The recent conditional clearance issued by the Commissioner for Metro Rail Safety (CMRS) to Kochi Metro Rail Limited (KMRL) marks a significant step towards ensuring the safety and reliability of the metro viaduct spanning from SN Junction to Thripunithura. While the provisional authorization allows for the operation of trains through the 1.20-km corridor, it comes with stipulations aimed at addressing critical concerns highlighted during inspections.
In a letter dated February 22, CMRS Anant M. Chowdhary underscored the importance of addressing discrepancies in camber values observed in the pre-stressed concrete (PSC) girders. The recorded higher camber values, compared to the design specifications, raised concerns regarding the structural integrity and quality control processes employed during construction.
To address these concerns, CMRS has mandated KMRL to engage experts from reputable institutions such as IITs or CSIR-SERC Chennai to reassess the design camber, evaluate safety implications, and recommend measures to enhance quality control protocols. The four-month validity period for the provisional authorization underscores the urgency of addressing these issues while ensuring the highest standards of safety and reliability.
Furthermore, CMRS highlighted discrepancies in the open web girder (OWG) construction and directed KMRL to monitor the girder’s performance closely during the initial operational phase. This proactive approach towards monitoring and addressing potential issues reflects CMRS’s commitment to ensuring the long-term safety and reliability of Kochi Metro’s infrastructure.
While the issuance of a provisional authorization letter is not uncommon in metro rail systems, KMRL remains steadfast in its commitment to upholding the highest standards of safety and operational excellence. Collaborating with experts from esteemed institutions, KMRL is poised to conduct comprehensive technical assessments and submit compliance reports within the stipulated timeframe.
Importantly, the issuance of the provisional authorization letter does not impede the commencement of commercial operations in the corridor. KMRL continues its preparations, including the finalization of the Thripunithura terminal station, ensuring a seamless transition to operational service.
As Kochi Metro embarks on this journey towards operational excellence, the commitment to safety, quality, and reliability remains paramount. Through collaborative efforts and proactive measures, KMRL is poised to deliver a world-class metro experience while prioritizing the safety and well-being of passengers and stakeholders alike. Stay tuned for further updates as Kochi Metro prepares to usher in a new era of sustainable urban transportation.
