SOLE SOURCE MEMO DFT (SIGNED)_REDACTED.pdf

This document is a Sole Source Procurement Authority letter from the Mississippi Department of Transportation (MDOT) dated September 24, 2025. The MDOT Materials Division is seeking to purchase a dynamic friction tester (DFT) from the Shima American Corporation for testing concrete and asphalt surfaces. The specific equipment is needed to perform friction testing as outlined in MDOT Special Provisions (907-416-4, 907-417-3, and 907-418-3), which require DFT testing to ensure minimum friction values after construction. The total cost of this machine will not exceed $55,000.00.

The procurement is unique because Nippo Sangyo is identified as the sole manufacturer of this specific piece of equipment, with Shima American Corporation being its exclusive distributor in the United States. The document suggests this is a direct purchase without a competitive bidding process due to the equipment's specialized nature and singular source of availability. The procurement is being initiated by the MDOT Materials Division, specifically recommended by the State Materials Engineer, and will support essential testing requirements for transportation infrastructure construction projects.
