John Fraczek

Senior Principal


John Fraczek rejoined WJE in 2001 and is engaged in the resolution of design- and construction-related structural and materials problems. He has investigated and designed repairs for foundation and seismic issues with large precast, post-tensioned liquid retaining structures and reinforced concrete structures in general. Dr. Fraczek also has expertise in structural steel, structural vibrations, and structural repair and rehabilitation. He originally worked at WJE from 1979 through 1991, and was actively involved in all in-house research on corrosion and concrete durability. He also was involved in a broad variety of consulting activities associated with timber, aluminum, steel, and reinforced concrete structures.

Prior to rejoining WJE, Dr. Fraczek worked as an independent consultant. From 1991 to 1999, he served as the president and CEO of Construction Technology Laboratories, Inc., a 130-person engineering consulting firm in Skokie, Illinois. Dr. Fraczek is an established author and previously served as a principal speaker in a nationwide seminar series on concrete repair and restoration. He has presented numerous lectures on structural failures, repair techniques, materials performance, and nondestructive testing.
