Tung Chat Engineering Company LIMITED

Tung Chat Engineering Company LIMITED, a foreign government entity based in Samut Prakan, Thailand, provides facility renovation, infrastructure maintenance, and construction services to the U.S. Department of the Navy as a prime contractor, with all twelve recent awards placed directly with the Navy's Chief of Naval Operations without set-aside designation.

Tung Chat is a Thailand-registered company delivering concrete facility work: ceramic tile and epoxy flooring installation, mechanical and electrical system maintenance, pipe replacement, HVAC exhaust hood projects, room renovation, gymnasium upgrades, and construction material supply for military infrastructure in the Asia-Pacific region. Representative work includes a $204.8 thousand renovation of an AAALAC preparation facility at a Veterinary Medicine Building (awarded September 2024, completed February 2025), a $196.6 thousand provision of construction materials for a boat house project at a Royal Thai Marine Corps camp (awarded August 2023, completed December 2023), and a $53.6 thousand gymnasium renovation in a library building (awarded September 2024, completed August 2025). Most recent awards, placed in May and September 2025 and May 2026, cover insulted wall work, exhaust hood installation, pipe replacement, and office renovation at the Armed Forces Radiobiology Research Institute in Thailand, with contract values under $13 thousand per order.

Customer concentration is highly concentrated: the Department of the Navy accounts for 100% of awards by count (10 awards) and 84% of combined potential value ($510 thousand), with the U.S. Agency for International Development Regional Development Mission for Asia holding the remaining two awards ($97 thousand combined). Work is performed entirely in Thailand to support U.S. military and development operations. Primary NAICS categories are Industrial Building Construction (8 awards) and Other Building Equipment Contractors (1 award), with PSC alignment centered on Architect and Engineering–Construction: Restoration of Real Property (7 awards) and Repair or Alteration of Other Administrative Facilities (2 awards).

Activity has accelerated in recent years: one award in 2020, one in 2023, two in 2024, five in 2025, and two in 2026 year-to-date. Combined federal contract potential across all twelve awards totals $607 thousand, with 100% of that amount already obligated. The vendor operates as a full-and-open prime with no IDVs, BPAs, or parent vehicles in the source data, and performs no subcontract work. Tung Chat's footprint is narrow and specialized — small-dollar, site-specific facility and infrastructure maintenance work at a single U.S. Navy installation complex in Thailand, with occasional supplementary orders from USAID's regional mission.
