How we support your geotechnical and tunnel goals

We deliver best‑fit solutions tailored to each client’s needs. Our experience spans investigation, design, and construction services across diverse environments—from remote and challenging locations to major, densely populated urban centers—covering road and rail tunnels, as well as water conveyance systems. 

Supporting Clean Energy and Water Infrastructure 

We support public and private sector clients in advancing renewable energy and water infrastructure, including geothermal systems, hydropower, and utility networks. Our services extend across the full lifecycle, from geological investigations and environmental due diligence to system design and construction support. 

Advanced In‑House Laboratory and Field Services

Our geotechnical laboratory offers comprehensive testing services, including specialized testing for tunnelling using NATM, Cut‑and‑Cover, and TBM methodologies. We conduct detailed soil and rock testing to support informed decisions and the safe, efficient delivery of large‑scale transport and water infrastructure. 

Supporting Growth with Sustainable Solutions

We lead in underground engineering and brownfield redevelopment. Our approach promotes efficient land use, minimize environmental impact, and strengthen/ enhance long‑term Infra resilience across transport and water systems. 

Upgrading Aging Infrastructure

CDM Smith specializes in the assessment and rehabilitation of critical infrastructure across roads and water networks, enhancing safety, performance, and capacity. Through trenchless technologies and advanced tunnelling methods—including TBMs and micro‑TBMs—we help deliver resilient systems prepared for future demands. 

Featured geotechnical and tunnel projects 

Always looking forward, we prepare today for the problems we may face tomorrow, guiding our clients through uncertainty and forging a path towards a more promising future.
