The Netherlands has an extensive infrastructure. With a value of € 350 billion, this infrastructure is an important asset for our economy, and every year approximately € 6 billion is spent to maintain and preserve it. Good asset management results in lower costs, greater availability and predictable funding needs, and prevents unnecessary hindrance.

TNO works on methods, models and techniques for analysing the three elements (cost, risk and performance) of maintenance scenarios and innovations and obtaining specific, transparent, straightforward and comparative information. This provides decision-makers with insight into the consequences of the choices they make.

Decision-supporting information

Good management and maintenance require information on the cost (including long-term costs) of scenarios and the consequences of the scenarios in terms of performance and risk. TNO develops models that can provide clear, straightforward and transparent information. These include a model for analysing the social costs and benefits of maintenance work ('MKBO' model) and the framework that was developed in the European ASCAM Project (asset service condition assessment methodology) and is being developed further in the European TRIMM project. Models such as these make it possible to calculate maintenance scenarios and hence generate predictions for the costs, risks and performance of the asset.

TNO also provides cost-benefit models for specific innovations, such as the social costs and benefits of using monitoring systems for specialist applications (steel bridges, expansion joints, asphalt, cathodic protection). With these calculations, too, we provide asset managers with the necessary decision-information to make responsible decisions.

Monitoring and Asset Management

Europe's infrastructure is ageing rapidly. As a result, the emphasis is shifting from building new infrastructure to maintaining existing infrastructure. TNO develops techniques, methods and models to... Read more

Extending service life civil structures

Structures are designed to have a long service life. This is usually between 50 and 100 years. Many of the civil structures in the Dutch infrastructure are more than half way through their intended service... Read more

Repairing and protecting asphalt

Damage to road surfaces cannot be avoided. Often, it occurs after only a few years of use. On national trunk roads in the Netherlands, this damage usually takes the form of stone loss from the porous... Read more

Probabilistic method

Probabilistics is a methodology for dealing with uncertainty in calculations. It is a core area of expertise for TNO and we apply it in our research on various safety issues. We use probabilistic methods... Read more
