Bonneville Power Administration (BPA) has a need to replace old and worn spacer dampers along the 19-mile Hanford-Wautoma #1 and #2 transmission lines. The project will involve the activities of riding the transmission lines with carts and changing the spacers as the carts proceed. Carts and new spacers will be placed on the line using a helicopter. Contract construction crews will then access the carts to perform the work. Fly yards will be established to stage the carts and spacers for pick up and delivery by the helicopter. The majority of the work will be above ground with only minimal support vehicles being on the ground below the work areas. All vehicles will remain on existing access roads. The work will provide system reliability. All work will be in accordance with the National Electrical Safety Code and BPA standards.
