Jeong David

Jeong David, a sole proprietor based in North Reading, Massachusetts, delivers engineering consulting services for federal railroad track system safety research as a prime contractor on full-and-open purchase orders. The vendor is a self-certified small disadvantaged business and minority-owned (Asian-Pacific American owned) enterprise competing without set-aside designations.

Jeong David's entire federal footprint consists of three prime purchase orders with the Department of Transportation, specifically the Immediate Office of the Secretary of Transportation and the Volpe National Transportation Systems Center, spanning track safety research consulting work for the Federal Railroad Administration's Track Safety Research Program. The vendor's capability work is narrowly specialized: engineering consulting on rail integrity, track buckling, rail longitudinal force management, rail breaks, rolling contact fatigue, and Rail Neutral Temperature monitoring integration into FRA software environments (CWR-Safe and RNT-Restore). The three awards total $435 thousand in combined potential value, with $279 thousand obligated to date (64% of potential). The oldest award, a $150,540 firm fixed-price contract issued June 1, 2022, covered a base period through May 1, 2023, with an optional year exercised through May 4, 2024. A second $50,180 purchase order followed May 1, 2024, covering engineering consulting on railway track system safety through April 30, 2025. The most recent award, issued August 12, 2026, carries a $234 thousand ceiling and extends through August 11, 2029, requiring eight annual one-hour recorded consultations and four quarterly meetings per year during the base and two option periods; the solicitation (RFQ 6913G626Q300043) was posted July 22, 2026, and the award was made sole source under FAR Parts 12 and 13. All three contracts specify North Reading or Cambridge, Massachusetts, as the place of performance. The vendor does not subcontract and has not served other federal agencies or secured parent contract vehicles. Activity is minimal and episodic — one award every two years — with no growth trajectory visible in the source data.
