E. CONSTRUCTION PROGRAM:

1. SUBMITTAL TIME: Submit a Construction Program to the COR within 15-calendar days after date of Notice to Proceed.

F. MATERIAL: Furnish all material for completing the work.

G. RIGHTS-OF-WAY:

1. GENERAL: Transmission line right-of-way is 40-feet-wide. Western does not represent that the Contractor can gain access to every structure site or travel continuously along the transmission line. The transmission line right-of-way is located adjacent to and on the northerly side of the U.S. Highway 26 right-of-way between Structures 13/12 and 15/5. Between Structures 15/6 and 20/5 the transmission line right-of-way is located adjacent to and on the southerly side of the Burlington Northern Santa Fe Railroad right-of-way.

Orient construction methods and equipment to utilize Government-furnished rights-of-way, or obtain additional temporary access without additional cost to Western. Any additional temporary access acquired by the Contractor shall have prior COR approval. During the contract period, Western reserves the right to use Contractor-obtained access.

Western is to provide railroad and highway crossing permits for the span between Structures 15/5 and 15/6 crossing these entities. Additional permits, if needed, shall be obtained by the Contractor at no additional expense to Western.

2. ACCESS EASEMENTS: Western has 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.

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. Excavation, dozing, and blading for ease of travel may only be performed after field review and approval by the COR. Unauthorized excavation, dozing, blading shall immediately be repaired, or Western will have the damage repaired and backcharge the Contractor for all costs involved.

b. Ease of Travel and Crane Landings: COR approved 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.

H. GEOLOGIC INVESTIGATIONS:

Geologic logs of subsurface explorations included in the “Drawings” Division constitute the information and records of geologic investigations for the work. Locations of subsurface investigations are shown on the drawings.

Samples and cores of recovered material were not retained. Bidders shall obtain their own samples and perform tests on the material to evaluate properties, which they believe to be significant.

Western does not guarantee that the geologic information and records show the conditions that will be encountered in performing the work, but only that the geologic information and records show conditions encountered at the particular point and time the information and records were obtained.

The geologic information may not indicate variations, such as those caused by seasonal fluctuations in rainfall and other factors, which may affect the water level. The Contractor shall determine the nature of material to be excavated, the difficulties of making and maintaining required excavations, and doing other work affected by geology and ground water elevations at the worksite.

I. ELECTRIC POWER FOR CONSTRUCTION PURPOSES:

Make arrangements and provide all electric power for construction purposes. Provide necessary transmission lines, distribution circuits, transformers, and other electrical equipment for distributing the power to the places of use. At contract completion, remove temporary electrical equipment and distribution lines.

Message from the Administrator

At Western, we show our commitment to safety every day through the actions we take, the training we offer and the work conditions we provide. We expect the same commitment to safety from each of our contractors who provide products or services to Western. In performing work for Western, all contractors must make the right decisions to ensure that the work environment is as safe as possible.

Our safety program is based on four points:

Safety procedures or common sense must be applied by each

Federal and contract employee. Safety should not be set aside to meet a project schedule or for personal convenience.

Employees and contractors must believe that they have the right and the responsibility to identify and take action to reduce, if not eliminate, hazardous work environments and hazardous work practices.

Managers and supervisors must lead by example and execute their responsibility to ensure each job is accomplished in a safe and healthy way.

Safety is a personal responsibility. Each individual makes the decision on what action to take to accomplish a task.

By integrating these principles into every task we take, together we can ensure Western is a safe place to work.
