Implementation of gINT Software at the Virginia Department of Transportation

About the report:

A set of software tools was developed to enable staff of the Virginia Department of Transportation (VDOT) and consultants to streamline processing of subsurface exploration data. Built around the gINT program (geotechnical database and graphics package), these tools allow generation of various geotechnical outputs with a high degree of uniformity. Capabilities include data export to GEOPAK and MicroStation, including automated post-processing, resulting in final drawings conforming to VDOT office practice. In this project, various macros and configuration files were assembled into a single installation file, allowing users to configure their workstation quickly for VDOT projects. The system has already been implemented at VDOT. The install program can be downloaded from the website of VDOT's Materials Division at http://www.virginiadot.org/business/materials-download-docs.asp. A detailed instruction manual is also posted, providing step-by-step directions. The use of this software significantly reduces borehole log preparation time and ensures consistency of output, the latter resulting in a higher quality end product. It is estimated that a VDOT geologist saves approximately 2 full days of work per typical bridge project when using this software, which translates into an approximate cost savings of $600 per bridge. Truly significant savings can be realized over a longer period of time. In the past, some VDOT borehole logs generated manually on paper were not readily accessible after project completion. As a consequence, when new projects were proposed in the vicinity of existing roads and structures, the subsurface information was lacking, necessitating additional exploration, often at great expense. For example, it is estimated that many over water drilling projects can cost approximately $10,000 per day. The software developed through this project will also allow an improved archiving process, thus providing better information regarding local subsurface conditions. It will also help determine if additional boreholes are necessary. Finally, it will allow sharing of subsurface data with consultants and contractors.
