Grand Award – GeoEngineers, Inc., Springfield
Project: Dakota Access Pipeline Geotechnical & HDD Design
Client: Energy Transfer Partners, LP
GeoEngineers provided geotechnical and trenchless engineering services to support the successful completion of the highly publicized Energy Transfer Dakota Access Pipeline project. The state-of-the-art, 30-inch-diameter, 1,172-mile-long pipeline extends from North Dakota to Illinois. GeoEngineers performed geologic hazards route review; geotechnical explorations, laboratory testing and engineering design for 62 horizontal directional drills (HDDs), including major crossings of Lake Oahe, the Missouri and Mississippi Rivers among others; and geotechnical engineering and construction observation services at six oil storage tank facilities. Through the design process, GeoEngineers supported Energy Transfer’s permitting teams with significant technical involvement with regulatory staff. In construction, GeoEngineers provided engineering expertise in the field to document compliance with project specifications and permit requirements on the most scrutinized HDDs. GeoEngineers’ work helped Energy Transfer navigate a complicated permitting process and public perceptions, which, in turn, allowed Energy Transfer to move domestically produced crude oil to industry throughout the United States.
