Matthew B. Gries

Associate Principal and Unit Manager


Matthew Gries has broad-based experience in condition assessments, structural evaluation, and repair design for buildings, bridges, towers, and utility structures. He has performed nonlinear finite element analysis of concrete structures and has experience with nondestructive testing techniques.

Prior to joining WJE, Mr. Gries evaluated the feasibility of new techniques for improved real-time evaluation of reinforced concrete bridges while a graduate assistant at the University of Illinois at Urbana-Champaign.
