Cable Bridge Surat

Construction of a new bridge on Tapi river at Athwa side was proposed in 2006. A company named S. N. Bhobe and Associates, Navi Mumbai, was selected as the designer for both of the bridge in the year 2008, The S. N. Bhobe and Associates, Navi Mumbai was designing the projects of Surat Municipal Corporation (SMC) since 2006,[3] Previously S. N. Bhobe and Associates, Navi Mumbai designed Fly Over Bridge at Nana Varachha junction, Fly Over Bridge at Kapodra Fire Station junction, Hajira - Adajan Flyover bridge and Shri Swami Dayanand Saraswati bridge across Tapi river for SMC.

Construction work of cable-stayed bridge started in 2010. The construction of cable stayed portion of bridge (River-Bridge) was contracted to a company Gammon India and the connected 3-way interchange flyover bridge at Athwa side of the main river bridge was contracted to a company Rachana construction. A company named Spectrum Techno Consultant Private Limited was appointed as Project Manager Consultant to supervise the entire construction work and to ensure that the construction was taking place as per standards.

On 25 May, 2014 the slab work was carried out at the sharp turning portion of the 3-way interchange flyover bridge.

On 10 June, 2014 workers started removing the staging plates (Formwork) from the slab, which's concrete was poured 15 days back (on 25, May). Around 8 a.m. the whole slab weighing 650 tones and 35 m length collapsed from 40 feet height.[3][4]

16 workers were buried under the slab, 10 workers have died on-the-spot and 6 sustained major or minor injuries.

Gujarat Engineering Research Institution (GERI), Vadodara was appointed to investigate the site, debris and material used for construction. Based on GERI report the material used for construction was of poor quality.

The design documents were sent to Sardar Vallabhbhai National Institute of Technology (SVNIT), Surat for verification. As per the SVNIT report there were major flaws in the design of that sharp curved part of the bridge, The sharp curvature was not taken into account by the designer, Instead the design calculation was based on the straight slab, actually the detailed analysis should be performed for that curved section. The center of gravity of that slab was outside the bridge deck and that created larger turning moment, making the slab unstable.[5][6]

Based on the reports of investigation Police Inspector of Umra Police Station lodged an FIR on 03 July, 2014 against 18 accused under the section 304 Part II, 337, 338 and 114 of the Indian Penal Code. Which includes three of S. N. Bhobe and Associates, Navi Mumbai, Five engineers from Spectrum Techno Consultant Private Limited, Four directors and three other of Rachana constructions and three engineers from SMC Bridge Cell.[3][7]

SMC Blacklisted S. N. Bhobe and Associates, Navi Mumbai and transfer the contract of design to L & T Infrastructure Eng. Ltd.

Rachana Construction was also blacklisted.[8]

Subsequently Gammon India was also blacklisted due to abandoning the incomplete work in November, 2014.[8] The remaining bridge construction contract of Cable Bridge was issued to Unique Construction, Surat.[1]

The initial plan was to complete the construction in 30 months, but collapse of one portion of 3-Way Interchange Flyover Bridge on 10 June, 2014 during the construction cause delay on this project.

The Bridge was inaugurated by Chief Minister of Gujarat Vijay Rupani on 2 october, 2018,[9] 8 years after starting the construction.
