H. GEOLOGIC INVESTIGATIONS:

The 8000-series 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. 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.

I. ELECTRIC POWER FOR CONSTRUCTION PURPOSES:

Electric power up to a maximum of approximately 5-kVA for construction purposes will be available without cost. Source of supply is located in the receptacles throughout the substation. Power made available by WAPA will be delivered as single-phase, 60 Hz, AC, at approximately 120-240 V.

Message from the Administrator

At Western Area Power Administration (WAPA), 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 WAPA. In performing work for WAPA, 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 WAPA is a safe place to work.
