Guardian DB Services,Llc

Guardian DB Services, LLC, doing business as Don Brooks, is a service-disabled veteran-owned small business (SDVOSB) and veteran-owned small business (VOSB) headquartered in Mobile, Alabama that operates as a prime contractor delivering construction, infrastructure maintenance, repair, and facilities services to federal land management agencies under total small business and SDVOSB set-asides. The vendor competes exclusively under set-aside vehicles — 100% of its recent awards carry Total Small Business, Service-Disabled Veteran-Owned Small Business, or SDVOSB sole-source designations.

Guardian DB Services specializes in concrete construction, road maintenance and reconstruction, building renovation, roof replacement, bridge repair, utility system upgrades, and related infrastructure work across federal wildlife refuges, national forests, national parks, and recreation areas. Representative work includes a $1.76 million delivery order from the Bureau of Reclamation for power infrastructure maintenance at Yuma East Yard in Arizona (August 2026, Great American Outdoors Act MATOC), a $2.34 million delivery order from the Department of the Interior for sewage lagoon rehabilitation at Petrified Forest National Park in Arizona (September 2024, MATOC), a $2.46 million delivery order from Fish and Wildlife Service Region 1 for maintenance shop replacement at Sandhill Crane National Wildlife Refuge in Mississippi (September 2024, MATOC), and a $3.98 million delivery order from Forest Service Region 6 for forest road rehabilitation in the Carson Priority Fireshed in Nevada (July 2023, funded under IIJA). The vendor also holds a $1.36 million SDVOSB contract from the Animal and Plant Health Inspection Service for high-game proof fencing construction in Cameron County, Texas (May 2025).

Customer concentration is driven overwhelmingly by federal land management agencies. The top five customer entities by award count account for 59% of recent awards, led by the Department of Agriculture Forest Service Region 8 (Southern Region) with 13 awards and $11.2 million combined potential value, followed by the Department of the Interior Fish and Wildlife Service with 12 awards and $4.4 million combined potential value. By potential value, however, the portfolio is dominated by two large indefinite-delivery vehicles: the $250 million Great American Outdoors Act MATOC from Fish and Wildlife Service Headquarters Region 9 and a $50 million Blanket Purchase Agreement from Forest Service Region 1 for Forest Engineering and Road Maintenance services. These two vehicles account for 93% of the vendor's combined potential value and dwarf the smaller delivery orders and definitive contracts issued against them. Guardian DB Services holds a third major IDC — a $20 million Indefinite Delivery Contract from Forest Service Region 2 (Rocky Mountain Region) for road maintenance services effective July 1, 2025 through June 30, 2030 — plus two recently awarded single-award IDIQs from Forest Service Region 8 totaling $8 million for road and roadside maintenance at Ozark-St. Francis National Forest (August 2026).

Activity has remained steady across the past five years at 8 to 16 awards annually, with 11 awards in 2026 year-to-date. Nine awards carrying combined potential value of $5.1 million are scheduled for completion within the next twenty-four months and therefore face recompete risk. The vendor operates as a pure prime contractor with zero subcontract awards in the source data and zero reliance on named subcontractors across SCI-reportable prime contracts. SCI-reported invoicing ran $17.3 million in FY2025 across 29.4 FTEs, with all labor self-performed by the prime. Work is performed nationwide across CONUS, with place-of-performance locations spanning Arizona, Nevada, Florida, Louisiana, Texas, Colorado, Alabama, Georgia, Mississippi, Oklahoma, and other states where federal lands require infrastructure maintenance and construction services. The vendor's typical contract vehicles include the Great American Outdoors Act MATOC (42 task orders, $28.4 million combined potential value) and smaller single- and multiple-award IDIQs, BPAs, and definitive contracts issued directly by regional Forest Service and Fish and Wildlife Service offices under firm fixed-price structures and total small business set-asides.
