Construction Process
Rebuilding an electric transmission line involves a variety of activities set out in phases. Below are sample descriptions and photos; actual construction sequencing, methods, and materials will vary.
1. Site Preparation:
The first phase of site preparation and construction is tree and brush removal. Vegetation maintenance allows construction crews to build access roads and remove trees in danger of falling into transmission lines.
2. Environmental Controls:
Next, environmental controls would be installed to mitigate construction impacts to the area. These can include matting, silt fences, and concrete washout structures and containers, among others.
3. Transmission Line Rebuilding:
The next phase would be transmission line rebuilding, where foundations are poured, structures are spotted and erected, fiber optic cable is installed, and new wire is strung and energized. Old structures will be removed from the right-of-way. This work would be done with a variety of equipment, including cranes and other heavy equipment.
4. Restoration:
The final phase of construction is ground surface restoration, in which the construction area is restored to its pre-construction condition (unless otherwise specified in regulatory requirements or landowner agreements).
