Project Insight - Global Tunnel Construction Projects (Q2 2025)

Summary

This report provides a detailed analysis of tunnel construction projects globally, based on projects tracked by GlobalData.

The global tunnel construction projects pipeline, as tracked by GlobalData, stands at $1.32 trillion, comprising projects at all stages of development from announcement to execution. The total pipeline value reflects the overall value of projects that are either entirely tunnels or that have tunnels as an integral part of the work. The project pipeline includes tunneling works across a multitude of sectors, primarily road and railway development, water, and sewerage works, as well as major tunneling associated with power and oil and gas developments. The transport infrastructure sector, which includes the road and rail sectors, dominates the global pipeline of tunnel works, accounting for $1.2 trillion of the global project value; an 87.2% share. The construction of water and sewage tunnels accounts for the second-largest proportion of global project value, at $137.5 billion.

Scope

• The report provides analysis based on GlobalData's construction projects showing total project values and analysis by stage and funding for all regions. The top 20 projects per region are listed giving country, stage, value of projects. Ranked listings of the key operators for the sector are also provided showing the leading contractors, consulting engineers and project owners.

• Gain insight into the development of the tunnel construction sector.
• Assess all major projects by value, start date, scope and stage of development globally, for the regions to support business development activities.
• Plan campaigns by country based on specific project opportunities and align resources to the most attractive markets.
