The global tunnel boring machines market size was valued $5,476.0 million in 2019 and is expected to reach $7,552.1 million by 2027, growing at a CAGR of 6.0% from 2020 to 2027. Tunnel boring machine (TBM) is used for tunnel excavation through different rocks and soils. Tunnel boring machines are majorly used for the construction of excavation of coal mines, and tunnels. An increase in infrastructure development for railway and highway is expected to drive the growth of the global tunnel boring machine market. An increase in the adoption of tunnel boring machines for water supply & disposal, pipelines for oil & gas, and hydropower projects, is anticipated to cater to the growth of the tunnel boring machine market. TBM eliminated operational time required for construction activities as compared to other conventional methods, thereby increasing its adoption. Moreover, an increase in spending on road infrastructure and railway projects is expected to boost the growth of the global tunnel boring machine market. An increase in government spending on pipeline railways and road infrastructure around the globe, is anticipated to drive the growth of the global tunnel boring machine market. For instance, in July 2019, the Italian government invested $33.79 billion on a railway infrastructure project.
