John is an Associate with WDP & Associates and works in WDP's Manassas office.

John's expertise in non-destructive evaluation and the condition assessment and repair of concrete structures has allowed him to lead projects involving tunnels, bridges, power plants, high rise structures, and historic buildings.  John has been with WDP for over 20 years and is active with the International Concrete Repair Institute, serving on Committee 210 - Evaluations and formerly served on Committee 150 - Notes on ACI 562 Code Requirements.

“Working at WDP has afforded me wonderful project opportunities - from concrete flood channels in California, to cable-stay bridges in Texas, to highway box beams in Florida, to tunnels beneath our Nation’s capital, and all types of buildings and structures in between.  Each project is unique and poses its own challenges and learning experiences.   Working at WDP means that you have the opportunity to experience the entire repair process:  from fielding the initial phone call, to executing the field survey and sampling process, interpreting the data to determine the cause and appropriate repair, and continuing to see it through to the completion of repairs.  The variety of working environments, locations, structures, and conditions is what makes this job so interesting.”  

Technical Papers & Publications & Speaking Engagements
John co-authored a technical article on “The Application and Advantages of Surface Penetrating Radar in Subgrade Void Detection Beneath Slabs-On-Grade” for Forensics Engineering.  He has given many presentations related to condition assessment and nondestructive testing of concrete and masonry structures.
