Robbins TBM Achieves Major Milestone: 13.2 KM Tunnel for Sunkoshi Marin Diversion Project Completed 7 Months Early

T

he Sunkoshi Marin Diversion Multipurpose Project (SMDMP) has celebrated a significant achievement with the early breakthrough of its 13.2 kilometer tunnel, completed in just 20 months—almost 7 months ahead of the planned schedule. This remarkable success highlights the effective partnership between Robbins, renowned for its tunnel boring machines (TBM), and the prime contractor, China Overseas Engineering Group (COVEC). The expedited completion of the tunnel is crucial for the SMDMP, which aims to optimize water resource management for irrigation and hydropower generation in the region. The efficient excavation process not only showcases advanced mechanized tunneling techniques but also reflects the collaboration’s ability to navigate complex geological conditions. Experts in the field have commended the project for its innovative approach to tunnel excavation, marking it as a benchmark for future infrastructure endeavors in Nepal. As the project moves forward, stakeholders are optimistic about the positive impact it will have on local agriculture and energy supply, ultimately enhancing the quality of life for communities in the area.
