Dr. Julie Mark Cohen, PE, SECB, is a consulting structural engineer with thirty-three years of professional experience in private practice on a wide variety of new and existing structures as a consultant for structural engineering firms and attorneys for whom she does expert witness and consulting work. Her practice focuses on forensic investigations of structural and construction failures and includes condition assessment, remediation, repair, and upgrade of existing structures, as well as peer review.

Dr. Cohen's forensic practice includes, but is not limited to the following:

  • Forensic investigations.
  • Discovery document review including construction documents.
  • Development and presentation of educational materials on engineering subjects to attorneys.
  • Research for historical and current technical information/facts, state of knowledge, state of practice, and standard of care for attorneys and forensic engineers.

She has worked with structural/forensic engineering firms in NY, MA, IL, CA, and TX as a consultant and peer reviewer on structural steel and reinforced concrete structures, including:

  • Forensic investigations of buildings, bridges, and specialty structures.
  • Remediation and repair of older buildings and non-code-compliant buildings.
  • Analytical studies of historic bridges and their foundations.
  • Analytical condition assessments of high-rise building, large footprint buildings, and specialty structures.

Selected Projects in Practice:

  • Researcher and structural engineering analysist on the development of economic, wind- and seismic resistant structural framing systems for one- and multi-story warehouses with 300 ft x 700 ft, ~50 ft. bays, 30-35 ft. stories, 250-300 psf. Jan. - May 2018. Cancelled.

  • Consultant to lead forensic/structural engineer. Forensic investigation of rain storm (ponding) collapse of 47,100 sq.ft. out of 656,600 sq.ft. roof of one-story pre-engineered warehouse (with light-gauge steel framed roof) located in central Texas. July 2007 - Feb. 2009.
  • Consultant to Plaintiff's (ConEd's) attorney, Mark L. Antin (Gennet, Kallman, Antin & Robinson), on federal civil case on fire-induced collapse of World Trade Center 7, 09/11/2001. Reviewed 20,000 discovery documents (online library). Emphases on interpretation and use of governing building code; 1970-1985 states of knowledge & practice and standard of care across U.S. Sept. 2006 - June 2011.
  • Independent Affiliated Consultant (as NYS WBE) to WJE Engineers and Architects, PC, New York, NY, for NYS Office of General Services. Marble cladding and Llenroc walls at the Empire State Plaza, Albany, NY. Archival research on decision-making process for stone selection, design, detailing, construction photos, project manager's diaries, construction issues, etc. Jan. 2001 - Jan. 2007.
