Hammel Green & Abrahamson Inc.

Hammel Green & Abrahamson Inc., doing business as HGA Architects and Engineers, is a Minneapolis-based national multidisciplinary architectural and engineering firm that operates exclusively as a prime contractor on federal facility design, renovation, and technical assessment projects across civilian agencies, with no reliance on small business set-asides. HGA was founded in 1953 and competes on a full-and-open basis, delivering services across 27 federal customer agencies with a footprint of 303 total awards worth $249.4 million in combined potential value.

HGA's capability portfolio centers on architectural and engineering services for federal real property: facility design and modernization, feasibility studies, construction administration and inspection, building system assessments, and technical studies supporting repair and alteration of federal buildings. Representative work includes a $2.496 million architect-engineer design study for the Grand Portage Land Port of Entry in Minnesota (GSA Region 5, awarded August 2022), a $814 thousand ventilation verification survey across four federal buildings in the upper Midwest under the CARES Act program (GSA Region 5, awarded March 2024), and a $425 thousand courthouse hardening project with architect-engineer services at the Milwaukee Federal Building & U.S. Courthouse (Administrative Office of the U.S. Courts, awarded October 2023). Recent 2026 delivery orders demonstrate sustained capability across courthouse modernization, facility infrastructure upgrades, and specialized technical work: a $480 thousand USCIS security upgrade design at 250 Marquette Avenue in Minneapolis (DHS, August 2026), a $342 thousand design order for U.S. Courthouse chambers in Madison, Wisconsin (Administrative Office of the U.S. Courts, August 2026), and a $261 thousand switchgear replacement design at the Milwaukee Federal Building (GSA Region 5, April 2026).

Customer concentration is heavily skewed to GSA's regional operations. The top five customer agencies by award count represent 72% of recent awards. GSA Public Buildings Service Region 5 dominates both volume and dollars—139 awards worth $71.2 million combined potential value—reflecting HGA's entrenched position in the upper Midwest federal real estate footprint (Minnesota, Wisconsin, Michigan). The Department of Homeland Security Customs and Border Protection ranks second by potential value ($66.5 million across 8 awards, primarily land port of entry work), while the Department of Veterans Affairs (33 awards), GSA Public Buildings Service broad (32 awards, $955 thousand), and the Administrative Office of the U.S. Courts (7 awards, $1.4 million) round out the active set. The two rankings track closely—GSA Region 5 leads in both metrics—with Social Security Administration placing three awards worth $15.4 million, signaling diversification beyond courthouse and federal building maintenance.

HGA holds a primary vehicle: the GSA Public Buildings Service Region 5 Indefinite Delivery Contract 47PF0019D0038 ($10 million, awarded January 16, 2025, through January 15, 2027), which has generated 76 task orders worth $8.7 million combined potential value since inception. This is the vendor's anchor vehicle, covering architectural and engineering services for repair and alteration projects across the three-state region, with most projects sized between $50,000 and $500,000 in construction costs. Legacy vehicles include Indefinite Delivery Contract GS05P00GAD0138 (33 task orders, $198 thousand), the 2016-2021 MN WI Service Center Architect Engineering vehicle (33 task orders, $1 million), and Indefinite Delivery Contract GS05P10SAD0021 (28 task orders, $2 million). All recent delivery orders are firm fixed price with no set-aside designation, reflecting HGA's full-and-open competitive posture.

Activity has been volatile across the source window. Awards per year ranged from 5 (2025) to 19 (2023), with 18 awards in 2026 reflecting uptick in the past eight months. Thirteen awards with ultimate completion dates in the next twenty-four months carry $2.3 million in combined potential value, presenting modest recompete exposure relative to the vendor's $249 million portfolio. The relatively small near-term cliff reflects a portfolio weighted toward completed and dispersed delivery orders rather than concentration in large multi-year prime contracts.

HGA operates as a pure prime contractor across its federal footprint: 302 of 303 awards (100% of portfolio) are prime awards; only one sub-award appears in the source, a December 2025 architectural services sub to Valkyrie Enterprises for Department of Defense line funding. This prime-heavy posture indicates HGA builds and deploys its own delivery teams rather than functioning as a feeder to larger prime contractors.

Service Contract Inventory data (covering federal service contracts above $150,000 reporting threshold) shows SCI-reportable invoiced revenue of $14.8 million across 17 records spanning FY2022–FY2025. HGA invoiced $11.5 million in FY2022 (19.6 FTEs reported), dropped to zero SCI-reportable invoicing in FY2023, rebounded to $3.3 million in FY2024 (5.1 FTEs), and declined again in FY2025 (2.9 FTEs across 4 records). The SCI dataset captures only a partial view of HGA's federal services activity and excludes its substantial goods and design deliverables work. Government-paid hourly rates on SCI-reportable prime contracts ranged from $192.59/hr at the 10th percentile to $457.76/hr at the 90th percentile, with a median of $297.27/hr, positioning the firm at mid-to-upper market rates consistent with national architectural and engineering practice. Across SCI-reportable prime contracts, the vendor performed 0% of hours through subcontractors, delivering work entirely with internal staff.

NAICS framing reflects architectural and engineering services concentration: 229 awards (75% of portfolio) carry NAICS 541310 (Architectural Services), with 37 awards under NAICS 541330 (Engineering Services). PSC coding follows the same pattern—133 awards under PSC A/E General (Landscaping, Interior Layout, Designing), 56 under A/E Construction Office Buildings, and 20 under A/E General Other, confirming HGA's singular focus on design and assessment services rather than construction, procurement, or operational support. The vendor has not competed for federal construction or systems integration work in the source window.

Corporate structure lists HGA Mid-Atlantic, Inc. as a subsidiary, signaling potential geographic expansion beyond the upper Midwest core, though award data shows minimal East Coast activity.
