The main aim of this study is to conduct thestructural audit of the Sadhu Vaswani Pul which is a Rail OverBridge, situated in Koregaon Park, Pune and to establish thedisplacement sensors developed in the institution as a reliabletest for structural auditing of the bridge decks. Traditionalmethods of auditing like the Rebound Hammer test and theUltrasonic pulse velocity tests have been considered in this study.Very few methods are available for testing the deck displacementand this problem has been tackled here. The novelty of thisresearch is that the institutionally developed displacementsensors are used for determining the deck displacement of theselected bridge. These sensors have not been used before and noon-site techniques are available to obtain the deck deflectionsunder real-time loading. The displacement test on the decks wasconducted. The critical decks which were determined during theVisual Inspections were tested by the displacement sensors. Atwo-axle truck of 18.5 tonnes was passed over the bridge deckand the displacement readings were recorded at the same time.The displacement reading thus obtained indicated the deflectionof the deck under a uniform rolling load. The displacementsobtained were then validated by the standards given inAASTHO-LFRD. After conducting the above tests, the overallcondition of the bridge was determined and the critical sectionswhich should be repaired were mentioned.
