The Federal Ministry of Transport, Building and Housing is aiming for a comprehensive Management System taking into account state-specific and federal requirements as well as existing regulations in the frame of maintenance planning. The system is subdivided into three processes, each comprising special tools for valuation, analysing and planning. Some of the sub-modules have already been realised, eg the database at state level, the inspection procedure in combination with the procedures of damage and condition assessment and the estimation of future maintenance costs at federal level. Other sub-modules are currently being prepared, eg tools for evaluation and selection of measures. However, a large portion of the essential issues are still in the planning phase, eg program creation by taking restrictions into account. The realisation of the complete Management System will be finished by the year 2005.
The first stage of the work has been to collate information on bridge assessment from the participating countries. In the later stages, the aim is to provide guidelines that reflect the current best practices, a methodology that will allow for future development and sufficient flexibility to accommodate variations in national priorities as the process of harmonisation is pursued. The following tasks fall within the scope of the project: (1) a review of current procedures and standards used for bridge assessment in Europe; (2) the development of models for taking into account the bridge specific traffic conditions and material properties; (3) the use of reliability methods based on a probabilistic approach for bridge assessment including the use of measurements for updating the reliability of structural elements; and (4) the provision of recommendations for methods and procedures that can be adopted for the assessment module of the management framework highlighting where further development will be beneficial.
