FINNISH PROJECT LEVEL BRIDGE MANAGEMENT SYSTEM

The Finnish Bridge Management System (BMS) consists of two different parts: the Network Level BMS and the Project Level BMS. The Project Level BMS, which deals primarily with individual bridges, uses the recommendations and goals from the network level to decide on the repair measures in individual repair projects to create repair and reconstruction programmes. The project level system is the key tool for everyday bridge repair planning in the road districts. The system helps the bridge engineer to plan and schedule the repair projects for individual bridges based on the recommendations and the damage data in the database. The system works with repair and reconstruction programmes. In connection to these programmes different alternative studies and profitability calculations can be made. For example, analyses concerning bridge structural parts and bridges remnant life will be available. A ranking system is used when picking out the bridges which need either repair and rehabilitation or reconstruction measures. An index describing the repair needs of individual bridges was taken in use for the purpose of arranging the bridges in an urgency order in the work programme. This repair index is a function of a bridge structural part’s estimated condition, damage class and the repair urgency class. The programme is prepared so that the condition target can be reached by following the given repair recommendations.
