River Cooperative substation 100 yards directly north east of the VT Hanlon substation.

The Contractor shall load, transport, and unload the material to the jobsite. The Contractor shall inspect the equipment and report any damages to the COR.

2. PROTECTION OF MATERIAL: Provide suitable indoor or warehouse storage for the following items: station batteries, battery chargers, and vertical switchboards. Provide protection against the elements after being removed from indoor storage and before installation, as directed by the manufacturer.

G. RIGHTS-OF-WAY:

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

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, since several areas of the transmission line have travel restricted areas. During the contract period, Western reserves the right to use Contractor-obtained access.

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. 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. Unauthorized excavation, dozing, blading shall immediately be repaired, or Western will have the damage repaired and back charge 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.

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.

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.

Until permanent power is available, provide 24-hours a day temporary power to the service building to serve all building loads including HVAC, lighting, and station battery system. Provide temporary heating prior to beginning finish work, sufficient to keep the interior of the building at a minimum of 70 degrees Fahrenheit for 24-hours a day, until permanent heating is available.

J. WATER CONSTRUCTION PURPOSES:

Furnish water for construction purposes. Make arrangements for obtaining the water, and provide for conveying the water to the points of use.

K. EXPLOSIVES AND BLASTING:

Explosives shall not be used.

L. SUBMITTALS:

1. GENERAL: The Contractor shall furnish submittals via email as specified in the Construction Standards and this Project Specification. Submittals via email shall be in standard PDF or Electronic CAD “*.dwg” (AutoCAD 2014) formats.
