I have been fortunate to have worked on technically challenging problems and protecting people from blast and seismic hazards.

Darell Lawver is an associate principal in the Applied Science Practice. Over the course of his 30-year career, he has provided blast-resistant structural design consulting, published technical papers and taught courses at the United States Air Force Academy.

Since 2001, Darell has worked with the New Mexico Institute of Mining and Technology’s Energetic Materials Research and Testing Center to support full-scale blast tests and develop simplified tools for structural engineers to use in blast-resistant design of steel and concrete structures. His support for this project includes using NLFLEX, the firm’s proprietary finite element software, to perform pretest predictions on elements subjected to blast loading.

Government Work
Darell works regularly with multiple government agencies, including the U.S. Department of Defense, Department of Energy and Department of State, to develop guidelines for blast resistant design. He has led more than 120 projects for these agencies over the past 14 years involving antiterrorism/force protection, explosive safety and design for airport facilities, border patrol and other government buildings. Darell is experienced in both single degree of freedom (SDOF) methods and high fidelity physics-based approaches for evaluating the blast resistance of structures.

Outside of Work
Darell enjoys spending time with Diane, his wife of 35 years, and his two grown sons, Daniel and David. Darell and Diane have a ranch in Lake County, California, where they like to entertain their large extended family. He also enjoys hiking and fishing, and attending San Francisco Giants games.
