India: local-content preference margin in Northeast Frontier Railway Dimapur-Kohima tunnel-protection tender

Mechanism

Northeast Frontier Railway's Construction Organisation floated an EPC tender (CE/CON/DK/EPC/2026/01) for protection works on a tunnel along the Dimapur (Dhansiri)-Kohima (Zubza) new BG line — part of the broader ~82.5 km, ~21-tunnel Dimapur-Kohima project connecting Nagaland's capital to the rail network. As with other NFR hill-section tenders in this cluster, the bid-evaluation criteria apply a preference margin to domestic ("Class-I local supplier") bidders under the 2017 Make in India procurement order, disadvantaging foreign construction firms and material suppliers competing for the INR 306.10 crore contract.

Severity is set to 2 (quant) reflecting the disclosed contract value relative to peer tenders in this cluster, which range from roughly INR 100 crore to INR 30,000+ crore.

Downstream implications

• One more data point in NFR's systematic use of Make in India

preference margins across its entire Northeast hill-rail build-out (now 60+ tenders logged in the em-trade-facilitation-logistics theme), not an isolated policy event.

• Foreign EPC contractors and construction-materials suppliers face a

structural, recurring disadvantage bidding into India's Northeast rail-connectivity programme.

Open questions

• Exact bid-evaluation preference percentage margin applied (GTA's

free-tier record does not disclose it; DPIIT's order sets a general framework with sector-specific margins set by the procuring entity).

• Winning bidder / contract award outcome not yet public as of filing.
