The government has reiterated its focus on infrastructure development time and again. In the recent past, greater emphasis has been given to the development of water and sewerage, road, irrigation, railway, metro rail and hydropower […]
Tunnel development in India has accelerated over the past decade or so. This is driven by increased investments in the hydropower, railway, road and highway, metro rail, and water and sewerage sectors. According to India […]
Mechanised techniques are gradually replacing traditional or non-mechanised methods of tunnel construction in the country. Advanced, technology-driven, efficient and cost-effective methods of tunnelling are being deployed in almost all infrastructure sectors. However, despite the advances […]
With significant momentum in the infrastructure space, developers increasingly need to execute tunnelling projects. Tunnels are required to be constructed across various projects in the railway, road, metro, water supply and sewerage sectors. While several […]
The tunnelling sector in India is currently served by both domestic and foreign players. Most of the contractors have a presence in all key tunnelling segments – hydropower, railways, metro rail, roads and highways, irrigation, […]
According to India Infrastructure Research, the Indian tunnelling equipment market (comprising completed and ongoing projects) is estimated to be worth Rs 400 billion-Rs 700 billion. This cost varies with the type of tunnelling method used […]
Materials used in tunnel construction vary significantly with the type of tunnelling method or technique deployed. Generally, non-mechanised techniques such as drill-and-blast entail a higher material cost as compared to mechanised techniques. The different types […]
While significant progress has been made in the Indian tunnelling sector in recent times, several issues continue to impede growth. Three key issues – geological complexities, poor contracting practices and safety issues – plague project […]
Tunnel construction in India has picked up pace in recent years with greater impetus being given by the government to key infrastructure sectors such as hydropower, railway, road, metro rail and irrigation, water supply and […]
The tunnelling market is largely dominated by the hydropower, railway, road and highway, metro rail and irrigation, water and sewerage sectors. […]
In India, the construction of tunnels is primarily undertaken by domestic contractors with very few foreign players present in the segment. […]
Tunnel development in India is driven by investments in the hydropower, railway, road and highway, metro rail, and water and sewerage sectors. […]
The equipment and technology market can broadly be divided into three categories – drill and blast equipment, tunnel boring machines (TBMs) and other equipment. Tunnelling equipment is usually acquired through purchase of new machinery, purchase […]
Tunnel construction requires various types of materials including explosives, concrete, steel, shotcrete material, lattice girders and rock reinforcement supplies. Materials used in tunnelling vary with the design and construction methods chosen for each project. The […]
Significant progress in technology as well as increasing focus on cost efficiency and safety have necessitated vast changes in the methods and techniques employed in tunnelling. […]
