As an 8H-certified entity headquartered in Seoul, the company leverages its local presence to deliver rapid mobilization and culturally attuned project execution for U.S. government clients. While no additional federal certifications are listed, its consistent award history reflects proven reliability in delivering mission-critical construction services under the DoD’s installation support framework.
