Cesare Sangiorgi is Associate Professor at University of Bologna. The use of recycled materials and low impact solutions are of primary importance. He is a coordinator of SAFERUP! an H2020 MSCA-ITN project based on Sustainable, Accessible, Safe, Resilient and Smart Urban Pavements
Track 1- Presentation Title: Sustainable, Accessible, Safe, Resilient and Smart Urban Pavements
Abstract: Urban areas have become a jigsaw of living spaces delineated by roads, special lanes, bike lanes, footpaths, squares and the numerous walkable surfaces that permit people’s daily mobility. There are multiple paved areas, the characteristics of which vary according to their potential uses, in the spaces between the buildings where people live, work, study and relax. Urban pavements cover about 40% of urban areas and are the largest and most expensive public property on which people travel every day and they must accommodate all users in the most efficient, safe and enjoyable possible way in modern Smart cities. In a 2020 society that will have gone through an intense economic and cultural crisis and will aspire to more livable cities, a novel approach on how urban pavements are perceived, designed, built, maintained and managed is urgently needed. Safety, sustainability, resilience, accessibility, smart features and aesthetics are the key characteristics that modern countries should invest in for their pavements.

Track 1- Presentation Title: Self-Powered Self-Sensing Automated Civil Infrastructure
Paramount to the concept of a ‘smart’ city is the concept of smart civil infrastructure that can self-monitor to predict any impending failures and in the case of extreme events (e.g. earthquakes, hurricanes, fires) identify sections that would require immediate repair. The monitored civil infrastructure constitutes a network of interdependent systems and utilities including highways, bridges, rail systems, pipeline systems, and buildings, that are necessary for supporting social and economic activities. A major step toward achieving effective structural health and usage monitoring is to enable autonomous sensing, reliable events identification and classification, and self-adaptive capabilities in structural components. This introduces novel design methodologies and forces a rethinking of the definition of multifunctional structures beyond the classical concept based only on load bearing elements. This talk presents an overview of on-going work, funded by the US Department of Transportation, the Federal Highway Administration, and the National Science Foundation, aimed at the development of novel multi-metric self-powered sensing systems that can be applied toward the long-term monitoring of infrastructure components. The novel sensing paradigm is based on the integration of amplified piezoelectric transduction and arrays of ultra-low power analog computational circuits. The miniaturized battery-less wireless sensors are capable of detecting and recording a compressed version of the strain, acceleration, and spectral response history of the monitored structure. Advanced damage detection and quantification algorithms are also discussed based on artificial intelligence methods and big data analytics.

He is a former Vice President of KICT and former Vice President of Korean Society of Civil Engineers (KSCE). He is the Chairman of Korean Peninsular Infrastructure Special Committee and is a Vice President of Korean Institute of Bridge and Structural Engineers. His current research project is a “Development of SUPER Concrete with compressive strength of 80~180 MPa and its applications” for the Ministry of Land, Infrastructure and Transport of Korea.
Track 1 – Presentation Title: SUPER Concrete Technology Opening a New Way of Smart City Infrastructures
For smart and comfortable cities, one of the most important factors is the aesthetics of urban infrastructures with a slimmer and longer-span to maximize space more effectively while minimizing a lifetime maintenance cost and maximizing a service life,.The SUPER Concrete technology is for making it possible, which can overcome the inconvenience of maintenance and aesthetic limitations of steel and concrete. This innovative technology can enhance the beauty, durability and space utilization of the urban infrastructures for smart cities. A new world of infrastructures for smart cities is envisioned by showcasing the applications of SUPER Concrete materials.
Mike LaViolette is a Professional Associate and the National Bridges & Structures Practice Leader with HDR. He has over 27 years of experience in complex bridge design and construction engineering services for US and international projects. His recent and ongoing projects include the Governor Cuomo (Tappan Zee) Bridge in New York, the Pennsylvania Rapid Bridge Replacement Program, the Obhur Creek Bridge in Jeddah, Saudi Arabia and the Mobile River Bridge in Alabama.
Track 1 – Presentation Title: Governor Cuomo (Tappan Zee) Bridge – Innovations and Smart Technologies
Abstract: The recently completed Governor Cuomo (Tappan Zee) Bridge is one of the largest design/build infrastructure projects in the US with a construction cost of approximately $3.9B. This pair of 5 km-long bridges over the Hudson River, including two 366 m-long cable-stayed spans, makes extensive use precast and preassembled bridge components designed to greatly reduce construction time and risk. Furthermore, the project includes a fully electronic toll collection system and an extensive structural health monitoring system. The presentation will focus on the design and construction of the bridge including provisions to satisfy a 100-year service life and the incorporation of smart technologies.
