Sun System Supply Co LTD

Sun System Supply Co LTD, a for-profit corporate entity based in Thailand, delivers construction, renovation, and facility improvement services to U.S. government agencies operating overseas as a prime contractor competing under full and open competition with no set-aside designations. The vendor operates from Samut Prakan, Thailand, and performs work at U.S. diplomatic and development facilities throughout Southeast Asia.

Sun System Supply Co LTD's customer base is concentrated in the Department of State's Bureau of Overseas Building Operations, which accounts for 6 of 8 awards and $257 thousand of the $342 thousand combined potential value across the vendor's recent footprint. The U.S. Agency for International Development accounts for the remaining two awards: $73 thousand for Bureau of Humanitarian Assistance and USAID/Burma DSU office renovations, and $13 thousand for work under USAID's Regional Development Mission for Asia. The top two rankings track identically — no divergence between award count and dollar concentration — indicating stable customer preference rather than a mix of high-volume small orders and isolated large deals.

Recent work illustrates the vendor's capability in building systems and accessibility improvements. Representative awards include a $91.3 thousand third-floor renovation at a State Department chancery facility (awarded August 5, 2026, completion scheduled November 29, 2026), a $31.4 thousand replacement of NOB and EOB knee gates at a U.S. government facility in Thailand (February 7, 2024), a $72.9 thousand renovation of the Bureau of Humanitarian Assistance and USAID/Burma DSU office (July 14, 2023), and a $49.4 thousand HVAC upgrade to the second floor of a main house (April 6, 2022). All work is located in Thailand. The vendor has no subcontract footprint and no parent vehicles or IDIQs in the source data.

Activity is sparse and episodic: one award in 2020 and 2022, three in 2023, two in 2024, and one in 2026. Combined potential value of $342 thousand has been fully obligated across the eight awards, with one award ($91.3 thousand) scheduled for completion within the next twenty-four months and therefore facing recompete risk. The vendor does not compete in set-asides and has not accessed government-wide vehicles or BPA arrangements; all work flows through direct purchase orders from overseas State Department and USAID missions.
