About this agency
The Department of the Army Materiel Command Expeditionary Contracting Command Regional Contracting Office Osan 411th CSB is a defense contracting office executing the Army's regional procurement mission at Osan Air Base, South Korea. The office has awarded four federal contracts with a combined potential value of $1.1 million, all fully obligated, since 2015.

Across the all-time portfolio, contract activity peaked in 2015 with three awards; the office recorded one award year-to-date in 2026. Distinct prime contractors number three across the lifetime portfolio.
The competitive base is highly concentrated. Over the last five years, Yuil Eng. & Const. Co., Ltd holds 100 percent of recorded awards and 98 percent of combined potential value, covering the single recent award on record. All four historical awards carry no set-aside designation.
No recent contract opportunities are recorded against this office. The low transaction volume, extended gaps between awards, and absence of current solicitations suggest minimal active procurement workload at this regional contracting office.
