Abstrait:

After the collapse of Majherhat Bridge on September 4, 2018 at Kolkata (India), an expert committee was appointed by the state government to ‘examine’ all the old flyovers in the city. A large number of such flyovers identified by this committee, which needed urgent repairs. Two of these flyovers were investigated by the authors as a part of consultancy services provided to the owner client. Both these grade separators were in distress and needed urgent attention. But carrying out condition assessment on these bridges and carrying out any repair posed a big challenge to the Consultants and Clients due to number of factors, including lack of records of the bridges, volume of traffic and critical location of these infrastructures. This paper highlights the broad details of advance assessment techniques adopted for structural condition of these flyovers. The details of proposed repair and rehabilitation techniques adopted are also discussed.
