Large-diameter tunneling projects allow for the construction of new pipelines beneath roads, railroads, waterways, and other challenging topography. Tunnel construction is typically capital-intensive, involves critical assets, and has an element of risk not present in traditional installations. 

The Clean Water Professionals of Kentucky and Tennessee present a Coffee with Experts for insight on the characteristics of successful trenchless projects from the perspective of the owner, consultant, and contractor. We will explore various topics associated with tunneling to include construction technologies review, geotechnical exploration requirements, design considerations, contract document considerations that are necessary to improve constructability, mitigate risk, and other considerations as they pertain to large-diameter trenchless installations.
