What we do
Tunnels, underground works and geotechnical engineering
Backed by decades of experience and highly trained professionals, we offer specialized services in tunnel engineering, injection treatment, subway works in general and geotechnical engineering. We provide innovative and efficient solutions that adapt to the different implementation phases and soil types, from conception to operation and maintenance of the projects in which we participate.
Transportation Infrastructure
We design efficient and sustainable transportation infrastructure that meets the growing demands of modern mobility. We develop civil works for roads, bridges, tunnels, railways and subways, connecting key points for the development and territorial cohesion of the countries where we are present. We design with the future in mind, with a vision focused on efficiency, safety and sustainability.
Hydroelectric and multipurpose developments
We work to achieve the efficient use of water resources and renewable energies offered by nature, developing hydroelectric projects, multipurpose developments, irrigation works and drinking water supply. Our multidisciplinary team focuses on making water, an essential resource, become a strategic ally for the development of the territory, creating the conditions for a better quality of life.
Operation & Maintenance
Solutions for the operation and maintenance of hydroelectric projects. Our approach ranges from the management of facilities in normal operation to critical situations (failures, incidents, sediment management, natural disasters, etc.). With a highly trained and experienced team of professionals, we ensure that projects operate safely, efficiently, cost-effectively and sustainably over the long term.
Competences
Conventional and TBM tunnelling
Conventional and TBM tunnelling
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.
Cavern and shaft construction
Cavern and shaft construction
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.
Underground facilities and systems
Underground facilities and systems
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
Tunnel safety
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.
Mining
Mining
Engineering services for the mining sector prioritize sustainability, ensuring that extraction processes have minimal environmental impact and make efficient use of resources.
Our commitment is oriented to implement advanced technologies and practices to safeguard both the surrounding ecosystem and mine workers. By emphasizing safety and eco-friendly solutions, our actions bridge the gap between resource demands and responsible stewardship of our planet.
Excavation support and ground improvement
Excavation support and ground improvement
We have many years of experience in the pre-treatment of weak rock or soft soil and the creation of sealing bodies in the protection of which tunnelling (conventional or TBM) can be carried out. Freezing, jet-grouting, systematic drainage and injections are examples of measures that we have planned and closely supervised during their realization and are therefore part of our core expertise.
Hydroelectric power plants
Hydroelectric power plants
We are specialized in all aspects of hydropower engineering. Our expertise covers of generation schemes, from high head to run-of-river, as well as pumped storage facilities. We cover the entire project lifecycle, from conception and design to commissioning, operation, and maintenance. This includes social and environmental impact assessments, civil and electromechanical design, as well as project appraisals and due diligence. We are currently engaged in significant pumped storage projects worldwide, supporting the transition to renewable energy sources.
Hydraulic tunnels and shafts
Hydraulic tunnels and shafts
Hydraulic and underground structures have been at the core of our business since the foundation of Lombardi. Thanks to our experience on many projects in Switzerland and around the world, we gained a deep understanding of the unique challenges related to the design, construction, operation and maintenance of hydraulic tunnels and shafts in a wide range of conditions. Our experience cover design of high pressure and low pressure system, including mechanized (TBM) and drill and blast tunnelling.
Dams and retention structures
Dams and retention structures
From the monumental Contra arch dam completed in 1965, one of the world's tallest and most slender, to the innovative RCC gravity arch dam of Arenal finished in 2021, dam engineering has always been at the core of our expertise.
Our comprehensive services cover the entire spectrum of dam engineering, including design from inception to completion, safety evaluations, rehabilitation strategies, and full-scale surveillance and monitoring solutions. In our team includes several federal dam safety experts appointed by the Swiss Federal Office of Energy.
