Henry Adams, LLC

Henry Adams, LLC, a Towson, Maryland–based architecture and engineering services firm, operates as a prime contractor (98% of recent awards) delivering mechanical, electrical, and plumbing engineering design, architectural design, facility assessments, energy conservation studies, and construction administration services to civilian federal agencies under total small business set-aside vehicles and full-and-open competition. The vendor competes across both procurement channels, with the majority of recent activity concentrated in small-business-set-aside delivery orders and task orders under indefinite delivery contracts.

Henry Adams' customer base is dispersed across 28 federal agencies. The top five customers by award count and potential value diverge somewhat: the Department of the Army leads by volume (66 awards), followed by GSA Public Buildings Service Region 3 (50 awards, $23.9 million combined potential value) and the Social Security Administration (28 awards, $2.9 million combined potential value). By dollar concentration, the top tier includes the Department of Health and Human Services National Institutes of Health Construction (17 awards, $25.7 million combined potential value), GSA Public Buildings Service Region 3, and the Department of Commerce National Institute of Standards and Technology (4 awards, $8 million combined potential value). These five customer agencies account for 53% of combined potential value across the portfolio. The vendor's work spans office building design and engineering, miscellaneous building construction support, and landscaping and interior layout services — 117 awards in Engineering Services NAICS, 36 in Architectural Services — with geographic concentration in the Mid-Atlantic and federal facilities nationwide.

Henry Adams' most significant vehicle holding is an indefinite delivery contract under GSA (GS03P17DXD0001) carrying 83 task orders worth $10.8 million in combined potential value. The vendor also holds a $50 million Department of Interior Fish and Wildlife Service multiple-award MATOC (Architecture and Engineering Services 2022–2027) under total small business set-aside, running through September 2027, where recent deliveries include a $525,764 Department of Veterans Affairs delivery order for generator replacement and construction administration at the Philadelphia Information Technology Center (September 2024 through July 2028), a $234,284 NOAA delivery order for post-construction services at the National Hurricane Center facility in Miami (completed September 2026), and a $296,441 NOAA delivery order for electrical upgrade specification development at the Atlantic Oceanographic and Meteorological Laboratory (September 2026 through March 2027). Henry Adams holds additional IDCs through the Department of the Army and Department of Health and Human Services, with 25 task orders under HHSN292201100026I ($4.3 million combined potential value). Only seven awards face ultimate completion within the next twenty-four months, carrying combined potential value of $1.5 million, indicating limited near-term recompete exposure.

Activity has declined year over year — 12 awards in 2022 declining to 2 in 2025 and 5 through mid-2026 — reflecting a shift in the portfolio from higher historical volume. Service Contract Inventory data shows minimal federal service-contract invoicing above the $150,000 threshold: $240 thousand in FY2022, no reportable invoicing in FY2023, and $674 thousand each in FY2024 and FY2025, spanning roughly 0.1 to 1.9 FTEs. On SCI-reportable prime contracts, median government-paid hourly rates run around $197/hr, with senior labor pricing through $268/hr and entry-level work from $163/hr, indicating mid-tier professional labor positioning. Across prime contracts captured in SCI, subcontractors account for an average of 43% of total contractor hours, with 26 named subcontractors appearing across the vendor's portfolio, including Rider Levett Bucknall LTD (cost estimating), Apex Companies LLC (industrial hygiene and hazardous materials), Delta Engineers, Architects, Land Surveyors & Landscape Architects D.P.C. (architectural services and mechanical systems design), GHD Inc. (IT and security design), and Woods Peacock Engineering Consultants Inc., a women-owned small business providing structural engineering. The vendor also subcontracts to prime contractor Mills and Schnoering Architects on MEP services for federal courthouse hardening and forensic laboratory design.
