Trivers Associates, Inc.

Trivers Associates, Inc., a small-business-certified St. Louis-based architectural and engineering firm, operates as a 100% prime contractor delivering historic preservation consulting, space planning, interior design, and building deconstruction services to civilian federal agencies, with heavy concentration in GSA Public Buildings Service work under GSA's own contract vehicles and a significant emerging presence under Army Corps of Engineers architecture-engineering frameworks.

Trivers is a for-profit Subchapter S corporation structured as a corporate entity with no SBA 8(a) or other minority-ownership designations. The firm competes predominantly under Total Small Business set-asides (across GSA, Army Corps, Forest Service, and Veterans Affairs work), and on full-and-open civilian agency contracts. Primary NAICS coding aligns with 541620 (Historical Preservation Consulting) and 541410 (Interior Design), with secondary activity in 541310 (Architectural Services) and environmental consulting under R&D codes. The award portfolio spans thirteen distinct customer agencies across 111 awards with a combined potential value of $43.5 million, of which $19.9 million is currently obligated.

Customer concentration heavily favors GSA. The General Services Administration's Public Buildings Service accounts for 68 awards (84% by count, but a smaller share by dollars), distributed across multiple GSA regions. By potential value, however, the top-dollar customers diverge: the Department of the Army's Corps of Engineers Engineering District St. Louis anchors the portfolio with a $20 million ceiling on a Master Architect-Engineer (A-E) Multiple Award IDIQContract running through January 28, 2031, awarded January 29, 2026. GSA Region 5 (Great Lakes area) carries $9.6 million across three awards under an indefinite-delivery space planning and interior design contract. Department of Veterans Affairs Veterans Integrated Service Network 15 holds $5.1 million across three awards. GSA Region 7 and Region 4 round out the top-five customers by potential value. The distinction between award count and dollar concentration signals that Trivers executes many small consulting engagements through GSA's nationwide PBS infrastructure while anchoring future revenue growth to the newer and much larger USACE A-E vehicle.

Trivers' core vehicle portfolio consists of five active IDV and BPA frameworks. The USACE St. Louis District Master A-E contract (W912P926DA030, $20 million ceiling, January 2026 – January 2031) is the largest and most recently awarded, establishing a nationwide architecture-engineering vehicle for miscellaneous civil and military works design and historic preservation services. GSA Region 5's space planning and interior design IDIQ (September 2024 – September 2029, $500,000 ceiling) covers the Great Lakes region (Illinois, Indiana, Michigan, Minnesota, Ohio, Wisconsin). A GSA Federal Supply Schedule contract (December 2024 – December 2029, $1 million ceiling) under Special Item Number 541620 provides broad multi-agency access to Trivers' architectural and historic preservation labor categories. The Forest Service Region 9 Blanket Purchase Agreement for historic preservation services ($900,000 ceiling, February 2023 – February 2028) has generated multiple task orders for feasibility studies and historic structures reports. A third unnamed indefinite-delivery contract (NMA40297D7002) has generated eight task orders and represents Trivers' oldest active vehicle. One award reaching completion within the next twenty-four months carries only $79,000 in potential value, indicating minimal recompete exposure in the near term.

Recent representative work includes a $20 million Army Corps of Engineers Master A-E contract (January 2026, Total Small Business set-aside) establishing nationwide capabilities for architectural and engineering services; a $79,198 Forest Service Region 9 firm fixed-price BPA call (September 2025, Total Small Business) for a feasibility study and future-use plan for the J.W. Toumey Historic District buildings in Watersmeet, Michigan (completion August 2026); and a $2,500 Department of Defense delivery order (February 2026, Total Small Business) for architectural and engineering services under an MATOC structure (with ultimate completion January 2031, though the minimal obligation suggests task order sequencing). Earlier engagements include a $60,000 GSA Public Buildings Service definitive contract for a building deconstruction study of the Moakley Courthouse in Boston (July 2022 – December 2023) and a $44,482 Forest Service purchase order for a historic structures report on the DM & IR Section House near Isabella, Minnesota (April 2023, completed August 2023).

Trivers' GSA Schedule labor offering spans eleven categories from Interior Designer ($85.67/hr, bachelor's degree, zero years experience required) through Senior Historic Architect ($234.96/hr, bachelor's degree, ten years experience required), with mid-spectrum positions including Project Manager ($209.96/hr) and Architect Level III ($169.96/hr). No security-cleared positions are offered. The schedule covers architecture, historic structures documentation and evaluation, project management, and interior design, with work performed worldwide under St. Louis administrative coordination.

Service Contract Inventory data (which captures federal service contracts above the $150,000 reporting threshold) shows Trivers reported $4.7 million in invoiced prime-contract revenue across FY2022–FY2024, with marked decline: $3.5 million in FY2022 across 5.3 FTEs, $897,000 in FY2023 across 2.0 FTEs, and $375,000 in FY2024 across 0.7 FTEs. The SCI dataset represents a partial view of Trivers' federal services activity and a smaller share of total enterprise revenue. Government-paid hourly rates on SCI prime contracts ranged from $211.32/hr at the tenth percentile to a median of $268.77/hr and $515.08/hr at the ninety-percentile, reflecting senior technical and project-management labor. Trivers operates as its own delivery team: across SCI-reportable prime contracts, 95% of contractor hours were performed by Trivers staff, with only one named subcontractor reported.

Recent activity has flattened. The five-year award trajectory shows two awards in each of 2022, 2023, and 2024, with one award in 2025 and two in 2026 year-to-date, indicating stable but not accelerating volume outside the large USACE and GSA vehicles recently established.
