1. POINTS-OF-DELIVERY: With the exception of the power circuit breakers, material furnished by Western will be delivered to the warehouse at Western’s Tucson Substation, as shown on Drawing TUC 0015.

The power circuit breakers are stored at Coolidge Substation, located at 2288 N. Arizona Boulevard, Coolidge, AZ 85228.

The Contractor is responsible for loading, transporting, and unloading all Government-furnished material from its storage location to the worksite.

The Contractor shall be responsible for storing and safeguarding all material after receipt from the Government. The Contractor shall co-ordinate with AZDOT (the County’s transportation department, or applicable transportation agency) for any special loading and transportation permits during construction. The Contractor shall relocate all spare parts and unused material back to Western’s Warehouse, located at 615 S. 43rd Avenue, Phoenix, Arizona 85009, prior to the contract completion date.

During storage, the Contractor shall prevent ground or surface water contact by placing steel and aluminum on timber blocking.

G. RIGHTS-OF-WAY

1. GENERAL: Contact Western for the substation line right-of-way dimensions and physical restrictions. Orient construction methods and equipment to utilize Government-furnished rights-of-way, or obtain additional temporary access or any required permits without additional cost to the Western. During the contract period, Western reserves the right to use Contractor obtained access or any additional Environmental clearance needed during the performance period to complete the construction contract.

Any additional temporary access acquired by the Contractor shall have prior COR approval, since several areas of the transmission line have travel restricted areas. If additional access to the transmission line is needed, the Contractor shall be responsible for contacting the landowner to obtain permission to traverse their private road. The Contractor shall obtain a signed agreement from the landowner, granting permission to use their road for the duration of the project. Permission must be obtained, and the required agreements forwarded to the COR, prior to the work commencing on-site.

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, or 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 constitute the information and records of geologic investigations for the work. Locations of subsurface investigations are shown on Drawings.

Reference Geotechnical Engineering Report No. 65125300, dated December 13, 2012, prepared by Terracon Consultants, Inc.

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 the 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

Provide all electric power for construction purposes. Provide necessary transmission lines, distribution circuits, transformers, and other electrical equipment including circuit breakers 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 temporary power to the service building to serve all building loads, including heating and air conditioning (HVAC), lighting, and station battery system.

Provide temporary HVAC prior to beginning finish work, sufficient to keep the interior of the building between 70-80-degrees-Fahrenheit for 24-hours-a-day, until permanent HVAC is available.

J. WATER FOR CONSTRUCTION PURPOSES

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

K. EXPLOSIVES AND BLASTING

Explosives shall not be used.

L. SUBMITTALS

1. GENERAL: Submittals must be provided in accordance with the Construction Standards and Project Specifications. The Contractor shall furnish submittals electronically (i.e. e-mail), unless otherwise specified by the COR. Submittals shall be sent to: DSW-G5600-CS@wapa.gov in standard PDF or electronic CAD “*.dwg” (AutoCAD 2010) formats. All submittals shall include the project number, project title, Contractor’s transmittal/submittal number, Western’s standard reference (CLIN), and corresponding item number. Refer to the Submittal Log for the list of required submittals.
