About Tongzhou Construction General Contracting Group Co.,Ltd.
Tongzhou Construction General Contracting Group Co., Ltd., a Chinese for-profit limited liability company headquartered in Nantong, Jiangsu Province, provides facility maintenance, construction, and renovation services to the U.S. Department of State as a prime contractor exclusively — all 66 awards in its federal footprint are primes with no subcontract activity. The vendor competes full-and-open (no set-aside designations across its entire portfolio) and operates entirely overseas, performing all work at U.S. diplomatic facilities in China.
The vendor's customer base is heavily concentrated within the Department of State. The Bureau of Overseas Building Operations accounts for 50 of 66 awards and $3.6 million of $4.1 million in combined potential value (88% of the portfolio). The Bureau of East Asian and Pacific Affairs contributes 11 awards worth $382 thousand, with the Bureau of Consular Affairs, Bureau of Administration, and the Department of Commerce Office of Inspector General each placing single or small handfuls of orders totaling $73 thousand combined.
Tongzhou Construction's capability portfolio centers on facility maintenance, repairs, and construction services specific to embassy and diplomatic compound infrastructure. Representative work includes a $73 thousand firm fixed-price purchase order (awarded April 9, 2026, completing September 30, 2026) for roof safety facilities improvement; a $105.6 thousand purchase order (July 2, 2024) for renovation and repair of residential apartments; a $116.3 thousand purchase order (July 2, 2024) for PCP 16F ADA improvements; and a $92.5 thousand order (June 30, 2024) for carpentry repair at residence facilities. The work spans HVAC and building automation system repairs, ADA compliance upgrades, electrical infrastructure upgrades, interior wall refreshing, concrete loading dock construction, furniture installation, roof guardrail manufacture and installation, expansion joint leak repairs, and walkway repaving — all supporting ongoing operational and compliance needs at U.S. diplomatic properties.
Award activity has remained modest and episodic over the past five years, with two awards in 2022, one in 2023, five in 2024, six in 2025, and two in 2026. Only one award carries an ultimate completion date within the next twenty-four months ($73 thousand). The vendor has maintained this service relationship with State Department OBO since at least 2014 and operates almost entirely as a sole local contractor in China, with no domestic U.S. presence or subcontractor network visible in the award record.
