The total estimated amount is $192,611.97. The Contractor shall deliver with NO DEVIATIONS on or before the specified delivery date after award. The requirement is sole sourced to Pama Incorporated (CAGE: 7BU28).

2. SUPPORTING DOCUMENTATION FOR SOLE SOURCE BASED ON

CONTRACTOR’S UNIQUE QUALIFICATIONS OR NATURE OF THE ACQUISITION

Pama is the Original Equipment Manufacturer (OEM) of the SU-23 and the SU-24 and have affirmed on 6 April 2022 that they are the only source authorized to provide the ball screw assemblies. Pama’s technicians have intimate knowledge of the machine components to ensure machine downtime will be at a minimum. Each head is very different and is built with the company’s own proprietary schematics and diagrams. Pama does not release this information and it is not possible for the heads to be designed, diagnosed, disassembled and repaired without it.

An outside company will not have any of the required proprietary information to complete proper procurement of the ball screw assemblies. Additionally, Pama does not allow use of authorized distributors.

Based on the above, Pama Incorporated is the only source that can satisfy this requirement.

3. MARKET SURVEY

Market research was conducted by contracting the OEM and internet searches. As a result, the Government did not identify any alternative options for this requirement.

4. ADDITIONAL FACTS

None.

5. APPROVALS:

I certify that the statements and information provided above, are complete and correct to the best of my knowledge. I understand that the processing of this justification precludes the use of full and open competition.
