What STRATA does
STRATA is a privately held geotechnical engineering and construction inspection firm headquartered in Boise, Idaho, founded in 1974 as a mobile laboratory and now operating six offices across Idaho, Utah, and the Pacific Northwest with over 110 team members. The company delivers three core service lines: Geotechnical Engineering Services (foundation evaluation, pavement design, geohazard studies, slope stability and settlement analyses, soil improvement, and forensic evaluation); Construction Inspection and Testing Services (special inspections, materials laboratory testing, quality assurance/control, concrete mix designs); and Laboratory Testing Services backed by three AASHTO-accredited laboratories in Post Falls, Boise, and Idaho Falls (Idaho) and Sandy/Salt Lake City (Utah), supplemented by a fleet of mobile laboratories. The firm also deploys a proprietary internal reporting platform, MetaField, for real-time electronic reporting, deviation tracking, and equipment/personnel certification management, and holds ICC Preferred Education Provider status.
STRATA serves a horizontal set of eight market segments — Commercial, Education, Energy, Government, Healthcare, Transportation, Water, and Industrial — with named clients spanning school districts, utilities (Avista, Pacificorp, Basin Electric), engineering firms (J-U-B Engineers, HDR), construction firms (Hoffman Construction), healthcare systems (St. Luke's), retail (Les schwab), and higher education (Eastern Washington University). Revenue is generated through project-based professional services billed to government agencies, commercial developers, healthcare facilities, educational institutions, energy providers, transportation organizations, and industrial clients across the inland northwest. The company pursues a sales-led go-to-market model built on long-term collaborative relationships with owners, developers, engineers, architects, and contractors.
In 2025, STRATA was acquired by Knife River Corporation (NYSE:KNF) for $454 million as part of Knife River's strategy to expand its geographic and operational scale in aggregates and ready-mix concrete; STRATA now operates as a subsidiary within that publicly traded construction materials conglomerate. Pricing is quote-based and not publicly disclosed, and STRATA does not publicly report revenue figures.

STRATA competitors and assessment
Company assessmentDirect peers
- Kleinfelder: One of the largest US geotechnical, environmental, and construction materials testing firms. Directly comparable service portfolio (geotechnical engineering, CMT, special inspections) with similar federal/state DOT and utility client base, but at much larger national scale.
- Terracon: National geotechnical and environmental engineering consulting firm with a similar mix of geotechnical engineering, construction materials testing, and special inspection services. Closely comparable operating model with multiple AASHTO-accredited labs and similar end-market exposure.
- GeoEngineers: Pacific Northwest-based geotechnical and environmental engineering firm headquartered in Redmond, WA. Directly comparable service offering and overlapping geographic footprint in inland NW and Pacific NW markets.
- S&ME: Mid-size engineering firm providing geotechnical engineering, construction materials testing, and environmental services across the Southeast and Midwest. Directly comparable service mix and lab accreditation footprint.
- Braun Intertec: Employee-owned geotechnical, environmental, and construction materials testing firm operating primarily in the Midwest and Mountain West. Directly comparable services, AASHTO-accredited labs, and similar eight-vertical end-market exposure.
Broad incumbents
- AECOM: Global engineering and infrastructure consulting firm offering geotechnical and construction services as part of a much broader portfolio. Competes for large federal/state infrastructure pursuits that STRATA cannot cover alone.
- WSP: Global professional services firm (parent of Golder Associates and Wood Environment & Infrastructure) with extensive geotechnical and earth sciences capabilities. Competes for large-scale transportation, energy, and water infrastructure programs.
- Stantec: International engineering, architecture, and environmental services firm with a North American geotechnical practice. Competes for water, transportation, and community development geotechnical engagements.
- NV5 Global: Technical engineering and consulting firm with infrastructure, environmental, and geospatial practices including geotechnical and construction materials testing services that overlap with STRATA's offering.
Others
- Knife River Corporation: Parent company and strategic acquirer (NYSE:KNF) focused on aggregates, ready-mix concrete, and construction materials. Acquiring STRATA vertically extends Knife River into the upstream geotechnical/CMT services that feed its materials businesses.
