Since 3G was founded, we have worked closely with university research institutions within the framework of international projects. For this reason we also actively participate in training programmes. Here we offer seminars lasting one day or several days on which geological and geotechnical knowledge is conveyed, especially in the underground construction sector. The focus is increasingly on conveying knowledge via on-the-job training, in other words we develop innovative methods and solutions together in practice during projects, and then also implement them.
