With bridges’ aging progresses, inspection and repairing of the bridges have become important tasks to maintain normal functions of the bridges. Currently, the methodology of bridge inspection and evaluation used in Taiwan is called DER&U. However, the DER&U inspection may result in various ratings due to various levels of knowledge, training, and experience of the inspectors. This research developed an Automated Visual-Aid System (AVAS) running on tablet personal computers for facilitating correctness and easiness of the bridge inspection. Before going out to a bridge site, an inspector can download, from T-BMS’ bridge inventory to AVAS, the basic data and historical inspection records of the bridge that is intended for inspection. AVAS provides photos and exhibits of deteriorations of concrete bridges that help an inspector to make proper DER&U evaluations. The inspection results can also be automatically uploaded to the T-BMS database by connecting the tablet PC to any PC connected to Internet. AVAS was field tested and proven to be an effective tool for facilitating the inspection processes. It is expected that AVAS be widely used by the bridge management agencies in Taiwan in the near future.
