About Rimkus Consulting Group, Inc.
Rimkus Consulting Group, Inc., a Houston-based for-profit limited liability company, provides expert witness services and forensic engineering consultation to federal agencies as a prime contractor on unrestricted (full-and-open) procurement. The vendor competes exclusively without set-aside designations across its federal footprint and operates as a pure prime — all 147 recent awards are prime contracts or IDVs with no subcontractor role.
The vendor's core capability is expert witness testimony and technical analysis in biomechanical engineering, construction forensics, and related engineering disciplines. Representative work includes a $488,000 time-and-materials purchase order from the Department of Justice Civil Division for expert witness services running through June 2027; a $700,000 single-award Blanket Purchase Agreement with the Department of the Interior's Bureau of Reclamation (February 2024–April 2029) for expert witness support across infrastructure and water resource management litigation; and a $320,000 BPA call from the Bureau of Reclamation for expert witness services on the Grand Coulee Fire Station project through February 2027. Individual purchase orders from the U.S. Attorney's Offices range from under $2,000 to over $40,000 in ceiling value, structured on labor-hours or time-and-materials pricing.
Customer concentration is extreme and narrow. The Department of Justice dominates Rimkus's federal footprint: the U.S. Attorney's Offices account for 112 of 147 awards (76% of award count) and $1.9 million of combined potential value, while the Civil Division holds 7 awards and $851,000 combined potential value. The Department of the Interior's Bureau of Reclamation is the only other material customer, holding 3 awards and $1 million combined potential value. Together, these two agencies drive 92% of all award count and 66% of combined potential value. The remaining six customer agencies—including the Equal Employment Opportunity Commission, the Missile Defense Agency, the Treasury Internal Revenue Service, and the Department of Labor—account for fewer than 10 awards combined and minimal dollar exposure.
The vendor sits on a single parent vehicle: a Bureau of Reclamation BPA (140R1024A0001) with 2 task orders and $320,000 combined potential value. The vast majority of Rimkus's federal work is direct purchase orders or calls against unnamed standing agreements rather than formal IDIQs or GWACs.
Activity has been growing. Award volume increased from 11 in 2022 to 23 in 2024, before moderating to 13 in 2025 and 12 in 2026. Twenty-one awards (combined potential value $1.3 million) reach ultimate completion within the next twenty-four months, creating recompete exposure across the Department of Justice and Bureau of Reclamation portfolios. The Service Contract Inventory data carries minimal signal — only 4 SCI records across FY2022–FY2024, with zero invoiced revenue recorded in the SCI dataset, reflecting that the vast majority of Rimkus's federal work is either below the $150,000 SCI reporting threshold or classified as goods/products rather than services under SCI taxonomy. This sparse SCI coverage indicates the award database, not SCI, is the authoritative source for Rimkus's federal activity.
Rimkus operates through two named subsidiaries: Rimkus Analytics, L.L.C. (for-profit) and Core Human Factors, Inc. (Subchapter S corporation). The corporate structure suggests capability diversification beyond the pure expert witness role, though the award history is dominated by litigation support work. Work is performed in Houston, Texas, with occasional engagement in other locations (Shreveport, Louisiana appears in one award description). The vendor has held a SAM registration since December 2004, indicating sustained federal contracting presence, though the award concentration with the U.S. Attorney's Offices and relatively modest dollar scale ($5.8 million combined potential value across 147 awards, or roughly $39,500 per award on average) reflects a niche, stable practice rather than a broad federal systems integrator.
