Seong Bo Const.ind.co.,Ltd.

Seong Bo Const.ind.co.,Ltd. Usfk DIV Division, headquartered in Seoul, South Korea, is a for-profit South Korean construction and facilities maintenance company that operates exclusively as a prime contractor on federal construction and infrastructure projects at U.S. military installations throughout South Korea, competing in full-and-open procurements with no set-aside designations across its portfolio.

The vendor's federal footprint is heavily concentrated in the Department of the Army, particularly through the Army Corps of Engineers Engineering District Far East (352 awards, $428.4 billion combined potential value) and Army Installation Management Command regional offices. The Army Corps of Engineers dominates the customer concentration—97 percent of the 807 awards in the source data are concentrated within the top five Army customers, with the Engineering District Far East alone accounting for 44 percent of all awards and 78 percent of combined potential value. Seong Bo's customer concentration reflects a near-monolithic posture: the Department of the Army accounts for approximately 99 percent of combined potential value across all awards. The remaining eight percent of awards, by count, split across the Department of the Air Force Pacific Air Forces (14 awards, $10.6 million potential value) and smaller Army subcomponents.

Seong Bo's capability portfolio centers on heavy and civil engineering construction (308 awards) and commercial and institutional building construction (210 awards) in the South Korean operating environment. Concrete work spans HVAC system replacement and repair, electrical infrastructure upgrades, airfield lighting installation, pavement resurfacing, building renovation, generator replacement, utility system repairs, emergency backup generator repairs, water fire suppression system restoration, heating system replacement, lift station repair, cooling system repair, drainage system remediation, and facility modernization across Camp Carroll, Camp Casey, Camp Hovey, Osan Air Base, Kunsan Air Base, and United States Army Garrison Humphreys. Representative delivery orders include a $34.3 million firm fixed-price definitive contract (awarded August 2, 2024) for construction of an unmanned aerial vehicle hangar and fire pump room drain line connection at USAG Humphreys with completion scheduled for January 2, 2028; a $6.7 million delivery order (awarded September 25, 2025) for HVAC system replacement at the Communications Center (Building P-2200) at USAG Humphreys, completing January 3, 2028; a $3.9 million delivery order (awarded September 15, 2025) for emergency backup generator repairs at Osan Air Base, completing November 30, 2027; and a $1.9 million delivery order (awarded September 30, 2025) for repair of Hovey Chapel at Camp Hovey, completing July 21, 2026.

Seong Bo holds four parent indefinite delivery contracts anchoring most of its task-order work. The largest is a $400 million multiple-award design-build IDIQ with the Department of the Army Installation Management Command through June 20, 2029 (funded through ENDIST Far East), which carries a $3.5 million minimum guarantee and covers comprehensive design-build construction services including facility repairs, upgrades, and new construction across the USFK footprint. A $245 million multiple-award general construction, repair, and upgrade IDC with the Department of Defense Pacific Region (effective through October 4, 2028) operates under the General Construction by OMA parent vehicle and facilitates rapid task order issuance for projects under $2 million—153 of the vendor's 807 awards are traced to the parent Indefinite Delivery Contract DACA8198D0022, indicating high-volume task-order activity under that vehicle. Three additional large Army Corps of Engineers IDIQs (W912UM09D0040 with $43.42 billion potential value at 107 task orders; W912UM12D0036 with $8.05 billion potential value at 72 task orders; W912UM07D0005 with $15.45 billion potential value at 64 task orders) complete Seong Bo's major vehicle portfolio. All delivery orders are firm fixed-price, performed in South Korea, and awarded without set-aside designation, reflecting the contractor's competitive standing in open competition for military construction work.

Activity has declined from peak years. Seong Bo recorded one award in 2026 (through April 9), eleven in 2025, twenty-two in 2024, and thirty-one in 2023, against a single award in 2022 and an earlier data point in 1993. Ten awards with combined potential value of $55.1 million face ultimate completion within the next twenty-four months, representing recompete exposure for the vendor. The source data reflects 807 total prime awards with $546.7 billion combined potential value; however, obligated dollars stand at only $361.2 million (less than 0.1 percent of ceiling value), a signal that many awards carry placeholder ceilings characteristic of indefinite delivery vehicles. Seong Bo operates exclusively as a prime contractor with no subcontract footprint recorded in the source data, and maintains no secondary business development relationships with U.S. prime contractors.
