DIVISION 1 – GENERAL REQUIREMENTS

A. CONTRACT REQUIREMENT:

Construct and complete Rapid City-Dry Creek 115-kV Transmission Line - Steel Pole Structure Foundations, in accordance with the Construction Contract (Standard Form 1442); the Contract Clauses; Western’s Construction Standards, including Standard 1 – General Requirements (September 2013), Standard 2 – Sitework (September 2013), Standard 3 – Concrete (September 2013), Standard 13 – Environmental Quality Protection (September 2013), Standard 15 – Drawings (September 2013); Standard Drawings; and these Project Specifications and Drawings.

If a conflict occurs between the project specifications and the construction standards, the project specifications shall govern. The project specifications and the Drawings are used to take exceptions or provide additions to the construction standards. Some paragraphs in the construction standards will not apply to this job.

Western’s construction standards, standard Drawings, and electrical equipment standards are available at http://www.wapa.gov/business/buys.htm.

Western project specifications and construction standards are explained in Standard 1 – General Requirements, Section 1.1.1 “Standards and Project Specifications”.

a. The electrical operation of the transmission lines are under the jurisdiction of Western’s

Watertown Operations Office. All outage requests by the Contractor shall be subject to the approval of the COR. Approval or denial of an individual outage request will be based on transmission system electrical loads, system operating configurations and weather conditions at the time the outage is scheduled to begin.

G. RIGHTS-OF-WAY:

1. GENERAL: Transmission line right-of-way is 80 feet wide. Western does not represent that the Contractor can gain access to every foundation 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 may have travel restricted areas. During the contract period, Western reserves the right to use Contractor-obtained access.

NOTE: The transmission line right-of-way between Structure Nos. 1/2 (Station 57+74) and 1/14 (Station 105+12) lies within the 100-year flood plain of Rapid Creek, and access can be difficult during flood conditions or periods of high runoff. See drawing RC-DRY T200.

2. 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 that is 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 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.

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 drawing RC-DRY 8000.

Samples and cores of recovered material were not retained. Additional geologic borings will not be allowed. 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 work site.

I. ELECTRIC POWER FOR CONSTRUCTION PURPOSES:

Make arrangements and provide all electric power for construction purposes. At contract completion, remove temporary electrical equipment.

J. WATER FOR 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 2010) formats. All submittals shall include the Western specification number, Western project title, and Bidding Schedule Contract Line Item Number (CLIN) and applicable division number. A cover transmittal letter in Microsoft Word or PDF format shall be included with each email.

2. APPROVAL TIME: Approval time for submittals shall be in accordance with the

“Commencement, Prosecution, and Completion of Work” paragraph.

3. TRANSMITTAL: The Contractor shall transmit submittals to the Construction Field Engineer.

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.
