138kV- Rated ā€“ Transmission Line Relocation

138kV- Rated ā€“ Transmission Line Relocation, Wausau, WI

U.S. Highway 51 & South 29 Line Relocation

A Client’sĀ 34.5KV distribution line needed to be relocated as a result of a Wisconsin Department of Transportation highway interchange project.

Incorporating a future upgrade to 138kV, Realtime engineered (5) new steel-pole structures to accommodate the newly constructed overpasses.

Project Scope:
Realtime performed the following tasks:

  • Preliminary and final design of the line alignment, structures, and foundations.
  • Coordination with the Wisconsin Department of Transportation and Client.
  • Steel-pole structure design and specifications.
  • Soils investigation specifications and subcontractor coordination.
  • Drilled-pier foundation design and construction specifications.
  • Line construction specification.
  • Construction documentation including PLS-CADD files.
  • Field support to construction contractors.
  • Final project close-out.

Design Challenges & Solutions:
Long transmission line spans and clearance requirements over new highway overpasses led to custom poles ranging in heights up to (115) feet.

Poor soil conditions resulted in deep, large-diameter drilled-pier foundations.
