Kaiga Drainage Tender: Lining, Retaining Walls and Hydraulic Structures at Units 5 and 6 (Rs 334.01 Cr)

Before two new reactor units can be built at Kaiga, the water has to be told where to go: NPCIL has ₹334.01 crore out for drainage lining, retaining walls and hydraulic structures, and the Kaiga drainage tender closes at 5:00 PM on 12 November 2026.

Drainage works for Kaiga 5 and 6

The scope is construction of lining, retaining wall, hydraulic structures and allied works for the water drainage arrangement at Kaiga 5 and 6. Nuclear Power Corporation of India Limited is the inviting authority through its centralised tendering cell and the Kaiga Generating Station site, reference CPPP/2026/125, on an item rate contract with 1,095 days.

Kaiga sits in the Western Ghats in Uttara Kannada, one of the wettest parts of Karnataka. Site drainage at that rainfall is genuine hydraulic engineering: lined channels sized for monsoon flows, retaining structures holding cut slopes, and energy dissipation where the water leaves the site.

Three years, item rate, no fee

The estimate is ₹3,34,00,67,770. The EMD is ₹93,80,136 with no exemption allowed, and the portal shows no tender fee. Bids open at 11:30 AM on 14 November 2026. The notice went up on 30 September, so the window is nearly closed.

Three years on a nuclear site means working to a documentation and quality regime that adds real cost, along with security clearance for every person and machine. Contractors who have not worked inside a licensed site before routinely underprice that. Karnataka also has the NH-75 blackspot grade separators and the Nethravathi bridge between Kotepura and Bolar live.

Wet-ground earthwork and a lot of concrete

Channel lining and retaining structures over three years mean steady, repetitive work rather than peaks. Excavators cut and trim the channel sections and foundations, transit mixers feed lining and wall pours from an on-site plant, and a crane handles shuttering, precast units and reinforcement cages. Compactors and a backhoe loader cover backfill, haul roads and the smaller structures. In Ghat rainfall the working season is short and the access tracks need constant attention, so a motor grader earns its keep on site roads alone.
