About the company
Defense Contracting Activity, LLC (DCA), operating its Nula Division and doing business as DCA, is a service-disabled veteran-owned small business based in Chantilly, Virginia that provides armed and unarmed security guard services to federal civilian agencies exclusively as a prime contractor, with no subcontractor engagement. DCA operates 100% as a prime across 54 federal awards with combined potential value of $121.5 million, competing predominantly on full-and-open procurements through the GSA Multiple Award Schedule rather than set-aside vehicles.
DCA's customer concentration is heavily skewed toward the Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) sub-agencies. The top five APHIS component organizations account for 89% of awards by count: APHIS Wildlife Services (18 awards, $7 million combined potential value), APHIS Plant Protection and Quarantine (15 awards, $18.3 million), generic APHIS (8 awards, $1.9 million), APHIS Marketing and Regulatory Programs Business Services (4 awards, $1 million), and APHIS Veterinary Services (2 awards, $14.7 million). However, the potential-value distribution reveals three significantly larger anchors: the Environmental Protection Agency (1 delivery order, $27.9 million for armed security officer services at the EPA's Research Triangle Park campus through February 2029), the Department of Agriculture's Agricultural Research Service (1 award, $25.2 million), and the GSA Federal Acquisition Service (1 award, $24 million). USDA APHIS still dominates by contract volume, but EPA's single large delivery order represents 23% of DCA's combined potential value.
DCA operates primarily through the GSA Multiple Award Schedule, where 55 task orders carry $99.2 million combined potential value. The company also holds three single-award BPAs: a $1.6 million Wildlife Services BPA at Pocatello, Idaho (through January 2027); a $1 million APHIS Millville, Utah armed guard services BPA (through June 2028); and an $8 million USDA Plant Protection and Quarantine BPA established August 1, 2026 (through July 2031). Representative recent work includes a $27.9 million EPA delivery order for armed security at Research Triangle Park (issued March 2024, self-performed with 55 FTEs in FY2025), a $1.54 million USDA Plant Protection and Quarantine BPA call for armed security at Moore Air Base in Edinburg, Texas (issued August 2026, performance through July 2027), a $7.59 million USDA Veterinary Services delivery order for security at the National Centers for Animal Health facility in Ames, Iowa (issued August 2022, extending through August 2027), and multiple $225K–$370K BPA calls from APHIS for guard services at Pocatello, Chantilly, and Millville locations.
SCI-reported invoiced activity shows scaling over the past four fiscal years. DCA reported $6.2 million across 76.8 FTEs in FY2022, $6.2 million across 73.3 FTEs in FY2023, $9.4 million across 79.6 FTEs in FY2024, and $11.5 million across 139 FTEs in FY2025, reflecting a 75% growth in FTE deployment year-over-year from FY2024 to FY2025. Government-paid hourly rates on federal services contracts captured in SCI ranged from $37.88/hr at the 10th percentile to a median of $40.93/hr, with senior labor reaching $107.65/hr at the 90th percentile. DCA self-performs all labor with zero subcontractor engagement across SCI-reportable contracts.
Activity has softened recently. DCA received five awards in 2022, six in 2023, three in 2024, two in 2025, and three in 2026 year-to-date, suggesting a declining award velocity after the APHIS relationship matured. Only three awards (combined potential value $9.4 million) face ultimate completion within the next twenty-four months and therefore represent recompete exposure: the Moore Air Base BPA call (July 2027) and two smaller legacy contracts expiring before mid-2027. The substantial EPA and Agricultural Research Service awards do not complete until 2029 and beyond, reducing near-term recompete cliff risk for DCA but also indicating limited new-work pipeline in the visible source data.
