India’s National High Speed Rail Corporation Ltd. (NHSRCL) on Friday re-invited bids to construct Bandra Kurla Complex Station of the 508.17 km Mumbai – Ahmedabad High Speed Rail (MAHSR Bullet Train) project.
This terminus station of 1.03 km long Package C1 will be built using the cut and cover method between chainage -0.255 to 0.775. The 467m long station area within it will have 6 platforms of 425m length to accommodate 16 coach trains.
The station box will consist of 3 levels – service floor, concourse and platform at a depth of 24m below ground level.
NHSRCL had originally invited bids for this package in November 2019 and cancelled it in February 2022 due to uncertainty over its construction due to an indifferent state government at the time.
- Completion Period: 1638 days (4.48 years)
- Pre-bid Meeting: August 22, 2022 at 11:00 AM
- Date & Time of Submission of Tender: October 20, 2022 at 03:00 PM
- Date & Time of Opening of Tender: October 21, 2022 at 03:00 PM
IFB Number: Package No. MAHSR-C-1
Brief Scope: Design and Const. of Civil and Buildings Works on Design-Build Lump Sum Price basis for Double Line High Speed Railway for Mumbai Underground Station, Cut and Cover Tunnel and Shaft-1 from MAHSR Km. -0.255 to Km. 0.775 at BKC in Maharashtra
The assigned contractor for C1 will also be required to build a tunnel boring machine (TBM) retrieval shaft. This is where TBMs used in Package C2 will complete their underground journey while building .
If things go according to the scheduled timeline, then I see preliminary construction work for this package starting in mid-2023 and actual construction work by 2023-end.
With this encouraging development, tender notices for 2 more packages – 20.377 km C2 (BKC – Shilphata) and 135.45 km C3 (Shilphata – Gujarat Border) in Maharashtra are pending. The last of 5 civil contracts in Gujarat was awarded earlier this year.
Land acquisition progress in Maharashtra currently stands at roughly 63%, so I reckon it’ll be a while before a notice for C3 is out. C2’s retender notice for the construction of twin tunnels should be around the corner. The appointed contractor for that will be required to use at least 3 Mega TBMs with a diameter of roughly 14.5 meters.
