Bridge Retrofit or Replacement Decisions: Tools to Assess Sustainability and Aid Decision-making

Several sustainability rating, scorecard, and quantitative and/or qualitative performance metrics tools exist to assist in the assessment of sustainability of bridge projects, e.g. the Sustainable Transportation Analysis and Rating System (STARS) and INVEST. These tools are mostly applied after a project is completed or late in the decision when most of the retrofit details have been decided. What is needed are tools to help in the early stages of decision-making about whether to repair or reconstruct bridges when there are more choices open and hence a greater ability to radically reduce environmental and societal impacts. What is missing is the life cycle inventory data to allow comparison of construction and maintenance techniques for sustainability objectives, such as worker safety and increased ozone emission from slowed and stopped car traffic, in addition to cost. This research will set up the framework for a life cycle inventory database for bridge repair and construction techniques including social and environmental sustainability concerns. Bridge experts and practitioners will be recruited to upload their information about the service life of bridges and sustainability impacts to this database. This research will also modify existing early-state commercial product design decision-making tools to create an applicable tool for bridge retrofit decisions utilizing sustainability information available in the life cycle inventory database.
