India’s NHPC Ltd. has issued another solicitation for completion of civil works of a headrace tunnel of the 800-MW Parbati 2 hydroelectric project, this time specifying a drill and blast method plus hydro-mechanical works. Bids are due November 23.
NHPC said questions were due October 22 with a pre-bid meeting set October 26.
In a separate tender, NHPC again extended the deadline for bids for completion of headrace tunnel civil works including excavation by tunnel-boring machine (Lot PB 2A) at Parbati 2 on the Parbati River in India’s Himachal Pradesh State.
