Brodie Claybaugh, PE
Senior Structural Engineer
Brodie has 18 years of experience in designing bridges and has performed many bridge jacking and erection procedures throughout his career. He also has experience with steel building erection and critical lift plans. In addition, Brodie spent part of his career working as an internal engineer for a steel erector, giving him unique practical experience.
Peter Quinn, PE
Senior Structural Engineer
Pete is a senior structural engineer with 15 years of experience in bridge design and has performed both construction engineering and up-front bridge design. In addition, he has significant experience in contractor support services, including bridge design support and excavation support design. He also worked on the erection of engineering support for the Hulton Bridge over the Allegheny River, in which the main span was strand jacked into position. Pete is located in the Philadelphia area.
