About the company
Challenge Unlimited, Inc., a tax-exempt AbilityOne non-profit organization based in Alton, Illinois, delivers custodial services, grounds maintenance, landscaping, pest control, and facility operations support to federal agencies as a prime contractor (98% of recent awards) under the AbilityOne program designation, which certifies the organization's mission to employ individuals with disabilities while competing without socioeconomic set-asides.
The organization's federal portfolio spans 1,149 awards with $825.3 million in combined potential value, concentrated overwhelmingly in facility services work under NAICS 561720 (Janitorial Services) and PSC 7610 (Housekeeping-Custodial Janitorial), with 785 awards for janitorial work and 238 for landscaping. Recent custodial delivery orders exemplify the work: a $737,816 Operation Year 3 custodial services order from the Department of Defense Northeast Region at Fort Leonard Wood, Missouri (July 2026); a $3,135,434 custodial services order from the Department of the Army Southwest Region at Fort McCoy, Wisconsin (March 2025); and a $1,583,710 janitorial services order from the General Services Administration Region 4 in Jackson, Mississippi (December 2025). Grounds maintenance work includes a $2,524,283 delivery order for grounds, pest control, and pavement clearance at Naval Station Great Lakes (November 2025) and a $29.8 million indefinite-delivery contract for grounds maintenance, landscaping, and pest control at Scott Air Force Base under the Defense Health Agency (awarded October 2024, ceiling through October 2029).
Customer concentration sits with the Department of the Air Force Air Mobility Command (267 awards, $298.4 million combined potential value) and the Department of the Army Installation Management Command, split between the Southwest Region (237 awards, $123.1 million) and Northeast Region (165 awards, $88.5 million). Together, these three customer offices account for the bulk of Challenge Unlimited's portfolio by both volume and dollars. The General Services Administration Public Buildings Service (primarily Region 5 and Region 6) accounts for 127 awards across $61.8 million, and the Defense Commissary Agency has awarded 10 contracts worth $58.2 million for shelf stocking and custodial operations at Scott Air Force Base, Fort Hood, Fort McCoy, and Charleston Naval Weapons Station. The portfolio covers 46 distinct federal customer agencies, indicating broad government reach.
Challenge Unlimited holds 16 active indefinite-delivery vehicles, anchoring its prime work. The largest include a $29.8 million grounds maintenance IDIQ with Naval Facilities Engineering Command at Naval Station Great Lakes (awarded October 2025, completion October 2030); a $25 million custodial services IDIQ with Air Mobility Command at Scott Air Force Base (awarded October 2023, completion October 2028); a $17.7 million custodial services IDIQ with the Department of Defense Southwest Region at Fort McCoy (awarded March 2026, completion February 2031); and a $18.3 million custodial and related services IDIQ with GSA Region 5 for multiple Illinois and Ohio courthouse and federal buildings (awarded December 2022, completion November 2026). Additional vehicles include a $14.99 million custodial IDIQ with the Department of Defense Northeast Region at Fort Leonard Wood (awarded July 2023, completion June 2028) and a $12.86 million janitorial and related services IDIQ with GSA Region 6 at the Richard Bolling Federal Building in Kansas City, Missouri (awarded July 2023, completion June 2027). These vehicles support hundreds of delivery orders issued by customer agencies and regional offices.
Activity has remained steady, with 49 awards in 2022, 48 in 2023, declining to 30 in 2024 and recovering to 33 in 2025, with 23 recorded through mid-September 2026. Twenty-two awards carrying $62 million in combined potential value reach ultimate completion within the next twenty-four months, representing a near-term recompete cliff concentrated in Army, Air Force, and GSA regional facility services contracts.
SCI-reported invoicing on federal service contracts above the $150,000 threshold reached $299 thousand in FY2022, $308 thousand in FY2023, and $322 thousand in FY2024, with no FY2025 data in the source. The low SCI footprint reflects Challenge Unlimited's dominance in delivery-order work and smaller, task-order-based awards that may fall below the SCI reporting threshold or are captured under indefinite-delivery vehicle ceilings rather than as standalone service contracts. The available SCI data showed roughly 3 FTEs in FY2022–FY2023 and 30.9 FTEs in FY2024 across a mix of prime and named subcontractor records, though the fragmented FY2025 data suggests reporting gaps. Government-paid hourly rates on SCI contracts ranged from $48.73/hr at the 10th percentile to a median of $52.55/hr and $65.18/hr at the 90th percentile, indicating largely standard custodial and grounds-labor pricing without premium rate concentration.
Challenge Unlimited operates as a pure prime contractor; subcontractor engagement is minimal (2% of awards are sub-awards), and SCI records show zero average sub-hours share across prime contracts. The organization builds its own delivery teams for custodial and grounds work at military installations and federal buildings across the Midwest and East Coast. Grant work is secondary: the vendor has received sub-awards under the Social Services Block Grant and State Option Services Reinvestment (SOSR) programs from the Illinois Department of Human Services, as well as one sub-award for three medium-duty paratransit vehicles, reflecting the AbilityOne program's broader mission to fund employment and social services for individuals with disabilities. These grant activities do not drive the federal procurement footprint.
Challenge Unlimited competes full-and-open without small-business or other socioeconomic set-asides; its federal qualification stems from its AbilityOne designation and demonstrated track record in facility services at Department of Defense installations and federal buildings. The vendor's sustainability depends on recompete success at Fort Leonard Wood, Fort McCoy, Scott Air Force Base, Naval Station Great Lakes, and GSA regional courthouses and federal buildings—a concentrated and highly competitive landscape dominated by large facilities management primes and incumbent custodial providers.
