YFC Projects Pvt. Ltd. today began casting 28 meter long U-girders to build the elevated viaduct for a 4.28 km section of Delhi Metro Phase 4’s 20.2 km Aerocity – Tughlakabad Line at their casting yard located in Pushp Vihar.
YFC Project’s Package DC-04 (Sangam – Saket G-Block) is the third section of the 61.679 km (and growing) Delhi Metro Phase 4 project on which work commenced earlier this year through a Rs. 726.08 crore contract awarded by the Delhi Metro Rail Corporation (DMRC) in December 2019 with a deadline of 36 months.
This package combined with 3 other underground civil packages, DC-07, DC-08 & DC-09 (see package details), will form Delhi’s newest 20.201 km metro line connecting Aerocity – Mehrauli – Tughlakabad through 15 stations. The DMRC has not yet announced its official colour or line number, but it is likely to be numbered as Line-10.
YFC’s scope of works includes building a 6-lane double-decker viaduct on Mehrauli – Badarpur Road, an underpass at Saket G-Block, another 2 lane underpass from Mehrauli-Badarpur Road to Lal Bahadur Shastri Marg, emergency siding lines and four elevated stations at Sangam Vihar, Khanpur -Devoli, Ambedkar Nagar and Saket G Block.
Per DMRC’s FB post:
U-Girders are precast pre-tensioned, U-shaped girders on which track laying can be done immediately. These girders are readied in the casting yards and brought to the sites.
The casting work of these u-girders requires meticulous precision and planning. Absolute care has to be taken regarding the maintenance of all measurements and technical parameters during the casting process. At the casting yard in Pushp Vihar, four u-girder casting beds have been set up. A dedicated quality control laboratory has also been set up to monitor all quality-related parameters.
Images of the yard being setup back in May can be viewed here.
4.28 km DC-04 is the only elevated section on the Aerocity – Tughlakabad line. The rest three packages are underground and the publishing of their tender notices along with the Magenta Line’s DC-05 (Derawal Nagar – RK Ashram) – to wrap up the tendering process for the priority 61.679 km routes – is dependent on the Japan International Cooperation Agency (JICA)’s approval.
