Tunnel Engineering Consultancy
Tunnel Engineering Ltd offers specialist geotechnical and tunnel engineering consultancy services from concept design to construction and project completion. We work closely with clients to develop optimal engineering solutions for complex underground and infrastructure challenges.
We provide peer review of technical documentation at any stage of a project. This includes independent reviews of methodologies, designs, technical reports, temporary works, programme, and more.
With extensive industry experience, we support clients through the design and construction of underground structures, offering practical and innovative solutions grounded in technical expertise. Our team has worked across multiple sectors, including hydropower, railways, metros, roads, water, wastewater, power, and mining, delivering significant value through sound engineering, commercial insight, and robust project delivery.
