Purpose and goal
The overall aim of the project was to further develop and demonstrate a theoretical decision support model developed in a previous BIG BRO project. With three demonstration projects an edge beam replacement of a concrete bridge, a service life prediction of a steel bridge, and for condition assessment of bridges in the forest industry the model is shown to be useful as support for decisions on maintenance actions. The objectives comprising reviewing of bases for decision and the needs of the problem owners have been met with the demonstration projects.
Expected results and effects
The results consist of an summary report describing the demonstration projects where the conditions, the problem owners’ needs and the contribution of the decision model are described. The subprojects have resulted in separate publications in scientific and popular scientific journals. The implementation of the model shows under which conditions more investigations and information gathering is motivated from a risk-based perspective. The demonstration projects show under which conditions this type of decision support can be of use for the decision agents.
Planned approach and implementation
The work began with identification of case studies and user needs, where the different project participants had different areas of responsibility for the various sub-areas of the project. In parallel, the methodology from the previous BIG BRO project was developed to include time-dependent effects and successive assessment of conditions with different methods. The methodology was also adapted to be used in a tool. The case studies were conducted during the second half of the project period to both further develop the methodology and to demonstrate its usefulness.
