A ₹185.96 crore EPC contract takes 22.7 km of NH-117 in South 24 Parganas from a plain two-lane road to two lanes with paved shoulders, and the NH-117 widening tender closes at 11:00 AM on 7 December 2026.
Two bridges left out of the package
The length runs from km 114.975 to km 137.684. Two major bridges, roughly 1.40 km in total between km 118.848 and km 119.506 and between km 127.926 and km 128.668, are excluded from this contract, so the winner works around them and ties the new pavement into existing structures at four points.
The Regional Office at Kolkata invites the bid, reference RO-KOL/NH-117/2026-27/01, and the portal gives only 360 days. One year for 22.7 km of widening with structure interfaces is a tight programme in a district where the water table is high and the monsoon is long.
What the short period means for bidders
The estimate is ₹1,85,96,40,000. EMD is ₹1,85,96,400 at 1 per cent with a fee of ₹20,000, and bids open at 11:30 AM on 8 December. At ₹8 crore a kilometre with a twelve-month clock, this is a job for a contractor who can hold two or three fronts open and who already has plant in the Kolkata belt rather than one mobilising from outside.
NH-117 is the Diamond Harbour road and carries heavy local traffic, so traffic management is real cost. If you are weighing work in the same district, the Bhatpara sewer renovation contract is open, and the NH-114 strengthening job in Birbhum came from the same regional office on the same day.
Paved shoulders, live traffic, soft ground
Widening next to moving traffic means short working lengths and constant diversions, which is backhoe loader work as much as anything else. Excavators cut drains and build the shoulder, wheel loaders feed the plant, and compactors behind a motor grader build the crust. Soft subgrade in the delta usually means extra granular layers, so the tipper count matters more than it looks on paper.
