GIS APPLICATIONS IN GEOTECHNICAL ENGINEERING

The New Jersey Department of Transportation (NJDOT) Bureau of Geotechnical Engineering currently maintains a large database of boring location plans and corresponding test boring logs. These plans and logs are in hard copy format and are stored in boxes, file cabinets and plan drawers. Locating specific location plans and logs can be a very time consuming process that also relies on the memory of the personnel that are responsible for maintaining the database. This report presents the results of a successful pilot study to investigate the development of a geographic information system (GIS) to better manage and disseminate soils information as developed from test boring results. The Rutgers Soil Series is used in designing roadways and performing preliminary assessments of soil conditions at a bridge or structure. Since the original soil series maps were developed in the 1950s, the base maps used then are not representative of the transportation system as it is today. As such, it is sometimes very difficult to locate a roadway or bridge project using the soil series maps alone. By placing the scanned soil series maps on the NJDOT base map and digitizing the areas of the soil types, the pilot study presented here has resulted in a GIS system that makes it easier to obtain information regarding soil types at a specific project location.
