How to prepare for tunnel technology renovation?
Tunnels are equipped with a wide range of technologies, including safety systems, traffic control, HVAC, electrical systems, lighting, telecommunications, automation, software, and ICT systems.
The designed lifespan of tunnel technology is approximately 30 years, but the actual lifecycle varies between 10 and 30 years, depending on the technology. Major technical renovations are typically required every 15–20 years.
Many of Finland’s road tunnels have already reached or are nearing this point.
Tunnel renovations must take into account:
- New and updated regulations, standards, and guidelines
- Leveraging new technologies, innovations, and proven practices
- Thorough planning (e.g., condition assessments, preliminary studies, general planning, system interdependencies)
- Gaps in existing documentation
- Adequate scheduling and preparation
- Environmental factors, such as weather and limited space
- Future renovations.
Renovation project particularly benefit from expertise in tunnel environments and experience from previous projects.
