About the company
Didlake Inc., doing business as Didlake Occupational Center, is an AbilityOne nonprofit agency providing custodial, janitorial, grounds maintenance, and administrative support services to federal agencies exclusively as a prime contractor, with $2.05 billion in combined potential value across 495 awards and $1.33 billion obligated. The organization operates in-house delivery with zero material subcontractor dependency on SCI-reportable prime contracts and pairs meaningful employment and rehabilitative services for individuals with disabilities with large-scale facility operations across defense and civilian installations. Didlake is headquartered in Manassas, Virginia, and holds no small-business set-aside designations; all prime awards are full-and-open competitive.
Didlake's customer footprint centers on the Department of the Navy and General Services Administration. The top five funding agencies account for 73% of combined potential value: the Navy's Naval Facilities Engineering Command (38 awards, $483.5 million), GSA Public Buildings Service National Capital Region (73 awards, $344.9 million), DoD Washington Headquarters Service (10 awards, $283.4 million), Navy Installations Command (116 awards, $235 million), and the Department of Energy Office of Management (8 awards, $138.4 million). Volume concentration tilts toward Navy Installations Command (116 awards, 51% of top-five count), while dollar concentration tilts toward Naval Facilities Engineering Command and Washington Headquarters Service. Didlake's most visible contract is a $133.1 million definitive for AbilityOne custodial services at the Pentagon across multiple locations (floors 1, 5, basement, mezzanine, Pentagon Library and Conference Center, North Village/Compound, and Pentagon Athletic Center) awarded May 27, 2022, through December 31, 2031. Representative work includes a $27.7 million definitive for janitorial and related services at the NIST Gaithersburg campus (May 1, 2025 through April 30, 2030), a $20.973 million indefinite-delivery contract for landscaping services at NASA Wallops Flight Facility (January 1, 2026 through December 31, 2030), and a $22.574 million single-award IDC for custodial and related services at the Eisenhower Executive Office Building and White House West Wing (October 1, 2025 through April 30, 2027).
Didlake holds five primary Navy and GSA indefinite-delivery vehicles anchoring its facility services footprint. The largest parent vehicles by task-order volume are Indefinite Delivery Contract N4008509D5059 (45 task orders, $29 million combined potential value) and N4008520D0004 (39 task orders, $28 million combined potential value) with the Naval Facilities Engineering Command, followed by Indefinite Delivery Contract 47PD0322D0003 with GSA Public Buildings Service Region 3 (31 task orders, $1.8 million combined potential value), N4008520D0046 with the Navy (27 task orders, $88.8 million combined potential value), and N4008515D0063 (20 task orders, $55.6 million combined potential value). Didlake also holds a Federal Supply Schedule contract with GSA Federal Acquisition Service (57 unique labor categories, $29.94–$105.41/hr, no security-cleared roles) and a $49.5 million single-award IDC with GSA National Capital Region for custodial services at the FDA White Oak Campus (through February 28, 2026, extended through 2027 successor contracts). The organization's work spans custodial operations, grounds maintenance, specialized cleaning (window washing, floor care, carpet cleaning, event support), mailroom and distribution services, and warehouse support, with pricing consistently firm fixed-price or labor-hour and no subcontractor reliance.
Recent activity remains stable at 20–28 awards annually across the five-year window (2022: 28 awards; 2023: 19; 2024: 26; 2025: 25; 2026: 26). SCI-reported invoicing totaled $65.6 million over FY2022–FY2024 (176–192 FTEs annually) at a median government-paid rate of $62.27/hr, with a ten-percentile low of $41.09/hr and ninety-percentile high of $120.37/hr. Didlake self-performed 100% of contractor hours on SCI-reportable prime contracts with zero average sub-hours share, reflecting its labor-intensive, in-house delivery model paired with AbilityOne employment mission. Twenty-one awards carrying combined potential value of $111.6 million reach ultimate completion inside the next twenty-four months, creating recompete opportunity across Navy Installations Command, GSA, and Department of Energy customer accounts. The vendor's award portfolio is concentrated in two NAICS categories: Janitorial Services (258 awards) and Landscaping Services (93 awards), representing 260 of 315 awards in the top category set.
