THE ROLE OF ECONOMIC EVALUATION IN THE BRIDGE MANAGEMENT PROCESS

Bridge maintenance has been a growing concern in many countries around the world, particularly the developed countries. Increasing service demands, both in terms of traffic volume and weight, combined with a growth in cases of early deterioration of structures and added to the large, but insufficient, amounts of money invested in maintenance, repair and rehabilitation, results in a complex picture that highlights the importance of this subject. Bridge Management implies the storage of a large volume of data captured from inspections and the manipulation of this data to assess the conditions of the network and prioritise maintenance activities. The paper describes research work which is trying to justify a structured way to explore this kind of knowledge, recommending the use of an elicitation process in order to produce a method that adequately takes into account the effect of the related and indirect costs of rehabilitation. In this way it is expected that a more reliable and precise economic analysis of the condition of the bridges could be achieved, contributing to a better utilisation of the usually insufficient resources available to the maintenance of the bridge infrastructure.
