The Geotechnical Engineering Unit of the New Jersey Department of Transportation (NJDOT) maintains a large, statewide, geospatial database of soil boring information. The Geotechnical Data Management System (GDMS) provides you with the ability to search for boring location plans and boring logs using interactive map interface.

We have made multiple improvements to the GDMS application for improved usability and to facilitate the incorporation of new data into the system. Returning users may find some changes in behavior from what you are used to. Please review the help system to see what has changed.

The tools can be found here:

Additionally, you may download the standard submission template (here), and, if you work with NJDOT, you may submit your completed template for inclusion in the soil borings database.
