Asset Deterioration: Determining Probabilistic Maintenance Intervals

The municipality of Amsterdam is facing the challenge to deal with uncertainties accompanied with the maintenance planning of maintenance activities on bridges. Long term asset planning (LTAP) has the goal to show the proposed expenditures, capital and operational expenditures (CAPEX and OPEX), for the long term to be able to build up a monetary...

Innovation in routine infra maintenance: Stakeholder inspired service development

This report discusses the process that was used to redesign the service of routine infra maintenance. New governmental demands have led to new contract demands for infrastructure contracts. These new contracts require a new approach to infrastructure maintenance. Contractor bid's are no longer selected on a base of price only, but EMVI ...
