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 expertise provides support across an entire project, from feasibility, to design, to construction management, to testing and commissioning. We also provide condition assessments, rehabilitation, re-purposing, and upgrading of tunnels and underground transportation facilities.
Tunnels begin with ground investigation, because accurate surveys are the best way to prevent surprises and delays further down the road. Our geotechnical experts have dedicated years not only to the practice, but also to research in order to continuously build upon our understanding of ground behavior during excavation. The result is an unparalleled breadth of acumen that continues to improve our ability to construct underground facilities without disturbing existing facilities and utilities, to ensure that our work doesn’t impact the surrounding area.
