About the company

Nambu Service Co., LTD., a South Korea-based for-profit organization, operates as a prime contractor delivering facility operations, waste management, environmental remediation, and logistics support services exclusively to U.S. Army installations in the Pacific Region. The vendor competes under full-and-open competition with no SBA set-aside designations, holding 927 total prime awards with combined potential value of $73.5 million and combined obligated value of $23.4 million across recent activity.

Nambu's capability portfolio centers on base operations and grounds maintenance. The vendor's work spans janitorial and custodial services (287 awards), trash and waste collection and disposal (137 awards in hazardous and nonhazardous waste treatment, plus 209 awards specifically for trash collection), furniture and appliance movement (135 awards), HVAC duct cleaning, grounds maintenance including grass cutting, non-tactical vehicle parts supply, environmental remediation (removal and disposal of contaminated oil, water, and petroleum products from oil/water separators), and construction debris removal. Representative contracts include a $373,603.17 delivery order for grass cutting at Camp Carroll awarded January 1, 2025 (performance through December 2025); a $662,273.29 single-award indefinite delivery contract for removal water and contaminated oil/water separator services through August 2026 with multiple task orders ranging from $1,530 to $106,207; a $183,708.07 BPA call for trash pickup, transportation, and disposal at USAG Daegu and remote sites (January 15, 2023 through January 14, 2024); and a $1.7 million indefinite delivery contract for grass cutting and ground maintenance in the Daegu, Busan, Masan, and Kyongsan areas through December 2026.

Customer concentration is extreme and singular. The Department of the Army Installation Management Command Pacific Region accounts for 757 awards (82% of total awards) and $69.2 million in combined potential value (94% of total potential value). Four subordinate Army entities—Department of the Army Materiel Command Sustainment Command (29 awards, $1.5 million), Department of the Army (78 awards, $1.2 million), Department of the Army Materiel Command Expeditionary Contracting Command (46 awards, $803 thousand), and Department of the Army Pacific Command (13 awards, $775 thousand)—comprise the remaining 18% of awards and 6% of dollars. This concentration reflects Nambu's exclusive focus on supporting U.S. Army facilities in South Korea with no diversification across other federal agencies or mission sets.

Nambu holds seven active parent vehicles spanning five years of potential performance. The largest by task-order volume is Indefinite Delivery Contract W91QVN08D0036 (262 task orders, $5.7 million combined potential value, extending through various completion dates), followed by Blanket Purchase Agreement W91QVN18A0001 (60 task orders, $2 million); BPA W91QVN21A0004 for grass cutting (55 task orders, $659 thousand); a $1,403,850.39 single-award BPA for duct cleaning (running through April 2027); a $2.9 million single-award BPA for waste removal (through November 2027); a $2.8 million multiple-award BPA for trash removal services for military exercises (through November 2027); and a $1.19 million multiple-award BPA for furniture and appliance movement (through September 2029). Recent awards show consistent monthly task-order activity with firm fixed-price call values typically ranging from under $4,000 to $50,000, with occasional larger delivery orders for annual grass cutting and grounds maintenance contracts exceeding $250,000.

Activity has remained stable year over year at 55–65 awards annually from 2022 through 2025, with 22 awards recorded through September 2026 (representing partial-year data). Six awards with completion dates falling within the next twenty-four months carry combined potential value of $1.7 million, representing a modest recompete exposure in the near term. The vendor's registered status with SAM.gov since October 2007 and consistent award pattern across overlapping contract vehicles indicate a long-standing, institutionalized relationship with Army Installation Management Command Pacific Region. Nambu operates entirely as a prime contractor with no identified subcontract footprint in the source data. The vendor's concentrated customer base, geographic footprint (exclusively South Korea), mission specialization (facility operations for U.S. military installations), and full-and-open competition posture position it as a specialized provider with limited transferability across other federal markets or mission domains.
