Terracon has been providing non-destructive foundation testing on Nevada bridge infrastructure since 2003. During this time, we have provided testing for over 20 projects throughout the state. These projects include the Henderson Spaghetti Bowl Project, the U.S. 395 Widening project, and the I-580 Project. The I-580 project alone required foundation testing on multiple bridges, including the Galena Creek Bridge, the largest concrete cathedral arch bridge in the world. Our non-destructive testing program includes crosshole sonic logging (CSL), pulse echo testing (PIT), and crosshole tomography (CT). Terracon's services are performed under a contract with the Nevada Department of Transportation (NDOT). The project owner is NDOT.
