Worth knowing about the background of, the independent information, working, and learning platform for the underground infrastructure.


UNITRACC (Underground Infrastructure Training and Competence Center) is an independent information, working, and learning platform for the underground infrastructure.

"The Entire World of Underground Infrastructure" is one of our guiding principles. The urban buried infrastructure for supply and disposal are lifelines which decide on the quality of life and sustainability within - not only - the great cities. The significance, complexity and the immense financial value of these networks make a sustainable operation, maintenance, structural extensions, and rehabilitation mandatory. provides expert knowledge, tools, and instruments, as well as the contact persons for these tasks and problems.

As a result, knowledge transfer is an important topic for us and we have put this into practice with innovative online solution for learning and teaching. The internet provides time and local independency for learning and working, which is definitely a great advantage compared to conventional information-, learning- and working-possibilities. Web-based knowledge transfer offers variety, transparency and relevance, especially through the possibilities of media-specific contents and didactic presentation.

What is the goal of

Knowledge creates professional competence and increases the national and international competitiveness. The learning and identification of expert knowledge and working methods is more than ever mandatory. Professional duties and responsibilities are getting more and more complex due to the innovative technical developments. Further education and training has to be adapted to these needs and developments. has responded to this with individual learning- and instruction profiles.

Furthermore, offers time and place independent expert knowledge, which consequently represents an "All In One Hand-solution" for the support of the working- and learning process. This service is adapted for target groups and specific problems. In detail this means:

  • Creating a professional competence by providing national and international state of the art technical information systems and scientific expert knowledge - this can be found in the area "KNOW-HOW".
  • Knowledge compatibility of further education and training by providing teaching material for technical colleges, training centers and universities- in the area "E-LEARNING".

In addition, the MEDIATHEK offers a comprehensive collection of pictures, animations, and videos on the various construction and renovation procedures that invite you to browse and search for specific objects.

For whom is constructed?

Whether individually or job-related: The underground infrastructure fascinates you too? Our platform welcomes everyone who is interested in underground infrastructure with all associated cable-, gas- , water-, sewage-networks and much more. was mainly developed for national and international experts who are interested in the construction, operation and maintenance of pipeline networks, as well as for teachers, instructors and students. can be used as a foundation and guideline for finding the solution for a variety of theoretical and practical problems. Furthermore, is also a business solution for certified engineers and technicians who work in pipeline construction and maintenance. supports and assists trainees, students, participants of educational courses and qualification procedures during advanced training and continuing education, as well as teachers and instructors in educational institutions, colleges, and universities. Town councils, local authorities, and private companies who own and operate public supply and disposal networks are hereby addressed.

Who created is a product of Prof. Dr.-Ing. Stein & Partner GmbH and visaplan GmbH – both based in Germany. These two companies actively deal with topics of web-based knowledge-collection formats and placements. visaplan GmbH develops methods and concepts, such as web-based content management systems and web-based knowledge platforms, e.g.

Prof. Dr.-Ing. Stein & Partner GmbH

The technical and professional know-how is provided, amongst others, by the engineering company Prof. Dr.-Ing. Stein & Partner, Germany. The international relevant technical compendiums "Rehabilitation and Maintenance of Drains and Sewers", "Trenchless Technology for Installation of Cables and Pipelines" and "Der begehbare Leitungsgang" ("The Accessible Utility Tunnel") originate from here.

visaplan GmbH

The company visaplan GmbH is responsible for the digital media integration, 3D-construction, visualization and animation, digital video productions and editing, multimedia, CD-ROM and web-authoring.

The history of

The idea and concept of was born in 1996. Fascinated by the possibility of using multimedia technologies for transferring knowledge in the area of sewer and pipeline construction, Mr. Dr.-Ing. Robert Stein, CEO Prof. Dr.-Ing. Stein & Partner GmbH and CEO visaplan GmbH, developed the so-called S & P online concept. At that time, most corporations viewed the Internet as a non-relevant niche phenomenon. The central point of his vision was the desire for a technical triad: Multimedia-based specific information with computer-based decision support systems and the internet as an up-to-date platform.

These three ideas were combined into the in the year of 2001. This was made possible due to the financial and intensive support of the German Federal Ministry of Economic Affairs and Technology and the federal state North Rhine-Westphalia (with a grand total of 4.5 million euros) as well as the Association of the German Building Industry.

Today, is a leading global information teaching, learning and working platform that enables knowledge transfer and the coordination of education and training related to underground infrastructure. It is also a central place for international exchange of information and experience for everyone who is interested in pipeline construction, maintenance, and management. Among other things, the success of is displayed by several prizes and awards like the European E-Learning Award "eureleA 2004" and the "No-Dig Award 2005" of the International Society for Trenchless Technology.

LOGO TTC / At the end of 2016, a new competent partner for the American market joined the team: The Trenchless Technology Center (TTC) of Louisiana Tech University in Ruston, Louisiana (USA). In cooperation with local experts and under the leadership of Professor Dr. Tom Iseley, the individual e-learning modules have been gradually adapted and revised to suit American standards and guidelines.
