Mumbai, June 12 -- Days after scrapping tenders for two major infrastructure projects-the Thane-Ghodbunder Road tunnel and the Ghodbunder-Bhayander elevated road-the Mumbai Metropolitan Region Development Authority (MMRDA) has asked construction giant Larsen & Toubro (L&T) to submit a complete breakdown of its financial estimates. The move follows a legal tussle between L&T and the MMRDA over the awarding of the Rs.15,182.87 crore contracts to Hyderabad-based Megha Engineering and Infrastructure Limited (MEIL). L&T had challenged the MMRDA's decision in the Bombay High Court and subsequently in the Supreme Court, alleging it had been unfairly disqualified despite submitting bids that were collectively Rs.3,130 crore lower than MEIL's. In a letter dated Tuesday, MMRDA has asked L&T to furnish detailed financial documents related to both projects. These include calculation sheets, explanatory notes, rate analysis, and justifications submitted as part of the original bid. A copy of the letter reviewed by Hindustan Times shows that the MMRDA intends to archive the documents as part of official records and for transparency in the tendering process. According to L&T's bid, the firm had quoted Rs.12,052 crore for both projects-Rs.5,554 crore for the elevated road and Rs.6,498 crore for the tunnel. In comparison, MEIL's winning bid amounted to Rs.15,182.87 crore, with Rs.9,019.53 crore for the elevated road and Rs.6,163.34 crore for the tunnel. The projects are part of MMRDA's broader road expansion initiative and are seen as critical extensions of the Mumbai Coastal Road. The first involves construction of twin tunnels spanning 5.7 km between Gaumukh and Fountain Hotel junction on Thane Ghodbunder Road. The second entails an 11.42 km elevated road connecting Ghodbunder Road to Bhayander, including a bridge over the Vasai Creek. The tendering process began in July 2024. L&T submitted its technical bid in December, which was opened on January 1, 2025. However, in May, the company learned it had been excluded from the financial bidding round....
