Subject aims expressed by acquired skills and competences
The course provides to a student with the excavated shallow subteraneous works which are carried out in exceptional soil conditions and by construction methods of underground facilities, which by their technical characteristics and its use are outside the standard tunnel works. Sucs as utility lines, pipelines, etc.. whose execution method is in principle distinct from the traditional methods of tunnel construction. The course includes as well a vertical shaft sinking technologies. The course goes on the knowledge of “rock and soil mechanics" and "underground construction". This course expands expertise in the issue, which doesn’t charge the study subject in the "underground construction". Geotechnical engineering graduate profiles and obtaines know how for the business of designing and implementing a wide range of shallow subterranean structures.

Summary
An classified overlay of methods to master the complex natural and geotechnical conditions for construction of underground works. Intervention methods to mitigate or to eliminate the unfarorable natural conditions. The technology to performe intervention. Powered shoring, shielding, extrusion, micro-tunneling, trenchless technology, freezing, kessons, dewatering, rehabilitation and reconstruction works and underground utilities. The course provides also forecasting methods to controle the development of negative effects and impacts in the rock mass. The second part of the course deals with the excavation of pits and shafts. It shows the designs for the site and excavating equipment in- outlet pit. It deals with conventional drilling and blasting excavation works, the problems of large-bore holes and wells. There is also an issue of blind digging trenches and blind shafts, deepening vertical holes, deepening and widening the pits. Knowledge and skills obtained by students completing the course: The student is introduced to the subject, it becomes familiar with the fundamentals, that are the relevant and constitute state of the art that is sufficient for the success of active work in that field and allows their self-improvement and development
