Henry Adams, LLC

Henry Adams, LLC, a Towson, Maryland-based limited liability company, delivers mechanical, electrical, and plumbing engineering, architectural design, and construction administration services to civilian federal agencies as a prime contractor on 98% of its recent awards, competing predominantly under full-and-open procurements with no recurrent small business set-aside designations despite holding several total-small-business IDV vehicles.

The vendor's concrete capability portfolio centers on facility infrastructure engineering and renovation support: MEP design and engineering studies, construction administration for system replacements and upgrades, facility assessments, energy conservation studies, and architectural and engineering services for federal buildings and infrastructure projects. Representative prime work includes a $50 million indefinite delivery contract from the Department of the Interior Fish and Wildlife Service for architectural and engineering services supporting Department of Interior and Forest Service properties under the Great American Outdoors Act (awarded September 2022, total small business set-aside, through September 2027); a $7.75 million MEP architecture and engineering IDC from the National Institute of Standards and Technology for Gaithersburg campus facilities (total small business set-aside, through August 2026); a $3.3 million A/E IDIQ from the National Oceanic and Atmospheric Administration's Eastern Region for federal facility support (total small business set-aside, through January 2027); and a $1.6 million architect and engineering MATOC from the Bureau of Engraving and Printing for DC facilities upgrades (August 2021, through August 2026). Recent task-order activity includes a $410 thousand firm fixed-price award from the Department of Veterans Affairs for generator replacement and construction administration at the Philadelphia Information Technology Center (September 2024, through December 2027), a $234 thousand NOAA delivery order for post-construction services and construction management of National Hurricane Center facility renovations in Miami, Florida (September 2025, through September 2026), and a $129 thousand GSA definitive contract for service elevator design refresh and construction administration at the James Byrne U.S. Courthouse in Philadelphia (June 2026, through January 2028).

Customer concentration reflects a civilian agency focus across multiple departments, though ranking divergence signals vehicle-driven revenue concentration. By award count, the top five customers account for 67% of awards: the Department of the Army (66 awards), GSA Public Buildings Service Region 3 (50 awards, $23.9 million combined potential value), the Social Security Administration (28 awards, $2.9 million), the Department of Health and Human Services National Institutes of Health Construction (17 awards), and the Department of the Navy (14 awards). By potential value, the ranking shifts: HHS NIH Construction leads at $25.7 million across 17 awards, followed by GSA Region 3 at $23.9 million, NIST at $8 million across four awards, the Department of Veterans Affairs Veterans Health Administration VISN 5 at $5.6 million across six awards, and NOAA at $3.9 million across three awards. The top five customers by potential value account for 53% of combined potential value.

Henry Adams holds four principal IDV vehicles: a GSA indefinite delivery contract (GS03P17DXD0001) carrying 83 task orders worth $10.8 million in combined potential value; an HHS IDC (HHSN292201100026I) with 25 task orders and $4.3 million potential value; and two Army IDCs (DACA3185D0055 with nine task orders and DACA3189D0013 and DACA3192D0030 each with eight task orders). The GSA and HHS vehicles anchor the vendor's recurring revenue pipeline.

Activity has remained relatively flat and low-volume in recent years: 12 awards in 2022, declining to five in 2023, five in 2024, two in 2025, and one in 2026 through mid-year. Only five awards carrying $842 thousand in combined potential value face ultimate completion within the next twenty-four months, presenting minimal recompete exposure over that window. Across the full 262-award historical footprint dating to 1981, combined potential value stands at $126.2 million with $26.3 million obligated (21% utilization rate), reflecting a portfolio of many small task orders under long-standing IDV relationships.

SCI-reported service-contract invoicing shows $914 thousand across FY2022–FY2024 (FY2022: $240 thousand across 0.4 FTEs; FY2023: $0; FY2024: $674 thousand across 1.9 FTEs), representing a narrow slice of the vendor's federal services activity and a smaller subset of total enterprise revenue. Government-paid hourly rates on SCI-reportable prime contracts ranged from $162.72 at the 10th percentile to $165.47 median to $260.66 at the 90th percentile. Across SCI-reportable prime contracts, subcontractors performed an average of 43% of total contractor hours, with 20 named subcontractors reported, signaling a model in which Henry Adams primes the MEP and architectural design scope while bringing in specialized subs for cost estimating, hazardous materials assessment, and complementary design disciplines. Named subcontractors in recent work include Rider Levett Bucknall LTD (cost estimating), Apex Companies LLC (hazardous materials services), Delta Engineers Architects Land Surveyors & Landscape Architects DPC (architectural design), and Woods Peacock Engineering Consultants. Henry Adams also subcontracts selectively under larger architect-engineer primes; recent sub work under Mills and Schnoering Architects PC covers MEP and fire-protection consulting for the Byrne Federal Courthouse hardening design (May 2023) and ICE HSI Forensics Laboratory (May 2022). The vendor's prime vs. sub split and sub-engagement posture reflect a general contractor and MEP consultant positioning: it primes the majority of its own scope, layers on specialized subcontractor expertise where needed, and feeds into larger architectural firms on design-heavy projects.

NAICS concentration in the portfolio reflects the MEP and architectural focus: 114 awards under Engineering Services, 36 under Architectural Services, with one under Commercial and Institutional Building Construction. PSC coding shows the majority under Architect and Engineering–Construction (Office Buildings) with 84 awards and Architect and Engineering–General (Other) with 75 awards, confirming the federal building and infrastructure renovation market as the core customer segment.
