Ama Diversified Construction Group

Ama Diversified Construction Group, a minority-owned, Hispanic American-owned 8(a) certified small business based in Petaluma, California, is a prime contractor delivering water, wastewater, and construction infrastructure services to federal agencies under Total Small Business and 8(a) sole-source set-asides. The company operates as a Subchapter S corporation and competes predominantly under 8(a) and small business set-aside vehicles; among 212 total prime awards in the source data, all are primes with zero subcontractor awards recorded, positioning the vendor as a built-to-serve player in the federal construction market rather than a feeder to larger primes.

Customer concentration is heavily regional and agency-specific. The top five funding agencies account for 81% of award count but the potential-value picture diverges sharply: the Department of the Navy's Naval Facilities Engineering Command anchors the portfolio with 8 awards worth $258.7 million (primarily the single $249 million Wet Utilities Construction Projects NAVFAC Southwest Area of Responsibility indefinite delivery contract awarded December 2024), while the Department of the Interior Fish and Wildlife Service Headquarters Region 9 holds a single $250 million MATOC. These two vehicles alone represent $508.7 million of the vendor's $659.4 million combined potential value. By contrast, the National Park Service Pacific West Region—Ama's most active customer by award count with 99 orders—carries only $72.9 million combined potential value, reflecting the predominance of smaller facilities maintenance and repair task orders. The Indian Health Service and U.S. Army Corps of Engineers round out the top five by volume but represent modest dollar exposure ($7.3 million and $19.9 million, respectively).

Ama operates three primary indefinite delivery vehicles. The $250 million Department of the Interior Multiple-Award Task Order Contract (MATOC), set aside for total small business and expiring June 30, 2027, provides construction, alteration, repair, and maintenance services for the National Park Service, Fish and Wildlife Service, and Bureau of Land Management across the continental United States and Hawaii, with Great American Outdoors Act funding supporting deferred-maintenance work. The vendor has issued 43 task orders under parent vehicle 75H70323D00002 (combined potential value $1.7 million). The $5.57 million Indian Health Service single-award 8(a) sole-source IDIQ, established January 13, 2023, and expiring January 11, 2028, covers water and wastewater disposal systems on Native American residences in San Diego, Riverside, and northwest Imperial Counties, California, with delivery orders ranging from approximately $8,700 to $199,500. The newly awarded $249 million Naval Facilities Engineering Command Wet Utilities Construction Projects NAVFAC Southwest Area of Responsibility indefinite delivery contract (December 2024, expiring December 18, 2026) authorizes task orders for new construction and repair of water, steam, wastewater, storm sewer, pumping stations, treatment plants, and storage tanks at federal sites primarily in California, with individual orders ranging $50,000 to $20 million.

Concrete capability examples demonstrate Ama's service portfolio: a $541.2 million delivery order from NAVFAC for repair and protection of potable water storage facilities at Camp Pendleton North (July 2025); a $1.18 million NAVFAC delivery order for potable water storage facility repairs at Camp Pendleton North (June 2025); a $3.3 million Army Corps of Engineers definitive contract for Hopkins Fire debris removal and disposal at Lake Mendocino (January 2023, with subcontractors Fort Bragg Electric and M3 Integrated Services); a $1.35 million U.S. Forest Service delivery order for the Keller Peak Children's Forest Road project in Fawnskin, California (June 2024); a $745.5 million Golden Gate Road and Parking Lot project in Marion County, California (July 2024); and recurring National Park Service task orders for water meter replacement ($127.7 thousand), gate replacement at Fort Point ($470.9 thousand), vault toilet renewal and repainting ($249.9 thousand), and sand relocation at Ocean Beach ($230 thousand to $208 thousand). NAICS concentration spans Water and Sewer Line and Related Structures Construction (59 awards), Commercial and Institutional Building Construction (35 awards), and All Other Specialty Trade Contractors (20 awards). PSC codes align with Construction of Sewage and Waste Facilities (46 awards) and repair or alteration work across recreation facilities, non-building structures, and miscellaneous buildings.

Activity has grown from 8 awards in 2022 to a peak of 29 in 2023, with recent volumes at 16–17 annually (2024–2025). Fifteen awards face ultimate completion within the next twenty-four months with combined potential value of $4.8 million, creating moderate recompete exposure; however, the two large indefinite delivery vehicles (Navy and Interior) provide runway through mid-2027 and beyond, mitigating near-term cliff risk for the core delivery mechanism. SCI-reported invoicing for service contracts above the $150,000 threshold totaled $7.4 million from FY2022 through FY2024, with annual invoicing of $1.5 million (FY2022), $3.6 million (FY2023), and $2.4 million (FY2024), suggesting lumpy project-based revenue. Government-paid hourly rates on SCI-reportable primes ran a median of $428/hr, with senior labor pricing reaching $838/hr at the 90th percentile. Across prime contracts captured in SCI, subcontractors performed an average of 25% of hours; 11 named subs are recorded, including Fort Bragg Electric, Cosco Fire Protection, Wire-Rite, and M3 Integrated Services for specialized electrical and fire protection work—a pattern consistent with Ama's self-perform construction model augmented by trade specialists rather than broad subcontractor reliance.

The vendor's SBA 8(a) certification (which expired January 18, 2023 per the source, though recent awards show continued 8(a) sole-source and competitive 8(a) participation, suggesting possible recertification or ongoing eligibility) is the cornerstone of its federal positioning. All recent awards carry either Total Small Business or 8(a) sole-source set-asides, confirming that Ama competes predominantly within protected categories and has not developed a footprint in full-and-open competition. This set-aside dependency is both a strength (consistent access to vehicles and preferences) and a structural ceiling (no exposure to unrestricted competition against larger, diversified contractors). The vendor's operational footprint is California-heavy, with task orders concentrated in the Pacific West Region, Northern California, and Southern California tribal lands, though the NAVFAC and Interior IDIQs authorize nationwide performance across CONUS, Hawaii, and federal lands. Federal customer concentration outside the National Park Service remains modest; deep diversification would require competitive expansion into other agency customer sets and non-set-aside work.
