The deadline for contractors to submit prequalification submissions for the Naitwar Mori hydropower project in northern India, which calls for major underground works as part of the turnkey package, has been rescheduled to 10 February.

Most recently, submissions to prequalify for the contract were invited by 20 January. The cutoff has been shifted by a further three weeks.
Tunnelling works on the project, to be built in the state of Uttarakhand, include excavation of a 4.3km long headrace of 5.6m width and horseshoe-shaped cross section, and a partly underground powerhouse.
There will also be a 41m deep surge tank, adits with lengths of 43m and 169m, respectively, and the tailrace may also be constructed as tunnel.
Geology along the alignment of the bore is mainly in gneisses, which are along three-quarters of the headrace.
SJVN is planning for the contract is to be completed within 36 months.
The utility is a joint venture of the Indian Government and the state of Himachal Pradesh.
