Legship Gyalshing Road Tender: Balance Works on NH-510 in Sikkim (Rs 152.85 Cr)

NHIDCL is back in the market for the unfinished stretch between Legship and Gyalshing in west Sikkim, and the ₹152.85 crore Legship Gyalshing road tender closes at 3:00 PM on 21 December 2026.

Two packages, 31.37 km, second call

The scope is balance works on the existing stretch between Legship and Gyalshing on NH-510, covering design chainage km 58.840 to km 75.000 as package V and km 75.000 to km 90.210 as package VI. That is 31.37 km in all. The notice is a second call, reference NHIDCL/SKM/NH510/ Leg Gyal/PKGV VI/2026, from the National Highways and Infrastructure Development Corporation corporate office in New Delhi.

Balance works on a hill highway usually means somebody else left site. Read the schedule of quantities closely to see what is actually left standing, because retaining structures and drainage carried over from an earlier contractor can be the bulk of the money.

A seven year contract period

The portal records 2,555 days, which is seven years, so this contract carries a long maintenance tail after construction. EMD is ₹1,53,00,000 with no exemption and the tender fee is ₹23,600, on an EPC form of contract. Bids open on 22 December.

Hill road contractors comparing risk should also look at four slide zones being treated on NH-34 in Uttarakhand and the BRO slope protection packages above Tawang. The pattern is the same: slope stabilisation now costs as much as the pavement.

Machines that earn in west Sikkim

Access is the first problem. Compact excavators that can be walked along a single lane carriageway are worth more here than a bigger machine that cannot turn. Breakers for rock, tippers sized for tight hairpins, and a backhoe loader for drains and breast walls cover most of the cycle. Concrete for retaining walls comes from site mixers because transit mixer access is poor, and pavement layers need a motor grader with compactors. Build the monsoon shutdown into your rate.
