Tunnelling and underground engineering provide economically viable and environmentally sound solutions for major transport infrastructure projects around the world, including highways, mass rapid transit systems and railways.
Rendel has extensive experience in the design and engineering of tunnelling systems which, combined with our knowledge in underground engineering, means we can provide a comprehensive service in the provision of new infrastructure. We are similarly able to assess operation, maintenance and rehabilitation requirements.
Tunnelling and underground engineering draws on a wide range of disciplines including construction planning, geotechnical, structural, mechanical and electrical engineering. Rendel provides skills and resources in all these areas in support of underground projects worldwide.
