NHAI Tunnel Tender: ₹6,969 Cr Dwarka Expressway Project Contractors Must Track
A ₹6,969 Crore Tunnel Is Coming: The NHAI Tunnel Tender to Watch
On July 1, 2026, the Cabinet Committee on Economic Affairs (CCEA) approved one of Delhi’s most significant road-infrastructure projects in years: an 8.1 km, six-lane road tunnel connecting the Dwarka Expressway with Nelson Mandela Marg in Vasant Kunj, at an estimated cost of about ₹6,969 crore under the Hybrid Annuity Mode (HAM). For large infrastructure and EPC contractors, this signals a high-value NHAI tunnel tender on the horizon — and the firms that prepare now will be best placed to compete when the formal Request for Proposal is floated.
This guide breaks down exactly what has been approved, why the project matters, what the HAM model means for bidders, and how contractors and suppliers can position themselves for the upcoming NHAI tunnel tender. Whether you are a lead EPC bidder, a specialist tunnelling firm, or a sub-contractor, this is the Delhi-NCR opportunity to have on your radar.
Important — status of this project: As of early July 2026, this is a CCEA cabinet approval, not yet a floated construction tender. The ₹6,969 crore figure is the sanctioned project cost reported by multiple outlets (Business Standard, News9, Fiinews) following the July 1, 2026 approval. The formal NHAI tunnel tender — with contractor eligibility, EMD, packaging, and timelines — is expected to follow. Always verify the exact scope and terms against NHAI’s official Request for Proposal once published. Figures here are drawn from public reporting of the cabinet approval.
Key Takeaways
- CCEA approved an 8.1 km, six-lane road tunnel linking Dwarka Expressway (NH-248BB) with Nelson Mandela Marg, Vasant Kunj, on July 1, 2026.
- The estimated project cost is about ₹6,969 crore under the Hybrid Annuity Mode (HAM).
- The NHAI tunnel tender (construction RFP) is expected to follow the cabinet approval.
- The alignment includes a 3.14 km tunnel, plus main carriageway, approach ramps, elevated, and at-grade sections.
- It will improve connectivity between West and South Delhi, benefiting traffic from Gurugram, Dwarka, and IGI Airport.
- Large infra and EPC firms should prepare eligibility and track NHAI channels now to be ready when the tender is floated.

What Exactly Has Been Approved
The approved project is more than a simple tunnel — it is an integrated 8.1 km corridor. According to reporting of the cabinet approval, the alignment starts at the Shiv Murti Interchange on the Dwarka Expressway and ends before the intersection of Nelson Mandela Marg and the Mahipalpur-Chhatarpur Road. The length is made up of a main carriageway, a tunnel section of around 3.14 km, tunnel approach ramps, an elevated stretch, and an at-grade road, with additional structures such as a flyover and an elevated U-turn planned along the corridor.
This mix of tunnelling, elevated, and at-grade work is exactly why the eventual NHAI tunnel tender will demand serious engineering credentials — it is not a straightforward road contract, but a complex urban-infrastructure package.
Why This Project Matters
The tunnel is designed to relieve some of Delhi-NCR’s most congested corridors and strengthen airport connectivity. Understanding its strategic value helps explain why it is a national priority — and why the tender pipeline behind it is worth tracking.
1
West–South Delhi Link
It provides faster connectivity between West and South Delhi, easing pressure on already congested surface roads through Mahipalpur and Vasant Kunj.
2
Airport & Gurugram Access
Traffic from Gurugram, Dwarka, and IGI Airport toward South Delhi benefits directly — valuable for airport users, cargo, and business travellers.
3
Network Integration
It is designed to integrate with the proposed AIIMS-Mahipalpur elevated corridor and the wider UER-II and Dwarka Expressway network.
Employment and economic impact: Beyond mobility, projects of this scale generate substantial employment during construction — reporting of the approval cites lakhs of person-days of direct and indirect employment. For the contracting ecosystem, that translates into demand for manpower, machinery, materials, and specialist services across the full build period.
What Hybrid Annuity Mode (HAM) Means for Bidders
The project’s delivery model matters as much as its size. Under Hybrid Annuity Mode, the risk and financing are shared between the government and the private concessionaire — which shapes who bids and how.
| HAM Feature | What It Means for the Contractor |
|---|---|
| Government Funds a Share | A portion of the project cost is typically paid by the government during construction, reducing the private partner’s upfront financing burden |
| Private Partner Funds the Balance | The concessionaire arranges the remaining finance and executes construction |
| Annuity Repayment | The private partner is repaid through annuity payments over the operation period, along with interest |
| Shared Risk | Risk is split between government and concessionaire, making HAM more attractive than pure BOT for many large firms |
Because HAM lowers the upfront capital hurdle compared with pure Build-Operate-Transfer models, it typically draws strong interest from established infrastructure players — which means the eventual NHAI tunnel tender is likely to be competitive at the top end.
