Market Survey: UPP VOR Tree Trimming Services

Summary (Newest Update)

Background The Federal Aviation Administration (FAA), specifically the Western Service Area, Northwest Mountain Region, is conducting a market survey to identify capable sources for tree trimming services at the Upolu VORTAC (UPP VOR) site in Kona, Hawaii. The primary goal of this contract is to maintain the operational integrity of the VOR antenna by preventing interference from surrounding vegetation. The project involves trimming trees and removing obstructions that could affect the radiated signal from the antenna, particularly during critical periods such as the mating season of the Hawaiian Hawks. Work Details The contractor shall provide all necessary labor, materials, equipment, transportation, and services to complete the following tasks: 1. Cut, trim, and mulch shrubs, trees, grass, and other vegetation within a 350-foot radius centered on the VOR antennas and rotate as necessary around the antenna. 2. Mow and/or poison all vegetation on the entire counterpoise area. 3. Trim all trees, shrubs, and vegetation located below the counterpoise to at least six feet below the surface area (elevation 1765 feet) of the antenna counterpoise to ensure they are below the antenna line of sight. 4. Cut down, chip, and spread all trees and vegetation within this area on FAA property. 5. For trees outside FAA property, top them at least six feet below the surface area (elevation 1756 feet) of the antenna counterpoise and remove them. The contractor must also comply with FAA regulations to avoid interference with VOR operations and ensure minimal disruption to adjacent properties. Place of Performance Upolu VORTAC (UPP VOR), Upolu, Kona, Hawaii.
