About the company
Sunjin Engineering & Architect Co., LTD. Architecture Division - Global operates as a subcontractor delivering architect-engineer (A-E) services to the Department of Defense, with all four recent federal awards routed through Jacobs Government Services Company as prime contractor. The vendor holds no prime contract vehicles and competes exclusively in subcontractor roles on fixed contracts rather than through government-wide acquisition channels.
All four awards target a single customer program: engineering services for the Korea Air and Space Operations Center (KAOC) at Osan Air Base, Korea. The vendor received an in-scope change order in March 2024, followed by three additional A-E service task awards between January and April 2025. Place of performance is Osan Air Base, Korea. The work falls squarely within NAICS 541330 (Engineering Services), with scope focused on facility engineering, design, and architectural support for a forward-deployed U.S. Air Force operations center.
Activity has accelerated from one award in 2024 to three in 2025, though the portfolio remains small and concentrated within a single prime-customer pairing. The vendor's entire federal footprint is anchored to Jacobs Government Services Company as prime, suggesting either a teaming arrangement limited to the KAOC program or an early-stage subcontractor relationship with limited diversification across other Jacobs task orders or distinct primes. Sunjin Engineering & Architect Co., LTD. operates as a corporate for-profit entity; the source carries no SBA designations (8(a), HUBZone, SDVOSB, or other set-asides) and does not indicate minority or disadvantaged-business ownership status.
