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) based in Mobile, Alabama, that operates as a prime contractor (100% of awards) in federal infrastructure and facilities maintenance, predominantly under total small business and SDVOSB set-asides.

The company specializes in concrete construction, maintenance, repair, and alteration services for federal lands. Primary work includes comfort station and bathhouse rehabilitations, roof replacements, bridge repairs, road maintenance and reconstruction, utility system upgrades, facility renovations, campground improvements, and sewage lagoon remediation across national wildlife refuges, national forests, recreation areas, and other federal properties. Representative prime contracts include a $2.34 million delivery order for performance and rehabilitation of three sewage lagoons at Petrified Forest National Park (Department of the Interior, September 2024), a $2.29 million crew quarters facility construction at Humboldt-Toiyabe National Forest in Nevada (Department of Agriculture Forest Service, June 2024), a $2.45 million maintenance shop replacement at Sandhill Crane National Wildlife Refuge in Mississippi (Department of Interior Fish and Wildlife Service, September 2024), a $1.355 million definitive contract for high-game proof fencing in Cameron County, Texas for cattle fever tick eradication (Department of Agriculture Animal and Plant Health Inspection Service, May 2025), and a $1.31 million tour loop rehabilitation at Santa Ana National Wildlife Refuge in Texas (Department of Interior Fish and Wildlife Service, November 2024).

Guardian DB Services holds three significant federal indefinite delivery vehicles anchoring the portfolio. The $250 million Great American Outdoors Act Multiple-Award Task Order Contract (MATOC) with the Department of Interior Fish and Wildlife Service, awarded January 1, 2022 through June 30, 2027, funds 38 task orders worth $25.5 million in combined potential value and represents the primary vehicle enabling nationwide work across interior and forest service properties. The $50 million Blanket Purchase Agreement with the Department of Agriculture Forest Service Region 1–Region 4 for Forest Engineering and Road Maintenance (FERM) services, awarded October 2, 2023 through August 31, 2033, covers road maintenance and construction across 10 states in the northern and central regions. The $20 million single-award Indefinite Delivery Contract with the Department of Agriculture Forest Service Region 2 (Rocky Mountain Region), awarded July 1, 2025 through June 30, 2030, supports road maintenance and forest support services across Colorado, Nebraska, South Dakota, and Wyoming.

Customer concentration is heavily weighted to interior and forest service civilian agencies. The Department of Interior Fish and Wildlife Service Headquarters Region 9 dominates potential value with the $250 million MATOC ceiling, while the Department of Agriculture Forest Service R1-Northern Region accounts for $50 million (the FERM BPA). By award count, the Fish and Wildlife Service leads with 12 awards, followed by Forest Service Region 8–Southern Region with 10 awards and Fish and Wildlife Service Region 2 with 5 awards. Combined, the top five customer agencies account for 94% of potential value and 59% of awards by count. Within recent delivery order activity, awards cluster across regions and agencies: Fish and Wildlife Service Regional Offices (Regions 2, 4, 6, 8, and Intermountain) anchor the majority, with secondary work through Forest Service regions and the National Park Service Intermountain Region.

Work is performed nationwide (continental United States and Hawaii) with administrative oversight in Mobile, Alabama. Primary NAICS categories reflect construction specialization: Commercial and Institutional Building Construction (41 awards), Highway, Street, and Bridge Construction (6 awards), and All Other Specialty Trade Contractors (5 awards). Nearly all recent awards carry firm fixed-price structures under total small business or SDVOSB set-asides. Activity has grown from 16 awards in 2022 to a peak of 15 awards in both 2024 and 2025, with only 2 awards in 2026 to date. Seven awards totaling $4.1 million in combined potential value face completion within the next twenty-four months, representing modest recompete exposure relative to the $250 million MATOC ceiling.
