A new case history on GeoEngineers’ award-winning directional microtunnel design for the Tennessee Gas Pipeline Company, LLC, a Kinder Morgan Company, is now available. Jon Robison, PE recently presented the case history at the American Society of Civil Engineers (ASCE) pipelines conference in Portland, OR. The presentation and associated paper Innovative Directional Microtunnel Garners Success for Crucial Trenchless Crossing (PDF) discusses how the project team successfully used this approach at a difficult site crossing along Interstate 84 and US Highway 6 near Matamoras, Pennsylvania.
