Raleigh, NC (PRWEB) May 24, 2014 -- The U.S. Department of Transportation has awarded FDH Engineering, Inc. a Small Business Innovation Research (SBIR) grant to develop a new method to inspect and evaluate prestressed concrete. Prestressed concrete comprises 25 percent of the nation’s more than 600,000 bridges.

While many inspection technologies are available to find corrosion in steel tendons of prestressed concrete, no single technology has shown consistent results over the wide range of prestressed structures and inspection settings that are required from the bridge infrastructure market.

Prestressed concrete comprises 25 percent of the nation's more than 600,000 bridges.

However, a new nondestructive evaluation (NDE) method – Nonlinear Impact Resonance Spectroscopy (NIRS) – shows promise in identifying corrosion of embedded steel. FDH has proposed combining the NIRS method with the results from the best proven NDE techniques using a data fusion approach to obtain more consistent and useful results than any of the individual tests for inspecting and evaluating prestressed concrete.

The grant award, totaling $150,000, constitutes the first phase of a possible two-phase research effort. The methods developed in Phase I will be encapsulated into a single portable inspection device, which will be developed into a prototype in Phase II.

FDH was the only Phase I awardee for this grant. Upon successful completion of the Phase I work, FDH will be eligible to submit for a Phase II grant of up to $1 million.

FDH’s research team is led by Dr. Robert Lindyberg, PE, vice president, and includes Dr. Mark Cesare, senior research scientist; Corbin Hardy, PE, director; and Jeff Cohen, signal analyst.

The team also includes participation from North Carolina State University. FDH will work with Dr. Mohammad Pour-Ghaz, an assistant professor in the department of civil, construction, and environmental engineering, to incorporate his research into nonlinear ultrasonic inspection.

The USDOT SBIR Program awards grants to small businesses (<500 employees) to pursue research and develop innovative solutions to the nation’s transportation challenges.
