, Fusion for Energy is planning to launch large procurement and manufacturing contracts for mechanical components and various equipment.
Critical personnel safety systems under the responsibility of Access and Alarms group of CERN Engineering Department include fire and gas detection, sprinklers, emergency evacuation, alarm transmission systems, access control, and personnel protection systems. Plans for tendering the supply of new systems including maintenance services for existing systems will be presented, as well as the strategic objectives and technical and organizational challenges of the future contracts.
European Spallation Source (ESS), in commissioning of the accelerator and final installation of the target and instruments, will be a user facility planning to host 1500-2000 scientist per year. In order to have a smooth access process for the scientist to the site and experimental halls, ESS has integrated its learning management platform with the access system. Development of specific training courses and integration of external training will be needed when the scientific user program starts (2026/2027) in order to operate the scientific instruments and experiments in a safe way.

FAIR
Civil construction of the FAIR Project comes to the end and the next step we are concentrating on is installation of the accelerator. Status of the different sub-projects, installation time plan, list of required documents to get permission to work on construction area, required external manpower and examples of works to be given to external companies will be presented in the talk.
