Renovation, management & maintenance
Cities will suffer massive strokes if we cannot use underground space more effectively and without hindering existing networks, such as metro-systems, and city life at street level. Building and renovating must be done whilst ‘the shop is open for business. We see that each country uses valuable time and money to develop their own strategies and options. Some ‘tweaking’ at a national level is always useful, but we could all benefit from more by sharing data, models, experiences, and options.

Tunnels: a heritage to regenerate. Italian EU funded program on refurbisment of roadtunnels
By TBA
Tunnels: a heritage to regenerate. In Italy, hundreds of tunnels, bridges and viaducts are needed to cross hills, valleys, and streams. Regenerating maintenance interventions on this important heritage and preventive maintenance of more recent assets have become urgent. No other country has so many. If we look at tunnels, Italy alone has half of all European tunnels, totalling 500 kilometres. However, this important heritage is ageing: most of the bridges, viaducts, tunnels and the motorway network itself were built between 1960 and 1980. In addition, the network has to cope with the stress caused by an average daily traffic of 40,000 vehicles per section (compared to 27,000 in France, for example), and with a particularly fragile territory and its hydrogeological instability. Suffice it to say that two thirds of the landslides in Europe occur in Italy and that this figure is likely to increase with the extreme events caused by climate change.It has become imperative to start a campaign of investigations on bridges, viaducts and tunnels considering the wear and tear caused by ageing, but also extreme weather events and the increasingly evident climate change, which affect road transport infrastructure. With support of the EU funds were allocated to start this campaign and Italy is now in the middle of this campaign. How far are they and what lessons have they learned so far?

Fitbit for tunnels: getting a grip for asset owners
By Mohammad Fotouhi & Michel Boutz
Due to settlements, loads, and environmental impact, damage occurs in tunnel constructions by material degradation. How this degradation progresses cannot yet be accurately predicted. In collaboration with the Centre for Underground Construction the Technical University of Delft is developing the Fitbit for tunnels: a way to monitor the condition of tunnel structures. Starting by identifying and selecting the critical locations and deteriorations in a tunnel. Next, develop, select, test, and implement sensors capable of detecting relevant changes in material properties. Collect the data generated by these sensors and interpret it using Artificial Intelligence. This session will delve into the Fitbit for tunnels.'

Skills & Resources
Facing challenges from personnel shortages to the intricacies of digital integration, the world of tunnel infrastructure stands at a critical crossroads between traditional expertise and the promise of digitalization—are we ready for the future it beckons?
Assetmanagement for tunnels
We see a widely spread ambition to become a more asset management organization instead of an organization focused on projects (either building or renovation projects). But what is professional assetmanagement for tunnels and what should be focal points for the upcoming decade?
