About Cao-Dac Corp
Cao-Dac Corp Headquarters Division, doing business as Cao-Dac Corp, is an SBA-certified Economically Disadvantaged Women-Owned Small Business (EDWOSB) and Women-Owned Small Business (WOSB) based in Sterling, Virginia, that delivers facility maintenance, cleaning, janitorial, and grounds-keeping services to federal agencies exclusively as a prime contractor under total small business set-asides. The vendor operates as a for-profit Subchapter S corporation and competes predominantly under WOSB and EDWOSB set-asides across a narrow federal customer base.
Cao-Dac Corp's capability portfolio centers on recurring facility support: janitorial and custodial cleaning services, mowing and grounds maintenance, and minor facilities repairs at federal recreation areas and office buildings. The vendor's federal work splits between two distinct customer streams. The dominant customer is the General Services Administration Public Buildings Service National Capital Region, which accounts for 116 awards (72% of all prime awards) and $23.4 million in combined potential value — nearly all facility maintenance and janitorial services at federal office buildings. The secondary customer is the Department of the Army Corps of Engineers Huntington District, which placed 35 awards valued at $2.7 million for cleaning and grounds maintenance at recreational lakes (Burnsville Lake and Summersville Lake in West Virginia). The Department of the Army Corps of Engineers broadly accounts for 33 additional awards ($6.3 million), though the Huntington District concentration suggests that total Corps exposure sits with the Huntington office. Together, these three customer entities cover 100% of Cao-Dac Corp's award footprint. The vendor holds no subcontracting relationships and no positions on GWACs, BPAs, or agency-wide IDIQs outside the Corps' single-award IDCs.
Cao-Dac Corp operates under three single-award Indefinite Delivery Contracts with the Army Corps of Engineers Huntington District: a $3.084 million cleaning services contract at Burnsville Lake (awarded March 2023, extending through December 2027); a $1.15 million mowing and maintenance contract at Burnsville Lake (awarded May 2024, extending through December 2028); and a $725 thousand cleaning and janitorial contract at Summersville Lake (awarded January 2026, extending through December 2030). These three IDCs generate the majority of the vendor's 35 task orders with the Huntington District. Representative task orders include a $142,653 cleaning services delivery order at Summersville Lake (awarded February 2026, completing December 2026) and a $135,522 cleaning services task order at Burnsville Lake (awarded January 2026, completing December 2026), both designated as total small business set-asides. Cao-Dac Corp's GSA work, by contrast, does not appear in the source data with individual contract line detail; the source reflects 116 GSA awards but lists only Corps work by award description.
Activity has declined over the past three years — eight awards in 2023, six in 2024, three in 2025, and four in 2026 — suggesting either pipeline contraction or changes in how task order activity is being reported. Only two awards (combined potential value $278 thousand) face ultimate completion within the next twenty-four months, creating minimal recompete exposure. The vendor's award portfolio totals $32.4 million in combined potential value, with $21.1 million (65%) obligated to date.
