Mill Creek Tower Erosion Repair

Milan, IL

Client: MidAmerican Energy Company

Designer: Missman Group

Contract Amount: T&M – Emergency Contract

Delivery Method: Design-Build

Summary: 

This project involved the design and installation of  an erosion control system to stabilize soil around a high voltage powerline tower near a creek. The creek’s rapid erosion was threatening to undermine the tower’s foundations. Our work included:

  • Sheet Pile Cell: Installation of a 72-foot diameter sheet pile cell using 25-foot long PS 27.5 steel sheet piling, centered around the tower.
  • Erosion Control: Replacement of vegetation within the cell with filter fabric and crushed stone.
  • Foundation Support: Reinforcement of the undermined foundation to ensure stability.

These measures were implemented to prevent further erosion and protect the tower’s integrity.
