Evaluation of the Indonesian Standard Guidelines for Long-Span PC Girder Erection

Road infrastructure development in Indonesia has increased the use of long-span prestressed concrete I-section (PCI) girders for bridge structures. However, these girders have instability issues during construction that resulted in multiple failures between 2017 and mid-2018. To address this problem, engineers compiled a standard guideline for erecting long-span PCI girders that includes three recommendations: a lifting point or lifting frame, a dapped-end girder, and artificial stiffeners. In late 2022, despite the initial effectiveness of the guideline, a video revealed that PCI girders were still vulnerable to failure despite strict adherence to the guidelines. A subsequent study reviewed the guidelines and revealed that not all the guidance was effective. The study emphasized the importance of standardized bracing at the supports. Therefore, it is necessary to revise and improve the guidelines to prevent similar failures in the future.
