Denis McMullan, PE

Denis provides leadership in all aspects of structural engineering investigation, design and project management. The more complex the structural problem, the more he enjoys finding a simple and effective innovative solution. In the past thirty years since opening McMullan & Associates, he has always focused on client service and mentoring young engineers. His goal is to build lasting relationships within and outside of the firm. His knowledge spans from all types of historic construction to the latest building technologies. His newest buildings include multistory hospitals and academic buildings. It is also rare to find a National Historic Landmark in Washington, DC that Denis has not touched. His relationships with the Smithsonian Institution, General Services Administration and the Architect of the Capitol span decades. He has also developed a passion for restoring historic canals and aqueducts for the National Park Service (NPS). His worldwide research and expertise have resulted in the successful restoration of the Monocacy and Catoctin aqueducts for NPS and several published articles.

Reflecting on his years of experience and his many projects Denis says, “There is one common thread – the collaboration and values I share with owners, architects and other engineers. We all strive to improve our built environment and leave behind a structure that we have been honored and proud to have worked on, if only for a brief moment in time.”

Mr. McMullan has presented his work on masonry arches and canal structures to numerous organizations and societies, including the Transport Research Board, the Institute for the History of Technology and Industrial Archeology, the Society of Industrial Archeology (SIA), the New Jersey Canal Society and the World Canal Conference.
