Introduction to the Technical Galleries Consolidation Program

The Technical Galleries Consolidation Program focuses on the remedy of existing issues and on the refurbishment of the galleries’ conditions and their related infrastructure to the extent reasonably possible. Drinking and firefighting water, as well as compressed air lines, are among the main priorities due to the bad conditions of the piping and the need to improve water quality. These networks have been enlarged gradually or partially discontinued depending on the needs. It is therefore necessary to have a complete review of all the usage and consumptions to define the new configuration and their appropriate dimensions. Dismantling and installation activities will be done by geographical areas and will follow a sequence to minimize disruption of services in the CERN complex. In addition, the Project will also aim at adapting the services to the present needs of the sites and at improving safety related aspects. This paper presents an overview of this consolidation with a particular focus on Cooling and Ventilation networks.
