Brand Name Justification

Description of the action being approved: This justification documents the basis for issuing a firm-fixed price purchase order conducted under the procedures identified in FAR Part 13.5, Simplified Acquisition Procedures for Certain Commercial Products and Services, and the requirement will also be brand name or equal as identified in FAR Part 52.211-6, Brand Name or Equal.

Description of the supplies or services required to meet the agency’s needs: This action is a firm-fixed price requirement for Team Corporation, Mark VII Air Modulator System, Part No.

3102700. The modulator system includes Mark II Air Modulator, Manifold and accumulators, Team V-140 slave valve, Team V-20 voice coil pilot valve, Team 2208-T valve driver and 10-meter cables, Team 1510-F hydraulic sequencing control with 10-meter cables.

Identification of Brand Name Justification:

This is a Brand Name Justification.

Supporting Rationale:

A total of 23 of the Team Corp Mark VI and Mark VII acoustic modulators are used in the NASA Reverberant Acoustic Test Facility to make the facility the most powerful reverberant chamber in the world. The Team Corp. MK VII modulator is uniquely qualified for use in the RATF facility due to the following performance characteristics: 200,000 Acoustic Watts and frequency content of the acoustic noise output up to 10,000 Hz. This modulator is being ordered as a critical spare to ensure the facility can meet the correct power levels should one of the existing modulator systems fail. No other supplier capable of producing the exact same results is currently known to exist. For an alternative manufacturer be selected they would first have to design, qualify, produce, and commission the new modulator systems into the existing RATF hydraulic, nitrogen, and Acoustic Control Systems. The schedule for this effort would delay the availability of a spare modulator by a minimum of two years.

Determination that the anticipated cost to the Government will be fair and reasonable:

A fair and reasonable price determination will be conducted upon award in accordance with the

FAR.

A statement of the actions, if any, the agency may take to remove or overcome any barriers that led to the restricted consideration before any subsequent acquisition for the supplies or services is made:

The CO will continue to examine the market in the future for alternative solutions or new sources before executing any subsequent acquisitions for the same requirements.
