SECTION J ATTACHMENT.pdf

This is a Justification for Sole Source document ($15K-$350K) submitted by the Defense Logistics Agency Weapons Support at Puget Sound Naval Shipyard for the procurement of a Starrett model HB400 optical comparator.

The requirement is limited to a single source due to the specific characteristics and features of the Starrett HB400, which is one of only two optical comparator models qualified for the Puget Sound Naval Shipyard's calibration program. The HB400 is being procured because of its compact benchtop footprint (critical for limited space in the C/138 lab), optical edge detection, interchangeable lenses, maximum load capacity of 10 pounds, extended X-axis travel, dual mirror imaging capability, and vertically correct imaging in the 16-inch class. No other benchtop optical comparator with this combined feature set is available. The original manufacturer is Starrett, with the dealer and representative identified as PT Solutions (Jeremiah Hansen). The manufacturer's contact information includes Starrett's address at 2652 Merit Circle #103, Laguna Hills, CA 92653, and PT Solutions' address at 4453 S 134th Place, Tukwila, WA 98168. The item represents the minimum requirements of the government and requires no coordination or interfacing with existing lab equipment. The justification also notes this unit is one of two models within the qualified calibration program established at PSNS and specifies these are direct replacement parts/components for existing brand name equipment. The document is signed and certified as complete and correct by a Welding Engineering Technician, dated 5/20/25, with contracting officer approval dated 08/08/26.
