“NHSRCL is approaching land acquisition with care and without harming any person’s or families’ interest,” Gaur says, while admitting challenges like disputed land pockets, missing or incomplete land records. He informs that bids have been invited for the construction of about 69 per cent (348 kms) of the total alignment of 508 kms, including 21 kms of underground tunnel (including 7 km undersea tunnel), five elevated stations and one depot at Surat. “The tenders will be finalised in this year and the physical work is likely to start in many locations by end of this year,” he adds.
