Hammel Green & Abrahamson Inc.

Hammel Green & Abrahamson Inc., doing business as HGA Architects And Engineers, is a Minneapolis-headquartered multidisciplinary architectural and engineering design firm that operates as a prime contractor on full-and-open federal facility modernization, design, and technical assessment work, competing without set-aside designations and generating $248.4 million in combined potential value across 299 awards since 1985.

HGA is a for-profit corporation established in 1953 with four named subsidiaries including HGA Mid-Atlantic, Inc. The vendor competes exclusively as a prime contractor (100% of tracked awards), delivering architectural and engineering professional services for federal building repair, alteration, modernization, and feasibility studies across the upper Midwest and nationally. The firm's service portfolio encompasses design development, construction documentation, building system studies, structural assessments, facility improvement initiatives, construction management and inspection, and post-construction support — grounded in a practice centered on federal courthouses, land ports of entry, office buildings, and specialized federal facilities. Representative work includes a $2.496 million design study for the Grand Portage Land Port of Entry in Minnesota, a $425.480 million hardening and architect-engineer services delivery order for the Milwaukee Federal Building & U.S. Courthouse, a $814.322 million ventilation verification survey across four federal buildings in Region 5 under the CARES Act, and a current $10 million regional IDIQ for repair and alteration projects.

Customer concentration is regional and agency-heavy. The top five funding agencies account for 73% of awards by count, led decisively by General Services Administration Public Buildings Service Region 5 (139 awards, $71.2 million combined potential value) and Department of Homeland Security Customs and Border Protection (8 awards, $66.5 million). The GSA Region 5 relationship dominates both volume and dollars — representing 139 delivery orders against the current $10 million IDIQ and a prior indefinite-delivery vehicle — while CBP's concentration reflects a smaller number of higher-value land port of entry projects. Department of Veterans Affairs ranks third by award count (33 awards) but carries lower individual values; Social Security Administration and the Administrative Office of the U.S. Courts round out the active customer base. The vendor has served 27 distinct agencies since 1985.

HGA holds a primary vehicle position on the GSA Public Buildings Service Region 5 $10 million Multiple Award IDIQ (47PF0019D0038), awarded January 16, 2025, running through January 15, 2027, covering architectural and engineering services for repair and alteration projects across Minnesota, Wisconsin, and Michigan with estimated construction costs typically between $50,000 and $500,000. Since inception of this vehicle, HGA has executed nine delivery orders totaling approximately $614,000. The vendor also maintains positions on legacy GSA indefinite-delivery contracts (GS05P00GAD0138 with 33 task orders; GS05P10SAD0021 with 28 task orders) and a prior regional service-center vehicle (MN WI Service Center Architect Engineering 2016–2021 with 33 task orders). All recent delivery orders have been awarded on firm fixed-price terms without set-aside designations, reflecting HGA's competitive standing as a full-scale service provider.

Activity has been uneven. Awards per year show a spike to 19 in 2023, declining to 10 in 2024 and 5 in 2025, then recovering to 14 in 2026 through May. Sixteen awards with ultimate completion dates in the next twenty-four months carry combined potential value of $2.3 million, representing modest recompete exposure. The vendor operates as an exclusively prime contractor, with only one sub-award visible in the dataset (a December 2025 architectural services sub to Valkyrie Enterprises, LLC for DoD line funding).

On SCI-reportable federal service contracts, HGA invoiced $14.8 million across FY2022–FY2024, with $11.5 million in FY2022 (19.6 FTEs) and $3.3 million in FY2024 (5.3 FTEs); FY2023 carried no SCI-reportable invoicing. Median government-paid hourly rates run approximately $297/hr, with the 10th percentile at $193/hr and the 90th percentile at $458/hr, reflecting a mix of junior and senior professional architectural and engineering labor. Across SCI-reportable prime contracts, the vendor performed 0% of hours through subcontractors, indicating a wholly in-house delivery model on captured service contracts.

The vendor's NAICS concentration is 225 awards under Architectural Services (541310) and 37 under Engineering Services (541330), with PSC framing dominated by Architect and Engineering – General (133 awards) and Architect and Engineering – Construction, Office Buildings (52 awards). HGA competes on partial small-business-set-aside IDIQs but wins all visible recent delivery orders on full-and-open terms, positioning it as a capable mid-market A/E firm without reliance on small-business compliance overhead.
