Raising Transmission Line Steel Towers

Recently, ITC needed to raise 25 steel lattice towers by 10 or 20 feet each to enable the line to operate at its design rating. This paper will communicate the methodology and cost considerations involved in raising existing lattice towers vs. constructing new structures. It will also cover the project's critical path items, and potential improvements. By the end of the paper, readers will learn: Why did we need to raise steel lattice towers? How did we raise the steel lattice towers during construction? What were the key steps that made the project a success?
