G.m. Hill Engineering, Inc.

G.M. Hill Engineering, Inc., doing business as GM Hill Engineering, is a Jacksonville, Florida-based Economically Disadvantaged Women-Owned Small Business (EDWOSB) and SBA 8(a) certified firm that delivers architectural, engineering, construction, and facility maintenance services to the federal government as a prime contractor (100% of recent awards). The company competes predominantly through set-aside vehicles — 8(a) Sole Source, Competitive 8(a), Total Small Business, and Woman-Owned Small Business designations dominate the portfolio — though substantial work also flows through full-and-open delivery orders and definitive contracts on larger IDIQs.

GM Hill Engineering operates a substantial federal contracting footprint spanning 287 awards (286 prime, 1 sub) worth $2.15 billion in combined potential value, though dollars obligated stand at only $260.8 million (12% of potential value), indicating many awards are indefinite delivery vehicles with task orders flowing over multiple years. The award trajectory shows concentration in 2022–2023 (26 and 42 awards respectively) with tighter output in 2024–2026 (17, 8, and 7 awards), suggesting activity is cyclical and tied to IDV option exercise and new vehicle wins. Ten awards with ultimate completion dates in the next twenty-four months carry $21.6 million in combined potential value and face recompete.

Customer concentration is acute. The Department of Justice Bureau of Prisons Central Office represents 88 awards (31% of total count) worth $61.7 million, anchoring the portfolio with recurring facility maintenance, LED upgrades, interior demolition, and office moving contracts. The U.S. Coast Guard accounts for 26 awards ($69.3 million) across repair, maintenance, and construction services under the Coast Guard RMACC 2019 and D7 RMACC Bridge Contract vehicles. The Army Corps of Engineers Savannah District dominates potential-value rankings with 18 awards ($227.5 million), driven by a $99 million single-award general construction and design-build IDC (W912HN25D4007) awarded November 2024. The top five customers account for 54% of award count and 56% of combined potential value; the Interior Fish and Wildlife Service Region 9 carries disproportionate value ($550 million across 3 awards) through design-build and architecture-engineering MATOC vehicles.

GM Hill's vehicle position spans eleven active indefinite delivery contracts. The largest is the OASIS+ SBA-Certified Women-Owned Small Business IDIQ with the General Services Administration, awarded June 2025, carrying a multi-billion-dollar ceiling and serving as a government-wide vehicle for comprehensive integrated professional services. Two Department of Interior design-build MATOCs valued at $250 million (Fish and Wildlife Service, March 2023) and $50 million (Architecture and Engineering Services, September 2022) provide work for facility improvements and infrastructure repair across federal lands. A $116.4 million Vertical Construction MATOC with the Army Corps of Engineers Fort Worth (September 2023) is set aside for Women-Owned Small Businesses. Additional vehicles include a $99 million single-award construction IDC with USACE Savannah District, a $50 million Coast Guard bridge contract (July 2024), a $23 million EPA strategic planning and facilities design contract (September 2023), a $6 million Air Force Materiel Command architect-engineer IDIQ at Warner Robins (June 2022), and a $4 million Transportation Security Administration consulting IDC (September 2023). A $9.9 million Air Education and Training Command architectural-engineering IDIQ was awarded September 2025 for work at Sheppard Air Force Base and supporting installations.

Concrete capability examples include a $1.335 million Competitive 8(a) delivery order (April 2026) for comprehensive repair and renovation of a 70-room, 25,000-square-foot military dormitory at Warner Robins Air Logistics Complex; a $1.614 million Partial Small Business order (April 2026) from the Army Corps of Engineers for military working dog kennel services at Hurlburt Field, Florida; a $2.46 million Total Small Business delivery order (February 2026) from the National Office for design-build sinkhole repair in Washington, DC, under the Great American Outdoor Design Bid Build Construction MATOC; a $17.98 million Woman-Owned Small Business delivery order (June 2023) for the Rapid Applied Materials Laboratory Project Bathroom Demolition in Millington, Tennessee; and a $11.05 million Total Small Business definitive contract (April 2023) with the U.S. Forest Service for design-build reconstruction of the London Ranger District Administrative Site in Kentucky, with LEED Silver certification and net-zero energy objectives, delivering $1.5 million in government-invoiced labor through FY2024 across 4.2 FTEs and 8,786 contractor hours. Recent work encompasses facility renovations, fire alarm and HVAC system replacements, building demolition and rehabilitation, security infrastructure, EV charging installation, roof replacement, and structural assessments across military installations, federal civilian facilities, and civilian agency headquarters.

Service Contract Inventory reporting covers only federal service contracts above the $150,000 threshold and excludes goods, products, and classified work; it shows $29.1 million in SCI-reportable invoiced revenue across 53 prime records from FY2022–FY2024 ($10.9 million FY2022, $12.1 million FY2023, $6.1 million FY2024). The SCI dataset reflects roughly 14.1 FTEs in FY2022, 12.5 FTEs in FY2023, and 11.1 FTEs in FY2024, representing a declining trajectory in the captured subset. Government-paid hourly rates on SCI-reportable prime contracts run a median of $253.63/hr, with 90th percentile rates reaching $812.54/hr, indicating a mix of labor grades from project management and support roles to senior professional services. Across SCI-reportable prime contracts, subcontractors account for an average of 10% of total contractor hours; the vendor names 21 distinct subcontractors in SCI records, suggesting a predominantly self-delivery posture with light subcontractor engagement on specific scopes.

The corporate structure includes two named joint-venture subsidiaries — GMH Baker JV II LLC and Gmh-C JV II, LLC — both certified as Self Certified Small Disadvantaged Businesses and Joint Venture Women Owned Small Businesses. Neither subsidiary appears prominently in the prime awards listings; the parent G.M. Hill Engineering, Inc. dominates the contracting footprint and carries the SBA certifications. The single sub-award in the source (August 2024) is a CDM Federal Programs Corporation prime for full design of the Department of Labor Campus Site in Atlanta, with GM Hill performing consultant services related to demolition and salvage requirements for the Atlanta Job Corps Center.

GM Hill Engineering's category concentration aligns with its facility and infrastructure focus: Commercial and Institutional Building Construction (118 awards), Engineering Services (45 awards), and Facilities Support Services (43 awards) represent the top three NAICS codes. PSC concentration shows Maintenance of Office Buildings (37 awards), Construction of Miscellaneous Buildings (28 awards), and Repair or Alteration of Office Buildings (27 awards) as dominant codes. The vendor operates across 51 distinct customer agencies, reflecting broad federal exposure balanced against deep concentration in a small number of high-volume, recurring mission partners — particularly the Bureau of Prisons' facilities maintenance contracts and the Army Corps of Engineers' construction IDCs.
