Q&A Session - pdf
News - April 20, 2023 - pdf of presentationDescription: The Rhode Island Department of Transportation is undertaking a major infrastructure rebuilding program titled RhodeWorks. Part of this program involves the replacement of numerous bridges, including the Glenbridge Avenue Bridge. While ABC is a significant part of this rebuilding program, the Glenbridge Avenue Bridge was initially designed and bid with conventional construction details. During preliminary construction, the design was changed to ABC using the lateral slide method. The final design incorporated a hybrid slide system that combined slide rails at the abutments and self-propelled modular transporters (SPMTs) at the pier to move the two-span continuous girder bridge in October 2022. Multiple precast concrete elements were also used to expedite the construction of the abutments. The presentation covers the reasons for conversion to ABC, the design changes required, and the construction of this successful project. Details and lessons learned are included.

Integrated Flood and Socio-Environmental Risk Analysis for Prioritizing ABC Activities - pdf of presentation
Q&A Session - pdf (to be posted soon!)Description: The need to accelerated bridge construction (ABC) activities due to flooding has complex interdependencies with many physical, social, and environmental factors in urban areas. Flood-related factors can also contribute to bridge scour, the biggest cause of bridge failure in the United States. This Seminar presents a GIS-based, multi-criteria decision analysis framework to assess the vulnerability of urban areas against flooding and socio-environmental factors and risk of bridges considering structural and traffic conditions. The final product is a risk map that shows an overall risk factor for each bridge. Application of the framework will be demonstrated for existing bridges in Miami-Dade County, Florida. The proposed framework is systematic, structured, and flexible, making it adjustable to be implemented in different geographic locations. Hence, it can be used by state DOTs as a practical, risk-based decision support tool for prioritizing bridge rehabilitation activities based upon technical, social equity, and environmental justice criteria in the presence of limited budgets.
