1. GENERAL: Transmission line right-of-way is 125-feet-wide. WAPA does not represent that the Contractor can gain access to every structure site or travel continuously along the transmission line. NRPPD easement is 30-feet-wide.

Orient construction methods and equipment to utilize Government-furnished rights-of-way, or obtain additional temporary access without additional cost to WAPA. Any additional temporary access acquired by the Contractor shall be submitted to the COR 60-days prior to use for environmental review and approval, since several areas of the transmission line have travel restricted areas. During the contract period, WAPA reserves the right to use Contractor-obtained access.

The Contractor is responsible for obtaining staging, storage areas and pulling sites. Provide COR with landowner agreements.

2. ACCESS EASEMENTS:

a. WAPA has not acquired access easements from existing public roads to the transmission line, and some off right-of-way access along the transmission line. This off right-of-way access route is to provide access to the transmission line structure sites not accessible by traveling the transmission line.

b. The Contractor, at no cost to the Government, is responsible for working directly with the landowner to obtain a temporary easement/agreement to utilize, improve, or create roads not shown on project drawings. Each easement/agreement should specifically detail the reclamation to be completed after use. Upon obtaining this easement the Contractor shall send a copy of the easement, photos and videos of the initial condition to the COR.

3. WORK ON THE RIGHT-OF-WAY:

a. General: Perform work on the rights-of-way necessary for access to or along the transmission line. Only that excavation, dozing, or blading absolutely necessary will be allowed. Excavation, dozing, and blading for ease of travel may only be performed after field review and approval by the COR in accordance with Division 13. Unauthorized excavation, dozing, blading shall immediately be repaired, or WAPA will have the damage repaired and backcharge the Contractor for all costs involved.

b. Ease of Travel and Crane Landings: Excavation, dozing, or blading done for ease of travel on any easement or for crane landings shall be restored to the original contour of the land and shall be compacted to a dry density not less than the natural in-place dry density of the surrounding earth. The use of water may be required to obtain the required density. Topsoil shall be stockpiled and spread on cuts prior to completion of work.
