    What is the difference between bid and tender?

    • TMRG says:

      ‘Tender’ refers to the overall application submitted by infra companies in response to the operator’s notice for procuring a service, product or piece of infrastructure. This application comprises of different sub-documents: work experience, financial standing, bank guarantee, technical bid and financial (price) bid etc. As per the rules laid down by international lending institutions and metro operators, each bidder is first evaluated & filtered out on eligibility, then technical bid and finally the financial (price) bid.

      Both terms can be used interchangeably. I primarily use ‘bid’ in the title to keep it short.

    Hi TMRG

    Thanks for the update

    When will the tender work start for Phase II. I believe Phase II work should start in parallel to Phase 1 extn. What is the latest status on Phase II?

      Hi, the project requires TN govt’s cabinet approval. Preliminary work to appoint a general consultant (GC), detailed design consultant (DDC), and different surveys/studies (eg. topographical survey, environmental impact assessment etc.) can only start after that.

      Construction work is at least 2 years away from beginning.

    when will the koyambedu underground section open ?

    • TMRG says:

      CMRL is waiting for local ministers and the MoUD to agree on an inauguration date. There’s some minor work pending, but that’s not a show stopper.
