As in many European countries, a major part of the assets in civil infrastructure in the Netherlands has been built during the 1965-1975 construction peak. Many of the bridges from that period are at the end of their structural, economical and/or functional end of life. Asset owners are faced with the challenge to accelerate the future proving of these aging bridges in a safe, sustainable and efficient way. In this session we will explore the many opportunities digitalisation of asset management processes offers to cope with this challenge.

The replacement challenge of bridges is not an isolated task. Although highly challenging in itself, the concurrence of other tasks and interaction with externalities makes it really complex.  System-dynamic modelling can efficiently help us scrutinise different acceleration strategies under many different circumstances for robust and futureproof decision-making. In this workshop we will give a hint of how this is done for the bridge replacement challenge in the Netherlands.

Infrastructure networks are an essential part of our daily lives. They are so self-evident that we mainly notice them when they stop functioning. In this game, you are the manager of a transport infrastructure network, and it is your challenge to keep it functioning. You must monitor the ageing, performance, finances, satisfaction, and potential expansion of the network. To make it even more complicated, you will also face developments in the surrounding networks. Networks are increasingly interconnected, and developments in the rail network, for example, affect the highway network and vice versa. These interdependencies are often seen as difficult and complex but offer excellent collaboration opportunities. How will you keep your network alive?

A storm surge barrier is a movable barrier that can be closed temporarily to prevent the water levels behind to exceed certain dangerous levels. Typically, strict requirements are applied for the operational and structural reliability to guarantee the safety of the area behind against flooding. Meeting these strict requirements can however be challenging because of the sometimes limited maintenance windows, the infrequent operation and the fact that many barriers are unique-in-its-kind. Besides, as a result of sea level rise and socio-economic developments, requirements and hydraulic loadings can substantially change during the life time of the barrier. This session welcomes all topics related to the life cycle management of storm surge barriers, such as maintenance, asset and knowledge management, risk assessment and life time extension.

Many infrastructure assets are exposed to harsh conditions that influence the integrity of materials, limit accessibility for inspection, and create uncertainties in planning maintenance activities. Although the material conditions of buried infrastructure networks, such as energy pipeline networks, telecommunication cables, water lines, and sanitation systems, are generally simpler compared to large civil engineering assets, the key challenge for these networks arises from their invisibility. Disparate networks have been deployed over many decades, and are owned by different operators. Loss of data about locations and functional conditions hampers sound decision making about construction and replacement, while the underground environment becomes even more congested due to construction of new energy and broadband networks. This further complicates the situation and increases the risk of damage to existing infrastructure. This session invites professionals and asset managers for presentations and a closing panel discussion about how contemporary (digital) technology could support life cycle management of utilities. Technologies such as real-time network monitoring, pipe condition assessment, advanced detection and registration, and data-driven tools for utility strike avoidance are addressed and placed in the perspectives of authorities that are responsible for integrated life cycle coordination and ensuring public safety.

Resillience of infrastructure to changes in exposition and natural hazards during the lifecycle of a structure becomes an increasingly important issue. Ageing structures may no longer be used in a manner that was expected during design. Natural hazards, for instance due to climate change, may induce loads on structures that where not anticipated during design. Resilience is an important topic these days, and progress needs to be made to deal with the challenges of today and the challenges in the near future.

This theme session is co-organized by TNO and Rijkswaterstaat to explore together what the current major challenges mean specifically for Hydraulic structures and to what extent they can be transformed to major innovations or collaboration opportunities. Challenges are such as End of Life Decision Making, Climate Change, Digitalisation, or any other that you would like to bring to the table on hydraulic structures. We start with a short presentation on our on-going knowledge project, where we aim to create portfolio knowledge of navigation locks based on available data through utilizing the Semantic Web technologies to support prioritization for replacement and renovation program of Rijkswaterstaat. We use this as an opening presentation learn from colleagues working on abovementioned challenges and to make connections between organisations for further collaboration opportunities.

In this mini masterclass, we give a vision on the implementation of Life Cycle Management: because despite the fact that the added value of LCM is seen in managing organizations, the real change that is needed for this often does not materialize. In this masterclass, we will show positive practical experiences and discuss how you can get started with Life Cycle Management in small steps and how this contributes to pride in the maintenance management profession.
