John Fraczek

Senior Principal


John Fraczek is an expert in the resolution of design-, construction-, and materials-related structural issues. He has investigated issues with mat and deep foundations, mass concrete, and numerous reinforced and prestressed concrete structures. Dr. Fraczek also has expertise in structural steel, structural vibrations, nondestructive testing, and structural repair and rehabilitation.

Dr. Fraczek is an established author who 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, mass concrete, materials performance, and nondestructive testing.

He originally joined WJE in 1979 and was actively involved in in-house research on corrosion and concrete durability during the early years of his career. From 1991 to 1999, he served as the president and CEO of Construction Technology Laboratories, Inc., a 130-person concrete-materials testing and consulting firm in Skokie, Illinois. After working as an independent consultant, Dr. Fraczek rejoined WJE in 2001.
