The Herrenknecht service solution
The Dragages-Bouygues JV and Herrenknecht launch a joint pilot project in the form of the new method for building cross passages. What’s more, the structures need to be realized during tunnelling in the large tunnels. Accordingly, project and realization planning as well as technical design are marked by extensive engineering expertise and experience. In order to ensure success even during tunnelling, very experienced Herrenknecht personnel is on site at all times who are also in regular contact with experts in Schwanau. For each shift, Herrenknecht provides two supervisors and four service technicians as well as a TBM operator. Direct communication and short coordination routes ensure that a steep learning curve is achieved even during the course of the initial cross passages. Average construction time for each cross passage is just under 21 days, which complies with the requisite parameters. Proof of the fact that permanent service support is a decisive factor for handling pioneer projects.
In-depth engineering know-how and experienced service personnel permit top results when combined with newly-developed pioneer technology, even for complex projects.
Direct communication on site helps to accelerate solution processes, thereby ensuring steep learning curves to the advantage of the project.
Thanks to good partnerships between construction companies and machine manufacturers, new technologies can tap future areas of application.
