G.m. Hill Engineering, Inc.

G.M. Hill Engineering, Inc., doing business as GM Hill Engineering, is an Economically Disadvantaged Women-Owned Small Business (EDWOSB) and SBA 8(a) certified firm that delivers architectural, engineering, construction, and facility maintenance services to federal agencies as a prime contractor (100% of recent awards). Based in Jacksonville, Florida, and structured as a Subchapter S Corporation, GM Hill Engineering operates predominantly under small business set-asides—particularly Total Small Business, Woman-Owned Small Business, and Competitive 8(a) designations—across a portfolio of 291 prime awards with combined potential value of $2.7 billion. The firm maintains two named joint-venture subsidiaries: GMH Baker JV II LLC and Gmh-C JV II, LLC, both certified small disadvantaged women-owned businesses.

GM Hill Engineering's core capability portfolio spans building construction, renovation, repair, and modernization; architect-engineer design and Title II services; facility maintenance and mechanical systems work; and design-build project delivery. Recent representative work includes a $11 million definitive contract with the U.S. Forest Service for design-build reconstruction of the London Ranger District Administrative Site in Kentucky under a Total Small Business set-aside (awarded April 2023, invoiced $5.5 million through FY2025 across 28,279 contractor hours); a $3.16 million firm fixed-price definitive contract with the U.S. Coast Guard to construct a new ANT Storage Building at Coast Guard Station Milford Haven, Virginia (awarded July 2024, Woman-Owned Small Business set-aside); and a $3.02 million 8(a) Sole Source contract with the National Park Service for construction of replacement housing hardened to resist storms and flooding at Everglades National Park, Florida (awarded July 2022). The vendor also holds a $360 million MATOC with the Department of Labor Job Corps for nationwide design-build and construction services (awarded September 2026, Total Small Business set-aside) and a $193 million MAIDIQ with Army Installations Management Command Southeast Region for Fort Benning construction work (awarded July 2026, Total Small Business set-aside).

Customer concentration sits heavily with federal facilities and infrastructure agencies. The top five customers by award count account for 53% of recent awards, led by the Department of Justice Bureau of Prisons Central Office (88 awards, $61.7 million potential value) and the U.S. Coast Guard (26 awards, $69.3 million potential value). By dollar potential, concentration is more pronounced in IDIQ and MATOC vehicles: the Department of Interior Fish and Wildlife Service Region 9 anchors three awards valued at $550 million combined, the Army Corps of Engineers holds multiple awards totaling $252.9 million across districts, and IMCOM Southeast Region's Fort Benning MAIDIQ carries $193.1 million. The disparity between award-count and dollar-value rankings reflects GM Hill Engineering's strength in larger indefinite-delivery vehicles alongside high-frequency task-order activity at the Bureau of Prisons for routine facility maintenance.

Parent vehicles dominate the delivery landscape. GM Hill Engineering holds seats on multiple significant IDIQs and MATOCs, including the OASIS+ SBA-Certified Women-Owned Small Business multiple-award GWAC with GSA (no ceiling specified in source, June 2025 award, performance through June 2030); a $99 million single-award IDC with the Army Corps of Engineers Savannah District for general construction and design-build services (awarded November 2024); a $50 million single-award Coast Guard RMACC Bridge contract (awarded July 2024, Total Small Business set-aside); a $250 million multiple-award MATOC with Interior Fish and Wildlife Service for design-build construction under the Great American Outdoors Act (March 2023 award); a $116.4 million Vertical Construction MATOC with Army Corps Engineering District Fort Worth for design-build and design-bid-build services (September 2023 award, Woman-Owned Small Business set-aside); and a $23 million single-award IDC with the Environmental Protection Agency for strategic planning, space analysis, and project management services (September 2023, Total Small Business set-aside). Among task-order-producing vehicles, IDC N4008518D0632 shows 15 task orders worth $16.4 million combined, and IDC W912HN20D4006 carries 14 task orders valued at $33.5 million combined. The $4.5 million TSA architect-engineering consulting contract (8(a) sole-source, September 2023 award) represents a focused single-award vehicle.

Activity has contracted sharply in recent years. Awards per year declined from 42 in 2023 and 26 in 2022 to 17 in 2024, 8 in 2025, and 12 in 2026 year-to-date. Ten awards carrying combined potential value of $17.9 million reach ultimate completion within the next twenty-four months, signaling moderate recompete exposure for the vendor and competitive opportunity for others on these delivery orders as they renew or re-task. The vendor operates virtually exclusively as a prime contractor—only one sub-award appears in the source portfolio (a sub role under CDM Federal Programs Corporation on the Atlanta Job Corps Center design, awarded August 2024). The distinction between prime vs. sub posture and significant IDIQ holdings suggest GM Hill Engineering built its business model around prime contracting under set-aside vehicles rather than feeding larger primes.

SCI-reported invoiced revenue on federal service contracts above the $150,000 threshold totaled $39.6 million across FY2022–FY2025, representing a narrow slice of the vendor's total federal business. FY2022 invoicing reached $10.9 million across 15.3 FTEs; FY2023 was $12.1 million (16.1 FTEs); FY2024 declined to $6.1 million (13.2 FTEs); and FY2025 recovered to $10.5 million (17.5 FTEs). The FTE trajectory shows volatility, ranging 10.2 to 16.1 FTEs across the four-year window—likely reflecting the project-based and task-order-driven nature of construction and engineering services. Hourly-rate posture on SCI-reportable prime contracts shows a median of $245.30 per hour, with the 10th percentile at $0.00 per hour (probable floor-pricing or minimum-guarantee lines) and the 90th percentile at $837.24 per hour, indicating a broad rate spectrum spanning junior labor, project management, and senior engineering roles. Across SCI-reportable prime contracts, subcontractors accounted for an average of 12% of total contractor hours, with 31 named subcontractors appearing across the contracts—indicating GM Hill Engineering performs the majority of work in-house but engages specialized subs for defined scope elements. The London Ranger District contract exemplifies this posture: in FY2025, seven subcontractors performed 57% of contractor hours on that single scope, reflecting deep teaming on a complex, multi-disciplinary design-build project.

The category concentration underscores GM Hill Engineering's construction-first identity. Of 292 total awards, 121 carry NAICS 236220 (Commercial and Institutional Building Construction), 47 use 541330 (Engineering Services), and 43 cite 238900 (Facilities Support Services). PSC codes align: Maintenance of Office Buildings (38 awards), Construction of Miscellaneous Buildings (28 awards), and Repair or Alteration of Office Buildings (27 awards) dominate the listing. This concentration—spanning Department of Justice, Coast Guard, Army Corps, Marine Corps, Air Force, Interior, EPA, and TSA—reflects a vendor optimized for federal real property and infrastructure improvement across military installations and civilian facilities. The 8(a) and EDWOSB posture, combined with the Total Small Business set-aside concentration, positions GM Hill Engineering as a primary vehicle for federal agencies seeking certified small disadvantaged women-owned capacity for mid-sized construction and design-build work in the $500 thousand to $50 million delivery order range.
