Jonathan C. McGormley

Senior Principal


Jonathan McGormley joined WJE in 1994 and has been involved with the structural evaluation and repair of commercial and residential properties, bridges, parking structures, and other deteriorated or distressed structures. He is routinely called to assess the condition of structures after fire, storm, and impact damage. Mr. McGormley is experienced in the inspection and evaluation of steel bridge structures with an emphasis on fatigue and fracture problems. He is experienced in visual, magnetic particle, and ultrasonic testing techniques, and has overseen bridge retrofit projects in which WJE personnel were responsible for self-performing the work. Mr. McGormley has conducted numerous instrumentation and field testing projects to better characterize the behavior of structures. He has also performed construction engineering services, design reviews, and building code compliance checks, and is experienced in the finite element modeling of steel, concrete, and aluminum structural members. Mr. McGormley’s analysis experience includes the structural evaluation of tensioned fabric structures for several production companies.
