Pipejacking, a trenchless construction technique for installing underground pipelines, helps minimize surface impacts in urban areas, especially in urban areas. However, this method faces many geotechnical challenges such as ground settlement and pipeline instability. This study applies Fuzzy Failure Mode and Effects Analysis (Fuzzy-FMEA) to improve risk management in underground jacking projects, focusing on the Yen Xa Drainage System Project in Hanoi, Vietnam. The results show that integrating Fuzzy-FMEA into a geotechnical management framework is an important development, providing practical insights for urban jacking projects, improving construction safety and efficiency.
