Asia’s infrastructure future is being built underground. Across megacities and mountain corridors, tunnel construction is reshaping how the Asia Pacific region moves people, connects economies, and engineers its way through the most challenging terrain on earth.
InnoTrans Asia 2027 brings together the full spectrum of tunnel engineering, underground construction, TBM technologies, railway tunnel engineering, and metro tunnel systems under one roof.
InnoTrans Asia delivers the platform, the audience, and the commercial opportunity you need.
The Tunnel Construction segment at InnoTrans Asia covers the full lifecycle of underground infrastructure, from early-stage geological engineering and project design through to tunnelling machinery, safety systems, and long-term maintenance technologies.
With cities expanding vertically and horizontally at extraordinary speed, land scarcity, urban congestion, and climate pressures are pushing governments and developers to build beneath the surface.
Metro expansion programmes, rail tunnels cutting through mountain ranges, cross-border underground transport systems, and smart cities requiring resilient underground utility networks are all driving sustained, large-scale investment in tunnel construction across the region.
The Tunnel Construction segment at InnoTrans Asia reflects this momentum. It covers:
From metro expansion in Southeast Asia to rail tunnels through the Himalayas, from smart cities demanding resilient underground utility networks to urban mobility infrastructure threading beneath dense city centres, tunnel construction in APAC is one of the defining infrastructure stories of the decade.
InnoTrans Asia 2027 showcases technologies powering underground construction across the Asia Pacific. From excavation to operations, every phase of tunnel engineering is represented on the exhibition floor.
APAC governments are prioritising metro rail systems, underground transport corridors, and mountain railway infrastructure to overcome geographic constraints and urban congestion. Asia Pacific’s commitment to underground infrastructure is structural, not cyclical.
Several converging factors make underground infrastructure indispensable:
The Tunnel Construction segment at InnoTrans Asia is a commercial platform built for companies that want to sell into Asia Pacific’s underground infrastructure boom.
Target exhibitors include:
InnoTrans Asia places your tunnel construction business in front of the buyers, making procurement and partnership decisions for APAC’s major underground infrastructure projects.
The exhibition audience includes:
InnoTrans Asia is built to attract the specific decision-makers investing in underground infrastructure at scale across the Asia Pacific market, making it the most relevant platform for tunnel construction exhibitors in the region.
Visiting the Tunnel Construction segment offers industry professionals an efficient way to source suppliers, evaluate technologies, and benchmark underground engineering innovation against the region’s project pipeline.
Professionals who should register include:
InnoTrans Asia is a working event. Attendees come to source suppliers, evaluate technologies, benchmark solutions, and build the professional relationships that accelerate project delivery. The exhibition is structured to support:
Whether you are managing a metro tunnel construction programme, specifying TBM systems for a mountain rail corridor, or sourcing safety and monitoring technology for an urban underground project, InnoTrans Asia gives you access to the full supplier ecosystem in three focused days.
The tunnel construction industry in Asia Pacific is evolving rapidly.
Exhibitors and attendees at InnoTrans Asia 2027 will engage with the most significant technology and market trends shaping the next decade of underground infrastructure across the region.
The InnoTrans Asia conference programme runs alongside the exhibition floor, providing structured knowledge sessions on the most pressing challenges and opportunities in tunnel engineering and underground infrastructure across the Asia Pacific.
Sessions cover the full range of industry priorities, including:
The event is designed for senior infrastructure professionals, project directors, technical specialists, and policymakers. Sessions combine regional market intelligence with practical engineering insight, providing attendees with knowledge they can apply directly to active and pipeline underground infrastructure projects.
InnoTrans Asia 2027 is structured to facilitate meaningful business connections between tunnel construction suppliers and the infrastructure decision-makers investing in underground infrastructure across the Asia Pacific.
The event’s business matching programme connects exhibitors and attendees with pre-qualified counterparts based on project requirements, procurement timelines, and technology interests.
Key audience segments for business matching include:
Three days, 15,000+ attendees, and the most commercially active segment of Asia Pacific’s infrastructure market, InnoTrans Asia is where the conversations that drive underground infrastructure forward take place.
InnoTrans Asia is designed specifically for the Asia Pacific infrastructure market. Unlike global exhibitions that spread attention across multiple regions and sectors, InnoTrans Asia is focused exclusively on APAC, the world’s most active market for new transport infrastructure investment, and structured around the full transport technology ecosystem.
For tunnel construction businesses, this focus matters. Your buyers and partners are not distributed across multiple continents; they are concentrated in the fastest-growing infrastructure market on earth, and InnoTrans Asia is built to connect you with them directly.
The event positions tunnel construction as an integrated part of the broader transport infrastructure ecosystem, with direct connections to:
This multi-segment structure means that tunnel construction exhibitors at InnoTrans Asia are not operating in isolation. They are part of a connected, comprehensive transport technology ecosystem, which is how APAC infrastructure buyers think, plan, and procure.
Join us at the inaugural InnoTrans Asia and shape the future of mobility in the region
Tunnel Construction Asia is a dedicated exhibition segment within InnoTrans Asia 2027, the Asia Pacific transport technology and infrastructure event taking place at Singapore EXPO from 7 to 9 September 2027.
The segment brings together tunnel construction companies, TBM manufacturers, underground engineering firms, safety technology providers, and infrastructure consultants serving the Asia Pacific market. It is designed to connect tunnel construction technology suppliers directly with the infrastructure buyers, rail authorities, metro operators, and EPC contractors, driving underground infrastructure investment across the region.
InnoTrans Asia covers the full spectrum of tunnel engineering and underground construction technology, including:
Yes. TBM exhibition Asia is a core feature of InnoTrans Asia 2027. The event covers the full range of tunnel boring machine technologies, from earth pressure balance and slurry TBMs to hard rock machines and microtunnelling systems, alongside the broader ecosystem of underground construction machinery, excavation systems, and support technologies that modern tunnel construction depends on.
InnoTrans Asia brings TBM suppliers into direct commercial contact with the metro operators, rail contractors, and infrastructure authorities procuring tunnelling systems for APAC’s major underground projects.
InnoTrans Asia’s Tunnel Construction segment is the right platform for any business supplying technology, equipment, or services to the underground infrastructure market in the Asia Pacific. This includes:
Rapid urbanization, rising congestion, and limited land availability are accelerating underground infrastructure investment across the Asia Pacific.
Governments are expanding metro networks, high-speed rail, and smart city infrastructure, while tunnel construction is becoming essential in dense cities and challenging terrain. Climate resilience is also driving demand, making Asia Pacific the world’s largest and fastest-growing tunnel construction market.
Yes. InnoTrans Asia connects tunnel construction and underground infrastructure suppliers with metro authorities, rail operators, EPC contractors, engineering consultants, and government agencies across Asia Pacific.
Through its business matching programme, exhibitors can arrange pre-qualified meetings with procurement teams, infrastructure planners, and project contractors involved in major underground transport developments.
Registration for booth space is on a first-come-first-served basis, subject to availability.
