About the company
Ama Diversified Construction Group, a Petaluma, California-based Hispanic American-owned, SBA 8(a) certified small business, operates as a prime contractor on federal construction, infrastructure repair, and water-utilities projects, competing predominantly under Total Small Business and 8(a) sole-source set-asides across civilian and defense agencies. The company holds four active indefinite-delivery vehicles totaling approximately $555 million in combined ceiling value and has delivered 216 prime awards since 2011, with recent activity concentrated in National Park Service facilities maintenance, water and wastewater infrastructure on Native American lands, and potable water systems at military installations.
The vendor's customer concentration is split between National Park Service Pacific West Region (101 awards, $73.4 million combined potential value) and Naval Facilities Engineering Command (7 awards, $257.5 million combined potential value). The NPS Pacific West Region dominates by award count—accounting for 81% of awards across the top five customer agencies—but NAVFAC anchors the dollars through a single $249 million Wet Utilities Construction Projects IDIQ awarded December 19, 2024, set aside for Total Small Business. The Department of Health and Human Services Indian Health Service ranks third by count (46 awards, $7.3 million potential value) and represents sustained work on water and wastewater infrastructure for tribal communities across southern California.
The vendor's primary vehicle portfolio consists of a $250 million Department of the Interior Multiple-Award Task Order Contract (MATOC) for construction, alteration, repair, and maintenance across DOI agencies nationwide (awarded January 1, 2022, expiring June 30, 2027); a $5.57 million Indian Health Service single-award 8(a) sole-source IDIQ for water and wastewater systems on Native American residences in San Diego, Riverside, and northwest Imperial Counties, California (awarded January 13, 2023, expiring January 11, 2028); a $249 million Naval Facilities Engineering Command (NAVFAC) Southwest Area of Responsibility wet utilities construction IDIQ (awarded December 19, 2024, completing December 18, 2026); and a $45 million National Park Service Pacific West Region multiple-award facilities construction IDIQ (awarded February 19, 2026, expiring February 18, 2031). Representative task-order work under these vehicles includes $497,108 for vapor barrier installation at Capehart Housing in Sausalito under the DOI MATOC; $541,198.62 for potable water storage facility repairs at Camp Pendleton North under NAVFAC (awarded July 10, 2025); $1.184 million for potable water storage repairs at Camp Pendleton North under NAVFAC (awarded June 24, 2025, completing October 2, 2026); $1.347 million for Keller Peak Children's Forest Road infrastructure under U.S. Forest Service Region 5, Pacific Southwest Region (awarded June 3, 2024, funded under the Inflation Reduction and Jobs Act); and numerous Indian Health Service delivery orders for individual residential water, septic, and wastewater systems ranging from approximately $4,380 to $199,500.
Activity has grown unevenly over recent years—from 8 awards in 2022 to 29 in 2023, declining to 17 in 2024, then stabilizing at 16 in 2025 and 18 in 2026. Thirteen awards carrying $3.5 million in combined potential value face ultimate completion within the next twenty-four months, presenting recompete exposure concentrated in Indian Health Service water-infrastructure task orders. The vendor's NAICS and PSC footprint centers on construction of sewage and waste facilities (48 awards), water and sewer line construction (61 awards primary NAICS), and repair and alteration of non-building facilities, reflecting its specialization in utilities and infrastructure rather than general building construction.
SCI-reported invoicing of federal service contracts above the $150,000 threshold totaled $9.5 million across FY2022–FY2025, with peak activity in FY2023 at $3.6 million. The dataset shows roughly 2.0 FTEs delivered in FY2022, declining to 0.5 FTEs in FY2025, indicating that SCI-captured labor is a small subset of the vendor's project-based construction delivery model. On federal services contracts captured in SCI, median government-paid rates ran around $446.96 per hour, with senior labor pricing through approximately $821.81 per hour and entry-level labor starting near $165.02 per hour. Across SCI-reportable prime contracts, an average of 26% of contractor hours were performed by named subcontractors, with 12 total named subcontractors identified—including Wire-Rite, Inc. for electrical services and Cosco Fire Protection, Inc. for fire protection system work on Edwards Air Force Base projects, and Fort Bragg Electric, Inc. for wellhouse power infrastructure supporting water treatment operations in Ukiah. The vendor operates primarily as a prime contractor with selective subcontractor relationships rather than as a feeder to larger primes.
The vendor's capability portfolio is grounded in concrete infrastructure delivery: water meter replacement with lead-free ultrasonic meters at Golden Gate National Recreation Area ($384,531 and $127,678 in separate 2026 awards under total small business); vault toilet renewal and repainting at 15 Golden Gate locations ($249,926, September 2025); guardrail replacement on Marine Drive in San Francisco ($264,601.67, September 2023); gate replacement at Fort Point and Golden Gate National Recreation Area ($470,932.01, June 2024, extended through December 2025); deck and roof repairs at Muir Woods Superintendent's Residence ($134,221, August 2025); sand relocation and beach maintenance at Ocean Beach in San Francisco ($230,043 and $208,017 in separate 2023 and 2024 awards); potable water storage facility repair and protection at military installations ($541,198.62 at Camp Pendleton, July 2025); wastewater treatment plant repairs and water booster pump repairs at Edwards Air Force Base ($354,764.79 and $1.849 million, both September 2023); and sustained delivery of individual residential water, septic, and wastewater systems on tribal lands for the Indian Health Service. These awards span firm-fixed-price purchase orders, definitive contracts, and delivery orders under parent IDIQs. The vendor does not hold positions on government-wide acquisition contracts or GSA Schedules and competes through agency-specific vehicles and direct awards set aside for small business.
