Sunglim Engineering & Construction Co., LTD

Sunglim Engineering & Construction Co., LTD, operating through its Sunglim E&C Co., LTD division as General Construction, is a South Korea-based construction and facilities services prime contractor that delivers infrastructure repair, building renovation, mechanical systems work, and facilities maintenance services to Department of Defense agencies at U.S. military installations across South Korea as a wholly owned subsidiary of Sunglim General Construction C. The vendor competes full-and-open in the federal market without set-aside designations, and has accumulated 1,039 prime awards with combined potential value of $158.58 billion since 2009.

Customer concentration is extreme and geographically focused. The Department of the Army Corps of Engineers Engineering District Far East (ENDIST Far East) dominates both volume and dollars, accounting for 429 awards (41% of total) with $155.54 billion combined potential value (98% of all dollars). The next three customers account for 579 awards but only $3.2 billion in potential value: the Department of the Army Installation Management Command Pacific Region (375 awards, $2.32 billion); the Department of the Army Installation Management Command Korean Region (102 awards, $601.3 million); and the Department of the Air Force Pacific Air Forces (83 awards, $74.5 million). The vendor has served 20 distinct customer agencies, though the top five account for 97% of recent awards. Sunglim's work is overwhelmingly concentrated in commercial and institutional building construction (531 awards) and other heavy and civil engineering construction (303 awards), with primary service lines in maintenance of office buildings, repair and alteration of office buildings, and miscellaneous building repair.

The vendor's footprint rests on seven active indefinite delivery contracts with aggregate ceiling value of approximately $1.14 billion through 2029. The largest is the $400 million design-build Indefinite Delivery/Indefinite Quantity contract awarded by ENDIST Far East on June 21, 2024 (completion December 20, 2029), which establishes a framework for design-build construction and facilities maintenance across U.S. military installations in South Korea. Three $245 million single-award IDCs awarded by DoD Pacific Region and Army Installation Management Command Korean and Pacific Regions (all on October 5, 2023; completion October 4, 2028) support general construction repair and upgrade services for United States Forces Korea facilities. An $80 million single-award Job Order Contract awarded by ENDIST Far East (September 28, 2022; completion March 28, 2026) covers Sustainment, Restoration, and Modernization projects in Areas III and IV Korea-wide. A $45 million multiple-award design-build contract awarded by PACAF (September 28, 2023; completion September 27, 2025) supports construction and maintenance services across South Korea. A $30 million multiple-award design-build contract awarded by ENDIST Far East (September 30, 2021; completion September 29, 2024) covers Korea-wide design-build construction. Most recently, ENDIST Far East awarded a $9.2 million single-award Indefinite Delivery Contract (April 14, 2026; completion April 13, 2027) as a bridge contract covering Sustainment, Restoration, and Modernization work in Areas III and IV.

Recent delivery orders demonstrate the vendor's core service portfolio: a $5.82 million firm fixed-price order for drainage repair at General Flag Officers Quarters and Senior Officers Quarters at U.S. Army Garrison Humphreys (completion May 4, 2028); a $1.06 million order for emergency generator and automatic transfer switch replacement at three buildings at Suwon Air Base (completion September 19, 2027); a $4.73 million order for power supply distribution system repairs at Beacon Hill Switching Station, USAG Humphreys (completion December 26, 2025); a $1.85 million order for restroom facility construction at USAG Humphreys (completion January 26, 2024); and a $1.55 million order for steel structure shade construction at Gwangju Air Base (completion April 23, 2024). Work also spans smaller-scale tasks such as fire alarm system repairs, HVAC system maintenance, chiller and boiler replacements, water line replacement, drainage system construction, parking lot and pavement repairs, roof repairs, electrical and lighting upgrades, fall protection system installations, and building renovations.

Activity volume has declined sharply. The vendor recorded 57 awards in 2022, 52 in 2023, 26 in 2024, and 24 in 2025; only 6 awards are present in source data for 2026 through July 15, 2026. Seventeen awards with ultimate completion dates in the next twenty-four months carry combined potential value of $35.3 million, representing recompete exposure. All awards are issued as firm fixed-price delivery orders without set-aside designations and perform work exclusively in South Korea. The vendor has held a System for Award Management registration since 2006 and operates as a South Korea-based entity without U.S. domestic subsidiaries or teaming relationships in the award record.
