Dan Eschenasy, PE, F.SEI

Principal Forensic Engineer

Dan Eschenasy is a forensic engineer with over 40 years’ experience in structural engineering. In 2022, he retired from the NYC Buildings Department where he was the Chief Structural Engineer.  In this position and as Chief Structural Engineer at the NYC Department of Design and Construction, Mr. Eschenasy was typically the first engineering responder and investigator to almost all major NYC building incidents, such as collapses of buildings, retaining walls, cranes, or other construction installations.

On 9/11 he was tasked to organize the engineering response to the disaster. He also was a member of the ASCE/FEMA task force that investigated the WTC collapse. Published in various technical magazines, the results of his forensic investigations and related statistics became the basis for changes in the structural and construction chapters of the NYC Building Code.

Mr. Eschenasy’s experience will enhance the structural forensic engineering services that GMS already provides to clients including investigations, structural assessments, litigation support, design of mitigation strategies, and post-disaster response. Dan Eschenasy is currently serving on ASCE 7-28 committees as an Associate Member of the Loads on Temporary Structures and Wind Subcommittees.
