Abstract— With a focus on their use in bridge building, the study examines the procedures, methods, and factors that go into erecting precast girders. Large-scale infrastructure projects require precast girders because of their effectiveness and quality, which guarantee less time spent on building sites and less labor. The paper covers several precast girder types, including segmental, box, U, and I girders, and how project needs determine which type is best for a given project. It compares the applicability, benefits, and drawbacks of several erection techniques, such as span-by-span, full-span, and gradual launching. Frameworks such as HIRARC are used to examine the risks related to the erection process, including site logistics, equipment management, and safety precautions. Case studies shed light on difficulties encountered during girder building and give guidance for improving quality and safety. Recommendations for improving construction methods and guaranteeing structural integrity in precast girder constructions are included in the paper's conclusion.
