The Finnish Bridge Management System

A computer-based bridge management system has been designed by the Finnish National Road Administration to assist in high-level bridge policy, long-term planning and programming of investments on the network level, and to help bridge engineers when preparing annual work programmes to reach targeted condition levels. The system applies probabilistic deterioration models to find a condition distribution of the bridges that minimises maintenance and rehabilitation costs for the existing bridge stock, and establishes deterministic repair and reconstruction indexes to organise individual bridges for annual programming.
