NHIDCL has opened bids for a Rs 3,567.51 crore twin-tube tunnel under the Sinthan Pass between Singhpora and Vailoo on NH-244 in Jammu and Kashmir, closing on 10 November 2026.
A tunnel to keep Kishtwar and Anantnag connected all year
NH-244 crosses the Sinthan Pass on the Kishtwar-Vailoo-Khanabal section, and snow shuts the pass for months every winter. The job is to build a uni-directional twin-tube tunnel between Singhpora on the Kishtwar side and Vailoo on the Kashmir side, with its approach roads, so the route stays open year round. National Highways and Infrastructure Development Corporation is the inviting agency and the contract is EPC. The tender was published on 10 September 2026.
Who can bid, and who else gets work
Only contractors with Himalayan tunnelling experience will get past the qualification stage, typically large EPC firms or joint ventures with NATM or drill-and-blast track records from projects such as Zojila, Z-Morh or the Chenani-Nashri tunnel. The approach roads, muck disposal, slope protection and camp works are where regional contractors from Kishtwar, Doda and Anantnag find sublet packages, since they know the short working season and the access roads.
EMD check
The EMD is Rs 35,67,51,000, which is exactly 1% of the estimate. The tender fee is Rs 4,24,800.
Equipment on a mountain tunnel
Drill jumbos and rock bolters at the faces, shotcrete machines, and excavators and loaders mucking out behind them. Low-profile dumpers and tippers carry the muck to disposal sites. The approach roads bring excavators with breakers, dozers and rollers, and the tunnel lining needs batching plants, transit mixers and concrete pumps, plus gantry formwork.
