Chin Ok Han

Chin Ok Han serves as a primary contracting representative for the 0411 Aq Hq Contract Augmented under the Department of the Army, overseeing the acquisition of facility sustainment, infrastructure modernization, and operational support services critical to U.S. Army installations, particularly in overseas garrisons such as USAG Humphreys and USFK. Responsible for managing complex procurement cycles aligned with FAR and DFARS guidelines, Chin ensures mission-critical infrastructure resilience through timely execution of construction, maintenance, and logistics contracts. Their work directly supports the agency’s mandate to maintain combat-ready environments by securing reliable, high-performance facilities and utilities systems. Chin maintains consistent working relationships with a core group of contractors including GLOBAL SYSTEMIZED INDUSTRY, 09CLEAN CO., LTD, KOREA CONTAINER POOL CO., LTD, NOKHWACHANGJO, and GLOBAL COMPANY ALLIANCE CO., LTD., primarily engaged in industrial and commercial construction, transportation, and facility maintenance services. These partnerships reflect a preference for established vendors with proven regional expertise and capacity to operate in austere, high-demand environments. Contractual engagements are typically performance-based, emphasizing schedule adherence, quality control, and compliance with military construction standards. Set-aside preferences are overwhelmingly non-targeted, with 92.3% of awards issued under full and open competition, reflecting a prioritization of capability and readiness over socioeconomic set-asides. Only 7.7% of acquisitions are designated for Local Area Set-Aside under FAR 26.2, indicating a strategic focus on leveraging local market capacity where operational necessity aligns with geographic constraints, rather than broad socioeconomic program participation. The procurement portfolio is heavily concentrated in NAICS 236210 (Industrial Building Construction), 236220 (Commercial and Institutional Building Construction), 237310 (Highway, Street, and Bridge Construction), and 484110 (General Freight Trucking, Local), with additional emphasis on 811111 (General Automotive Repair). This reflects deep expertise in military infrastructure lifecycle management, including structural upgrades, utility system repairs, road network maintenance, and vehicle support services essential to garrison operations.
