About FDR
FDR Engineers, PLLC is owned and operated by individuals whose primary goal is to adopt and fulfill the vision of each project's owner and architect while maintaining budget and meeting all schedule requirements. We think outside the box, strive for innovative solutions, and pride ourselves on delivering the highest quality structural engineering services and building excellent working relationships with our clients.
Capabilities
FDR Engineers is licensed in 47 states, and every drawing we issue is sealed by a Professional Engineer licensed in the project's own jurisdiction. Our core practice is full structural design — foundations, reinforced concrete, structural steel, wood, and light gauge framing — carried from schematic design through construction administration.
Where we go deeper than most firms is cold-formed steel. We engineer panelized and field-installed exterior wall systems, deliver Revit BIM models and fabrication drawings straight to the framing contractor, and design cold-formed steel roof truss and permanent bracing systems. That work is why framing contractors, panel fabricators and general contractors across the country bring us in on projects their local engineer has never seen the like of.
We also keep a specialty protective design practice, with analysis tools that run from simplified SDOF and linear finite element through advanced non-linear dynamic applied element software — the range required to meet DoD antiterrorism criteria and progressive collapse standards on federal and military work.
Principals
FDR Engineers' principals have a wealth of knowledge and experience in diverse areas of structural engineering for both commercial and residential applications.
Justin Fejfar, P.E.
Mr. Fejfar has more than 25 years of experience in commercial, industrial, and residential building design, dynamic analyses of steel structures for anti-terrorism blast loadings, three-dimensional static analyses, and linear finite element analyses. Mr. Fejfar is a graduate of South Dakota School of Mines and Technology where he earned his M.S. in Civil Engineering and is a Professional Engineer Licensee in more than 20 states. Mr. Fejfar has extensive experience in all types of structures including: reinforced concrete, pre-stressed concrete, structural steel, cold-formed steel, heavy timber, log framing, and reinforced masonry.
Edward di Girolamo, P.E.
Mr. di Girolamo received his B.Sc. in Civil Engineering at SUNY Buffalo, New York. Mr. di Girolamo has more than 35 years of experience in building design, manufacturing, construction, demolition, and structural software development. His broad experience with structures encompasses nuclear plants, navy ships, bridges, & commercial and residential structures. To date, he is a named inventor on over 20 construction product patents. Mr. di Girolamo founded the light steel framing manufacturer, The Steel Network, Inc. (TSN) in 1994 and the structural software firm, Applied Science International, LLC (ASI) in 2004.
Nabil Rahman, Ph.D., P.E.
Dr. Rahman has more than 30 years of experience in building design, development of engineering software, and the special design and analysis of structures against extreme loads (progressive collapse, blast, and impact). Dr. Rahman is a graduate of McMaster University, Canada where he earned his Ph.D. in Civil Engineering. He has expertise in the area of cold-formed steel design utilized in the light steel framing industry and has recently served as the President of the Cold-Formed Steel Engineers Institute (CFSEI). Dr. Rahman is the current chairman of the ASCE-SEI Committee on Cold-Formed Steel.
Heath Hendrick, P.E.
Mr. Hendrick has more than 20 years of experience in the engineering and construction industry. He has an extensive background in both design and construction management and administration. Mr. Hendrick is a graduate of The University of North Carolina at Charlotte, with a project resume spanning all facets of the commercial, government, educational, medical, and residential markets.
Simon Hoppman, P.E.
Mr. Hoppman has more than 10 years of experience in building facade, load bearing, and lateral analysis engineering. Mr. Hoppman has a Bachelors Degree in Civil Engineering from the University of Wisconsin-Platteville and holds Professional Engineering Licenses in multiple states. His experience includes residential and commercial work and he has personally managed a vast spectrum of project types with a wide breadth of building materials.
