BEML Plans Indigenous Tunnel-Boring Machines to Reduce India’s Dependence on Imports

India’s expanding infrastructure programme is creating new opportunities for domestic construction equipment manufacturers, and state-owned BEML Ltd is preparing to enter a specialised segment that has largely depended on overseas technology. The company plans to develop indigenous tunnel-boring machines (TBMs), targeting growing demand from metro rail, hydropower, irrigation and underground infrastructure projects.

BEML will initially focus on smaller tunnel-boring machines with diameters ranging from 3.5 metres to 6.5 metres before gradually moving into larger equipment. Chairman and Managing Director Shantanu Roy said the company has completed its preliminary groundwork and is ready with a development plan. BEML is also onboarding a global consultant to support the initiative.

The proposed strategy comes as India seeks to reduce its dependence on imported construction machinery, particularly equipment sourced from China. The country’s growing investment in underground transportation, road connectivity and strategic infrastructure has increased the need for specialised tunnelling equipment.

Unlike conventional assembly-based manufacturing, BEML intends to develop its own technology and intellectual property. Roy indicated that the machines would be built using indigenous technology, with Indian ownership of the underlying intellectual property.

The initial focus on smaller machines reflects a phased approach to entering the market. Larger tunnel-boring machines involve more complex engineering requirements. For perspective, the machines used in the Mumbai section of India’s first bullet train project have cutter heads measuring approximately 13.6 metres in diameter. These were manufactured by Germany’s Herrenknecht at its facility in China.

Market conditions could support BEML’s expansion plans. Roy estimates that India’s tunnel-boring machine market could grow by around 12 per cent annually over the next seven to eight years, approximately twice the expected global market growth rate.

Government investment plans are also creating demand. Union Road Transport and Highways Minister Nitin Gadkari has indicated that India could invest up to $9.6 billion in tunnelling projects over the next five years. Railway and road projects across the Himalayan region are another potential source of demand.

However, developing a commercially viable domestic manufacturing capability will take time. BEML estimates that delivering its first machine could take approximately 22 months after securing a contract.

The initiative could mark an important step towards strengthening India’s domestic construction equipment manufacturing ecosystem.
