4. AUTHORITY CITED: FAR 13.106-1(b), Soliciting from a single source.

5. REASON FOR AUTHORITY CITED:

a. BACKGROUND: The components identified in this justification are required for the complete installation and functionality of the controls for the Lower Granite Wastewater Treatment controls. The components will be installed by the construction contractor. Allen Bradley ControlLogix PLC equipment is required for the control of and human interface with the Lower Granite electrical distribution systems. The equipment contains intellectual property protected by copyrights, patents and similar laws. The hardware and software are functionally linked and legally protected from copying. Allen-Bradley ControlLogix PLCs are currently in use at Lower Granite Dam and are successfully utilized in the facility’s SCADA and user interface systems. The remaining components must be compatible and able to interface directly with the existing control systems.

b. JUSTIFICATION: If the brand specific equipment is not purchased, significant negative risks would be introduced to the operation and maintenance of the Lower Granite electrical distribution system.

Non-compatibility of new PLC and SCADA equipment has the potential for failures resulting in loss of power and/or control to the wastewater system.

6. CONTRACT SPECIALIST: I certify that the information supporting this single source determination is accurate and complete to the best of my knowledge based on the supporting data provided by technical or requirements personnel.

Elaine Vandiver Contract Specialist

7. DETERMINATION: I hereby determine the circumstances of this contract action deem only one source available for the items described above to meet the Government’s need.
