Metro Railway’s Biman Bandar (airport) station yard will be the largest underground facility in the country once it is completed in 2021.
Metro general manager Ajay Vijayvargiya, along with senior officers, on Friday reviewed constructions at the yard and stressed on speedy work. At Biman Bandar, the station will be integrated, connecting Netaji Subhas Chandra Bose International Airport to Tollygunge, Garia, Salt Lake, Howrah and later Barasat.
“The construction methodology being used is top, down, cut and cover. It is located near the old elevated Biman Bandar station of Circular Railway, which is no longer in use. The underground The 550m-long and 41.6m-wide yard will have six tracks. Construction is going on in full swing and the diaphragm wall and plunge piles are nearing completion. Work on the top slab is also under progress,” Metro Railway CPRO Indrani Banerjee said.
A large yard is required at the airport as it is the junction of two important Metro alignments, 6.873-km Noapara-Airport stretch and the 32-km Kavi Subhash-Biman Bandar (via Rajarhat) link. The East-West Metro Corridor between Howrah Maidan and Salt Lake Sector-V is also planning a loop to the airport. “The yard will be modern, and the facilities will include stabling and reversal of rakes. There will be no need for a carshed at the airport as one already exists at Noapara,” Banerjee added.
The Noapara-Airport stretch is part of the 18.13-km-long Noapara-Barasat link. Two stations, Dum Dum Cantonment and Jessore Road, will come up between Noapara and Airport. Nearly 70% work at these two stations have been completed. There was some delay soon after work on the project started as Airports Authority of India (AAI) sought time to shift utility cables. Viaduct for the project has been completed for 2.48 km. Beyond this, substructure has been completed along a 1.1-km stretch.
“There has been good progress in this project in 2018-19. The overall financial progress was 23.49%. Of this 14.4% was achieved in 2018-19. The expenditure in the first three months till June 2018 was Rs 30.89 crore. But for completion on time, acquisition of 750 sq m land and demolition of three residential buildings in Digla mouza will be required,” another official said.
