L&T-IHI Infra System wins ₹1,390-cr NHSRCL's steel bridge contract
The contract, involving an investment of ₹1,390 crore, has been awarded to Larsen & Toubro – IHI Infrastructure Systems (Consortium), a consortium of Indian and Japanese companies. It is estimated that about 70,000 MT of steel will be used for the fabrication of these steel bridges while Indian Steel Industries and their allied supply chains will get a big boost. Indian steel manufacturers will be providing quality steel for the fabrication of superstructures for these steel bridges.
NHSRCL has already awarded civil contracts for the construction of 64% of MAHSR alignment which includes five HSR stations (Vapi, Billimora, Surat, Bharuch, Anand/Nadiad), Train depot at Surat and One Mountain Tunnel of 350 metres. Out of the total length of 508 km, a maximum stretch of the Mumbai-Ahmedabad High-Speed Rail (MAHSR) will be covered by the viaduct, which excludes the 21 km long tunnel near Mumbai. The MAHSR alignment over viaduct (487km) will span over National Highways, Dedicated Freight Corridor Tracks (DFC), Indian Railways Tracks and rivers at many locations. Most of the viaducts are being made of concrete (PSC box, Girder). However, steel superstructures have been planned for span requirement of more than 60 meters, as beyond a point PSC structures become heavy and steel superstructures are considered to be more viable and efficient.