Who Can Bid — and How Smaller Firms Participate
A tunnel package of this value and complexity is aimed at major infrastructure and EPC companies. But the opportunity extends well beyond the handful of firms that can bid as lead concessionaires.
| Typical Requirement for Lead Bidders | What to Expect |
|---|---|
| Turnover | Significant annual turnover thresholds befitting a multi-thousand-crore project |
| Experience | Proven track record in similar large-value highway and tunnelling works |
| Technical Capability | Specialised tunnelling expertise, equipment, and qualified personnel |
| Financial Capacity | Ability to arrange HAM financing and furnish substantial bid security |
| Registration & DSC | Registration on NHAI and central procurement systems, with a valid digital signature |
Opportunities for smaller firms: Even if you cannot bid as the lead concessionaire, a project of this scale creates a deep sub-tier pipeline — sub-contracting packages, joint-venture roles, and supply of materials, equipment, and specialist services (tunnel lining, ventilation, electrical, safety systems, and more). Positioning as a reliable sub-contractor or supplier to the eventual winner is a realistic route in for MSMEs and specialist firms.
How Contractors Should Prepare for the NHAI Tunnel Tender
Because this is an approved project with the tender still to follow, the smart move is to prepare now rather than scramble when the RFP appears. Here is how to get ready.
1
Get Registered & DSC-Ready
Ensure your firm is registered on NHAI and central procurement systems with a valid Class 3 digital signature, so you can access and bid on the tender the moment it is floated.
2
Assemble Eligibility Evidence
Compile turnover records, similar-work and tunnelling experience certificates, and financial documents now — these are what clear the technical bid on complex packages.
3
Line Up JV & Financing
For HAM, arrange financing capacity and, if needed, joint-venture partners with complementary tunnelling or financial strength before the RFP window opens.
4
Map Your Sub-Tier Fit
If bidding as a supplier or sub-contractor, identify exactly where your capability fits — tunnelling systems, materials, electrical, ventilation, or safety — and prepare your pitch.
5
Track NHAI & Corrigenda
Monitor NHAI channels for the RFP and watch for corrigenda once it is live. See our guide on tracking tender corrigenda.
6
Nail Compliance Early
High-value tenders are won on compliance as much as capability. Build your checklist now — see our tender compliance checklist.

Frequently Asked Questions
What is the NHAI Dwarka Expressway tunnel project?
The NHAI Dwarka Expressway tunnel project is an approved 8.1 km, six-lane road tunnel connecting the Dwarka Expressway (NH-248BB) with Nelson Mandela Marg in Vasant Kunj, Delhi. The Cabinet Committee on Economic Affairs (CCEA) approved it on July 1, 2026 at an estimated cost of about ₹6,969 crore under the Hybrid Annuity Mode (HAM). It is designed to improve connectivity between West and South Delhi and benefit traffic from Gurugram, Dwarka, and IGI Airport. The construction tender is expected to follow the cabinet approval.
How much is the NHAI tunnel tender worth?
The project has been approved at an estimated capital cost of around ₹6,969 crore (reported precisely as about ₹6,969.67 crore) under the Hybrid Annuity Mode. This figure is the sanctioned project cost following CCEA approval; the exact value, packaging, and terms of the construction tender will be confirmed when NHAI floats the formal Request for Proposal. Contractors should confirm the tender value against the official NHAI notification once it is published.
What is Hybrid Annuity Mode (HAM) in NHAI projects?
Hybrid Annuity Mode (HAM) is a public-private partnership model NHAI uses for highway projects. Under HAM, the government typically funds a portion of the project cost during construction, while the private developer arranges the balance and is repaid through annuity payments over the operation period along with interest. HAM shares risk between the government and the concessionaire, which is attractive to large infrastructure and EPC firms because it reduces the private partner’s upfront financing burden compared with pure BOT models.
Who can bid for large NHAI tunnel and highway tenders?
Large NHAI tunnel and highway tenders are typically open to established infrastructure and EPC companies that meet stringent eligibility criteria — significant annual turnover, demonstrated experience in similar large-value highway or tunnelling projects, financial capacity, and technical capability including specialised tunnelling expertise. Bidders usually need to register on NHAI and central procurement systems, hold a valid digital signature, and furnish substantial bid security. Smaller firms often participate as sub-contractors, joint-venture partners, or suppliers rather than lead bidders.
How can contractors track the NHAI tunnel tender when it is floated?
Contractors can track the NHAI tunnel tender by monitoring NHAI’s official tendering channels and the central procurement portals where NHAI publishes its Requests for Proposal, along with NHAI’s project announcements. Because a cabinet-approved project can take time to convert into a floated tender and may be issued in packages, firms often use a tender-tracking platform that consolidates NHAI and infrastructure tenders — with alerts on new tenders and corrigenda — so they are ready to respond the moment the RFP is published.
