Stone Group Architects, Inc.

Stone Group Architects, Inc., a Service-Disabled Veteran-Owned Small Business headquartered in Sioux Falls, South Dakota, delivers architectural and engineering design services to federal agencies as a prime contractor exclusively — 100% of recent awards carry prime responsibility, with zero subcontract activity in the source portfolio. The firm competes predominantly under SDVOSB and Total Small Business set-asides across a healthcare-focused federal practice, supplemented by three named subsidiaries: M Plus Stone HFG LLC, Stone HFG Architecture LLC, and Stone HFG Architecture JV LLC, each carrying SDVOSB and veteran-owned designations.

Stone Group's customer base concentrates overwhelmingly on the Department of Veterans Affairs. The top five funding agencies account for 92% of recent awards by count: Veterans Integrated Service Network 23 leads with 31 awards ($32.7 million combined potential value), followed closely by VISN 12 (30 awards, $18.4 million), VISN 15 (8 awards, $6.5 million), U.S. Air Force Global Strike Command (4 awards, $5.1 million), and Indian Health Service (3 awards, $10.5 million). By potential value, however, the Department of Interior Fish and Wildlife Service Region 9 Headquarters anchors the portfolio with a single $50 million IDIQ awarded September 21, 2022, for architectural and engineering services across federal lands managed by Fish and Wildlife, National Park Service, Bureau of Land Management, and Forest Service. The VA's VISNs collectively dominate: VISN 23 and VISN 12 together account for approximately $51.1 million of the combined portfolio.

Stone Group's capability footprint is grounded in healthcare facility modernization and infrastructure design. Representative work includes a $1.162 million SDVOSB definitive contract awarded October 9, 2026 for behavioral health facility renovation design at Harry S Truman Veterans' Memorial Hospital in Columbia, Missouri (ultimate completion October 9, 2031); a $3.4 million SDVOSB contract awarded October 1, 2026 for infrastructure drawing updates across eight VA medical centers in Kansas, Missouri, and Illinois, including fire protection engineering, life safety design, and Building Information Modeling; a $689 thousand delivery order for asbestos abatement design at Tomah VA Medical Center (awarded June 30, 2023); a $587.8 thousand Total Small Business delivery order for munitions consolidation renovation and design at Ellsworth Air Force Base (awarded April 16, 2025); and a $253.8 thousand task order for shop remodel design in Minneapolis under the DOI Fish and Wildlife MATOC (awarded April 6, 2026). Work spans radiology renovations, catheterization laboratory design, behavioral health clinics, electrical system upgrades, structural repairs, and facility life-safety modernization.

Stone Group holds five named IDIQ vehicles spanning $125.4 million in combined ceiling value. The largest are the $50 million DOI Fish and Wildlife MATOC (single-award, Total Small Business, through September 30, 2027), a $10 million Indian Health Service nationwide architect-engineering IDIQ (single-award, Total Small Business, through March 6, 2027), a $6 million VISN 12 single-award for Tomah VA Medical Center design (SDVOSB, through September 14, 2027), a $5 million VISN 12 single-award for William S. Middleton VA Hospital in Madison (SDVOSB, through September 11, 2027), and a $4.5 million Air Force Global Strike Command multiple-award contract for architect-engineering design and investigation (Total Small Business, through September 11, 2028). Delivery-order activity under the two largest VISN 12 contracts — 36C26319D0058 (Middleton) and 36C25222D0057 (Tomah) — totals 37 task orders worth approximately $13.2 million combined potential value. Within the top five parent vehicles, these two VA contracts alone represent 65% of the task-order count.

Activity trajectory shows contraction: Stone Group recorded 16 awards in 2022, peaked at 21 in 2023, then declined to 12 in 2024, 7 in 2025, and 9 year-to-date in 2026. This downturn is partially offset by the pipeline: 19 awards (combined potential value $10.3 million) reach ultimate completion within the next twenty-four months, presenting material recompete exposure — primarily smaller delivery orders across VISN-managed contracts. The firm's most recent award, dated October 9, 2026, suggests continued VA engagement but at reduced velocity compared to 2023 peak.

SCI-reported invoicing provides a partial snapshot of federal service-contract activity: the firm reported $3.9 million across FY2023–FY2024 ($2 million in FY2023 on 3.9 FTEs, $1.9 million in FY2024 on 19.1 FTEs), with no invoicing reported in FY2022 or FY2025. This narrow capture reflects SCI's $150,000 reporting threshold; SCI data exclude goods, products, and the bulk of architectural design deliverables. On federal service contracts captured in SCI, government-paid rates ran median around $185.95 per hour, with senior labor pricing through $413.20 per hour; across SCI-reportable prime contracts, an average of 13% of contractor hours were performed by subcontractors, with 15 named subs reported across the portfolio.

Stone Group operates exclusively as a prime contractor in the source portfolio — no subcontract work appears under other primes — meaning the firm builds and manages its own delivery teams and does not function as a feeder to larger integrators. Primary NAICS concentration sits at 541310 (Architectural Services, 47 awards) and 541330 (Engineering Services, 36 awards), with PSC code C1DA (Architect and Engineering-Construction: Hospitals and Infirmaries) dominating 65 of 83 awards. The firm's work is concentrated in the Midwest and Southern United States, with heavy activity in Wisconsin (Middleton and Tomah VA centers), South Dakota (Sioux Falls, Hot Springs), Missouri (Columbia), and multi-state healthcare infrastructure projects.
