RINA Wins Surat Metro’s DDC Contract for Tunnel Ventilation & Studies

Multiple industry sources have confirmed to me that RINA S.p.A.’s Indian subsidiary has won Surat Metro Phase 1’s detailed design consultant contract for its underground section’s environment simulation studies and tunnel ventilation system (TVS).

Surat Metro’s 21.61 km Line-1 (Sarthana – Dream City) includes two underground sections totaling 7.02 km with 6 stations. Construction contracts were awarded by Gujarat Metro Rail Corporation (GMRC) in January and March:

  • 3.46 km Package CS2: Gulermak – Sam India Builtwell JV (Kapodra Ramp – Surat Railway Station)
  • 3.56 km Package CS3: J Kumar Infraprojects (Chowk Bazar Ramp – Surat Railway Station)

GMRC invited tenders for this design consultancy contract in January with an estimate of Rs. 2.40 crore and deadline of 28 weeks. I don’t have details on its list of bidders or bid values, so if someone does just leave a comment below or send me a message using the Contact page, and I can add it in.

Tender No: GMRC/DDC/UG-SES/SURAT/PH-1/2021

Brief Scope: Detailed Design Consultancy Services For Subway Environment Simulation (SES) studies & Computational Fluid Dynamics (CFD) Analysis and Sizing of Tunnel Ventilation System (TVS) and Major ECS Equipment for Entire Underground Section of SURAT MRTS PH-1 For Gujarat Metro Rail Corporation (GMRC) Limited
