the contracts concern the construction of a set of 13 buildings, representing more than 200,000 square meters of surface in the work. The overall lead time for the completion of the work is approximately 5 years. These works are allocated both geographically, in 4 blocks, and technically, in macro-lots and separate lots (see presentation grid of the lots in the Ccap). The general earthworks (lot 001) were the subject of an autonomous procedure. Lots beginning with “0" designate transversal lots concerning several geographical blocks. The project integrates a voluntarist environmental approach of the CHU (energy performance, geothermal, low-nuisance site...), and a professional integration process for people in difficulty in cooperation with Nantes Métropole

relates to the implementation of medical fluid and special gas installations for buildings C, D, E, F and L (block 2) comprising the production and distribution of vacuum (medical, laboratory, dental, mortuary) and compressed air (medical, laboratory, industrial), the distribution of oxygen, nitrous oxide, nitrogen (liquid and gaseous), and carbon, the network for the evacuation of anesthetic gases. The entire installation has about 10,000 sockets or keying devices
