S-Tec System Co., LTD

S-Tec System Co., LTD, doing business as S-Tec System, is a South Korea-based facility services company operating as a prime contractor on full-and-open, non-set-aside competition for the Department of State and Department of Defense at overseas locations, primarily Seoul, Korea. The vendor holds no SBA designations and has been registered with SAM since 2010, competing entirely outside set-aside categories.

S-Tec System delivers facility preparation, maintenance, and cleaning services to U.S. government installations overseas, including house make-ready (facility preparation, maintenance, and cleaning for diplomatic housing and administrative facilities), warehouse support, security guard services, and medical terminal cleaning. The vendor's recent federal footprint reflects a sharp uptick in task-order volume under standing IDIQs and definitive contracts. Representative work includes 27 delivery orders under the Department of State's Indefinite Delivery Contract 19KS7022D0003 (IDC, awarded August 1, 2022, ceiling $2,057,009.71, running through August 15, 2027) for house make-ready services ranging from $10,124 to $15,417 per order; a $1,843,433 definitive contract awarded May 16, 2024, by the Bureau of East Asian and Pacific Affairs for warehouse support services at the U.S. Embassy in Seoul for a five-year period (one base year plus four one-year options through May 15, 2029); and a $684,317 five-year security guard services contract awarded July 15, 2025, by the Defense Health Agency for Brain D. Allgood Community Hospital in South Korea through July 14, 2030. The vendor also holds purchase orders from the Bureau of Overseas Building Operations for concrete masonry unit wall repair ($49,579, awarded September 18, 2026, completion December 30, 2026) and cement roof tile replacement ($199,232, awarded August 18, 2026, completion December 30, 2026) at Yongsan Embassy Housing in Seoul.

Customer concentration is geographic and agency-heavy. The Department of State Bureau of Overseas Building Operations accounts for 27 awards (73% of recent award count) with combined potential value of $550 thousand, driven by routine task-order issuance under the standing IDC. The Bureau of East Asian and Pacific Affairs holds 4 awards valued at $3.9 million (42% of combined potential value) and includes both the warehouse support definitive contract and one house make-ready delivery order. The Defense Health Agency contributes the security guard contract at $684 thousand. The Air Force and Army Medical Command together account for $3.5 million and $676 thousand respectively. All work is performed in South Korea with no domestic footprint.

The IDC 19KS7022D0003 is the dominant vehicle, hosting 27 task orders totaling $324 thousand in combined potential value. S-Tec System also holds a position on a Blanket Purchase Agreement (W90VN720A0006) carrying 2 task orders valued at $11 thousand. The vendor's position on these vehicles is exclusive to South Korea operations supporting diplomatic and military facilities.

Award activity has grown substantially — one award in 2022, two in 2023, eleven in 2024, and sixteen in 2025 — with three awards recorded in 2026 as of mid-September. The combined potential value across all 37 prime and sub awards stands at $9.3 million, with $2.2 million obligated (24% of potential). The recompete cliff within the next twenty-four months involves only 2 awards with combined potential value of $249 thousand. The vendor's sub footprint is minimal: one sub award to J&J Maintenance Inc. for O&M services (November 17, 2025), representing 3% of total awards.

NAICS concentration reflects the facility services focus: Residential Remodelers (NAICS 236118) dominates 30 awards, with All Other Support Services, Security Guards and Patrol Services, and Facilities Support Services making up the remainder. PSC coding tracks similarly, with Maintenance Of Family Housing Facilities (Z1FA) covering 30 awards and specialized medical and housekeeping-guard PSCs accounting for the balance.
