(EDI), a Minority-Owned, Woman-Owned, and Disadvantaged Business Enterprise (MBE, WBE, DBE), providing multidiscipline engineering headquartered in Chicago, IL has reached an agreement to acquire Hamilton Consulting Engineers (HCE), a Joliet-based civil engineering and professional land surveying firm.

The firm soon developed into a full-service municipal and transportation engineering firm, and, with current leadership and ingenuity as a base, HCE is today a Woman-Owned and Disadvantaged Business Enterprise (WBE, DBE) able to  perform consulting services for transportation design and planning; construction management; design and planning services for wastewater collection, wastewater treatment, water supply, water treatment and stormwater management; surveying, CAD/GIS and the related fields of forensic engineering and diversity program management.

This acquisition will expand the resources, knowledge and experience of EDI and provide added value and continued exceptional professional service to EDI and HCE clients. The acquisition is an excellent fit of talent and resources that will increase capacity and maintain diversity of our firms and workforce.

EDI’s Acquisition of HCE will continue and expand service operations across the combined geographic area, with the same quality civil engineering and land surveying services HCE has provided for the past 68 years, and the same quality civil engineering, environmental engineering, industrial hygiene, and land surveying services EDI has provided for the past 32 years. EDI looks forward to welcoming HCE employees to our team and plans to retain their office location, with current HCE leader and Chairman/CEO, Kristen Hamilton and President/Principal Engineer, Howard Hamilton, PE joining EDI’s Management team.
