About the company
Youngjin Construction Inc., a for-profit South Korea-based construction firm, operates as a prime contractor delivering facility construction, repair, and upgrade services to the U.S. Army Installation Management Command (IMCOM) across U.S. Forces Korea installations. The vendor competes on full-and-open basis with no set-aside designations across its 118 prime federal awards, all issued by Department of the Army and Department of the Air Force entities in the Pacific theater.
Youngjin Construction's capability portfolio centers on military base infrastructure and facility maintenance in South Korea: barracks renovation and repair, road and pavement resurfacing, storm drainage system replacement, underground water line installation, heating and HVAC equipment replacement, retaining wall and erosion control work, perimeter security improvements, and miscellaneous facility upgrades at U.S. military installations. Representative work includes a $3.1 million delivery order from IMCOM Korean Region to repair Barracks Building 823 at Camp Casey (awarded April 6, 2022), a $3.7 million delivery order for perimeter boundary wall replacement at Camp Walker (awarded February 8, 2022), a $2.2 million delivery order for general repair work across USFK facilities (awarded February 14, 2022), and a $1.6 million delivery order to replace underground water lines at Camp Casey (awarded March 15, 2022). More recent work includes a $196 thousand delivery order to construct a waiting area and break area at Gate 7, Camp Walker (awarded April 30, 2025), and multiple smaller repair orders in 2026 for roof replacement, sidewalk work, and parking space modification at Camp Carroll.
Customer concentration is extreme and geographic. The top two Army IMCOM regions account for 97 percent of awards: IMCOM Pacific Region holds 64 awards valued at $1.82 billion in combined potential value, and IMCOM Korean Region holds 32 awards valued at $278.8 million. The Department of the Air Force Pacific Air Forces issued 12 awards totaling $4.5 million. Work is performed exclusively at U.S. military installations in South Korea, including Camp Casey, Camp Carroll, Camp Walker, Camp Hovey, Camp Bonifas, and Camp Tango. Of the combined $2.1 billion in potential value across all awards, only $58.9 million (3 percent) has been obligated, indicating the portfolio is heavily weighted toward ceiling values on indefinite-delivery vehicles rather than firm task-order commitments.
Youngjin Construction's principal vehicle position rests on four large indefinite-delivery contracts: Indefinite Delivery Contract W91QVN18D0050 (28 task orders, $24.2 million combined potential value), W91QVN18D0070 (24 task orders, $8.1 million), W91QVN18D0090 (22 task orders, $5.8 million), and W91QVN18D0110 (15 task orders, $19 million). The most significant vehicle is the $245 million multiple-award indefinite-delivery contract awarded by IMCOM Pacific Region on October 5, 2023, with an ultimate completion date of October 4, 2028, which serves as the parent for delivery orders covering both new construction under $2 million and ongoing repair and maintenance work. A second $9.5 million single-award indefinite-delivery contract for asphalt concrete pavement work at U.S. Army Garrison Daegu was awarded April 15, 2025, through April 14, 2030.
Activity has declined markedly. The vendor averaged 23 awards per year in 2022, declining to 8 awards in 2024 and 6 in 2025, with only 3 awards issued in 2026 through July. Youngjin Construction operates as a 100 percent prime contractor with no subcontract footprint in the source data. The vendor has been registered in the System for Award Management since at least 2008. All work is performed firm-fixed-price in South Korea; no domestic or CONUS performance is present in the award history.
