Tunnel engineering

The wide range of tunnel-engineering solutions provided by Ramboll are increasingly valuable, as tunnels are used more and more to connect people and places. Our areas of expertise include urban metro systems, railway and road tunnels we are currently working on the Fehmarnbelt immersed tunnel project, a fixed link between Scandinavia and Central Europe. We also work on engineering tunnels at a smaller scale, such as those designed for pedestrians and cyclists, as well as for all kinds of utility systems.

Our services

Ramboll undertakes all project phases for tunnels, such as:
  • Feasibility studies
  • Conceptual design
  • Preliminary design
  • Detailed design
  • Tendering and contract
  • Supervision
  • Operation & maintenance
  • Independent checking
The services can include the initial investigations of geological and environmental conditions at a tunnel site, followed by rock mechanical calculations and a resulting initial tunnel design.  Design of ventilation, fire safety and installation of mechanical and electrical components can be undertaken. Ramboll can undertake supervision including the management of operations and maintenance, and routine or periodic tunnel inspections using Supervisory Control and Data Acquisition (SCADA) systems of an entire tunnel engineering project.
Ramboll provides high standard, multidisciplinary solutions for all types of underground structures. Furthermore, we are experienced in special disciplines, such as tunneling under and close to existing structures, permanent diaphragm walls, top-down methods, etc. The preliminary investigations involve a range of different disciplines. Frequently, a thorough preliminary investigation is the key to a successful project. Our tunnel engineering work covers investigation, preconstruction, and construction phase investigations. These stages include primary site exploration, detailed surface investigations, detailed sub-surface investigations, on shore and off shore geophysics and tunnel mapping.
