MoRTH flags poor DPR behind delays in long tunnel projects, calls for prior consultation, Pg13.

Key Highlights:

• MoRTH (Ministry of Road Transport and Highways) addressed delays in tunnel projects exceeding 1.5 km due to inadequate Detailed Project Reports (DPRs).
• Prior consultation with the Tunnel Zone is now required during the feasibility/DPR preparation stage to expedite approvals.
• IRC:SP:91-2019 (Indian Roads Congress guidelines) should be followed for tunnel construction on national highways.
• A Standard Operating Procedure (SOP) was issued on September 2 to improve tunnel alignment studies and approvals.

Detailed Insights:

• Poor geo-technical investigation during DPR preparation is a primary cause of delays in long tunnel projects.
• Early consultation with the Tunnel Zone helps ensure that necessary investigations and assessments are conducted according to guidelines.
• Tunnels are crucial for avoiding snowbound areas, eco-sensitive zones, water bodies and congested areas, enhancing connectivity.
• Detailed investigation and planning are vital due to the high costs and risks associated with tunnel construction.
• Executing agencies are directed to include IRC guidelines in the preparation of tunnel DPRs to mitigate geological risks.

Key Concepts Involved:

• Detailed Project Report (DPR): A comprehensive report outlining project details, cost, and feasibility.
• Geo-technical Investigation: Study of subsurface soil and rock conditions to assess geological risks.
• Indian Roads Congress (IRC): Apex body of highway engineers in India providing technical guidelines.
