About this vehicle

Department of the Army Installation Management Command Korean Region awarded this multiple-award IDIQ for general construction and repair work on October 5, 2023, with ordering authority extending through October 4, 2028. The vehicle carries a $245 million shared ceiling and unrestricted (no set-aside) competition across all task orders.

Ordering activity remains robust but is decelerating. The vehicle has generated 309 task orders to date, obligating $137.4 million (98% of combined potential value across all awarded orders). Order volume peaked in 2024 at 172 orders, declined to 116 in 2025, and has slowed to 21 through June 2026, suggesting either inventory depletion, shifting demand, or concentration of spend into fewer, larger awards. The most recent task order was issued June 1, 2026.

Work scope spans repair and new construction under $2 million per order, with actual delivery orders addressing barracks renovation, infrastructure repairs, HVAC and mechanical system overhaul, electrical and water utility upgrades, drainage and pavement remediation, and facility-specific modernization at U.S. military installations in South Korea. Representative recent awards include $3.9 million for emergency backup generator repair (Osan Air Base, September 2025), $3.5 million for barracks fire suppression system repair (Camp Hovey, September 2025), and $2.8 million for conventional munitions shop structural repair (Kwangju Air Base, October 2025).

Competition concentrates moderately among five primes holding 49 percent of task orders: Sori E&C Co., Ltd. (32 orders, $24.7 million potential value), Seong Bo Const. Ind. Co., Ltd. (29 orders, $20.8 million), Krima Construction Corp. (32 orders, $11 million), Seojin Construction Co., Ltd. (36 orders, $7.7 million), and Yuil Eng. & Const. Co., Ltd. (23 orders, $10.1 million). These five firms and a wider field of 17 additional primes collectively yield no single dominant player. Sori E&C, Seong Bo, Krima, Elrim, and Yuil together hold 56 percent of combined potential value.

Customer concentration is pronounced: Department of the Army Installation Management Command Pacific Region places 168 orders ($61.1 million potential value, 54% of portfolio), followed by the Army Korean Region (79 orders, $48.9 million), and Air Force Pacific Air Forces (54 orders, $27.7 million). Remaining Army and Air Force units account for the remainder.

Task-order values span a wide range. Most fall between $30 thousand and $3.9 million, with firm fixed pricing predominant and completion windows of 6 to 18 months typical. Orders are geographically dispersed across U.S. military installations throughout South Korea, including Camp Casey, Camp Humphreys, Camp Carroll, Camp Walker, Osan Air Base, and Kunsan Air Base, with subordinate work at regional facilities and forward operating locations.

Two years remain on the ordering authority, though recent award pace suggests substantial remaining capacity has not been consumed. New entrants face an established contractor base with demonstrated South Korea operations experience, but the moderate concentration and continuing order flow indicate viable pursuit lanes, particularly for firms capable of managing $1 million to $3 million renovation and infrastructure projects on compressed timelines.

Description

This IDIQ funded by OMA will focus on the repair and new construction for both interior and exterior needs. All specifications will be followed in accordance to the contract.
