SUMMARY OF WORK

Nenana VORTAC Vegetation Removal

March 8, 2021

1.0 GENERAL

FAA VORTAC equipment requirements include a ground level horizontal 1000 ft. radial clear zone. The Nenana VORTAC located on FAA property has had significant vegetation growth encroaching the 1000 ft. radial clear zone. As a mountaintop facility, there are trees located on the flat top and the sloped edges surrounding the antenna. Trees below the horizontal antenna base field of view do not affect signal radiation. Approximately 5 acres of trees and brush require removal. The remaining 1000 ft. zone is below line of site and does not affect the signal. The purpose of this project is to remove approximately 5 acres of vegetation from the areas designated on the attached map for the FAA VORTAC facility in Nenana, Alaska.

The selected Contractor shall furnish all labor, (specialized) equipment, materials, transportation and supervision of the work associated to complete all of the work. This includes, but is not limited to; identify the limits of the radial zone, identify the vegetation/trees within the specific zone and proceed to remove the vegetation/trees. Prior to project implementation, all working concepts and/or methods shall be reviewed by the FAA’s Contracting Officer’s Representative (COR).

The following items are a summary of the project and are provided solely for the purpose of describing the general nature of the work. The Contractor is responsible for accomplishing all items of work identified in the applicable drawings, specifications, and provisions of the contract:
