About
Dave Caughlin is a leading expert in non-destructive testing (NDT) for critical infrastructure, with a specialized focus on the inspection of prestressed concrete cylinder pipe (PCCP). His most notable contribution is the practical application and advancement of Remote Field Eddy Current/Transformer Coupling (RFEC/TC) technology, a patented method that precisely detects and quantifies wire breaks in individual pipe sections. Caughlin’s landmark 2007 study, detailing a field evaluation on a 36-inch transmission main for a major Illinois water utility, demonstrated how RFEC/TC can navigate complex pipeline features like reducers—a challenge that had previously limited inspection accuracy. This work, while cited modestly (2 times), is foundational for engineers seeking to adapt robotic NDT tools to real-world pipeline geometries. By bridging laboratory theory with field deployment, Caughlin has helped utilities proactively manage aging water infrastructure, preventing catastrophic failures. His research remains a key reference for practitioners integrating electromagnetic inspection into asset management programs, underscoring his role in making PCCP integrity assessment more reliable and actionable.
