Location: Enbridge Pipeline: Wisconsin to Illinois
Services: geotechnical, drilling
We provided geotechnical engineering services for 133 miles of 42-inch diameter mainline pipeline from Delevan, Wisconsin to Streeter, Illinois and 20-inch pipeline to Manhattan, Illinois.
The Enbridge Southern Access/Southern Lights project includes design and construction of a new pipeline
running from Delevan, Wisconsin to Patoka, Illinois. The new pipeline is intended to accommodate growing production from the Alberta Oil Sands
and is part of a broader Enbridge strategy to provide greater access to new U.S. markets for Canadian crude oil supplies. Our drilling
, laboratory testing and engineering analysis
services were provided at 14 Horizontal Directional Drill
Our foundation recommendations for these sites were included in Enbridge’s reports addressing footing loads from equipment. Design and construction recommendations for the mainline included Enbriconsiderations, suitable trench backfill recommendations and temporary shoring recommendations. Laboratory testing was performed on the soil samples to estimate index properties of the soil.
Our team also completed 500 borings along the main pipeline route, as well as, a geotechnical assessment of property at the end of the pipeline for a proposed new tank farm in Patoka.
