Northern Railway is finishing the grade separator on the Daya Basti to Azadpur section, and the Dayabasti grade separator tender closes on 14 September 2026 at ₹73.17 crore.
What the job covers
This is the balance work on the Daya Basti grade separator in north Delhi, tendered by the Dy. Chief Engineer, Construction, Shakur Basti. The notice names earthwork and blanketing, retaining walls, PSC girders, steel girders, bridges and associated miscellaneous work. Reference number is 435-ACS-c-SSB and the portal estimate is ₹73.17 crore. A grade separator here removes a conflict point on one of the busiest approaches into Delhi, so possession windows and traffic blocks shape the programme far more than the quantity of concrete does.
Who should bid
Earnest money is ₹1,46,33,100, two per cent of the estimate to the rupee, with no tender fee. The work suits a contractor who has launched girders inside a live railway corridor before. Doing it in Delhi adds two constraints worth pricing properly: night blocks and the paperwork that comes with them, and restricted site access in a built-up area where there is nowhere to stack a casting yard. Firms coming off metro or ROB packages in the National Capital Region will find the shape familiar.
Machines you will need
Girder work leads the machine list. PSC and steel girders need heavy hydraulic cranes, and the launching scheme decides whether you bring in one large crawler or a pair of mobile cranes working a short block. Earthwork and blanketing on the approaches call for excavators, tippers and vibratory compactors. Retaining walls mean concrete on site: transit mixers, a concrete pump and a backhoe loader keeping services and formwork moving between pours.
Key facts

Reference no.
435-ACS-c-SSB
Issuing authority
Dy. Chief Engineer, Construction, Shakur Basti, Northern Railway
A structure that carries one line or road over another so the two no longer cross at the same level. It removes the delay and the risk that come with a level crossing on a busy corridor.
Why is this called balance work?
Part of the separator is already built. This contract covers what is left, which the notice lists as earthwork and blanketing, retaining walls, PSC and steel girders, bridges and miscellaneous items.
How much earnest money is needed?
₹1,46,33,100, two per cent of the ₹73.17 crore estimate, and there is no tender fee. Railway works of this size use the same two per cent rate.
What decides the programme on a job like this?
Traffic blocks. Girder launching over a live section happens inside sanctioned windows, so the number of blocks you get and their length matter more to the schedule than machine capacity does.
