About the company
Kleinschmidt Associates, doing business as Kleinschmidt Assoc, is a for-profit environmental and hydropower engineering consulting firm based in Pittsfield, Maine, that delivers expert witness services, engineering design, and aquatic ecosystem restoration consulting to federal agencies as a prime contractor (89% of recent awards) with no SBA set-aside certifications, competing on full-and-open basis across civilian and water-resource agencies.
The vendor's customer concentration is extreme and narrow. The Department of Justice Environment and Natural Resources Division dominates the portfolio with 17 awards (67% of award count) valued at $5.6 million combined potential value — nearly all classified as expert witness services on time-and-materials purchase orders. The next four customers — NOAA, Army Corps of Engineers, Bureau of Reclamation, and Tennessee Valley Authority — account for only 13 awards combined. Potential-value ranking amplifies DOJ's dominance; GSA Federal Acquisition Service carries a single $2 million task order on a Multiple Award Schedule, but DOJ still represents the largest single customer by dollars ($5.6 million across 17 awards). This customer concentration creates substantial recompete risk: five awards (combined potential value $2.2 million) reach ultimate completion inside the next twenty-four months, with the majority expiring by February 1, 2029 or April 30, 2030.
Kleinschmidt Assoc's primary service line is expert witness support for DOJ environmental litigation. Recent representative prime work includes a $820.8 thousand time-and-materials purchase order from DOJ Environment and Natural Resources for expert witness services (awarded September 2022, completing February 2027), a $640.2 thousand similar order (September 2023, completing March 2028), and a $435 thousand order (July 2025, completing September 2030). Beyond DOJ expert witness work, the vendor performs engineering design and biological analysis on aquatic ecosystem and fish-passage projects. As a subcontractor, Kleinschmidt Assoc supplies CFD (computational fluid dynamics) modeling, fish-passage design services, and aquatic-biology analysis to HDR Engineering, Tetra Tech, Stanley Consultants, and Industrial Economics on projects for Army Corps of Engineers, NOAA Fisheries, Bureau of Reclamation, and the National Marine Fisheries Service.
Recent subcontract work includes fish-passage design and quality-control services under Stanley Consultants for Lock and Dam 22 Navigation and Ecosystem Sustainability Program (October 2022), DDR (Dexter Fish Facility design) CFD modeling and biology sections under Tetra Tech (August 2024), and A-E design services for Rathbun Lake fisheries aquatic ecosystem restoration under HDR Engineering (September 2025). The vendor's capability portfolio, grounded in primary NAICS categories All Other Legal Services (17 awards) and Engineering Services (7 awards), centers on specialized technical testimony and design for complex water-resource and environmental infrastructure matters. Kleinschmidt Assoc maintains established relationships with the Army Corps of Engineers and NOAA Fisheries dating to SAM registration in 2002, positioning it as a trusted sub on federal ecosystem and navigation projects. Activity has remained relatively flat year over year — ranging from two to six awards annually over the past five years — reflecting a mature, stable customer base rather than growth trajectory.
