Before beginning his master’s degree in 2009 and joining GHD in 2011, Fecteau worked as a Civil Engineering Technician in materials quality control for 4 months for Groupe Qualitas Inc. His MSc and ongoing PhD studies, both from Université Laval, led him to specialize in the evaluation of concrete affected by alkali-aggregate reaction (AAR, both alkali-silica reaction and alkali-carbonate reaction) through Federal Highway Administration (FHWA, USA)-sponsored research projects. He was then hired by GHD and acted as a team leader of four professionals and two technicians, Project Manager, and Petrographer, specializing in various concrete and other materials (including rock characterization). In addition, Fecteau was the supervising specialist for all AAR testing for GHD and the lead Petrographer in Quebec. Since April 2019, he has served as a Research Associate at Université Laval, where he supervises and coordinates the work of the Research Chair NRCC – RBQ and Partners “Impact of Pyrrhotite on the Durability of Concrete Structure,” jointly led by Professors Josée Duchesne and Benoit Fournier, both from the Geology and Geological Engineering Department. Fecteau is President of the Board of Directors of the ACI Quebec and Eastern Ontario Chapter; a member of ACI Committee 221, Aggregates for Concrete; Member of the Ordre des ingénieurs du Québec (OIQ), former Vice-President and Director of the Quebec City affiliated sub-chapter of ICRI (Quebec Province chapter), and former invited collaborator to the CSA subcommittee on aggregates for concrete of CSA A23.1-A23.2. 1st Speaker: Eric Samson, Eng, PhD, VP of Engineering, SIMCO Technologies Inc. Dr. Eric Samson is the VP of Engineering at SIMCO Technologies Inc. He specializes in concrete durability and the prediction of the degradation of concrete structures exposed to aggressive environments. He actively worked on the development of STADIUM® software and other engineering tools related to concrete durability. Samson has participated, as principal author or coauthor, in the writing of over 60 scientific papers in the field of service-life prediction of concrete structures. He currently supervises a research team of engineers and scientific researchers dedicated to the development of the STADIUM® software and the extension of its features. He was also involved in several major engineering projects related to concrete durability. Co-Author: Richard Cantin, Concrete Durability Subject Matter Expert and Project Director Richard Cantin is a concrete durability subject-matter expert and Project Director for SIMCO Technologies. He has over 20 years of experience managing large-scale infrastructure projects, conducting inspections, and condition assessments. He specializes in the characterization of damaged concrete infrastructure and 1 Tuesday, July 13, 3:10-4:00 pm Quebec Time / 3:10-4:00 pm Detroit Time Co-Host Organization: ACI Quebec and Eastern Ontario Chapter service-life evaluations. His advanced knowledge of SIMCO’s STADIUM® numerical modeling tool, combined with his extensive knowledge of degradation mechanisms and repair techniques, allow him to identify optimal solutions to extend the useful life of concrete structures while minimizing total intervention costs. Cantin is an active member of ACI and the Association for Materials Protection and Performance (AMPP) technical committees including durability of concrete, service life, evaluation, repair and rehabilitation, and corrosion of metals in concrete. Presentation Title: Optimizing the Value of Field Data for Concrete Structure Durability Analyses Field data are routinely collected on concrete structures to better understand the durability of the material in relation to its environment. Field data are a good indicator of the current state of a structure. In an era of unprecedented expenses to rehabilitate existing structures, they provide relatively low-cost information to assess damage and degradation sustained by concrete, compared to a large-scale coring program. However, they can also prove complex to analyze. The objective of the presentation is to highlight the benefit of combining field data to other information, such as modeling solutions and data collected on a small number of cores. One typical example is the information provided by half-cell potential measurements. Although guidelines are provided in standards to make sense of potential data collected on structures, they can prove challenging to analyze in some cases. The presentation shows how the combination with modeling can help evaluate the extent of corrosion of reinforcing bars better and thus better assess a structure’s current condition. 2nd Speaker: Benoit Fournier, Eng, PhD, Professor, Department of Geology and Engineering Geology, Laval University Dr. Benoit Fournier is a Professor in the Department of Geology
