The impact of different maintenance policies on ownerscosts: Case Studies from Croatia and the Netherlands

Optimisation of maintenance planning is an important part of bridge management. The efficiency of condition assessment process is directly influencing the choice of repair and maintenance technique, i.e. measures which have to be undertaken. This paper examines the effect of two opposing maintenance strategies, corrective and preventive maintenance. The condition rating and planned maintenance costs for structural elements of bridges at different ages are compared. In case studies from Croatia and the Netherlands, data from previously performed inspections was compiled in order to correlate age, condition and costs for structural elements. The case studies have been used to assess the impact of different maintenance policies (corrective vs. preventive) on the occurred maintenance costs.
