The tunnel measured approximately 1.8m by 1.8m with a 4m deep, parallel trench system that contained a clay water pipe as part of the aqueduct system. The tunnel took approximately 10 years to construct and was in use for approximately 1100 years. This presentation summarizes the instrumentation, challenges, and techniques that were utilized in order to achieve such an engineering feat. Also included is the historical background, an assessment of the main geological features associated with the tunnel construction, the various tunnel design types, and the relevant tunnel construction techniques that were utilized in order for the tunnels to meet within the intended tunnel alignment (within 1.8% accuracy). Applicable lessons learned utilizing ancient techniques (which are also utilized and are still very relevant today) will be summarized as well as the presenter’s own on-site assessment of the tunnel in its current state. These findings can serve to aid (and inspire) current tunnel engineers and practitioners in the way that they approach their unique tunnel and excavation project requirements. To this day, the acknowledgment and relevance of such an achievement are honored: The current tunnel is designated as a UNESCO Heritage site and also has been acknowledged by the American Society of Civil Engineering (ASCE) as an international heritage site. Speaker Bio: Dr. Nicholas Vlachopoulos is an Associate Professor of Civil Engineering at the Royal Military College of Canada, Cross-Appointed at Queen’s University, and is a Director at the Queen’s-RMC GeoEngineeirng Center. He is the Founder and Director of the RMC Green Team that addresses Infrastructure and Environmental Engineering issues within the Canadian Department of National Defence. His research interests include topics in Geotechnical, Geomechanical, and Sustainable Infrastructure Engineering. Also a member of the Hellenic Society of Soil Mechanics and Geotechnical Engineering, Dr.Vlachopoulos has been collaborating with Greek Universities, Institutions, and Academies spanning two decades and has visited well over 50 construction sites throughout Greece. He is a professional engineer (in Canada and in Greece) with over 25 years of experience in geotechnical/geological, geo-environmental engineering, and project management on major construction and research projects. He has worked at well over 100 locations nationally and internationally. Dr. Vlachopoulos was recently awarded the Thomas Roy Award by the Canadian Geotechnical Society (CGS) for “outstanding contribution to Engineering Geology in Canada”; This is the Premier Engineering Geology Award in Canada.
