NHAI signs MoU with NGI

The National Highways Authority of India signed a memorandum of understanding with the Norwegian Geotechnical Institute in Oslo on May 20, expanding technical cooperation on tunnel engineering, slope stability and highway safety. India’s Press Information Bureau said the agreement will run for five years and cover consultancy support, capacity building and knowledge transfer for national highway projects. NGI said the MoU was signed during Prime Minister Narendra Modi’s state visit to Norway and builds on ties it has maintained with India’s Ministry of Road Transport and Highways since 2017. ### Why did NHAI go to a Norwegian geotechnical institute for this? The Norwegian Geotechnical Institute said the agreement is aimed at improving the safety and reliability of highway infrastructure in “challenging mountain and tunnel environments” across India. NGI said it will provide specialized expertise in tunnel engineering, slope stability, landslide risk assessment and advanced monitoring systems, while also supporting training for Indian engineers and professionals. (pib.gov.in) The Press Information Bureau said NHAI wants to draw on NGI’s “advanced analysis methods” and international practices for the planning, design and construction supervision of complex highway projects. That includes support on geotechnical hazards that can affect roads in hilly terrain, where tunnels, cut slopes and unstable ground can raise construction and maintenance risks. (ngi.no) ### What exactly is in the agreement? The Press Information Bureau said the MoU covers consultancy services in tunnel engineering and slope stability, along with institutional capacity building. The government statement said the partnership is intended to strengthen technical capabilities for “safe, sustainable and world-class” national highway infrastructure. (pib.gov.in) NGI said the scope also includes landslide risk assessment and advanced monitoring systems. Those elements point to work beyond design review alone, extending to field observation, hazard evaluation and supervision support on difficult alignments. That reading is based on the institute’s own description of the services it will provide under the pact. (pib.gov.in) ### What does NGI bring to tunnel and slope work? NGI says it has long experience in rock engineering, hydrogeology and geotechnics for tunnels, mountain slopes and rock foundations. The institute also says the Q-system for assessing rock-mass quality and tunnel support needs was developed at NGI and is used internationally in planning and construction. (ngi.no) NGI’s published project work in Norway includes rail and infrastructure assignments involving bridge, culvert and slope stability issues. That public record helps explain why NHAI identified the institute as a technical partner for mountain highway and tunnel work. ### How does this fit with NHAI’s recent approach to geotechnical risk? NHAI has already been adding outside technical support for tunnels and slope stabilization. (ngi.no) A November 2023 NHAI press release said the authority signed a separate MoU with Konkan Railway Corporation Limited to review tunnel designs and safety aspects, conduct tunnel safety audits and suggest remedial measures where needed. (prod.ngi.no) In January 2026, NHAI also signed an MoU with the National Test House for testing support, technical committee participation and training programs for its officials, according to the Press Information Bureau. The NGI agreement extends that pattern of bringing in specialized institutions for design review, testing and capacity building. ### What comes next after the signing? (nhai.gov.in) The Press Information Bureau said the agreement remains valid for five years, giving NHAI and NGI a formal window to deploy consultancy and training support on upcoming projects. NHAI’s published FY 2025-26 project list shows multiple highway schemes above 500 crore rupees in the pipeline, providing a potential set of projects where tunnel, slope or geotechnical support could be applied.
