In the primary research process, both supply-side and demand-side stakeholders were interviewed to gather qualitative and quantitative data. Supply-side sources included CEOs, Heads of Engineering, Project Directors, and Business Development heads from companies that make TBM, supply parts, and provide tunneling services. Demand-side sources included project managers from top construction companies (EPC companies), mining operations directors, chief engineers from metro and transit authorities, procurement heads from railway companies, and developers of utility infrastructure. Primary research confirmed order backlogs and delivery times, validated market segmentation by machine type and geology, and gathered information on how cutterhead technology is being used, how project bidding works, and after-service maintenance contracts.

Global market valuation was derived through capital equipment procurement analysis and project pipeline tracking. The methodology included:
Identification of 35+ key TBM manufacturers and system integrators across North America, Europe, Asia-Pacific, and Latin America
Product mapping across slurry TBM, earth pressure balance shield, hard rock TBM, multi-mode TBM, and specialized shield configurations
Analysis of reported and modeled annual revenues specific to tunnel boring equipment portfolios, including cutterhead systems and auxiliary equipment
Coverage of manufacturers representing 75-80% of global market share in 2024
Extrapolation using bottom-up (active tunnel project pipeline × estimated TBM deployment costs by country/region) and top-down (manufacturer revenue validation across machine types) approaches to derive segment-specific valuations for soft ground, hard rock, and heterogeneous ground applications
