Terry M. Sullivan, PE

Terry Sullivan is a Senior Structural Engineer Consultant based in Kentucky with more than 40 years of experience focused on risk management and risk-informed design and construction for dams and levees, flood risk management, and navigation structure projects.

Terry has many years of practical experience in the design, construction, operation, maintenance and risk assessment for levee systems in both rural and urban areas and for inland navigation dams and locks. He has also been a senior advisor on several risk assessments conducted for concrete dams, outlet works, spillways and spillway gates. As the lead on the U.S. Army Corps of Engineers (USACE) Risk Management Center’s Hydraulic Structures Workshop, Terry coordinated the input from a world class team of experts on the design and risk assessment of spillways, outlet conduits, and other hydraulic structures. He has served as senior reviewer on dozens of risk assessments for both levee systems and flood risk reduction dams. Terry has a special interest in the research leading to an historical understanding of 20th century urban civil works construction projects, which is useful for developing detailed risk assessments. He was the first Structural member of the USACE Risk Management Center’s Levee Senior Oversight Group (LSOG). Terry possesses industry leading knowledge of the USACE inventory of floodwalls, particularly I-Walls, as well as road and railroad closures and other gate structures. He made significant contributions to the recent updates to Engineering Manuals EM 1110-2-2902 (Conduits, Pipes, and Culverts associated with Dams and Levee Systems) and EM 1110-2-2502 (Flood Walls and Other Hydraulic Retaining Walls).

During his tenure with the USACE, Terry was the Lead Engineer on the Olmsted Dam construction on the Ohio River, as well as the Lead Structural Engineer for the Olmsted Locks Cofferdam, the Olmsted Locks, and Olmsted Approach Walls. These massive projects included pile driving, drilled shaft foundation construction, both mass and structural concrete, and several types of hydraulic steel gates. He was also the Lead Structural Engineer on the innovative design and construction of the Holes Creek Railroad Bridge near Dayton, Ohio. The railroad owner only allowed the tracks to be shut down for 2 hours, so Terry devised a scheme for fabricating the bridge on falsework adjacent to the existing bridge and rolling the new bridge into place. This was one of the first accelerated bridge construction projects in the U.S. Terry was also the lead structural designer for the Duck Creek Phase 3 floodway culvert near Cincinnati, Ohio. All these projects incorporated new types of construction technologies to allow site work and prefabrication of structural components to be carried on simultaneously, reducing construction durations.

Terry was also part of the joint USACE and industry team on the Lake Borgne Hurricane Surge Barrier in New Orleans. This project closed off the eastern approach of Gulf based hurricane storm surges from entering the Gulf Intracoastal Waterway, and incorporated construction technologies on a massive scale that required site work and prefabrication of structural components to be carried on simultaneously, significantly reducing the construction duration. Significant dam and levee safety risk assessments include the Louisville, Kentucky Levee System SQRA, the Buckhorn Dam Issue Evaluation Study, the Oahe Dam Issue Evaluation Study, the Ouachita River Levee System SQRA and the Waterbury Dam Issue Evaluation Study.

To advance the state of the practice, Terry continues his participation in groups such as the American Society on Dams (USSD), the American Society of Dam Safety Officials (ASDSO) and the International Association for Hydro-Environmental Engineering and Research (IAHR), where he is an active member and has participated and/or presented at their conferences. He has published several papers on geotechnical and structural implementations at dams, levees, and hydraulic structures. Terry has received multiple awards for his significant contributions to Olmsted Locks and Dam, Rough River, Duck Creek, Bluestone Dam, and Holes Creek, among others.
