The Badger Coulee 345 kV Transmission Line is a 180-mile, multi-benefit project that improves electric system reliability and expands infrastructure to support public policy for greater use of renewables. The line’s tubular steel structures were supported on several different foundation types, mainly reinforced drilled concrete piers, and direct embed foundations. However, in some of the Coulee regions in the Northwest portion of the project, micropile foundations were utilized. In total, there were over 1,100 foundations installed. ECI’s Survey Department supported the Badger-Coulee build by performing land net ties, easement exhibits for 600 properties, permanent access easements, and real estate-construction-condemnation support. By utilizing years of experience in surveying high voltage transmission lines, and an in-depth understanding of power line design and construction requirements, ECI’s survey crews were able to provide engineering support for structure location modification, road engineering, locating overhead and underground conflicts, right-of-way tree clearing, structure and work area staking for construction.

Work performed included:

• Parcel boundary identification and easement acquisition.
• Locating underground and aerial conflicts.
• Exhibit preparations for 600 properties.
• Road & access design.
• Staking for tree clearing of the transmission corridor.
• Staking of over 1,100 structures, work areas and construction pads.
• Engineering & construction Support/on-call services.

• Key Facts and Highlights:
  • Provided land net ties, easements and exhibits for 600 properties.
  • Conducted site surveys and effective construction staking.
  • Identified and notified crews of unforeseen construction obstacles.
  • Provided staking and foundation verification for QA/QC.
    Included MSHA and OSHA 30 trained crews.
