NHSRCL 28 Bridges P4 Package for Bullet Train to Use 70KT Steel

National High Speed Rail Corporation Limited has awarded Contract for Procurement and Fabrication of 28 steel bridges super structures for crossing

National High Speed Rail Corporation Limited has awarded Contract for Procurement and Fabrication of 28 steel bridges super structures for crossing over railway lines, rivers, highways, road and other structures under P-4 Package for Mumbai Ahmedabad High Speed Rail Corridor. The contract of award Value of INR 1390 crores has been awarded to Larson & Toubro & Japanese IHI Infrastructure Systems Consortium. It is estimated that about 70,000 tonnes of Steel will be used for the fabrication of these steel bridges.

Out of the total length of 508 kilometres, a maximum stretch of the Mumbai Ahmedabad High-Speed Rail will be covered by the viaduct, which excludes the 21 kilometres long tunnel near Mumbai. The Mumbai Ahmedabad High-Speed Rail alignment over viaduct of 487 kilometres will span over National Highways, Dedicated Fright Corridor Tracks, Indian Railways Tracks and rivers at many locations. Most of the viaduct is being made of concrete PSC box & girders. However, where the span requirement will be more than 60 meters, steel superstructures have been planned, as beyond a point PSC structures become heavy and steel superstructures are considered to be more viable and efficient.

In total, 28 steel bridges with individual spans varying from 60 meters to 130 meters will be constructed for the project. The length of all the steel bridges put together will be approximately 4.5 kilometres. For this purpose, at initial stages, the steel super structure work was assigned to Japan Lead Companies, as the job required construction of steel super structures bridges of high-quality Japanese standards for high speed railway.
