Geotechnics & engineering geology
Geotechnical engineering combines elements of earth science, construction and mining. Tunneling projects, slope stabilization or site investigations are typical areas of application.

Summary
Applications of Geotechnics
If there is to be building underground, people who are familiar with the mechanical properties of the ground or rocks are deployed: No Gotthard railway tunnel without specialists from the field of geotechnics or engineering geology!
Examples of typical geotechnics or engineering geology applications:
- From simple geotechnical site investigations for the construction of a single-family detached home, through to highly complex geotechnical investigations
- Tunnel construction
- Construction of a landfill site or a radioactive waste repository
- Slope stabilization
- Dam construction
- Rockfall barriers
- Construction and maintenance of mines and quarries

The GEOL_BIM project
Building Information Modeling BIM is the future of digital construction. BIM is changing the planning and work processes and requires a large amount of quality information from a wide variety of sectors to ensure successful implementation. The challenges of Big Data extending even beyond the geology scene are met in BIM.
Within the scope of the innovation project GEOL_BIM, spatial geological data (3D models, GIS world) will be supplemented with detailed building information (BIM world) in digital construction. Ziel des Projektes ist der Import eines geologischen 3D-Modells in eine BIM-Software und die Erstellung geologischer Profilschnitte mit Angabe der Prognosegenauigkeit an einem beliebigen Punkt.

Who is who
Geotechnical engineering is taught in Switzerland at universities. These also participate in major projects. Otherwise, mostly private geology and engineering bureaus which are specialized in geotechnics, carry out the work.
The Institute for Geotechnical Engineering deals with soil and rock mechanics, clay minerals, geotechnical engineering and geo-environmental engineering. The institute is responsible for teaching and research, has highly specialized laboratories and field equipment at their disposal and offers various services.

The group for Engineering Geology is part of the Geological Institute of ETH Zürich. It researches the hydraulic and mechanical processes in fractured rock masses. The studies do not remain mere pure research, but are implemented daily in the fields of tunneling, natural hazards, geothermal energy or the sustainable use of groundwater.

The Laboratory of Engineering and Environmental Geology is part of the School of Architecture, Civil and Environmental Engineering ENAC (Faculté de l'environnement naturel, architectural et construit ENAC). It sets priorities in the natural resources of groundwater and geothermal energy, as well as in natural hazards, groundwater contamination and tunneling.
The Geozentrum Burgdorf is a collaboration between the Bern University of Applied Science
(department Architecture, Wood and Civil Engineering) and the Institute of Geological Sciences of the University of Bern. The laboratories of the Geocenter for Geotechnics and Engineering Geology support the teaching and research activities of both institutions and carry out a variety of material tests.
The institute is part of the Department for Environment Construction and Design of the University of Applied Sciences and Arts of Southern Switzerland (SUPSI). It deals with the management and protection of the environment and its resources. Its areas of expertise include geology, geotechnics, hydrology, hydrogeology and geomatics.
Innosuisse, the Swiss agency for the promotion of knowledge-based innovation projects for the benefit of the economy and society, approved the application for the funding of the GEOL_BIM project in December 2019. The Swiss Geological Survey at swisstopo and the University of Applied Sciences and Arts Northwestern Switzerland FHNW, under the direction of the Swiss Association of Geologists CHGEOL, are responsible for carrying out the project. Notable federal offices, organisations and companies are involved in the GEOL_BIM project.
Data
Several federal agencies and cantonal authorities provide the public and private sector with basic geotechnical data: groundwater data, borehole profiles and other types of data can be obtained online at the respective cantonal offices for the environment.
The Swiss Geological Survey
The Swiss Geological Survey collects and archives unpublished geological documents, digital data (e.g., from seismic recordings) and samples (in particular drillhole samples) useful for national geological investigation. It makes this geological information available professionally.
Cantonal Centers
For example, on many cantonal web portals, groundwater data, borehole profiles and much more may be obtained. Map viewer of the cantons.
Swiss Geotechnical Commission (SGTK)
The SGTK (now the Georesources Switzerland Group), since its foundation in 1899, has been compiling documentation, reports, databases and maps in the field of geotechnics in Switzerland:
