Underground Engineering Services
A Core Strength
Underground engineering, including design and construction of new facilities and
repair of existing facilities, requires in-depth, specialized knowledge and years of
experience to deliver successful projects.
Underground engineering continues to be one of NTH Consultants’ core strengths.
NTH professionals have designed tunnels and other underground projects, provided
field engineering during construction, investigated failures of underground facilities
both during and after construction, and repaired damaged facilities.
Over the past 38 years, we have worked on hundreds of underground projects
throughout North America. Much of our early work focused on helping contractors
deal with difficult ground conditions and failures during construction. This experience
has provided us with a greater understanding of how soils, rock and groundwater
behave when they are encountered in a tunnel or a deep excavation. In recent years,
we have worked with property owners, either designing new underground facilities or
repairing their existing infrastructure. Regardless of the client or the project stage, the
key to a successful project has always been, and will continue to be, constructability.
NTH knows what must be done to assure a constructible project.
