Geotechnical investigations are routinely required for planning, design, construction support, and emergency response on all ODOT projects involving structures and roadway construction. This process generates an enormous amount of data of significant value to a broad geotechnical engineering and construction community. A Geotechnical Data Management System (GDMS) is needed to provide a centralized hub of information that will incorporate archived data, geologic hazard inventories, ranking matrices, remediation cost, boring logs, laboratory test results, and technical
