Evaluation of bridge infrastructure conditions in Surakarta city using the bridge management system (BMS).

Bridges as a transportation infrastructure require good management for their service functions. Bridges are subject to deterioration and need maintenance strategies to prevent their failing services. The research was conducted in the Surakarta City. The city has a 10% annual growth in transportation modes and 129 bridges which must be periodically inspected/evaluated. This study uses the Bridge Management System (BMS) as a basis for detailed bridge inspection. The evaluation is carried out by dividing a bridge into five levels of elements hierarchy. The assessment criteria are measured cumulatively from the structure (S), volume (K), damage (R), function (F), and effect (P) values by weighting of 1 or 0. Observations and assessments are carried out at the 4 and 5 levels of elements, where the rest are carried out in a superposition of the elements hierarchically. The results of the 129 bridges in Surakarta City investigated with the following criteria: bridges with damaged components or no longer functioning (replacement of components/new bridges) of 1.55%; bridges with critical conditions (rehabilitation) of 8.53%; bridges with damage requiring immediate attention (repair) 34.11%; bridges with damage requiring future monitoring of 30.23%; bridges with minor damage of 11.63% and bridges with no damage of 13.95% respectively.
