Abstract:This report summarizes the research on enhancing the current inspection protocols for MassDOT using 3D scanning technologies. The first part of the report presents a thorough review of the current methods using 3D scanning techniques for bridge inspection. The report also includes laboratory and field scans on corroded beam ends. The research team used different scanning techniques, scanning technologies, and post-processing techniques to find the method that would yield the most accurate result and be the most implementable by the DOT. Part of the presented research was to develop and validate a semiautomated point cloud data/scanning extraction method. Finally, the research team developed a method for 3D scanning to be used in bridge inspection. The main goal of the project is presented at the end of the report and consists of a comprehensive and implementable protocol for 3D-scanning-enriched bridge inspection.
