Space in populated areas is becoming ever more restricted; as a consequence, more and more infrastructure is being shifted below the earth's surface. Both large and small projects require proven technical expertise and a great deal of experience in project management.

At our client’s disposal we have proven experts in the fields of geology, construction technology, logistics, material technology, construction management and organization.

During all project phases, an expert contact is personally at our clients disposal for all questions and requirements – even for interdisciplinary tasks.

Together with the client and his representatives, our engineers analyze the feasibility of a project and illustrate potential consequences. We set great value upon a personal contact with the client, whose requirements and satisfaction are of top priority to us at any time.

Customers and partners profit from well-established procedures and a short decision-making process. We react quickly to changes in unforeseen situations or circumstances, taking advantage of our network of specialists.
