| 摘要： | The Michigan Department of Transportation (MDOT) uses Accelerated bridge construction (ABC) to reduce delays and minimize construction impacts. MDOT contracted and completed several bridges using prefabricated bridge elements and systems (PBES). In 2014, two slide-in bridge construction (SIBC) projects were contracted and completed. These two projects included three bridge replacements. Currently, self-propelled modular transporter (SPMT) moves are being planned for three bridge replacement projects. This study goals are to advance the implementations by expanding scoping guidelines to include all ABC alternatives, standardize the bridge slides operations, and develop guidelines for foundation construction while an existing bridge is in service. The tasks completed during this project include (a) reviewing the ABC activities nationally and monitor ongoing ABC projects in Michigan, (b) defining scoping parameters for the implementation of SIBC and SPMT moves, (c) reviewing and evaluating substructure construction and upgrades, along with constructability of deep foundations while an existing bridge is in service, (d) developing specific cost methodologies for SIBC, SPMT moves, and foundation construction, and (e) developing recommendations for updating the multi-criteria decision-making process and the associated software platform by incorporating the updated framework and the cost-benefit analysis models, foundation construction while an existing bridge is in service, and improving SIBC implementations. |
