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. WAPA 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.

H. ELECTRIC POWER FOR CONSTRUCTION PURPOSES:

Limited single-phase or three-phase power at approximately 120/240 volts nominal is available without charge from receptacles or panelboards located throughout the substation. If this power is not suitable for construction purposes, the contractor shall furnish his own power. Coordinate with the Contracting Officer’s Representative (COR) for establishing such service.

I. 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.

J. EXPLOSIVES AND BLASTING:

Prior to excavation, the Contractor shall examine the area and determine the location of buried utilities.

Utilities shall be identified with a marker denoting the type of service.

L. EMPLOYEE REQUIREMENTS:

In addition to the requirements listed in WAPA Construction Standard 1.4.3 all employees are restricted from wearing a headset, headphone, or other listening device, other than a hearing aid or instrument for the improvement of defective human hearing, hearing protection worn as the hazard exists, or for communication purposes while on a WAPA jobsite.

M. ELECTRICAL MINIMUM APPROACH DISTANCES:

In addition to the requirements listed in WAPA Construction Standard 1.4.9 equipment other than cranes and derricks, conductive objects, or personnel, shall not be brought closer to energized facilities than the electrical minimum approach distances established by OSHA 1926.958(b), “Materials, Handling, and Storage”. The less stringent equipment clearance distances established by OSHA 1926.960, “Working On or Near Exposed Energized Parts”, Table V-5 and Table V-6, may only be used after the Contractor has completed and submitted WAPA’s Electrical Clearance Variance form and has received the signed form in return from the COR.

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.
