SEECO

What SEECO does

SEECO is a privately-held civil and environmental engineering consulting firm headquartered in Tinley Park, Illinois, operating continuously since 1970 under common ownership across three affiliated entities: SEECO Consultants, Inc. (core civil, geotechnical, and structural engineering and construction materials quality control), SEECO Environmental Services, Inc. (SES, environmental investigations, remediation design, and regulatory compliance), and SEECO Construction Services, Inc. (SCS, union materials testing and construction field monitoring). The firm serves federal, state, and municipal government agencies (IDOT, MWRD of Greater Chicago, U.S. Department of Veterans Affairs, Public Building Commission of Chicago, Illinois Capital Development Board) as well as industrial, developer, commercial, lender, and municipal clients across the Midwest region.

The company's technical platform centers on owned physical assets rather than software: a mobile drilling fleet of more than twelve rigs (truck-mounted, ATV-mounted, skid-mounted, plus floating plants and a motorboat for offshore work), a mobile environmental laboratory for turnkey site characterization, and a geotechnical and materials testing laboratory approved by five government authorities. Service delivery is anchored by licensed Professional Engineers, civil/structural/geotechnical/environmental engineers, chemists, and Local 150 union-certified field engineers and technicians holding Level III IDOT testing qualifications, with a multi-tiered report review system culminating in a licensed engineer's final review.

Commercially, SEECO operates a B2B professional services model with project-based quoting and dedicated project managers serving as single points of contact from proposal through completion. Distribution is primarily direct, enterprise-level engagement with government and large private-sector clients in the Midwest. Revenue streams are diversified across geotechnical consulting, environmental consulting, and construction materials testing, with no disclosed pricing, no public funding, and no digital or content marketing channels beyond a basic informational website.
