Associated Engineers

What Associated Engineers does

Associated Engineers, Inc. (AEI) is a privately held, multi-disciplined consulting engineering firm founded in 1958 and headquartered in Madisonville, Kentucky, with additional offices in Owensboro and Lexington. The firm offers an integrated portfolio of twelve engineering service lines spanning civil, structural, geotechnical, environmental, and mining engineering, complemented by land surveying, materials testing, special inspections, construction monitoring, forensic engineering, drilling, and steel detailing. AEI serves both private-sector clients — including architects, developers, private businesses, and mining operators — and public-sector clients including government agencies, institutions, and municipalities across eight U.S. states (Kentucky, Indiana, Ohio, West Virginia, Illinois, Tennessee, Mississippi, and Alabama), with the ability to obtain licensure in additional jurisdictions as needed.

The firm delivers its services through a team of Professional Engineers, Professional Surveyors, Professional Geologists, Engineers-In-Training, Quality Assurance Engineers, designers, detailers, geologists, surveyors, and technicians, leveraging industry-standard design and analysis tools including AutoCAD (with Survcad and Architectural Desktop), SDS/2 for structural detailing and BIM, RAM Structural Systems for 2D/3D structural analysis, RetainPro 2007 for retaining wall and foundation design, Shake2000 for seismic soil analysis, and GPS/GIS-enabled surveying equipment. AEI also operates an in-house materials testing laboratory that supports concrete, masonry, soil, aggregate, and steel testing, providing single-source delivery of complex projects from feasibility and permitting through design, construction monitoring, and special inspection.

AEI generates revenue through professional services fees on a project basis, with pricing determined by scope, complexity, and client requirements rather than disclosed standard rates. The firm employs a sales-led, direct-client go-to-market motion, supplemented by a content-marketing website and active participation in industry associations including ACI, AISC, ASCE, NSPE, SEAOK, SEI, and USGBC. The company has expanded historically through acquisition, notably the 2004 purchase of Danco Engineering which added mining and heavy structural capabilities, followed by office openings in Owensboro (May 2006) and Lexington to extend geographic reach within and beyond Western Kentucky.
