Marquess & Associates

What Marquess & Associates does

Marquess & Associates, Inc. is a privately held, multi-disciplinary consulting engineering firm headquartered in Medford, Oregon, founded in 1957 by Walter J. Marquess, P.E. and incorporated in 1969. The firm delivers civil, structural, mechanical and fire protection, electrical, and geotechnical engineering alongside special inspections and construction materials testing, plus drone-based aerial inspections. The full suite is delivered in-house from a single Medford office (18 employees as of the latest disclosure), allowing principals — three of four are registered Professional Engineers — to remain directly engaged in project design and construction administration rather than outsourcing disciplines to sub-consultants.

The firm operates as a project-based B2B professional services practice. Revenue is generated through engineering consulting fees for feasibility studies, design, and construction administration, plus on-site and laboratory materials testing and special inspection services for concrete, soil, masonry, steel, and fireproofing. Technical delivery relies on standard industry tools (AutoCAD Civil 3D, Revit, Carrier HAP, Trimble S6, NDT equipment) and an in-house materials testing laboratory; technology functions as productivity infrastructure rather than a differentiator. Customers are concentrated in Southern Oregon and northern California and span private developers, contractors, architects, healthcare systems (Asante, Providence), financial institutions (People's Bank), and government clients (Josephine County, county facilities).

Go-to-market is relationship-driven: the firm reports that over 80% of business comes from repeat clients, supported by multi-decade engagements with Lithia Motors (30+ years), The Abell Architectural Group (since 1982), and Outlier Construction (last decade), among others. Marketing is minimal and executed through the website portfolio, client testimonials, and direct inquiry. In 2024, Marquess & Associates joined AKS Engineering & Forestry together with Construction Engineering Consultants and CSA Planning, creating a broader Southern Oregon multi-firm platform — and the company's own website now identifies it under the AKS Engineering & Forestry brand.
