Progress of works for infrastructure and equipment installation
July 2005

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. Progress until the end of 2004 has been reported previously. The pictures below illustrate some of the work done between January and July 2005. (Photos: M.
