Description

As published on SAM.gov.

In accordance with Department of Defense FAR Supplement (DFARS) Procedures, Guidance, and Information (PGI) 206.103-170(d), the Government is issuing this RFI announcement as part of its market research. This RFI announcement is intended to determine the availability and technical capability of businesses to provide the required supplies.

The Naval Surface Warfare Center, Crane Division (NSWC Crane) is seeking information for market research purposes for the procurement of the manufacture, testing, and delivery of the AN/SPS-49 Roll Ring Assembly, Part Number 82007601. AN/SPS-49 Roll Ring Assembly is utilized in the AN/SPS-49 Antenna and Pedestal system. All AN/SPS-49 Roll Ring Assembly manufactured, tested, and delivered shall meet the requirements of the below Drawings, which are available as controlled attachments to this notice:

  • Drawing 82007601 REV - ASSY, TOLL RING, 41 CH
  • Drawing 81006101 REV - ROLL-RING ASSEMBLY, SPECIFICATION FOR (AN/SPS-49)

NSWC Crane intends to solicit and award a contract on a sole source basis to Diamond-Roltran, LLC 59 Porter Rd., Littleton, MA 01460-1433. This procurement will be conducted on a sole source basis in accordance with the statutory authority 10 U.S.C. 3204 (a)(1) as implemented by FAR 6.103-1, only one responsible source and no other supply or services will satisfy agency requirements.

The basis for restricting competition is that as the Original Equipment Manufacturer (OEM), Diamond-Roltran, LLC is the only source capable due to its ownership of the propriety data, technology, and manufacturing processes of the Roll Ring Assembly to meet agency needs. The qualification of another source would be twenty-four (24) months of prototyping, testing, and production. Thus, duplicating costs to qualify another technology at both the contractor and Government sites. Based on the above herein, award to any other source would result in substantial duplication of costs to the Government that is not expected to be recovered through competition and there is risk of unacceptable delays in fulfilling the agency’s requirements.

The Government is seeking information from Contractors mitigating the sole-source basis cited above. All responsible sources may submit a capability statement which will be considered by the agency. However, a determination by the Government not to compete this proposed contract action based upon responses to this notice is solely within the discretion of the Government. Information received will normally be considered solely for the purpose of determining whether to conduct a competitive procurement. 

This requirement is a follow-on procurement to Contract No. N0016421DWP73, currently being fulfilled by Diamond-Roltran, LLC.

Contractors must be properly registered in the System for Award Management (SAM) and the Joint Certification Program (JCP) in order to receive the controlled attachments. Offerors may obtain information on SAM registration and annual confirmation requirements by calling 1-866-606-8220 or via the internet at https://www.sam.gov. Information about the JCP is at https://www.dla.mil/logistics-operations/services/joint-certification-program/.
