Project Detail

345 kV Structure Change-Outs

Withheld Upon Owner Request

This was Cianbro's first Energized Structure Change-Out project. A full scale training mock-up was constructed at our training facility for team members to practice and fine tune safe "hot stick" methods. 

Scope of Work

Cianbro replaced four energized 345 kV Wood H-Frame Tanget Structures located in three different towns and 75 miles apart.

Project Details

For each H-Frame Tanget Structure Cianbro performed the following:

  • Mobilized tracked equipment to and from the structure locations
  • Spotted, excavated, set and backfilled new poles and demolished the old poles
  • Framed new structures and demolished the old structures
  • Transferred energized conductors utilizing "hot stick" procedures

Lean, Innovative, and Unique Project Solutions

Cianbro team members completed the energized structure change-outs during the coldest and shortest days in December.
