Abstract:This research advanced Geotechnical Asset Management (GAM) within DOTD. It describes the logic and software utilized to develop the DOTD retaining wall inventory and outlines a GAM path forward for the Department. The developed GAM GIS database provides geospatial locations, digital storage, digital rating applications, and visual interfaces for retaining walls including historical information. Inventory efforts utilized efficient and effective tools of aerial photography, mapping, and GIS software, web applications, and mobile applications. DOTD can replicate these efforts for other asset types. Researchers developed desk and mobile applications for efficient collection of condition and consequence assessment data into the GIS Database. Districts with their local knowledge should use these tools as part of the rating process. Full GAM development and implementation will provide the department a logical method to manage risk, address problematic locations, and effect a rationale to implement appropriate repairs in a timely manner.
