A Comprehensive Decision Support Tool for Accelerated Bridge Construction Considering Social Equity

The suitability of using accelerated bridge construction (ABC) techniques in bridge construction projects has potential interdependencies with several social and environmental factors related to communities affected by the bridge project in addition to economic, safety, and technical factors related to the design and construction of bridges. Decision-makers (e.g., Departments of Transportation- DOTs) need to assure that the ABC techniques are thoughtfully viewed since many of the projects have access to limited budgets and time and include construction limitations. State DOTs across the country utilize different decision-making approaches, ranging from complex to simpler processes, for determining the suitability of ABC methods in bridge projects. Connecticut DOT (CTDOT) uses a middle-ground multi-criteria decision-making approach entitled “ABC Decision Matrix” based on a spreadsheet tool to aid decision makers in adopting ABC methods. The CTDOT Decision Matrix is a relatively simple, yet effective, tool that deserves improvements to become more comprehensive, less subjective, and more flexible to be used by other state DOTs.
