A decision tool for accelerated bridge construction

Abstract

Accelerated bridge construction, which includes the application of innovative technologies and management techniques, is considered an important method for construction and rehabilitation of highway bridges. It mitigates the effects of bridge construction on the public and reduces construction costs. In this paper, a tool set based on the analytic hierarchy process is presented to help transportation decision-makers determine the effectiveness of accelerated bridge construction in comparison with traditional construction for a given project. The authors present a literature review on accelerated bridge construction techniques, decision-making approaches and other related topics, and they develop a comprehensive criteria hierarchy for a bridge construction or rehabilitation that they incorporate into a software tool.
