About S-Tec System Co., LTD
S-Tec System Co., LTD, doing business as S-Tec System, is a South Korea-based for-profit facility services company that delivers house make-ready, warehouse support, security guard, and medical terminal cleaning services to U.S. government installations overseas as a prime contractor (97% of recent awards) on a full-and-open, non-set-aside basis. Headquartered in Gangnam District, Seoul, South Korea, S-Tec System has been registered with SAM since 2010 and competes exclusively through open competition; no SBA designations apply.
The vendor's federal footprint is concentrated geographically and functionally in South Korea, where it serves the Department of State's diplomatic and consular operations and the Department of Defense. Over the past five years, S-Tec System has received 35 federal awards totaling $9.1 million in combined potential value, with 22% of that value obligated to date. Activity accelerated sharply in 2024 and 2025, growing from one award in 2022 to sixteen in 2025. The work is characterized by low individual order values—most delivery orders fall between $10 thousand and $14 thousand—reflecting frequent task-order issuance against standing indefinite delivery vehicles rather than large single procurements.
The Department of State dominates S-Tec System's customer base, accounting for 94% of recent awards across two organizational units. The Bureau of Overseas Building Operations issued twenty-five awards (combined potential value $301 thousand) for house make-ready services—facility preparation, maintenance, and cleaning work supporting diplomatic housing and administrative facilities. The Bureau of East Asian and Pacific Affairs issued four awards (combined potential value $3.9 million), including a $1.84 million definitive contract awarded May 16, 2024, for warehouse support services at the U.S. Embassy in Seoul with an initial one-year base period and four one-year option periods running through May 15, 2027. The Department of the Army Medical Command awarded a $676 thousand security guard services contract to S-Tec System on July 15, 2025, for Brain D. Allgood Community Hospital in South Korea, running five years through July 14, 2030. The Department of the Air Force holds a secondary position with a $3.5 million single-award Blanket Purchase Agreement for medical terminal cleaning services through August 2025, against which two small task orders have been issued.
S-Tec System's primary vehicle position is an indefinite delivery contract (IDC 19KS7022D0003) valued at $2,057,009.71 held with the Department of State's Bureau of East Asian and Pacific Affairs and Bureau of Overseas Building Operations for make-ready services in South Korea through July 31, 2027. This vehicle has generated twenty-seven task orders totaling $324 thousand in combined potential value. The vendor also operates under the Air Force Blanket Purchase Agreement W90VN720A0006 ($3.5 million ceiling) with two task orders issued, and participates in an Operations and Maintenance Engineering Enhancement VII vehicle with one task order.
The vendor's capability portfolio is narrowly specialized: NAICS 332710 (Residential Remodelers) covers 28 awards focused on maintenance of family housing facilities; NAICS 561790 (All Other Support Services) covers four awards; and NAICS 561613 (Security Guards and Patrol Services) covers two awards including the Brain D. Allgood contract. There is no subcontract footprint of significance—S-Tec System holds 97% of awards as prime contractor and carries only one sub-award (a November 17, 2025 call under J & J Maintenance Inc. for O&M services). Two awards face recompete within the next twenty-four months with combined potential value of $1.9 million. S-Tec System's business model is built on maintaining standing relationships with State Department and DoD facility-management entities, leveraging low-touch delivery-order issuance against IDVs to capture frequent, small-value renewals for site-based services rather than pursuing competitive bidding for larger prime contracts outside South Korea.
