Research AdministrationUS Transportation CollectionThe Michigan Department of Transportation (MDOT) uses Accelerated bridge construction(ABC) to reduce delays and minimize construction impacts. MDOT contracted and completedseveral bridges using prefabricated bridge elements and systems (PBES). In 2014, two slide-inbridge construction (SIBC) projects were contracted and completed. These two projectsincluded three bridge replacements. Currently, self-propelled modular transporter (SPMT)moves are being planned for three bridge replacement projects. This study goals are to advancethe implementations by expanding scoping guidelines to include all ABC alternatives,standardize the bridge slides operations, and develop guidelines for foundation constructionwhile 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) reviewingand evaluating substructure construction and upgrades, along with constructability of deepfoundations while an existing bridge is in service, (d) developing specific cost methodologies forSIBC, SPMT moves, and foundation construction, and (e) developing recommendations forupdating the multi-criteria decision-making process and the associated software platform byincorporating the updated framework and the cost-benefit analysis models, foundationconstruction while an existing bridge is in service, and improving SIBC implementations
