AB  - This paper examines the practical implementation of lean principles in the contract management and operations of the TU 02 underground metro project in Chennai City, India. The project, a crucial component of Chennai Metro Rail Limited's Phase 2 development spanning 116 km, stands out for its intricate collaboration with multiple contractors. Despite its scale and complexity, CMRL TU 02 project team has embraced lean management principles since its inception. The project encountered about 24-months of delay due to the unavailability of shafts for lowering and retrieving TBMs. This paper provides a detailed analysis of the lean principles applied in Contracts Management to reduce this delay from 24 months to 18 months. The collaborative approach to lean management with clients and General consultants not only mitigated the schedule delay but also minimized TBM idle time, a critical aspect with high risks. Additionally, process optimization techniques, such as Value Stream Mapping (VSM) in the precast yard and TBM lowering cycle time reduction at the project site, are explored, showcasing the effectiveness of lean concepts in complex construction projects.
