Based on the projects tracked by The research, tunnels spanning a length of 1,265.85 km have either been constructed or are under construction using D&B and NATM methods of tunnelling.
The tunnelling market in India is mostly consolidated, with a few big contractors having the largest market share. In terms of length, close to 75% of the tunnels (887 km; built by individual contractors) were implemented by 14 contractors, while the remaining were built by 46 contractors.
The quality of construction material used in tunnelling has evolved over the years. The growing complexity of tunnel construction in the Himalayan and Peninsular regions has necessitated the use of new and advanced materials. Currently, tunnelling contractors are deploying various types of new and innovative construction materials such as active steel anchor, passive anchor, expandable friction bolt, self-drilling rock bolt, mechanical single bolt, etc.
Over the next 3-4 years, between Rs 845-1,015 billion will be spent on procuring equipment and machinery for upcoming tunnel projects. Besides, investments in the range of Rs 780-985 billion will be spent on procuring construction materials for these upcoming projects.
Going forward, the outlook for the tunnel development market is promising and will be largely driven by the central government’s focus on infrastructure development. However, there are many factors that can slow down implementation and execution. These include geological complexities, inadequate investigations, deficiencies in contract documents, complexities of the Himalayan region and the Western Ghats, safety risks, etc.
The data sources in this report is both primary and secondary. The primary data is obtained from sources such as related ministries, industry experts, private companies, Conferences organized by us for the related sector etc. The secondary sources include annual reports of companies, industry associations, paid databases, web sites, etc. The analysts and researchers combine the information from these primary and secondary sources with their industry expertise to synthesize the data presented in the report. Surveys and interviews are also conducted for this research. For the surveys, Interviews with key players and relevant people in the sector are mainly conducted. They are mostly via telephonic as well as personal interviews.
