Seong Nam City Hall

Seong Nam City Hall, a South Korea-based municipal water authority and non-profit organization, supplies potable water to U.S. Army installations K-16 and Camp Tango in South Korea as a prime contractor under firm fixed-price delivery orders, with no set-aside designation and 100% customer concentration at the U.S. Army Installation Management Command Pacific Region.

Seong Nam City Hall operates exclusively as a full-and-open prime contractor, holding a single $1.05 million ten-year indefinite delivery contract awarded February 1, 2023, and running through January 31, 2033. All twenty awards in the source record are delivery orders against this parent IDC, issued by IMCOM Pacific Region for water service provision. The vendor's capability portfolio is narrowly scoped to potable water supply — NAICS 531000 (Water Supply and Irrigation Systems) and PSC 5100 (Utilities—Water) represent the entirety of its federal work. Recent delivery orders include a $165,000 firm fixed-price order for water service from October 1, 2024, through September 30, 2025; a $132,100 order covering October 1, 2023, through September 30, 2024; and a $111,700 order issued March 1, 2026, through October 31, 2026. Individual delivery-order ceiling values have historically ranged from approximately $31,000 to $165,000, with performance periods typically spanning six to twelve months.

Customer concentration is absolute: the Department of the Army Installation Management Command Pacific Region accounts for all twenty awards and the full $4.4 million combined potential value. Activity has been irregular — one award in 2022, three in 2023, one in 2024, two in 2025, and two in 2026 — tracking the operational and budget cycles of the two installations served. The vendor has no subcontract footprint and no vehicle holdings beyond the single parent IDC. Of the $4.4 million in combined potential value, $1.5 million has been obligated (35%), with one award completion in the next twenty-four months valued at $112 thousand. Seong Nam City Hall has held the designation as sole water service provider for K-16 and Camp Tango since October 2021, indicating continuity as the chosen local utility authority for these installations rather than competitive procurement exposure.
