About the company
Quadra Control Services Limited, a Japan-registered foreign-owned for-profit corporation, provides school bus safety aide and attendant services and night monitor support to the Department of Defense Education Activity as a prime contractor operating exclusively under full-and-open competition with no set-aside designations. The company is a child entity within a larger corporate structure headquartered in Seoul, South Korea, and competes in open market solicitations for DoDEA student safety and transportation services across military-dependent schools in Japan and Okinawa.
Quadra Control Services Limited holds a narrow but deeply penetrated customer base. All 31 awards in the source data are issued by the Department of Defense Education Activity, representing 100% of the company's federal contract footprint and $19.8 million in combined potential value. The vendor operates across three single-award indefinite delivery contracts with DoDEA: a $5.4 million IDC for bus safety aide and attendant services in Japan military communities (10 delivery orders, $2.8 million combined potential value), a $3.7 million IDC for Okinawa bus safety services (11 delivery orders, $4.1 million combined potential value), and a $44 thousand IDC for night monitor services in Okinawa (6 delivery orders, $44 thousand combined potential value). Recent representative delivery orders include a $471 thousand firm fixed-price task order awarded November 1, 2025, for Japan safety aide and attendant services through July 31, 2026, a $374 thousand delivery order from November 1, 2024, for Okinawa safety aide and attendant services through July 31, 2025, and a $732 thousand order from November 1, 2022, for Japan bus safety attendants and aides through July 31, 2023.
Activity has remained relatively flat across the past five years — ranging from five to eight awards annually — with $10.6 million in combined dollars obligated against the $19.8 million potential value, representing a 54% obligation rate. Three awards (combined potential value $806 thousand) reach ultimate completion within the next twenty-four months. The vendor's capability portfolio is narrowly focused on NAICS 541590 (School and Employee Bus Transportation) work covering 24 awards and NAICS 561720 (Office Administrative Services) covering 7 awards, with the bulk categorized as support-professional physical security and badging services (PSC 3F). Place of performance spans Japan and Okinawa military installations, with performance periods typically aligned to the academic calendar (November through July or August through October). Quadra Control Services Limited operates exclusively as a prime contractor with no documented subcontract activity across the federal portfolio.
