This contract consists of the development of a bivouac site for the reception of the public at the top of Savane-roche Virginie. This sensitive natural site, at an altitude of 138 m, in the state forest of Régina Saint-Georges, is accessible by an already developed path. The bivouac area will be made up of wooden structures that blend into the landscape, called "centipedes". The structures are assembled, in kit, in the workshop and are easily dismantled. Each part can be changed independently from the rest of the structure. The site must have the equivalent of 22 beds divided into 4 modules of 3 places and 5 modules of 2 places. The kit structures will be transported by helicopter and then installed at the top of Savane-roche Virginie. (EXPIRED)
