The C1 Package is a critical and highly complex component of the Mumbai-Ahmedabad High-Speed Rail (MAHSR) corridor, often referred to as the Bullet Train project. This package primarily covers the construction of the Bandra Kurla Complex (BKC) High-Speed Rail Station in Mumbai, which is notable for being the only underground station along the entire 508 km MAHSR route. Its underground nature, located approximately 24 meters below ground level, and its integration with Mumbai’s existing and upcoming metro lines, present significant engineering challenges. The C1 package is a testament to the ambitious nature of India’s high-speed rail aspirations, involving advanced construction techniques and meticulous planning to ensure seamless connectivity and passenger comfort in one of the world’s densest urban environments.

SYNTEGRITY was responsible for delivering comprehensive, construction-ready designs review and support for the Bandra Kurla Complex (BKC) underground station, the only underground station on the corridor. The DDC’s scope includes civil, structural and geotechnical design for the 467-meter-long station box, cut-and-cover tunnel, and the ~66-meter-deep TBM retrieval shaft.

Key responsibilities involved detailed engineering review and support of the station’s three-level structure (platform, concourse, service floor).
