Lombardi Austria

Our core competence builds on the great Swiss tunnelling heritage. Risk management in tunneling starts with the systematic analysis of the geological and hydrogeological fundamentals, which leads to the detailed representation of ground models (Baugrundmodelle). The relevant hazards (Gefährdungsbilder) can be easily identified on the basis of the ground models and possible concepts for measures can be than drawn up. This systematic approach leads to a robust excavation design even under the most difficult conditions in coventional or mechanized excavation.

The subsurface is gaining more and more importance for large and often complex underground facilities, be it for hydropower plants or research facilities. For the design of caverns with large heights and widths, as well as deep shafts, the detailed study of geotechnical conditions and a deep understanding of the principles of rock mechanics are indispensable.

Complex underground facilities for research or community service facilities are part of our core business.

We are involved in the design of numerous laboratories for scientific use: it is also a mission for our company to contribute to the scientific community. We have historically been involved at Cern in Geneva (1981) and for the sub-nuclear physics laboratories under Gran Sasso (1985). In the recent years (2016-2022), we have been the leader of “HL-LHC Point 5” infrastructure design at Cern (Preliminary Design, Final Design, Detailed Design, Tender Design, Preparation of the tender based on FIDIC Redbook standards.
We are also involved in high-voltage underground connection projects.

Tunnel safety measures are primarily aimed at preventing accidents and secondarily at minimizing the effects of an event. Both aspects are taken into account as decisive design objectives in the planning and realization of the operating and safety installations.

• Integral tests and fire tests allow the effectiveness of the installations to be verified.
• Regular training of operating and emergency personnel, audits and event simulations ensure a high level of personal and building protection.

For example, we carried out the electromecanical equipment of several important tunnels in Switzerland and are currently heavily involved with the equipment of the entire Gotthard Road tunnel system. In India, we are currently in charge of the equipment design of a new urban tunnel in Mumbai, as well as of various rail tunnels in the north of the country.
