In a world of increasing urbanisation with higher economic, social and environmental demands, the use of the underground space helps deliver efficient, safe and resilient solutions to the challenges faced by modern society. Underground space development is an important part of city planning and is included in the majority of existing urban plans. Efficient use of underground space promotes sustainable development, improves urban environment, preserves natural resources, and offers long-term economic benefits

Tunnels transform transportation networks by linking nations, uniting communities, and reducing travel time. Water and wastewater tunnels make modern hygiene and sanitation standards possible. Utility tunnels bring us our electricity, telephone, internet, and gas pipelines, enabling us to power our lives. Underground spaces contribute to our transit networks, our energy reserves, and our scientific research.

We provide comprehensive services for every aspect of the construction of tunnels and underground projects, including tunnel design, ground improvement, initial and final support, instrumentation and monitoring, tunnel systems, and ventilation/fire life safety aspects. Our experience encompasses all types of excavation methods including conventional tunnelling using drill and blast methods and road headers, cut-and-cover, New Austrian tunnelling/sequential excavation method, and full-face mechanised excavation using tunnel boring machines, pipe jacking and shaft-raising plant.
