NEW DELHI, INDIA (Metro Rail News): After the Delhi Metro Rail Corporation opened financial bids, Afcons Infrastructure emerged as the lowest bidder for tunnelling contract DC09 of the Delhi Metro’s Silver Line through Chhattarpur.
This 6.51 km section will connect Kishangarh Station’s east end (chainage 5356.285) with a ramp (chainage 11867.000) west of Saket G Block Station through four stations: Chhattarpur (interchange with Yellow Line), Chhattarpur Mandir, IGNOU, and Neb Sarai.
In May 2021, DMRC issued a request for proposals for this package, which was funded by JICA and had a 42-month timeframe and an undetermined cost estimate. They earlier projected the cost to be Rs. 1427.872 crore, but I’m not sure if that figure is still accurate.
Design and Construction of Twin Tunnel (Up & Down Line) by Shield TBM, Cut and Cover Tunnel box, Underground Ramp and four Underground stations namely Chhattarpur, Chhattarpur Mandir, IGNOU and Neb Sarai with Entry/Exits & Connecting subways from chainage 5356.285 mtr. to 11867.000 mtr. of Aerocity to Tughlakabad Corridor of Phase-IV of Delhi MRTS are some of the brief scopes.
we don’t know what DMRC’s current estimate for DC-09 is, and how Afcons’ bid is placed or what the next stages are.
If it falls within the DMRC’s acceptable range, a contract should be granted early next year, with construction work beginning in Q2 2022. Afcons will be expected to use at least 5 tunnel boring machines if they are awarded the contract (TBMs).
Financial bids for all four JICA-funded underground packages of Phase 4 were opened as a result of this development, with Afcons winning three of them.
