FDH has played an important role in developing the technology required to assess the condition of critical structures, monitor their performance, and design the solutions that extend their lifespan. The company’s research and development of nondestructive test (NDT) methods for evaluating the condition of concrete, timber, and steel structures has led to the award of three U.S. patents (with a fourth pending) and multiple proprietary analysis techniques.
FDH’s innovative NDT methods are grounded in a robust R&D program that is client driven and backed by more than 25,000 investigations of civil and industrial infrastructure. The epicenter of the R&D program is the structures laboratory, based in Raleigh, NC. Used for both training and investigation, this 2,500-square-foot indoor/outdoor facility helps the firm’s PhD-level researchers refine and validate existing NDT technologies as well as develop and deploy new NDT methods that solve unique problems in critical infrastructure.
FDH’s extensive field work and R&D efforts have been conducted in cooperation with multiple research facilities, including, but not limited to, North Carolina State University (NCSU), Duke University, Marshall University, the U.S. Army Research Office, and the U.S. Army Corps of Engineers (USACE) Engineer Research and Development Center (ERDC), as well as various state highway agencies (SHA) and transportation departments. These vital research collaborations keep FDH at the forefront of advancements in engineering investigation and NDT methods.
