Kenneth P. Marley

Senior Associate


Since joining WJE in 2011, Kenneth Marley has specialized in structural analysis and repair. He has experience with conventionally reinforced, prestressed, and post-tensioned concrete structures, including parking garages, plazas, and high-rise towers. His bridge engineering projects include built-up steel trusses, precast and prestressed plank bridges, prestressed and post-tensioned girders, cable-stayed bridges, and steel plate and concrete culverts. Mr. Marley performs condition evaluations and failure investigations, including the use of nondestructive test methods. He also performs assessment of tensile membrane structures.

Prior to joining WJE and as a doctoral candidate at the University of Illinois at Urbana-Champaign, Mr. Marley studied the behavior of boundary regions in large-scale cyclically loaded structural walls.
