Abstract
The 8-inch gas pipeline bridge rehabilitation project in the Mundu-Sunyaragi segment is part of PT Pertamina Gas^s strategic efforts to ensure the reliability and safety of natural gas distribution in densely populated areas. This internship aimed to examine the material specifications and structural designs used in the project, particularly at three bridge locations: Signarela, Karangsambung, and Kedaton. The assessment was carried out through a technical literature review, analysis of the Work Plan and Requirements (RKS) documents, and observation of the procurement process within the Supply Chain Management (SCM) Division. The evaluation showed that the selection of structural steel materials, such as IWF and UNP profiles, was appropriately aligned with technical requirements and field conditions, including mechanical loads and environmental risks. Furthermore, the implemented structural designs considered functional lifespan, cost efficiency, and long-term safety. This internship also provided practical experience in understanding the integration between technical and managerial aspects in national energy infrastructure projects.
