August 18, 2021 Original Post: 6 construction firms / consortia have submitted bids to build Package DC07 of the 23.622 km Silver Line after the Delhi Metro Rail Corporation (DMRC) today opened technical bids.
This 6.981 km section on the eastern side of the Silver Line will connect Sangam Vihar Station’s east-end and Sarita Vihar Depot via 3 stations at Maa Anandmayee Marg, Tughlakabad Railway Colony, and Tughlakabad where it will form an interchange with the Violet Line’s station built in Phase 2.
Financed by JICA, DMRC invited tenders for this tunneling contract in May 2021 with a 42 month deadline and an unknown estimate. They had previously estimated it to cost Rs. 1365.51 crore, but that was up to only Tughlakabad Station. The package’s scope now includes tunnels all the way up to the existing Sarita Vihar Depot, which will be augmented to stable and maintain the Silver Line’s train-sets.

Do you expect STEC to be disqualified in technical evaluation given the criticism govt had to face the last time they were awarded a contract.
Things have cooled down since Galwan, but you never know how this is going to play out. I wouldn’t be surprised if they’re disqualified on a random parameter.
Actually new Minstry of finance circular has given then leeway. The companies from country sharing borders with India have to show security clearance from appropriate authority before getting LoA. I am not sure if they have already acquired the permissions.
Is there any scope of use of Poly Macro Fibres in Shotcrete of any tunnels?
Cross-passages will be built using NATM where shotcrete will be used, so there’s a possibility.
Is the entire silver line underground or otherwise what is its total i would be thankful!
4.28 km Package DC-04 is elevated from Saket – Sangam Vihar:
When can we expect the first phase 4 operational line and which one will it be? Most likely not before 2024. Is it?
Will most likely be the Pink Line’s 12 km extension. 2024-end sounds about right.
NHSRCL had opened tecnical bids for T-2 package of MAHSR. Can u please inform which are the 4 bidders.
Also T-3 package tender notice is out as well.
U haven’t posted any blog since a while, hope you are doing well.
Thanks – doing good. Just a little busy these days.
