“…The Information System for Bridge Networks Condition Monitoring under GIS Environment has been developed for Department of Science and Technology by CSIR-CRRI. The conceptual departure from the standard bridge management systems may be made using a novel stochastic process built out of the gamma process [5]. The statistical model can then be designed for the estimation of infrastructure lifetime, based on the analysis of more than 15 years of bridge inspection data already available and under study from these bridges.…”

The emphasis for the highway industry in the country is now centered on maintenance, rehabilitation, and conserving the existing road network spread in the form of Expressways, National Highways, State Highways, etc. With the enormous growth in the volume of National Highways across the length and width of the country and more and more State Highways are adding up in the stream of National Highways, the Ministry of Road Transport and Highways and other bridge owner agencies now estimates that more than 80,000 bridges are inadequate to handle the growing demand of traffic, consequently, the higher axle loads both prevalent and nonpartisan. Many of these are due to insufficient strength assessments that often lead to a posted or closed structure. In evaluating existing bridges, the Engineer must consider options including posting, permit regulation, closing, rehabilitation, and replacement. Fortunately, the circumstances of the evaluation, such as past performance experience, shorter expected remaining bridge life, and the opportunity to perform further in-depth study on an existing structure, all provide greater flexibility for evaluations. In order to address effectively, there is a need for a comprehensive framework that covers all bridge conditions, yet is flexible enough for the evaluation agency to consider its own needs and willingness to invest resources, when necessary, in the evaluation investigations. Like many other developing nations, in India too, there is a need for establishing an infrastructure information system for the bridges complemented with bridge management programs. Such infrastructure will provide for a long range bridge evaluation process that considers bridge condition, site traffic, maintenance and inspection cost in a scientific manner.The scientific monitoring has emerged as a powerful tool to assess the condition of structures both in short and long term basis to assist bridge management planners for implementing any bridge management programmes. The CSIR-Central Road Research Institute has accomplished monitoring of many bridges in India in different parts of the country. The paper highlights the salient features of scientific monitoring carried out, the interpretation of results helpful in assessing the condition of the structure and usefulness of such monitoring practices in bridge management programmes.
