Improving the performance of our assets over their life cycle relies heavily on the timely availability of accurate, actual and accessible data. There are many new developments in data technologies that are helping us to overcome the challenges on data management improving the way we manage the performance of assets over the life cycle management.

Durability is the ability of a physical product to remain functional, without requiring excessive maintenance or repair, when faced with the challenges of normal operation over its design lifetime. Structures will age in time, and at some time need maintenance or need to be replaced. In Life Cycle Management durability issues need to be addressed. Ageing leads to risks an cost over the life cycle. Optimal maintenance and repair strategies deliver optimal performance over the life cycle.

Civil infrastructure often bears functions related to flood risk reduction, water management, navigation, mobility or a combination of those. Existing infrastructure generally has long technical life spans, but has not been generally designed to adapt for changes in use, climate or regulations. Currently, a considerable part of the (water) infrastructure is approaching the end its service life and large investments are required for rebuilding, adjusting, renovation and maintenance.

Resilience in Life Cycle Management deals with resilient life cycle engineering, resilient life cycle design & construction, and resilience in the operation and maintenance. Central issue for this topic is: “How to anticipate possible future changes and extreme events (Life Cycle Risk Management).”

Traditionally, fixed design horizons are used in the design and maintenance. But, along the way the actual ‘optimal’ life time can be affected by external developments like climate change and socio-economic changes or transitions. This session discusses on how to deal with such (deep) uncertainties in the design?

This theme session will focus on the life cycle assessment and management of water infrastructure like dikes, bridge piers/piles, sluices, locks, retaining walls, sewage and drinking water, harbor infrastructure, reservoirs and dams, etc; The focus of their management is shifting from condition and risk management, to predictive and adaptive management and from asset level to system or regional level. These trends require the search for smart solutions from technical, financial and governance point of view, to meet present day adaptive, societal and environmental requirements. The objective of this theme session is to exchange and discuss the best approaches and innovative practices in Life Cycle Engineering in water infrastructure.

Structural reliability deals with the probability of failure of structures over the remaining life. Structural reliability may change over time due to changes in the loads on the structure, changes in the strength of the structure, and changes in the remaining life time of the structure. Reliability can be assessed more precisely if uncertainties in loads and strength over time are known better. Structural reliability plays a major role in design guidelines, aiming to keep risks over the life cycle of a structure within accepted boundaries. For ageing structures structural reliability needs to be managed. Changes in loads and strength over time need to be monitored. Uncertainties need to be assessed and managed. Reliability of existing structures need to be evaluated over time, and sometimes re-calculated. Investment in managing the structural reliability need to be evaluated on costs and benefits over the life cycle.

In this workshop, we distinguish two distinctive pillars of the Life Cycle Management of the Structural Reliability of assets, both with a dedicated session. This theme session focuses on the Modelling

Sustainability is a relatively new perspective to Life Cycle Management. Infrastructure should be designed, constructed and managed during their life cycle in such a way that the harmful impacts for the environment are minimized. Key aspects that should be considered within sustainability assessment are for instance use of resources, energy and land, emissions to air, water and soil, pollution of environment by noise, vibrations and waste, and impact on species and ecosystem and society.

Road networks often have long life cycles. Roman road systems constructed 2000 years ago can still be recognized in the landscape. System- and network requirements may however change over time, so systems and networks also need to be adapted during their lifetime. Keeping systems and networks up to date and fit for purpose, especially on the long term, is a challenge. Lack of long term thinking will result in badly functioning, not fit for purpose, or even unsafe networks.

The Life Cycle Management of systems and networks typically needs to deal with system optimization and network management over the life cycle, while anticipating diverse challenges like climate change and aging.

Implementing Life Cycle Management in organizations and processes is a challenge. Traditional steering principles on short term issues are deeply in our cultures. Even tough the awareness on life cycle thinking grows, change is still hard to make. Both human factors and lack of technical tooling to support the changes play a role. New management concepts are needed, supported by proper tooling to make that change.

Asset Dynamics for Predictive Life Cycle Management – Case Study ‘Integrated Bridges and Circularity Model’

The Dutch Highway Agency (‘Rijkswaterstaat’) manages and maintains the dutch highway infrastructure. More than 5000 bridges and viaducts are part of this network. Those bridges are mainly build last century and the challenge for the future is how to keep them in shape while the demands are changing. It is expected that more and more projects for replacement and renewal are needed, with a huge impact on the capacity of Rijkswaterstaat and of contractors and on the needed budgets.

Copernicos Groep is now working on a Asset Dynamics application to create a model for Rijkswaterstaat with which it gets more insight in what strategies are needed to balance the need for upgrading the bridges, available capacity/capabilities, budgets and impact on the primary functions (traffic flow) and the environment.

Rijkswaterstaat also recognizes that a project for replacement or renewal of infrastructure gives the opportunity to innovate and become more sustainable: to apply the concept of circularity i.e. re-use parts or material of existing bridges in the replacement/renewal projects. Copernicos enhanced the bridges model with this circular functionality into the Integrated Bridges and Circularity Model. As such Asset Dynamics enables this integral approach to simulate different scenario’s, compare and analyze the results and create insights which supports the decision making in this important Life Cycle Management issue of Rijkswaterstaat. This Asset Dynamics approach combines different objectives (economics: replace/renew bridges and environmental: circularity) and enables optimization between them.

The model is in development (work in progress) but first findings can be shared. We use an action research approach: develop a generic model for bridges in their context with experts, share it in specific projects and learn from those cases. The model is already recognized by the organization as a platform to structure knowledge about bridges, circularity and their mechanisms.

This workshop will start with a short introduction of the simulation models after which we will interactively build a case study with the participants (co-creation)!

Workshop (Monday, 16:30 – 18:00)

Put your (newly acquired) life cycle management skills and knowledge to the test! In this serious game, your (team’s) task as asset manager is to ensure traffic flow, safety with the least amount of budget. You will have many inspection, monitoring and maintenance options at your disposal, although some will cost more than you would like to. Deal with the (shortage) of information, uncertainty, risks, time constraints, external events, etc. and obtain the high score!
