GET TO KNOW Ahmad N. Elhajj, P.E.

Building upon dual engineering and applied science degrees, completed simultaneously within just four years of undergraduate work, Ahmad Elhajj, PE, continues to demonstrate his commitment to life-long scientific and engineering learning, completing his master’s degree in civil engineering (with focuses on structural, geotechnical, and wind engineering) and charting a new course beyond. Along this journey, his diversified educational background has also included software development capable of empowering cutting-edge computer-aided analysis of complex structural collapse mechanics and design improvements for advancing the resiliency of our built environment. His unique combination of engineering skills, scientific analysis capabilities, data analytics, and results visualizations helps him to communicate highly complex scientific and engineering principles in simple and easy-to-understand verbal terms and visually intuitive demonstratives.

Mr. Elhajj also serves on the Committee on Practices to Reduce Failures within the American Society of Civil Engineers, as well as the Committee on Performance-Based Design of Concrete Buildings for Wind Loads within the American Concrete Institute, giving back to and advancing, the professions of engineering and forensics. At the Miller School of Albemarle in Charlottesville, VA, he taught both physics and engineering classes while developing their pre-engineering educational program. He is currently registered as a Safety Assessment Program Evaluator with the California Governor’s Office of Emergency Services, providing post-disaster relief to impacted communities. His service to others further demonstrates his commitment to his craft.

Licensed in ten jurisdictions, Mr. Elhajj leverages over a decade of broad-based professional experience in the engineering, design, testing, construction, and litigation support technical arenas. His previous work at the Virginia Center for Transportation Innovation and Research involved the study, research, testing, and development of concrete admixtures using non-destructive testing techniques, mix design, and laboratory analysis. His previous work with Hilti touched multi-disciplinary facets of the engineering and construction industries, including structural and civil engineering, custom software development, non-destructive evaluations, construction materials science, and advanced firestopping/fire protection systems.

In his forensic practice, Mr. Elhajj applies meticulous attention to detail, delivering comprehensive scientific analysis and reporting in order to educate lay audiences with answers to their technical questions. He brings the big picture into focus, with the thorough scientific data and analysis needed to qualify its soundness. His capabilities extend well beyond traditional cause and origin determinations to include wraparound services like cost estimating and remediation design, as applied to the constructed built environment as a whole, temporary construction supports and structures, and construction materials. Structures of all types, bridges and buildings, from the ground to the sky, carefully analyzed under the applied sciences governing their physical behavior, this is Mr. Elhajj’s craft — Investigative Sciences, Applied.
