The Moscow Bridge Management System (MOST) provides oversight for approximately 850 structures, including bridges, overpasses, tunnels, embankments, and pedestrian crossings. MOST contains the software necessary for inspecting structures taking into account their deterioration, for servicing structures, and for planning the optimal strategy for maintenance and repair within budgetary constraints. To describe a structure, MOST employs a specially developed expandable catalog of standard structural elements (SSEs), to which correspond a deterioration model, a set of several condition states, and a set of standard repair procedures. Unlike other bridge management systems (BMSs), MOST develops a bridge's inspection plan and establishes bidirectional correspondence between bridge drawings and the list of SSEs in the database. This is extremely helpful in making adequate repair assignments. Maintenance, repair, and rehabilitation activities and their associated budget are planned and optimized from data obtained during standard inspections. Plans can be drafted for the entire network of bridges, for several selected structures, or even for a particular group of SSEs. Calculations are performed in an interactive mode, which makes it possible for the user to change coefficients and criteria in relation to specific conditions. Through implementation of this BMS, municipal services of the Moscow government have gained the ability to objectively evaluate the condition of city structures and optimize planning for long- and short-term repair activities. |
