Assessing the remaining lifetime of the Haringvliet sluices: A method for a full system analysis of existing hydraulic structures to quantitatively and qualitatively determine plausible adaptive courses for their remaining lifetime

Many Dutch infrastructure assets were constructed in the first half of the 20th century and by considering an average design life time of roughly 100 years, a lot of these structures will reach the end of their designed life in the upcoming decades. This results in a large replacement and renovation challenge in the nearby future. Assessing the...

The effects of floods on residential property values

Being both a low-lying delta and having one of the most significant mortgage-to-debt-to-GDP ratios in the world, the Dutch economy is vulnerable to damages to real estate due to floods as this could lead to large-scale householder default and ultimately destabilize their economy. Notwithstanding, a generic and widely adopted tool to assess flood...

Assessment of Maintenance Strategies for the Next Generation Meuse Weirs

The Meuse is a river in West-Europe which rises at the Langres Plateau and flows from France through Belgium and the Netherlands. The river has always been an important shipping route, even though its navigability has been problematic in the Netherlands. To solve this problem seven weirs were constructed in the Dutch part of the Meuse. They are...

Assessing the remaining life of the Hollandsche IJssel storm surge barrier

The Hollandsche IJssel storm surge barrier is expected to last another 40 years, but replacement or renovation may be needed sooner than anticipated due to factors such as climate change and societal developments. Yet, there is relatively little known about what factors and how these factors influence the remaining life, and methods that can be...

Utilizing the potential of infrastructure renovation programs: An explorative research on how goals can be controlled and synergies can be utilized in infrastructure renovation programs

In the upcoming years in the Netherlands, the Dutch government will be focusing on renovating infrastructure assets. Moreover, a shift from organizing each project individually to a more program-oriented approach has been observed in renovating infrastructure, whereby synergy a prominent feature is. In addition, it is becoming increasingly...

Assessing circular buildings: A balance between circularity and life cycle costs of a building

Being one of the world’s largest waste generator, the construction industry is responsible for a train of events such as global warming, climate change, and depletion of natural resources. Materials are exhausted globally to a large extent and the waste produced in the process is not treated properly. A “take-make-dispose” or popularly known as...

Towards Risk-based Prioritisation of Primary Navigation Locks: As an improvement to the existing method used for scheduling renovation work

The operation and maintenance of most of the Dutch primary navigation locks are the responsibility of Rijkswaterstaat. The portfolio of Rijkswaterstaat consists of 52 primary navigation locks that are part of the primary flood defence. All these navigation locks are assigned a safety norm together with the adjacent water-retaining bodies. For...

A new criticality analysis approach for infrastructure components: New FMECA approach for Infrastructure asset management

Infrastructures have become important for the holistic growth of any country. With the number of such projects being constantly on the rise each year, its efficient maintenance has become a primary requirement for any asset owner. Among the many techniques available, FMECA is widely used for maintenance planning. In this method, different...

Flexibility and Uncertainty in Infrastructure Investment Valuation: A roadmap for valuing bridge life cycle investments taking flexibility and uncertainty along

Internal and external uncertainties like structural integrity, load, demand, weather conditions and spatial planning have an impact on Infrastructure assets. Incorporating uncertainties and flexibility to decisions by means of more information becoming available, adds value to new investments, life time extended maintenance and replacements. The...
