Progress of works for general infrastructureNovember / December 2004

Following the completion of the main civil engineering works and some additions to the underground structures (trenches, holes for air-cooling ducts, etc.), the works for the infrastructure (air handling, water cooling, electrical installation) started in July 2004. The pictures below intend to illustrate some of the progress made since then. (Photos: S. Lebrun, M. Wilhelmsson, K. Elsener)
