Government Forms Expert Panel to Oversee Tunnel Projects Across India

In light of recent tunnel construction mishaps, notably the Silkyara tunnel incident, the Ministry of Road Transport and Highways (MoRTH) has acknowledged the need for a thorough review of the current practices in the investigation, design, and construction phases of tunnel projects. The goal is to identify and resolve existing problems while ensuring compliance with both national and international guidelines during the preparation of Detailed Project Reports (DPR).

To address these challenges and enhance the quality of tunnel projects, the Ministry has established a collaborative framework involving academic institutions and government organizations. This framework focuses on various aspects such as geological, geo-technical, and geophysical investigations, design, safety audits, instrumentation, and monitoring of tunnel projects.

Additionally, the MoRTH has constituted an advisory panel comprising experts from ONGC, RVNL, and THIDCL to provide specialized guidance during the appraisal of long tunnel projects (those exceeding 1.5 km in length).

As per the new guidelines, proposals for long tunnel projects on National Highways (NHs) must now be submitted to the Directorate General (Road Development) and Special Secretary [DG(RD)&SS] for a comprehensive technical review and expert evaluation by the advisory panel before they proceed to appraisal stages like SFC/EFC/PIB/PPPAC. The submissions should include detailed geological, geotechnical, and geophysical studies, alignment reports, tunnel design (including electro-mechanical works), and plans for instrumentation and safety measures during construction and operation, along with precise cost estimates.

This initiative, mandates greater technical scrutiny and adherence to safety standards, thereby minimizing risks and preventing further mishaps.
