This article shows the results of the geomechanical characterization of the rock mass, to demonstrate the importance of generating field information on its geotechnical characteristics, according to the results of the geological and geotechnical conditions of the study site, since the intact rock does not represent the entire rock mass. According to the results of the geological-geotechnical condition of the site, it is divided into two study zones, a rock zone and a breccia zone, in which the procedure to define the geomechanical properties of heterogeneous materials is described, based on information of field and laboratory, data that will be of great importance to be able to evaluate the stability and the necessary treatments in the excavations of the later works.
