I enjoy working with interesting people to solve challenging problems.

Jim Weeks is a principal in Thornton Tomasetti’s Weidlinger Applied Science practice. He has more than 35 years of diverse management and engineering experience. He has served as the lead structural design engineer on a range of projects, including office and residential buildings, industrial and storage facilities, laboratories and testing facilities and pumping stations and control buildings. Jim has particular expertise in the design and analysis of structures subjected to dynamic loads and is experienced in linear and nonlinear finite element analysis.

Design Expertise for Extreme Loading Events
Jim has extensive experience supporting clients in the defense, petrochemical and nuclear fields, providing technical services to identify and mitigate the effects of extreme loading events. He has performed analysis and design for blast and fragment loads, and nuclear-related natural phenomena hazards. Jim is well-versed in U.S. Department of Defense and North Atlantic Treaty Organization explosive safety requirements, as well as U.S. Nuclear Regulatory Commission and U.S. Department of Energy nuclear facility design requirements. Jim is a retired lieutenant colonel in the U.S. Army, with expertise in threat analyses and defense planning.

He currently serves as program manager for a three-company joint venture that for the past six years has been providing multi-discipline design and analysis services to the Los Alamos National Laboratory in New Mexico.

Outside of Work
Jim enjoys spending time with family. He and his wife Lynn have been married for more than 20 years. They have two college-age children: Mike, a senior at Notre Dame, and Kimmy, a junior at UT Austin. Jim’s hobbies include exercising, bird hunting, fly fishing, biking and reading.
