138 kV Transmission Line Rebuild

Scope of Work
Cianbro is rebuilding 19 miles of 138 kV transmission line, including the removal of two circuits on existing lattice towers and the construction of two circuits with steel monopoles on foundations.
Project Details

Cianbro will:

  • Install and remove access/construction matting and erosion controls
  • Install 128 new steel monopole structures
  • Install 792,000 feet of new conductor
  • Remove 107 existing lattice towers
  • Remove 693,000 feet of conductor
Lean, Innovative and Unique Project Solutions

The schedule for this project extends over two years due to being broken into 6 separate segments. The terrain that the transmission line covers varies from flat agricultural fields to densely populated suburban neighborhoods and also includes an interstate crossing.

The project team is utilizing new, higher capacity rope pullers which improves the team's wire pulling efficiency and eliminates hardline pulls. The team is making additional efficiencies by using outside resources to spot steel which allows members of the team to be utilized for other tasks.
