    Timothy Lynch, PE is a NYS licensed Professional Engineer with over 35 years of engineering experience. Up to June of 2022, Mr. Lynch served as the Chief Enforcement Engineer for the New York City Department of Buildings (DOB). Since 2005, Mr Lynch has served with the DOB in a number of titles, working on all types of field and engineering evaluation issues related to the public safety of NYC’s 1.1M existing buildings. As a structural engineer, using all his years of experience, he has coordinated and attended DOB’s engineering responses for partial and full building collapses, and the immediate efforts required to make them safe using shoring campaigns, demolitions or short and long term repairs. Regular responses and management were daily tasks required to make buildings safe for occupants and the public when serious structural stability issues arose from construction accidents and errors, fires, and structural decay from weathering and wear and tear. The work also required responding to, managing and coordinating NYC’s response to major weather events such as hurricanes and large coastal storms. These can impact anywhere up to 100K of NYC’s buildings, in particular, family dwellings located in coastal areas as was the case with Superstorm Sandy. The emergency response work also extended to out of state deployments up and down the Atlantic seaboard, where NYC provided expert engineering help for building evaluations through its mutual aid programs.
