This service concerns in firm tranche the realization of a dimensioning study at the Avant-Projet (Avp) level of a set of structures for the protection of property and people living near the Bossons torrent in Chamonix, namely the recovery of 3 bridges, the increase of the bed gauge on a linear of about 400 m and the realization of an embankment on about 75 ml. It should be noted that the creation of the embankment dike corresponds to the reinforcement of the Bossons which is existing but in a very degraded state and of insufficient height. The service also includes as an option the realization of the other missions of Moe until receipt of the works and the various regulatory files useful to the various development projects. The estimated overall cost of the works is estimated at approximately 900 000 euro(s) Ht at the stage of preliminary studies
