Description: Accelerated bridge construction (ABC) can significantly reduce construction time and traffic disruption, yet there is a growing concern for elevated costs and project delivery issues that are yet to be thoroughly investigated. Alternative Technical Concepts (ATC) is one method of early contractor involvement to propose modifications to contract requirements that address potential high cost and project delivery issues in ABC projects before the bidding process. This research identified and analyzed factors that impact ATCs for project delivery of ABC projects through the analytic hierarchy process (AHP). Additionally, the study identified case studies of ABC projects that successfully integrated ATCs and exploited its benefits. The qualitative data obtained from case studies and interviews facilitated the development of a streamlined procedure for ATC adoption that facilitates successful acceleration of design, construction process, and procurement of ABC projects.
