Beginning at the Minnesota/Wisconsin state line, the Line 3 Segment 18 pipeline runs east to Enbridge’s Superior, WI, terminal. The 14-mile Segment 18 portion consists entirely of 36-inch-diameter spiral-welded pipe.
We provided construction surveying services for the pipeline, including conducting 4-way sweeps, drafting alignment sheets, and creating acquisition drawings and as-built alignment sheets. Additional surveying services included construction staking and pipeline weld as-built.
