What David Evans and Associates does
David Evans and Associates, Inc. (DEA) is a Portland, Oregon-headquartered, employee-owned engineering, design, surveying, and environmental consulting firm founded in 1976. The company operates through six service divisions — Energy, Land Development, Transportation, Water and Environment, Surveying and Geomatics, and Marine Services — serving federal, state, and local government agencies (USACE, NOAA, NPS, BPA, EPA, state DOTs, cities, ports, and housing authorities) plus a limited set of private-sector clients such as healthcare systems. Revenue is generated through professional service fees on time-and-materials or fixed-fee contracts, typically acquired through qualifications-based selection (QBS), competitive RFPs, and multi-year on-call consulting agreements.
The firm's technical stack centers on geospatial and survey instrumentation rather than software products: mobile 3D laser scanning, subsurface utility locating (electromagnetic and ground penetrating radar), small unmanned aerial systems (sUAS), GIS integration across Bentley, Autodesk, and Esri platforms (DEA holds Esri Silver Tier status), and Civil Information Modeling / BIM for clash detection. The Marine Services Division is a notable differentiator, owning and operating survey platforms ranging from unmanned shallow-water vehicles to the 82-foot S/V Blake, equipped with multibeam bathymetric sonar, side scan sonar, and towed platforms, supporting federal hydrographic, nautical charting (NOAA CatZOC A1), port, and emergency-response work. Quantified outcomes include reducing corridor survey time from weeks to days without lane closures and enabling rapid port reopening after major storms.
Go-to-market is sales-led and reputation-driven: project awards and case studies published on the corporate website, industry conference participation, awards from ACEC, ASCE, and state/regional bodies, and a subconsultant/vendor prequalification portal for delivery capacity. The company is structured around an employee-ownership model (the Officer Program) and has expanded through acquisitions, most recently TranTech Engineering LLC in September 2024 (adding 50+ employees in Washington) and previously Elcon Associates, Inc. Revenue, financials, and pricing are not publicly disclosed, and no AI/ML capabilities are described in available materials.

David Evans and Associates competitors and assessment
Company assessmentDirect peers
- Parametrix: Mid-size Pacific Northwest employee-owned engineering firm offering transportation, water, environmental, and surveying services. Most direct comparable given shared regional base, similar size band, employee-ownership structure, and overlapping client base with state DOTs and municipalities in the West.
- Mead & Hunt: Mid-size employee-owned engineering and consulting firm (~1,500+ staff) providing transportation, water, environmental, and construction services across the U.S. Closely comparable in employee-ownership culture, service mix, and pursuit of multi-disciplinary infrastructure work for public-sector clients.
- HDR Inc. Employee-owned engineering and design firm with strong transportation, water, environmental, and marine/coastal practices. Overlaps with DEA on transportation, water, and surveying; larger and broader geography but a directly comparable business model and client set.
- Kimley-Horn: Large, fast-growing employee-owned engineering firm with significant land development, transportation, and environmental practices. Very similar culture (employee-ownership, top-tier workplace) and overlapping service portfolio; larger scale but a key direct peer.
- POWER Engineers: Employee-owned engineering and environmental services firm with comparable size band focused on infrastructure including transmission, energy, and federal clients. Overlaps with DEA on energy (transmission) and federal agency work; complementary specialization.
- T.Y. Lin International: Mid-size engineering firm specializing in bridges, transportation, and infrastructure. Closely comparable on transportation/structures work and government transportation department client overlap; relevant given DEA's TranTech-driven expansion into bridges and structures.
- Brown and Caldwell: Employee-owned environmental and engineering consulting firm specializing in water/wastewater and environmental planning. Direct overlap with DEA's Water and Environment division and similar employee-owned culture; smaller scope but a strong comparable for the water practice.
Broad incumbents
- Stantec: Large global multi-disciplinary engineering, environmental, and surveying firm with established Pacific Northwest presence. Overlaps with DEA across transportation, water, environment, and surveying services but at materially larger scale and broader geography.
- WSP USA: Very large global engineering and professional services incumbent operating across transportation, environment, water, and property. Competes with DEA for federal and large state DOT contracts but offers a much broader service portfolio.
- AECOM: Global engineering and infrastructure giant with transportation, environment, water, and design practices competing for the largest federal infrastructure programs. Much broader and larger than DEA but a relevant incumbent for the largest public-sector bids.
