Heesong Geotek Co., LTD.

Heesong Geotek Co., LTD., a South Korean for-profit geotechnical services firm headquartered in Seongnam-si, Gyeonggi Province, operates exclusively as a prime contractor delivering geotechnical drilling, soil sampling, in-situ testing, and seismic analysis to the U.S. military at overseas installations under the Status of Forces Agreement acquisition framework. The vendor competes in full-and-open (non-set-aside) federal procurement with no SBA designations and performs all work in South Korea.

Heesong Geotek's customer footprint is highly concentrated with a single military engineering organization: the Department of the Army Corps of Engineers Engineering District Far East accounts for 39 of 44 total awards and $9.24 billion in combined potential value, representing 100% of the vendor's active federal customer base across four distinct agencies. The remaining three customer relationships — the Department of the Army Corps of Engineers (3 awards, $268 thousand), the Office of Naval Research (1 award, $89 thousand), and the Office of the Secretary of Defense (1 award, $51 thousand) — are marginal by volume and dollars. This concentration reflects Heesong Geotek's specialization in a narrow but recurring military need at U.S. bases in the Republic of Korea.

The vendor holds a single-award Indefinite Delivery, Indefinite Quantity contract with the Army Corps of Engineers Engineering District Far East valued at $1.88 million and running through July 14, 2027. Six delivery orders totaling approximately $438,018 have been issued to date against this IDIQ. Representative task orders include a $123,744 geotechnical drilling and sampling contract (April 2024), a $82,560 drilling services delivery order at U.S. Army Garrison Humphreys (February 2025), a $61,440 site-specific seismic study across Camp Carroll, Camp Mujuk, and Osan Air Base (May 2025), and a $51,261 geotechnical investigation at Pohang Air Base and USAG Humphreys (November 2025). The most recent award, issued January 21, 2026, is a $30,692 delivery order for runway infrastructure work at USAG Humphreys with completion targeted for April 21, 2026. Historical awards span 2019–2024 with individual delivery orders ranging from sub-$25,000 to $188,443 in value.

Activity has been episodic rather than sustained — two awards in 2019, three in 2020, then a gap through 2023, followed by four awards in 2024 and three in 2025. The vendor's capability portfolio, indexed by NAICS and PSC codes, splits between Oil and Gas Field Machinery and Equipment Manufacturing and Support Activities for Nonmetallic Minerals Mining (25 and 19 awards respectively) and centers on Equipment and Materials Testing (35 awards) and Special Studies/Analysis–Geotechnical services (8 awards), reflecting the drilling and subsurface characterization work performed at forward-deployed military installations.
