Eight floors of project offices have now been erected on the Quai du Louvre construction site. In conjunction with the requirements of the local Préfecture de Police, assembling this giant LEGO-like tower of portacabins was akin to a nocturnal “ballet”, watched with interest by passersby. During the busiest periods of the renovation project, the site “HQ” will house over 1,500 construction workers, combining staff living quarters, work areas and meeting spaces for the various project teams.
