About Janghak E&C
Janghak E&C is a South Korean for-profit construction and facilities management firm registered in the System for Award Management (SAM) since January 15, 2002, with its primary address located in the Yongsan District of Seoul. The company specializes in providing comprehensive construction, repair, and facility upgrade services to United States military installations in South Korea, primarily supporting U.S. Forces Korea (USFK) across multiple military bases. While limited publicly available information exists about the company's broader corporate background, its extensive federal contract history demonstrates a focused expertise in infrastructure maintenance and modernization projects for U.S. Department of Defense facilities.
Through its federal contract awards, Janghak E&C has performed a wide range of construction and maintenance services, consistently working as a prime contractor for various military agencies. These services include roof repairs, building renovations, sprinkler system replacements, HVAC unit repairs, electrical system upgrades, fire protection system maintenance, storm drainage improvements, bathroom and interior space renovations, concrete work, lighting system installations, and facility demolition projects. The primary funding agencies for these contracts have been the U.S. Army Installation Management Command Pacific Region, Pacific Air Forces, Army Pacific Command, and U.S. Army Corps of Engineers Engineering District Far East. Notably, none of Janghak E&C's contract awards have utilized small business or disadvantaged business set-aside designations, indicating the company competes on an unrestricted basis.
Janghak E&C currently holds multiple significant indefinite delivery, indefinite quantity (IDIQ) contracts, most notably a $245 million multiple-award IDIQ for general construction, repair, and upgrade of USFK facilities, awarded by the Pacific Region of the U.S. Army Installation Management Command. This contract, which runs from October 2023 to October 2028, allows for individual delivery orders up to $2 million and covers a comprehensive range of infrastructure sustainment and modernization projects. The contract enables rapid execution of minor military construction and repair work across U.S. Forces Korea facilities. Task orders under this and similar IDIQ contracts have been issued by agencies including Pacific Air Forces, demonstrating the contract's flexibility in supporting critical infrastructure needs. These IDIQ vehicles provide a strategic mechanism for the U.S. military to efficiently manage and execute construction and maintenance projects at its South Korean installations.
