FDH Infrastructure Services was established in 1994 by two engineering professors and a graduate student from North Carolina State University. The first research question the company investigated was for the North Carolina Department of Transportation. How do you determine the length and integrity of thousands of aging in-situ bridge piles for which no as-built (or limited) information exists? FDH developed a proprietary nondestructive test method, using dispersive wave propagation, to address this challenge. Three patents later, FDH continues to develop and deploy innovative technologies to assess the health of critical infrastructure.Learn More

FDH Infrastructure Services is a proud supporter and member organization of the 100% Tie-Off 24/7 Awareness Campaign. This campaign is an industry-wide safety initiative to raise awareness of the 100% tie-off fall protection requirement and drive home the message that there should be a zero-tolerance policy regarding this law. Many of the accidents that compromise safety in the wireless industry involve situations where the tower technician was not properly tied-off to the structure.Learn More
